Second, there is no layer of abstraction, like virtualization. Figure 3 shows two components in the same environment. processor and calculator applications (two separate functions) could both work =>Portability deals with mov… Example:A word processor and a calculator running on the same OS such as Windows 10 can be said to be compatible with each other as running one application will not affect the behavior of the other application. Have you ever wondered, how are containers are so portable? What happens if your container does more than just file open(), say it needs access to dedicated hardware? What happens if the docker daemon triggers a kernel bug when it is trying to create a container on a version of a kernel for which it was not tested or certified to work with? The points given below will briefly distinguish the differences between Portability and Compatibility. This behavior will cover both functional and non-functional aspects of the integrated system. what is Compatibility testing? Why Portability is Not the Same Thing as Compatibility The Container Host *is* the Container Engine, and Container Image Compatibility Matters. Return Visual Studio and navigate to Tools > Options. a whole. is not concerned with whether the communicating systems do anything sensible as So in Portability testing, we export the application to some other environment and test its behavior. form an integrated system. Interoperability is an aspect of Features Compatibility testing is a type of software testing used to ensure compatibility of the system/application/website built with various other objects such as other web browsers, hardware platforms, users (in case if it’s very specific type of requirement, such as a user who speaks and can read only a particular language), operating systems etc. They don’t understand the Unix design principles. Don’t mix and match distributions and version – it’s crazy talk. explain the terms then two basic entities are required:  They are compatible with each other as long as both can run (or simply Operating system Compatibility Testing - Linux , Mac OS, Windows. To a collection of components organised to accomplish a specific function or a set Mobile Testing class • State of the Mobile – Stats – Technology • Mobile testing challenges • Testing approach (+ exercises) – Functionality – Performance – Compatibility – Usability – Security – Interoperability – Survivability and recovery – User acceptance – Production monitoring • Mobile Test Lab • … Figure 1 shows two components interacting to Portability Testing is the type of Software Testing which is carried out to determine the degree of ease or difficulty to which a software application can be effectively and efficiently transferred from one hardware, software or environment to another one.. (2.2) IEEE610 states 'to use the information that has been exchanged'. same environment (after IEEE 610). How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? INTEGRATION testing. Information may be used to support shelf life and expiration date claims. That means x86_64 containers must run on x86_64 hosts – ARM containers must run on ARM hosts – Microsoft Windows containers must run on Microsoft Windows hosts. I am here to break it to you – it’s not magic. Comprehensive compatibility testing on web and mobile devices is necessary for ensuring a good user experience. of the camera control system. A suggested Save yourself the pain, if you are an Ubuntu 16 shop, run the docker engine that comes with Ubuntu 16, and run Ubuntu 16 container images. environments then they are considered to be portable components and systems. The Solaris operating environment is portable, scalable, interoperable, and compatible. In order to have those two versions working correctly, portability was validated during testing. Forward Compatibility Testing– Testing of the application or software in new or upcoming versions. of functions (both from IEEE 610). version Charlie can operate on the data correctly is INTEROPERABILITY or Interoperability Stated another way, the docker daemon, libcontainer, runc, RKT, etc handle a user’s API call, and turn it into a function call (clone instead of fork or exec) to the kernel, and voila, a process is created in the kernel. We are still in early days and haven’t ran into even a small percentage of the problems that we will as this technology ages – when we are using kernels, container engines, and images which are of vastly different ages from built by Linux distributions which take wildly different approaches to building kernels and binaries, we will see more and more problems. As long as I run the docker daemon on all of my hosts, everything will just work right? (2.1) IEEE610 refers to 'exchange information'. interoperability should be: "Interoperability: The ability of two or more systems or Compatibility testing is to check the application working in the same way for all platforms. Vertical vs horizontal scaling. At the last meeting a discussion arose regarding checking for There is still some discussion over the Intergation and the 'use' should be achieving the correct behaviour of the Compatibility testing is nonfunctional testing in which environment application on which the application can be run successfully is tested.It is also checks whether your application can run successfully on different platforms or environments. is therefore involved with the interfaces (as is integration) but not with It’s fun to experiment and see what will work, but don’t deploy production applications this way. Well, it means two very important things. It is also known as forward compatible. It can be downloaded and run from the GitHub repository. The aim of this note is to form an integrated system behaves as the system as a whole is expected to Portability. whether the communicating systems as a whole behave as specified. Portability is concerned with the ease of moving components or systems between … Historically, these differences have been difficult to find, and so we are introducing the .NET Compatibility Diagnostics to help identify these changes during .NET version u… © 2012 www.perfect-english-grammar.com May be freely copied for personal or classroom use. An example of compatibility testing would be to test whether word Some deviation from previous behavior has beeen seen when applications depend on specific behaviors that are not guaranteed or documented. It also helps in providing an excellent performance and consistent experience across platforms to nearly every user. Compatibility testing is also known as portability testing. There is a much tighter coupling between the the container image, container engine, and container host than most people think. definitions of the four terms: Integration, Interoperability, Compatibility and Updates to the .NET Framework 4 are delivered as highly-compatible in-place updates, which helps keep users’ applications running on the latest and most secure versions of the .NET Framework. In with interoperability. It would seem, that even Docker agrees, as they developed the Moby project and LinuxKit to be able to tightly couple these three things (host, engine, image) in what amounts to essentially a Unikernel like structure. The interface provides the information for use by the receiving system at Integration, Interoperability, Compatibility and Portability. be where flight information is passed between the (separate) booking systems for So we say that these 2 applications are compatible with each other. Thus interoperability testing is a subset of integration testing. Compatibility testing is a part of non-functional testing conducted on application software to ensure the application's compatibility with different computing environment.. Portability, Scalability, Interoperability, and Compatibility. It is difficult to evaluate and measu (yes, this can happen). is concerned with the ease of moving components or systems between environments An testing is concerned with whether the two components when combined (integrated) Finally, if you want to test your code outside Visual Studio, you can always run it from the command line using the console app. is too abstract. It can be downloaded and run from the GitHub repository. Two Define compatibility with other applications, including 3rd parties. So, what does all of this mean? concerned with the ability of systems to communicate – and it requires that them in this mode. I have said it before, and I will say it again, containers are just fancy Linux processes. Hardware compatibility 2. whether this was Compatibility or Interoperability testing. DockerCon 2017: Austin: The Cube Interview, Why Portability is Not the Same Thing as Compatibility, IDG Contributor Network: What does container portability really mean? combining components into an overall system (after IEEE 610). Compatibility is concerned with the ability of two or Example of compatibility requirements: Integration testing is all encompassing in that it is reside) on the environment without adversely affecting the behaviour of the two airlines. Improvement The following formula is for calculating the probability of failure. Because they operate on shared data the different Compatibility with diff… How do we detect performance regressions in the kernel or glibc? Why we perform Compatibility testing? What happens if your container expects a certain kernel module to be loaded and running? The docker daemon provides no compatibility guarantees – any incidental compatibility is provided by the Linux kernel and Glibc. and portability are significant considerations in relation to the use of cloud services, but there is also confusion and misunderstanding of exactly what this entails. meant the same thing to the target system as the sending system. Measurement 3. They have an interaction through shared data. It would not test whether the target system subsequently used the booking For instance, some software can only be used on a Windows machine, while others have a Mac version as well. to provide an explanation of the four terms as used by the Testing Standards 3. (b)Invoking a service on another comp/sys that generates either a What happens when your container image expects to find a file in /proc, or /dev? – Portability testing is a testing technique that tests this capability or ease of the device or a software component. view on this is: (1) Checking that if version Fred writes data into a database that in figure 5, system P can be seen in two different environments. If you have any comments on the above article then please use the Portability testing is the process of determining the degree of ease or difficulty to which a software component or application can be effectively and efficiently transferred from one hardware, software or other operational or usage environment to another. Again this is restricted to 'information' and also does not indicate what 'use' the information is put to. information in a reasonable manner. or syscalls that trigger special hardware? can still access the database across the network is a COMPATIBILITY issue. Compatibility testing is a part of non-functional testing conducted on application software to ensure the application's compatibility with different computing environment.. Nowadays, applications are being made compatible with mobile platforms and are made compatible to work on Mobile Operating Systems. un-intended interactions that disrupt normal operation. – Portability is a non-functional aspect of the software and so portability testing is also a non-functional testing technique. state in which it could be used. A quick internet search will tell you that Compatibility Testing covers the following about the intended operating environment for a software product: 1. You might now say to yourself, “yeah, but I run busybox or alpine containers on CentOS/Fedora all the time and it just works!!! interaction in a definition and so rather than 'exchange information' it The Portability Analyzer is offered as a Visual Studio Extension, which analyzes one assembly per project, and as a ApiPort console app, which analyzes assemblies by specified files or directory. There is no intentional interaction between Visual Studio Extension; Introduction to Platform Portability; Changelog; Log Issues and Enhancements. Compatibility Testing is the means to confirm that compatibility requirements have been delivered. Scaling up, or vertical scaling - involves replacing a component of your system with something that works better. First there is the integration of components at the module level into a Network:Evaluation of performance of a system in a net… Example of portability and compatibility requirements of Visual Studio IDE. Usability Testing - Usability testing, a non-functional testing technique that is a measure of how easily the system can be used by end users. Who fixes the kernel, container engine, or container image bugs and tests for regressions? Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. between two systems could be fine, but whether the two systems as a whole As workloads expand beyond simple web servers which really only need to use system calls to open files and open TCP sockets, we will see more and more problems. integration of systems into a larger system – sometimes known as system other. 4. The objectives of portability testing is to determine if the system can be ported and which environments it can be ported to. Portability testing is the testing which establishes the ease or difficulty with which a software product can be moved from one environment to another. Similarly, It is used to ensure interoperability of the system/ web application or mobile application/website built with multifarious objects (browsers, hardware platforms, operating systems and so on). intergated system. Compatibility testing is a type of non-functional testing, the main purpose of which is to verify the correct operation of a product in a specific environment. functions – so is not concerned with integration which would considers whether How is it that all of this just magically works? The SunOS 5.7 product is portable across multiple vendor platforms. The .NET Portability Analyzer helps you determine how flexible your application is across .NET platforms. Before we begin, let’s jog our memory a bit. was seen as helpful at a recent technique review. behave as specified. There is still some discussion over the two components (or systems) do not need to communicated with each other, but implies to me the exchange fo data. Portability testing is the process of determining the degree of ease or difficulty to which a software component or application can be effectively and efficiently transferred from one hardware, software or other operational or usage environment to another. Test definition, the means by which the presence, quality, or genuineness of anything is determined; a means of trial. Modeling 2. What happens if the container image is vastly older than the container host, say 1, 3, 5, or even 10 years? A computer software application is considered portable to a new environment if the effort required to adapt it to the new environment is within reasonable limits. In software, we are normally concerned with integration at two levels. Components are one of the parts that make up a system, while a system is On top of this, magnify this problem over time, as all of these components age (not so gracefully). where the aperture control component and the shutter control component were It could not be agreed Can you say to yourself, honestly, “yeah, I can fix that no problem?” I have seen all of the above happen, and this is just the beginning. implemented, but also with whether the integrated components – now a system - • It is basically the testing of the application or the product built with the computing environment. Compatibility testing is a form of testing which enables the software developing team to deliver a perfect software product which works flawlessly irrespective of the intended computing environments. Trading your processor for a faster one is scaling up. Compatibility testing is conducted in mobile applications for the following reasons:-This testing is performed to make sure that the final app product performs as expected on various mobiles/devices of different make and models; This is a type of non-functional testing whose main aim is to check the compatibility of applications with browsers, mobiles, networks, databases, operating … Compatibility testing is a sort of non-functional software testing. the two components together performed a function correctly. (2.3) Based on the above two points it is suggested that – Freda Rose, Container Portability: Part 3 - Crunch Tools, When it comes to code, be a consumer - Keyrox, When it comes to code, be a consumer | Smart Solution 4.0, When it comes to code, be a consumer - MusicCosmoS, How to Buy a Used Linux Container - Crunch Tools, Open Source in Business 2020: Virtual: Live Panel: Open Source in Business: The Delicate Art of Open Source Product Management, Testing The Latest Container Tools on RHEL8. synchronous or an asynchronous response. Interoperability Finally, if you want to test your code outside Visual Studio, you can always run it from the command line using the console app. Introduction. Your email address will not be published. Network/bandwidth/carrier compatibility 3. A new page is added labelled .NET Portability Analyzer. IEEE 610). Reliability Testing can be categorized into three segments, 1. that it is intended to support work correctly. Integration interference due to a mix of versions of the same applications (present the communicated information can be understood by the receiving system - but it running Windows 98 was then tested to determine whether it worked on a PC Challenges. The probability that a PC in a store is up and running for eight hours without crashing is 99%; this is referred as reliability. Best place to log issues because we do not get notifications from VSIX gallery discussions. First, the work of organizing and creating a container is done in user space. interoperability was concerned. So, apart from these web browser versions, applications are checked on different mobile platforms . one system and arrives at the other system at the point marked ‘X’ in a Compatibility testing is a non-functional testing conducted on the application to evaluate the application's compatibility within different environments. Portability during a role) within a large network environment. combining components into an overall system (after IEEE 610). correctly on a PC at the same time. An example of interoperability testing would Let's look into compatibility testing types 1. !” That’s true, it does work most of the time, but I would like to highlight some questions I have ran into over the last 4-ish years, working with docker, and talking to literally thousands of people about the problems they see: Well, do you have an answer for each of the above questions? If the system must coexist with third-party software or other applications in the software ecosystem, include them. Portability. components to interact in the ways required to implement the correct The aim of this Guide is to provide a clear definition of interoperability and of portability and how these relate to various aspects of cloud computing and to cloud services. The environment here refers to different operating systems, hardware, databases or browsers. akin to interface testing than compatibility testing and this definition Hardware: It checks software to be compatible with different hardware configurations. Figure 1 shows two components interacting to Both Functional Testing and Non-Functional Testing are important in Software Testing to get the expected output results. Interoperability Forward Compatibility Testing. definitions of the four terms: Integration, Interoperability, Compatibility and -ED and –ING Adjectives Exercise 1 Choose the correct adjective: Stability testing using accelerated aging protocols, shall be regarded as sufficient evidence for claimed expiry dates until data from real-time aging studies are available. Integration is concerned with the process of Therefore, it measures the units of effort while moving from one environment to another. Subsequently, the amount of field and compatibility testing has increased dramatically. Software: It checks your developed software to be compatible with other software. The Solaris operating environment is portable, scalable, interoperable, and compatible. versions of the components are in reality different components of the the point marked ‘X’. Working Party. Documentation. Test whether the application can coexist and share other application resources. operation of the higher level integrated system.". Compatibility Testing is a step in the software application testing process that is used to test the non-functional features and the regulatory behaviour of the application with other systems connected to the application. components (or systems) can also be compatible, but perform completely separate explain the terms then two basic entities are required: Integration is concerned with the process of The SunOS 5.7 product is portable across multiple vendor platforms. My reason for this suggestion is that the present definition is more Compatibility Testing. Have you ever wondered, how are containers are so portable? Portability, in relation to software, is a measure of how easily an application can be transferred from one computer environment to another. Its definition is to guarantee that a user is able to run the software on many sorts of user configurations without annoying glitches. Software conforming to an application binary interface (ABI) runs as shrink-wrapped software on all vendor systems with the same microprocessor architecture. If you are setting up a large, distributed systems environment with container orchestration such as Kubernetes, across 100s if not 1000s of hosts, there are already a lot of moving parts – why give yourself another headache to worry about? The two could be working on totally separate data, possibly even totally simply be resident on the same environment – so compatibility is not concerned One example includes testing of a product which is well functioning in Windows 7 and measuring its behaviour in Windows 8. – It tests whether a component of the computer software can be moved from one computing environment to another and with how much ease. (hardware and/or software environments). separate database instance. long as component X and system P can work correctly in the different Figure 3 shows two components in the same environment. This terminology Figure 2 shows two systems communicating with an integration testing or integration testing in the large. An example of interoperability testing would interface in each system to handle the communication. Which distributions of Linux work together and who is testing this? testing is limited to checking that information is correctly communicated from Compatibility testing is a type of testing used to find out ... with different hardware, web browser and database. IEEE 610). form an integrated system. Portability – Is a technique when an application or system behaves as expected when it is moved to another environment. Interactions between components takes other forms including: (a)Triggering actions by another comp/sys. If you are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. integrated and tested to ensure that together they performed correctly as part Portability, Scalability, Interoperability, and Compatibility. feedback concerned not only with whether the interface between components is correctly It is probably inappropriate to try and list each type of example of portability testing would be when a computer game that worked on a PC It means testing team verifies build run on customer expected platforms or not. system. Scaling up and scaling out are not the same thing. Compatibility checks for There are four testing attributes included in portability testing. An example of integration testing would be figure 4, component X can be seen in two different environments. running Windows XP. is suggested the term 'interact' be used. Scope of ASTM F 1980 Provides information for developing accelerated aging protocols. testing would test whether the information reached the target system and still two airlines. (3) Perhaps a view is that: Interoperability checks that interactions The the small. So interoperability is An example of compatibility testing would be to test whether word processor and calculator applications (two separate functions) could both work correctly on a PC at the same time. Forward compatibility testing is a bit hard to predict as the changes that will be made in the newer versions are not known. This is measured in terms of the effort involved in the task. If you are a RHEL 7.3 shop, do the same thing. In fact, different versions of the docker daemon may introduce it’s own compatibility problems, because it’s just a user space daemon and relies on system calls to handle all of it’s work. Interoperability is the ability of two or more Compatibility is one of the many Non-Functional Requirements(NFRs) that are delivered as part of a project. The crotchety old systems administrator in me says – kids these days don’t understand the user space and kernel split. 2. Interoperability is the ability of two or more Co-existence or compatibility: Co-existence is the software product’s capability to co-exists with other independent software products in a common environments sharing common resources . Portability. =>Compatibility deals with whether two or more components can be run in the same environment at the same time without adversely affecting the behavior of each other. Refering to these types of interactions as an 'exchange of information' more systems or components to perform their required functions while sharing the system – sometimes known as component integration testing or integration in form. Would you run binaries from different Linux distributions in production? Portability. behave. I think Dan Woods is right, there is a coming reliability crisis.
