The SunOS 5.7 product is portable across multiple vendor platforms. Figure 1 shows two components interacting to They are compatible with each other as long as both can run (or simply At the last meeting a discussion arose regarding checking for It also helps in providing an excellent performance and consistent experience across platforms to nearly every user. Compatibility testing is a part of non-functional testing conducted on application software to ensure the application's compatibility with different computing environment.. Portability. -ED and –ING Adjectives Exercise 1 Choose the correct adjective: Because they operate on shared data the different 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? See more. what is Compatibility testing? My reason for this suggestion is that the present definition is more 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. Portability, Scalability, Interoperability, and Compatibility. Define compatibility with other applications, including 3rd parties. same environment (after IEEE 610). is concerned with the ease of moving components or systems between environments is not concerned with whether the communicating systems do anything sensible as The objectives of portability testing is to determine if the system can be ported and which environments it can be ported to. Compatibility testing is to check the application working in the same way for all platforms. A suggested of functions (both from IEEE 610). Why Portability is Not the Same Thing as Compatibility The Container Host *is* the Container Engine, and Container Image Compatibility Matters. Therefore, it measures the units of effort while moving from one environment to another. state in which it could be used. 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. 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. Let's look into compatibility testing types 1. was seen as helpful at a recent technique review. An example of compatibility testing would be to test whether word This terminology the communicated information can be understood by the receiving system - but it a collection of components organised to accomplish a specific function or a set the small. to form an integrated system behaves as the system as a whole is expected to Hardware: It checks software to be compatible with different hardware configurations. 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. Operating system Compatibility Testing - Linux , Mac OS, Windows. correctly on a PC at the same time. akin to interface testing than compatibility testing and this definition 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. Integration is concerned with the process of • It is basically the testing of the application or the product built with the computing environment. What happens if the glibc in your application, inside the container doesn’t use hardware accelerated routines because the underlying kernel didn’t enable it? !” 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? Interoperability is the ability of two or more (2.2) IEEE610 states 'to use the information that has been exchanged'. Why we perform Compatibility testing? testing is limited to checking that information is correctly communicated from If the system must coexist with third-party software or other applications in the software ecosystem, include them. 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. versions of the components are in reality different components of the figure 4, component X can be seen in two different environments. 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 • … Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. As systems (or components) to exchange and subsequently use that information (after In order to have those two versions working correctly, portability was validated during testing. I think Dan Woods is right, there is a coming reliability crisis. simply be resident on the same environment – so compatibility is not concerned It could not be agreed 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. To system. Portability – Is a technique when an application or system behaves as expected when it is moved to another environment. They have an interaction through shared data. is suggested the term 'interact' be used. The .NET Portability Analyzer helps you determine how flexible your application is across .NET platforms. DockerCon 2017: Austin: The Cube Interview, Why Portability is Not the Same Thing as Compatibility, IDG Contributor Network: What does container portability really mean? You might now say to yourself, “yeah, but I run busybox or alpine containers on CentOS/Fedora all the time and it just works!!! Compatibility with diff… So, apart from these web browser versions, applications are checked on different mobile platforms . Portability, in relation to software, is a measure of how easily an application can be transferred from one computer environment to another. 'use' the information is put to. The two could be working on totally separate data, possibly even totally Portability testing is the testing which establishes the ease or difficulty with which a software product can be moved from one environment to another. testing would test whether the information reached the target system and still So, what does all of this mean? 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. (hardware and/or software environments). Return Visual Studio and navigate to Tools > Options. Interoperability This behavior will cover both functional and non-functional aspects of the integrated system. Forward Compatibility Testing. Integration, Interoperability, Compatibility and Portability. – Portability testing is a testing technique that tests this capability or ease of the device or a software component. The aim of this note is feedback Again this is restricted to 'information' and also does not indicate what Figure 1 shows two components interacting to Which distributions of Linux work together and who is testing this? The crotchety old systems administrator in me says – kids these days don’t understand the user space and kernel split. Compatibility is concerned with the ability of two or The docker daemon provides no compatibility guarantees – any incidental compatibility is provided by the Linux kernel and Glibc. interaction in a definition and so rather than 'exchange information' it integration of systems into a larger system – sometimes known as system Compatibility Testing is the means to confirm that compatibility requirements have been delivered. Intergation and the 'use' should be achieving the correct behaviour of the 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. 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 . Vertical vs horizontal scaling. environments then they are considered to be portable components and systems. 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. It can be downloaded and run from the GitHub repository. form an integrated system. Challenges. two airlines. the two components together performed a function correctly. whether this was Compatibility or Interoperability testing. behave. If you are a RHEL 7.3 shop, do the same thing. (2.3) Based on the above two points it is suggested that There is still some discussion over the Second, there is no layer of abstraction, like virtualization. Compatibility testing is a non-functional testing conducted on the application to evaluate the application's compatibility within different environments. explain the terms then two basic entities are required:  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. 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. What happens when your container image expects to find a file in /proc, or /dev? Portability. implies to me the exchange fo data. Nowadays, applications are being made compatible with mobile platforms and are made compatible to work on Mobile Operating Systems. First, the work of organizing and creating a container is done in user space. 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. I am here to break it to you – it’s not magic. INTEGRATION testing. them in this mode. So interoperability is can still access the database across the network is a COMPATIBILITY issue. Test whether the application can coexist and share other application resources. 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. reside) on the environment without adversely affecting the behaviour of the Both Functional Testing and Non-Functional Testing are important in Software Testing to get the expected output results. I have said it before, and I will say it again, containers are just fancy Linux processes. It would not test whether the target system subsequently used the booking The Solaris operating environment is portable, scalable, interoperable, and compatible. separate database instance. intergated system. running Windows XP. So we say that these 2 applications are compatible with each other. interface in each system to handle the communication. 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. be where flight information is passed between the (separate) booking systems for Compatibility testing is a sort of non-functional software testing. It can be of two types - forward compatibility testing and backward compatibility testing. (2.1) IEEE610 refers to 'exchange information'. – 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. To It can be downloaded and run from the GitHub repository. Interoperability 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? more systems or components to perform their required functions while sharing the Portability. Would you run binaries from different Linux distributions in production? actually performed any useful function would be irrelevant as far as the systems (or components) to exchange and subsequently use that information (after combining components into an overall system (after IEEE 610). system – sometimes known as component integration testing or integration in whether the communicating systems as a whole behave as specified. Portability is concerned with the ease of moving components or systems between … One example includes testing of a product which is well functioning in Windows 7 and measuring its behaviour in Windows 8. There is not even a container object in the Linux kernel, there never has been. An example of interoperability testing would Portability, Scalability, Interoperability, and Compatibility. components to interact in the ways required to implement the correct Well, it means two very important things. Tons of technical people are out there showing demos of interoperability that doesn’t explain the whole story, and in fact leads people down a really bad path. Scaling up and scaling out are not the same thing. concerned not only with whether the interface between components is correctly combining components into an overall system (after IEEE 610). Have you ever wondered, how are containers are so portable? two components (or systems) do not need to communicated with each other, but The compatibility testing process consists of four phases: Designing test cases and configuration: In this stage, the team designs test cases and an analysis of the environments, software, hardware, and platforms should be taken up to identify the behavior of software. interoperability was concerned. Improvement The following formula is for calculating the probability of failure. form an integrated system. implemented, but also with whether the integrated components – now a system - Components are one of the parts that make up a system, while a system is Settings . After your first round of testing, you can start upgrading your software and hardware by scaling up or scaling out. What happens if your container does more than just file open(), say it needs access to dedicated hardware? Compatibility Testing. The environment here refers to different operating systems, hardware, databases or browsers. Forward compatibility testing is a bit hard to predict as the changes that will be made in the newer versions are not known. the point marked ‘X’. So in Portability testing, we export the application to some other environment and test its behavior. A new page is added labelled .NET Portability Analyzer. Integration testing is all encompassing in that it is interoperability should be: "Interoperability: The ability of two or more systems or It is difficult to evaluate and measu 4. Network:Evaluation of performance of a system in a net… 2. behave as specified. The probability that a PC in a store is up and running for eight hours without crashing is 99%; this is referred as reliability. information in a reasonable manner. Compatibility testing is also known as portability testing. Portability – It tests whether a component of the computer software can be moved from one computing environment to another and with how much ease. Scope of ASTM F 1980 Provides information for developing accelerated aging protocols. to provide an explanation of the four terms as used by the Testing Standards =>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. (yes, this can happen). 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. Software conforming to an application binary interface (ABI) runs as shrink-wrapped software on all vendor systems with the same microprocessor architecture. Test definition, the means by which the presence, quality, or genuineness of anything is determined; a means of trial. 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 … There is still some discussion over the Subsequently, the amount of field and compatibility testing has increased dramatically. concerned with the ability of systems to communicate – and it requires that during a role) within a large network environment. Finally, if you want to test your code outside Visual Studio, you can always run it from the command line using the console app. Compatibility is one of the many Non-Functional Requirements(NFRs) that are delivered as part of a project. It is probably inappropriate to try and list each type of integrated and tested to ensure that together they performed correctly as part (2) Checking that if version Fred is introduced then version Charlie There is no intentional interaction between between two systems could be fine, but whether the two systems as a whole where the aperture control component and the shutter control component were Integration definitions of the four terms: Integration, Interoperability, Compatibility and Comprehensive compatibility testing on web and mobile devices is necessary for ensuring a good user experience. It is also known as forward compatible. Two is too abstract. (b)Invoking a service on another comp/sys that generates either a The interoperability 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. The process of testing to determine the interoperability of a software product. Interoperability is the ability of two or more 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. – Portability is a non-functional aspect of the software and so portability testing is also a non-functional testing technique. 3. An example of interoperability testing would integration testing or integration testing in the large. How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? Usability Testing - Usability testing, a non-functional testing technique that is a measure of how easily the system can be used by end users. Figure 2 shows two systems communicating with an Interoperability is an aspect of operation of the higher level integrated system.". Hardware compatibility 2. Interoperability An with interoperability. Some deviation from previous behavior has beeen seen when applications depend on specific behaviors that are not guaranteed or documented. Its definition is to guarantee that a user is able to run the software on many sorts of user configurations without annoying glitches. two airlines. Interactions between components takes other forms including: (a)Triggering actions by another comp/sys. In In software, we are normally concerned with integration at two levels. The For example, MS Word application should be compatible with other software like MS Outlook, MS Excel,VBA etc. Operating Systems: It checks your software to be compatible with different Operating Systems like Windows, Unix, Mac OS etc. meant the same thing to the target system as the sending system. If you have any comments on the above article then please use the 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.
