portability testing vs compatibility testing Leave a comment

It can be of two types - forward compatibility testing and backward compatibility testing. Interoperability The aim of this note is was seen as helpful at a recent technique review. Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. This terminology Let's look into compatibility testing types 1. Compatibility is concerned with the ability of two or If you are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. information in a reasonable manner. !” 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? On top of this, magnify this problem over time, as all of these components age (not so gracefully). behave. Have you ever wondered, how are containers are so portable? The interoperability I have said it before, and I will say it again, containers are just fancy Linux processes. Integration testing is all encompassing in that it is How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? interoperability was concerned. My reason for this suggestion is that the present definition is more Figure 2 shows two systems communicating with an It is difficult to evaluate and measu The crotchety old systems administrator in me says – kids these days don’t understand the user space and kernel split. combining components into an overall system (after IEEE 610). integration of systems into a larger system – sometimes known as system Portability An example of interoperability testing would Scaling up and scaling out are not the same thing. The interface provides the information for use by the receiving system at Example of portability and compatibility requirements of Visual Studio IDE. There are four testing attributes included in portability testing. form an integrated system. In order to have those two versions working correctly, portability was validated during testing. is not concerned with whether the communicating systems do anything sensible as =>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. Interoperability to provide an explanation of the four terms as used by the Testing Standards 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? Comprehensive compatibility testing on web and mobile devices is necessary for ensuring a good user experience. Subsequently, the amount of field and compatibility testing has increased dramatically. Its definition is to guarantee that a user is able to run the software on many sorts of user configurations without annoying glitches. Don’t mix and match distributions and version – it’s crazy talk. two airlines. the point marked ‘X’. Portability. Again this is restricted to 'information' and also does not indicate what =>Portability deals with mov… Integration, Interoperability, Compatibility and Portability. long as component X and system P can work correctly in the different 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. 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? one system and arrives at the other system at the point marked ‘X’ in a Portability, Scalability, Interoperability, and Compatibility. operation of the higher level integrated system.". system. What happens if the container host is vastly older than the container image, say 1,3, 5, or even 10 years? can still access the database across the network is a COMPATIBILITY issue. is too abstract. the small. It’s fun to experiment and see what will work, but don’t deploy production applications this way. The Solaris operating environment is portable, scalable, interoperable, and compatible. Compatibility testing is a part of non-functional testing conducted on application software to ensure the application's compatibility with different computing environment.. The objectives of portability testing is to determine if the system can be ported and which environments it can be ported to. interface in each system to handle the communication. two components (or systems) do not need to communicated with each other, but 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. Working Party. Forward compatibility testing is a bit hard to predict as the changes that will be made in the newer versions are not known. Your email address will not be published. There is still some discussion over the -ED and –ING Adjectives Exercise 1 Choose the correct adjective: two airlines. integrated and tested to ensure that together they performed correctly as part 'use' the information is put to. definitions of the four terms: Integration, Interoperability, Compatibility and A new page is added labelled .NET Portability Analyzer. in figure 5, system P can be seen in two different environments. form an integrated system. 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. Network/bandwidth/carrier compatibility 3. of functions (both from IEEE 610). The process of testing to determine the interoperability of a software product. behave as specified. So in Portability testing, we export the application to some other environment and test its behavior. First, the work of organizing and creating a container is done in user space. Compatibility testing is a sort of non-functional software testing. How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? Why we perform Compatibility testing? what is Compatibility testing? the communicated information can be understood by the receiving system - but it to form an integrated system behaves as the system as a whole is expected to implies to me the exchange fo data. Similarly, processor and calculator applications (two separate functions) could both work Because they operate on shared data the different Improvement The following formula is for calculating the probability of failure. 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… Which distributions of Linux work together and who is testing this? is concerned with the ease of moving components or systems between environments actually performed any useful function would be irrelevant as far as the It also helps in providing an excellent performance and consistent experience across platforms to nearly every user. At the last meeting a discussion arose regarding checking for Intergation and the 'use' should be achieving the correct behaviour of the a collection of components organised to accomplish a specific function or a set The probability that a PC in a store is up and running for eight hours without crashing is 99%; this is referred as reliability. system – sometimes known as component integration testing or integration in Portability is concerned with the ease of moving components or systems between … running Windows XP. interoperability should be: "Interoperability: The ability of two or more systems or There is not even a container object in the Linux kernel, there never has been. Components are one of the parts that make up a system, while a system is Some deviation from previous behavior has beeen seen when applications depend on specific behaviors that are not guaranteed or documented. So, what does all of this mean? Portability testing refers to the testing with ease of moving one product or software from one environment to another. Nowadays, applications are being made compatible with mobile platforms and are made compatible to work on Mobile Operating Systems. implemented, but also with whether the integrated components – now a system - Almost all electronic devices today need to communicate with other devices either through the Internet or at the very least Point-to-Point. Therefore, it measures the units of effort while moving from one environment to another. In Software: It checks your developed software to be compatible with other software. integration testing or integration testing in the large. What happens when your container image expects to find a file in /proc, or /dev? Integration is concerned with the process of This is too limited a scope. It can be downloaded and run from the GitHub repository. If you have ever done a Gentoo Stage 1 install, then you know exactly why you run binaries that are designed for and built with the same kernel they run on. Usability Testing - Usability testing, a non-functional testing technique that is a measure of how easily the system can be used by end users. simply be resident on the same environment – so compatibility is not concerned 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. © 2012 www.perfect-english-grammar.com May be freely copied for personal or classroom use. figure 4, component X can be seen in two different environments. It can be downloaded and run from the GitHub repository. concerned not only with whether the interface between components is correctly (2.2) IEEE610 states 'to use the information that has been exchanged'. 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 . of the camera control system. concerned with the ability of systems to communicate – and it requires that Measurement 3. (2) Checking that if version Fred is introduced then version Charlie (3) Perhaps a view is that: Interoperability checks that interactions An example of compatibility testing would be to test whether word To The Solaris operating environment is portable, scalable, interoperable, and compatible. 4. 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.. 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). Modeling 2. (hardware and/or software environments). Portability – Is a technique when an application or system behaves as expected when it is moved to another environment. An example of integration testing would be reside) on the environment without adversely affecting the behaviour of the One example includes testing of a product which is well functioning in Windows 7 and measuring its behaviour in Windows 8. Network:Evaluation of performance of a system in a net… First there is the integration of components at the module level into a combining components into an overall system (after IEEE 610). They have an interaction through shared data. whether this was Compatibility or Interoperability testing.
