Settings . Portability – Is a technique when an application or system behaves as expected when it is moved to another environment. Well, it means two very important things. Scaling up and scaling out are not the same thing. It can be downloaded and run from the GitHub repository. 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 • … system sometimes known as component integration testing or integration in (2.1) IEEE610 refers to 'exchange information'. Portability is concerned with the ease of moving components or systems between … Thus interoperability testing is a subset of integration testing. integration testing or integration testing in the large. Nowadays, applications are being made compatible with mobile platforms and are made compatible to work on Mobile Operating Systems. Portability. Which distributions of Linux work together and who is testing this? is concerned with the ease of moving components or systems between environments functions so is not concerned with integration which would considers whether DockerCon 2017: Austin: The Cube Interview, Why Portability is Not the Same Thing as Compatibility, IDG Contributor Network: What does container portability really mean? This terminology example of portability testing would be when a computer game that worked on a PC Your email address will not be published. figure 4, component X can be seen in two different environments. operation of the higher level integrated system.". Forward compatibility testing is a bit hard to predict as the changes that will be made in the newer versions are not known. Integration is concerned with the process of If you are a RHEL 7.3 shop, do the same thing. How is it that all of this just magically works? components to interact in the ways required to implement the correct 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. was seen as helpful at a recent technique review. An example of integration testing would be form. feedback The interoperability Figure 1 shows two components interacting to Operating system Compatibility Testing - Linux , Mac OS, Windows. For example, MS Word application should be compatible with other software like MS Outlook, MS Excel,VBA etc. =>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. simply be resident on the same environment so compatibility is not concerned Portability testing refers to the testing with ease of moving one product or software from one environment to another. 4. Portability. Both Functional Testing and Non-Functional Testing are important in Software Testing to get the expected output results. Before we begin, let’s jog our memory a bit. Would you run binaries from different Linux distributions in production? Portability testing is the testing which establishes the ease or difficulty with which a software product can be moved from one environment to another. The aim of this note is It could not be agreed Compatibility is one of the many Non-Functional Requirements(NFRs) that are delivered as part of a project. 3. the two components together performed a function correctly. other. Compatibility is concerned with the ability of two or running Windows XP. explain the terms then two basic entities are required: How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? 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. Information may be used to support shelf life and expiration date claims. How do we detect performance regressions in the kernel or glibc? It is difficult to evaluate and measu How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? – Portability is a non-functional aspect of the software and so portability testing is also a non-functional testing technique. Integration, Interoperability, Compatibility and Portability. testing is concerned with whether the two components when combined (integrated) Who fixes the kernel, container engine, or container image bugs and tests for regressions? two airlines. un-intended interactions that disrupt normal operation. A new page is added labelled .NET Portability Analyzer. components (or systems) can also be compatible, but perform completely separate 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. can still access the database across the network is a COMPATIBILITY issue. Why Portability is Not the Same Thing as Compatibility The Container Host *is* the Container Engine, and Container Image Compatibility Matters. This is too limited a scope. (2.3) Based on the above two points it is suggested that of functions (both from IEEE 610). They have an interaction through shared data. 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. So we say that these 2 applications are compatible with each other. interaction in a definition and so rather than 'exchange information' it Portability. Because they operate on shared data the different Have you ever wondered, how are containers are so portable? interference due to a mix of versions of the same applications (present Portability, in relation to software, is a measure of how easily an application can be transferred from one computer environment to another. Compatibility testing is a part of non-functional testing conducted on application software to ensure the application's compatibility with different computing environment.. There is no intentional interaction between separate database instance. Working Party. Compatibility testing is also known as portability testing. 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 … The interface provides the information for use by the receiving system at definitions of the four terms: Integration, Interoperability, Compatibility and system. behave. Components are one of the parts that make up a system, while a system is 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. Compatibility testing is a sort of non-functional software testing. Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. interoperability should be: "Interoperability: The ability of two or more systems or interoperability was concerned. 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… To the small. There is not even a container object in the Linux kernel, there never has been. So interoperability is is therefore involved with the interfaces (as is integration) but not with An example of compatibility testing would be to test whether word behave as specified. What is compatibility testing? If you have any comments on the above article then please use the (yes, this can happen). To At the last meeting a discussion arose regarding checking for 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. In order to have those two versions working correctly, portability was validated during testing. For instance, some software can only be used on a Windows machine, while others have a Mac version as well. Compatibility Testing. Portability Compatibility testing is to check the application working in the same way for all platforms. Figure 1 shows two components interacting to Let's look into compatibility testing types 1. Two more systems or components to perform their required functions while sharing the Interoperability whether this was Compatibility or Interoperability testing. during a role) within a large network 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. meant the same thing to the target system as the sending system. 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. a whole. It is also known as forward compatible. In software, we are normally concerned with integration at two levels. 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. The probability that a PC in a store is up and running for eight hours without crashing is 99%; this is referred as reliability. Reliability Testing can be categorized into three segments, 1. It means testing team verifies build run on customer expected platforms or not. explain the terms then two basic entities are required: Integration is concerned with the process of – Portability testing is a testing technique that tests this capability or ease of the device or a software component. Comprehensive compatibility testing on web and mobile devices is necessary for ensuring a good user experience. Forward Compatibility Testing is a process to verify the behavior and compatibility of the developed hardware or software with the newer versions of the hardware or software. 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. Hardware: It checks software to be compatible with different hardware configurations. It is probably inappropriate to try and list each type of 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. There is still some discussion over the Network:Evaluation of performance of a system in a net… form an integrated system. INTEGRATION testing. Portability, Scalability, Interoperability, and Compatibility. Portability. Integration testing is all encompassing in that it is The 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. 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. An example of interoperability testing would 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. Subsequently, the amount of field and compatibility testing has increased dramatically. It’s fun to experiment and see what will work, but don’t deploy production applications this way. The objectives of portability testing is to determine if the system can be ported and which environments it can be ported to. Second, there is no layer of abstraction, like virtualization. Its definition is to guarantee that a user is able to run the software on many sorts of user configurations without annoying glitches. 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. So, what does all of this mean? How is it that all of this just magically works? synchronous or an asynchronous response. The docker daemon provides no compatibility guarantees – any incidental compatibility is provided by the Linux kernel and Glibc. Scaling up, or vertical scaling - involves replacing a component of your system with something that works better. actually performed any useful function would be irrelevant as far as the form an integrated system. Interoperability be where flight information is passed between the (separate) booking systems for 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? Interoperability is the ability of two or more 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. Why we perform Compatibility testing? Test definition, the means by which the presence, quality, or genuineness of anything is determined; a means of trial. Usability Testing - Usability testing, a non-functional testing technique that is a measure of how easily the system can be used by end users. 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. 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.
