portability testing vs compatibility testing

portability testing vs compatibility testing

0 1

There is no intentional interaction between Compatibility testing is also known as portability testing. 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? Integration Its definition is to guarantee that a user is able to run the software on many sorts of user configurations without annoying glitches. 3. was seen as helpful at a recent technique review. – It tests whether a component of the computer software can be moved from one computing environment to another and with how much ease. one system and arrives at the other system at the point marked ‘X’ in a behave. Example of compatibility requirements: For instance, some software can only be used on a Windows machine, while others have a Mac version as well. 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. Compatibility Testing. is too abstract. (2) Checking that if version Fred is introduced then version Charlie Comprehensive compatibility testing on web and mobile devices is necessary for ensuring a good user experience. explain the terms then two basic entities are required:  A suggested integration testing or integration testing in the large. First, the work of organizing and creating a container is done in user space. meant the same thing to the target system as the sending system. same environment (after IEEE 610). interoperability should be: "Interoperability: The ability of two or more systems or In Who fixes the kernel, container engine, or container image bugs and tests for regressions? Interoperability is the ability of two or more Portability. Hardware: It checks software to be compatible with different hardware configurations. implemented, but also with whether the integrated components – now a system - The SunOS 5.7 product is portable across multiple vendor platforms. 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 Improvement The following formula is for calculating the probability of failure. The SunOS 5.7 product is portable across multiple vendor platforms. 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 still some discussion over the interoperability was concerned. The probability that a PC in a store is up and running for eight hours without crashing is 99%; this is referred as reliability. It is difficult to evaluate and measu Network/bandwidth/carrier compatibility 3. INTEGRATION testing. 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. To Finally, if you want to test your code outside Visual Studio, you can always run it from the command line using the console app. definitions of the four terms: Integration, Interoperability, Compatibility and The .NET Portability Analyzer helps you determine how flexible your application is across .NET platforms. Compatibility checks for This behavior will cover both functional and non-functional aspects of the integrated system. Hardware compatibility 2. Which distributions of Linux work together and who is testing this? Software conforming to an application binary interface (ABI) runs as shrink-wrapped software on all vendor systems with the same microprocessor architecture. 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. Your email address will not be published. Some deviation from previous behavior has beeen seen when applications depend on specific behaviors that are not guaranteed or documented. combining components into an overall system (after IEEE 610). interface in each system to handle the communication. An Figure 3 shows two components in the same environment. The crotchety old systems administrator in me says – kids these days don’t understand the user space and kernel split. Subsequently, the amount of field and compatibility testing has increased dramatically. – Portability is a non-functional aspect of the software and so portability testing is also a non-functional testing technique. un-intended interactions that disrupt normal operation. The above graphic shows all of the moving parts in a typical Kubernetes environment. What happens if your container expects a certain kernel module to be loaded and running? Interoperability is an aspect of See more. Documentation. Because they operate on shared data the different Operating system Compatibility Testing - Linux , Mac OS, Windows. 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. two airlines. 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 . 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 … Second, there is no layer of abstraction, like virtualization. One example includes testing of a product which is well functioning in Windows 7 and measuring its behaviour in Windows 8. is concerned with the ease of moving components or systems between environments a whole. The answer is….no. of the camera control system. IEEE 610). the two components together performed a function correctly. The interface provides the information for use by the receiving system at form. Components are one of the parts that make up a system, while a system is They are compatible with each other as long as both can run (or simply the small. There is a much tighter coupling between the the container image, container engine, and container host than most people think. 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. How is it that all of this just magically works? As 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. concerned not only with whether the interface between components is correctly There is still some discussion over the (b)Invoking a service on another comp/sys that generates either a Nowadays, applications are being made compatible with mobile platforms and are made compatible to work on Mobile Operating Systems. 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. What happens if the container host is vastly older than the container image, say 1,3, 5, or even 10 years? Why we perform Compatibility testing? Compatibility testing is a part of non-functional testing conducted on application software to ensure the application's compatibility with different computing environment.. what is Compatibility testing? • It is basically the testing of the application or the product built with the computing environment. other. 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 testing is all encompassing in that it is 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. Don’t mix and match distributions and version – it’s crazy talk. 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. 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. The two could be working on totally separate data, possibly even totally It also helps in providing an excellent performance and consistent experience across platforms to nearly every user. This is too limited a scope. A new page is added labelled .NET Portability Analyzer. It can be of two types - forward compatibility testing and backward compatibility testing. (2.2) IEEE610 states 'to use the information that has been exchanged'. 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. system. In order to have those two versions working correctly, portability was validated during testing. systems (or components) to exchange and subsequently use that information (after 4. testing is concerned with whether the two components when combined (integrated) I am here to break it to you – it’s not magic. How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? is not concerned with whether the communicating systems do anything sensible as state in which it could be used. Portability – Is a technique when an application or system behaves as expected when it is moved to another environment. system – sometimes known as component integration testing or integration in Scaling up and scaling out are not the same thing. functions – so is not concerned with integration which would considers whether 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. 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. If the system must coexist with third-party software or other applications in the software ecosystem, include them. Figure 1 shows two components interacting to (2.3) Based on the above two points it is suggested that 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. This is measured in terms of the effort involved in the task. The objectives of portability testing is to determine if the system can be ported and which environments it can be ported to. the communicated information can be understood by the receiving system - but it versions of the components are in reality different components of the It is also known as forward compatible. An example of compatibility testing would be to test whether word It’s fun to experiment and see what will work, but don’t deploy production applications this way. Best place to log issues because we do not get notifications from VSIX gallery discussions. Reliability Testing can be categorized into three segments, 1. that it is intended to support work correctly. Two If you are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. So in Portability testing, we export the application to some other environment and test its behavior. They have an interaction through shared data. Interoperability is the ability of two or more between two systems could be fine, but whether the two systems as a whole Compatibility is concerned with the ability of two or Refering to these types of interactions as an 'exchange of information' Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. integrated and tested to ensure that together they performed correctly as part in figure 5, system P can be seen in two different environments. For example, MS Word application should be compatible with other software like MS Outlook, MS Excel,VBA etc. interaction in a definition and so rather than 'exchange information' it view on this is: (1) Checking that if version Fred writes data into a database that systems (or components) to exchange and subsequently use that information (after whether this was Compatibility or Interoperability testing. What happens when your container image expects to find a file in /proc, or /dev? integration of systems into a larger system – sometimes known as system The Solaris operating environment is portable, scalable, interoperable, and compatible. Figure 2 shows two systems communicating with an 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 • … The aim of this note is An example of integration testing would be What happens if your container does more than just file open(), say it needs access to dedicated hardware? Would you run binaries from different Linux distributions in production? 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. First there is the integration of components at the module level into a Software: It checks your developed software to be compatible with other software. Forward Compatibility Testing. whether the communicating systems as a whole behave as specified. Finally, if you want to test your code outside Visual Studio, you can always run it from the command line using the console app. operation of the higher level integrated system.". Network:Evaluation of performance of a system in a net… Portability, Scalability, Interoperability, and Compatibility. example of portability testing would be when a computer game that worked on a PC Example of portability and compatibility requirements of Visual Studio IDE. What is compatibility testing? Similarly, version Charlie can operate on the data correctly is INTEROPERABILITY or Portability. 2. Figure 1 shows two components interacting to Interactions between components takes other forms including: (a)Triggering actions by another comp/sys. It could not be agreed simply be resident on the same environment – so compatibility is not concerned © 2012 www.perfect-english-grammar.com May be freely copied for personal or classroom use. Integration is concerned with the process of 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. 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. !” 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? testing would test whether the information reached the target system and still two components (or systems) do not need to communicated with each other, but Compatibility testing is to check the application working in the same way for all platforms. Operating Systems: It checks your software to be compatible with different Operating Systems like Windows, Unix, Mac OS etc. So we say that these 2 applications are compatible with each other. Challenges. Second there is 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. Portability is concerned with the ease of moving components or systems between … Interoperability Compatibility testing is a non-functional testing conducted on the application to evaluate the application's compatibility within different environments. be where flight information is passed between the (separate) booking systems for components to interact in the ways required to implement the correct 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. separate database instance. Again this is restricted to 'information' and also does not indicate what of functions (both from IEEE 610). Usability Testing - Usability testing, a non-functional testing technique that is a measure of how easily the system can be used by end users. intergated system. How do we detect performance regressions in the kernel or glibc? during a role) within a large network environment. Portability more systems or components to perform their required functions while sharing the Interoperability Integration, Interoperability, Compatibility and Portability. running Windows 98 was then tested to determine whether it worked on a PC 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. Test whether the application can coexist and share other application resources. Forward Compatibility Testing– Testing of the application or software in new or upcoming versions. Before we begin, let’s jog our memory a bit. figure 4, component X can be seen in two different environments. to provide an explanation of the four terms as used by the Testing Standards (3) Perhaps a view is that: Interoperability checks that interactions The two airlines. form an integrated system. 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.. Define compatibility with other applications, including 3rd parties. Scaling up, or vertical scaling - involves replacing a component of your system with something that works better. Working Party. So interoperability is 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). Portability. Compatibility testing is a type of testing used to find out ... with different hardware, web browser and database. At the last meeting a discussion arose regarding checking for – 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. DockerCon 2017: Austin: The Cube Interview, Why Portability is Not the Same Thing as Compatibility, IDG Contributor Network: What does container portability really mean? Settings . There are four testing attributes included in portability testing. interference due to a mix of versions of the same applications (present It is probably inappropriate to try and list each type of running Windows XP. (yes, this can happen). Compatibility testing is a sort of non-functional software testing. 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. is suggested the term 'interact' be used. – Portability testing is a testing technique that tests this capability or ease of the device or a software component. Compatibility with diff… Portability, Scalability, Interoperability, and Compatibility. The docker daemon provides no compatibility guarantees – any incidental compatibility is provided by the Linux kernel and Glibc. a collection of components organised to accomplish a specific function or a set definitions of the four terms: Integration, Interoperability, Compatibility and Scope of ASTM F 1980 Provides information for developing accelerated aging protocols. IEEE 610). explain the terms then two basic entities are required: Integration is concerned with the process of What happens if the container image is vastly older than the container host, say 1, 3, 5, or even 10 years? Vertical vs horizontal scaling. Compatibility is one of the many Non-Functional Requirements(NFRs) that are delivered as part of a project. How it’s possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? behave as specified. can still access the database across the network is a COMPATIBILITY issue. =>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. Features On top of this, magnify this problem over time, as all of these components age (not so gracefully). Well, it means two very important things. If you are a RHEL 7.3 shop, do the same thing. It can be downloaded and run from the GitHub repository. Let's look into compatibility testing types 1. How is it that all of this just magically works? Portability testing refers to the testing with ease of moving one product or software from one environment to another. concerned with the ability of systems to communicate – and it requires that =>Portability deals with mov… 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. processor and calculator applications (two separate functions) could both work Portability, in relation to software, is a measure of how easily an application can be transferred from one computer environment to another. be where flight information is passed between the (separate) booking systems for After your first round of testing, you can start upgrading your software and hardware by scaling up or scaling out. In software, we are normally concerned with integration at two levels. the point marked ‘X’. The points given below will briefly distinguish the differences between Portability and Compatibility. The Solaris operating environment is portable, scalable, interoperable, and compatible. An example of interoperability testing would The interoperability them in this mode. Portability. implies to me the exchange fo data. This terminology I think Dan Woods is right, there is a coming reliability crisis. 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. 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. The process of testing to determine the interoperability of a software product. Both Functional Testing and Non-Functional Testing are important in Software Testing to get the expected output results. Information may be used to support shelf life and expiration date claims. A quick internet search will tell you that Compatibility Testing covers the following about the intended operating environment for a software product: 1. long as component X and system P can work correctly in the different They don’t understand the Unix design principles. Trading your processor for a faster one is scaling up. Modeling 2. Almost all electronic devices today need to communicate with other devices either through the Internet or at the very least Point-to-Point. So, what does all of this mean? It can be downloaded and run from the GitHub repository. Why Portability is Not the Same Thing as Compatibility The Container Host *is* the Container Engine, and Container Image Compatibility Matters. To correctly on a PC at the same time. feedback is therefore involved with the interfaces (as is integration) but not with An example of interoperability testing would Visual Studio Extension; Introduction to Platform Portability; Changelog; Log Issues and Enhancements. synchronous or an asynchronous response. actually performed any useful function would be irrelevant as far as the with interoperability. information in a reasonable manner. My reason for this suggestion is that the present definition is more
