The MSDN Web site also contains other important information about testing, such as white papers about exploratory testing and the method that independent testing organizations use to test the functionality of applications vendors submit for certification. NOTE: The testing suggestions in this section are not comprehensive and do not apply to all situations. They are provided to help you start thinking about how to test. Test installing and running your applications using the scenarios you plan to use during deployment.

For example, you might plan to deploy by installing on clean computers or by upgrading from Windows 95 or Windows 98 or an earlier version of Windows NT. If you plan to upgrade, you might keep the applications on the computer during the upgrade, or you might uninstall them and reinstall them after the upgrade. Because of differences between Windows 95 or Windows 98 and Windows , some application installations work differently depending on which operating system you use for the installation.

For example, if you install an application on a computer running Windows 95 or Windows 98, and then you upgrade the computer to Windows , the application might not work the same way as it would have if you had installed it in Windows In this case, you might need to uninstall the application and reinstall it after you upgrade or obtain a migration dynamic link library DLL.

A migration DLL allows an application that was originally installed on Windows 95 or Windows 98 to function correctly after the computer is upgraded to Windows Migration DLLs can resolve application problems by performing the following actions:.

Replacing or upgrading Windows specific or Windows specific files with Windows compatible files. Mapping Windows specific or Windows specific registry keys to the appropriate Windows locations. If your organization allows users to install applications, test the installation both as an administrator and as a power user; then test the application functionality.

Verify that an application can be installed by an administrator and uninstalled by a user. When logged on as user, the uninstall should be either complete or disallowed. Test applications using the features, configurations, and application suites you use to accomplish business tasks.

Access data on a server running the current version of Windows, as well as on a server running Windows Applications developed for previous versions of Windows might not take full advantage of new features, such as Active Directory or IntelliMirror. This section does not address these new features. Windows File Protection: Earlier versions of Windows allowed applications to replace shared system files during installation. When such changes occurred, users frequently encountered problems that ranged from program errors to an unstable operating system.

Windows File Protection is a new feature that prevents applications from replacing system files. This feature verifies that protected system files are the correct Microsoft version. If a file was replaced with an incorrect version, Windows restores the correct version. Robust heap checking: Windows includes several performance enhancements in the heap manager. Applications that did not use heap management correctly before might now have their memory management problems exposed.

Common problems include using memory after it has been freed and assuming that a memory does not move when it is reallocated to a smaller size. Enumeration of hardware devices: Changes in the list of supported hardware devices might cause problems for applications that use devices that are no longer supported. Enumeration of fonts: The list of fonts has changed. Because registry keys have been added to support internationalization, some applications might see multiple displays of fonts.

Changed registry keys: Some registry keys have been moved or deleted. Applications that write to the application programming interface API should not experience problems, but they can have problems if they write directly to the registry.

Version checking: Application installation programs that check versions incorrectly can have problems. Check for the version your application requires or later, unless your application is dependent on a specific operating system or version. Applications that use file filters, such as anti-virus programs, may lose significant functionality in Windows or later. When you encounter application compatibility problems, you need to prioritize them and then assign someone to resolve them.

You should have a plan for how to assign problems. Assigning the appropriate personnel to research and resolve problems is critical to the success of your application testing. Problem resolution might encompass a wide variety of activities, such as the following:. As you research the cause of a problem, consider various approaches to determine the most effective solution.

For example, you might choose to:. Always be sure that a problem does not occur on your current platform before researching it as a Windows compatibility issue. Some of the available resources for researching Windows compatibility issues are:.

Appendix E provides the specific location where can you obtain the specification. This guide include valuable information about diagnosing compatibility problems. Directory of Windows applications, which includes support information and links to vendor Web sites. Summary One of the primary tasks in preparing for testing is to write a test plan. More Information When you develop a test plan for testing application compatibility with Windows, include the following: Scope: What priority levels you address during testing?

Methodology: Who does the testing involve? Criteria for pass-fail: What determines if an application passes or fails? Schedule: How do you plan to complete the testing by the scheduled date? Establishing the Testing Scope If your organization uses many applications, you may not have time to test all of them as thoroughly as you would like. Defining the Testing Methodology When you plan the methodology, consider the following: Where will the testing take place?

Who will perform the tests? How will you communicate with and involve participants? It helps in testing multiple websites in browser and devices with instant result. It user real physical device for performing the testing. SpoonBrowser Sandbox is one of the most powerful compatibility testing tools. It supports Backward compatibility and supports almost all web and mobile browsers. SpoonBrowser Sandbox does not installed into your system rather we have to click Run to download the required browser from Microsoft and install in the Spoon account.

IE tab is very simple and light and one of the best tool available for free. Microsoft SuperPreview is another important tool used for compatibility testing. It allows multiple pages with multiple browsers together and also helps in rendering the web page in the different orientation — horizontal and vertically. Browsershots is the open source compatibility testing tool used for web testing.

It helps in taking the screenshot of the website for different browsers in different operating systems and thus helps the developers and testers to identify the website look and feel. Though it has one drawback, as it takes much time to display the result by taking screenshots. It is totally free. IETester is embedding multiple versions of Internet Explorer rendering engine into one single process.

Adobe Browser Lab is a service which helps in performing cross-browser testing by producing screenshots for the website for multiple browsers including Windows and OS X.
