Organization uses a wide variety of OSs, browsers, software, hardware, databases, servers, clients, and hardware. System can operate with different versions, configurations, display resolutions, and Internet connection speeds and all these factors can impact the behavior of any product and introduce time killing, costly and embarrassing bugs. Noah specializes in test for compatibility using real test environments (not just virtual systems).

Noah offers Compatibility Testing to its clients and ensures compatibility of an application or Web site with different browsers, OSs, and hardware platforms. Noah offers all the hardware and software needed for compatibility testing including PCs, MACs, and UNIX workstations and servers; Windows 95/98/ME/2000/NT/XP, MacOS, and many varieties of UNIX; and versions of Netscape, Internet Explorer, and AOL.

We possess various Windows versions including: Win 95, Win 98, Win NT, Win ME, Win XP, Win 2000 and Windows Vista. We can configure each server or operating system with a variety of software products to test the application's interaction with other third-party or off-the-shelf software products. A list of browsers currently in use in our QA lab include: IE4, IE 4.5, IE5, IE5.5, IE6, NS4, NS4.5X, NS4.7X, NS6, NS6.1, NS6.22, NS7, AOL5, AOL6 and Mozilla.

Our compatibility testing process includes:

• Expert consultation for compatibility issues that are very significant in the execution of the application and a cost-effective matrix of platforms the application has to be tested against.
• Development of a Compatibility Test Plan
• Test execution by our staff of experienced test engineers.
