Test tools developer Mercury Interactive Corp has launched the 5.0 version of their suite of programs WinRunner, LoadRunner and TestDirector. The Sunnyvale, California-based company, which carries out all its R&D in Israel, says the three products, which are also marketed together as TestSuite Enterprise, all offer added features in their current releases. WinRunner, for instance, has added both euro and Java testing, having already incorporated Y2K testing last year, in the 4.05 version. For e-commerce applications, meanwhile, it has added specific support for critical issues including digital certificates, HTTPS (HyperText Transfer Protocol Secure) and modem bandwidths. LoadRunner has been able, until now, to determine whether a program will work under a given workload and measure response times as that load increases. Now, however, it not only detects the level at which a program stops working, it also locates where the problem is. To do this, Mercury has added a transaction breakdown monitor, which enables users to see how much time a program is spending on each element. There is also a network delay monitor to determine the times spent between each IP address. Product marketing vice-president Zohar Gilad says that on the latest version of TestDirector, the company has taken the unprecedented step of opening the architecture for integration with other tools, not only from Mercury Interactive, but also from competing vendors, or even home-grown solutions that users have developed in-house.
