Supports web and mobile applications, very scalable, very stable, and wonderful support

There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies.

Test Automation Architect at a tech vendor with 10,001+ employees

Integrated collaboration with automated test management has improved our agile workflows and continuously supports quality reporting

Visual Studio Test Professional could be improved as earlier we had flexibility in automation testing with TFS, which became a bit difficult moving to Azure DevOps. Additionally, in Visual Studio Code, we have an agent mode for GitHub Copilot, which is very helpful in testing or development phases, while Visual Studio's GitHub Copilot is a bit tricky and sometimes does not provide my desired output.For future improvements, I would like to see prompt fixing, as currently, if something goes wrong in Visual Studio, the fixing options are not always correct. If that intelligence is embedded, it would be very helpful.
