There are others xUnit framework supported through others plugins that extends the xUnit plugin:
* CppUnit (CppUnit Plugin)
* Gallio (Gallio plugin)
* Parasoft C++Test tool(Cpptest Plugin)
* JSUnit (JSUnit Plugin)
* AUnit (Gnat Plugin)
Currently, there are plugins for each tool that doesn't provide JUnit test result report.
For instance, NUnit plugin, CppUnit plugin, Gallio plugin, MSTest plugin.
It's more suitable to have a generic plugin aggregating xUnit tools.
