which is the best project for Software testing?

Question

1 in manual and 1 in automated testing.

Answer 1

You want a software that tests a software automatically.

Now it depends on the platform you developed application.

For unit testing Java applications,J2EE also, use JUnit(from sun microsystems, its free).

For testing .NET application, I don't think I need to tell you. With in the .NET platform you will find a debugger provided by the Microsoft.

For Black Box testing you can use, either WinRun or some software similar to this.

For testing C,C++ programs, I don't have much idea. Search google.

Ok.
