Description
I started using tumbletest in October last year to generate test cases for programming competitions. It's a very easy to use framework, that coupled with the "generator_utils" library is a very powerful tool for preparing ACM-style problems.
The workflow pattern random test-asserts-stringify is very productive and saved me a lot of time, also writing a checker for a more complex problem was never easier.
Two things that I have to mention though is the lack of generating methods for graphs (there are only nice features for generating random trees) and the possibility to set a timeout limit for a test-case in order to fail sources that take to long to give an output.
