Allow to filter long tests using a command line argument #2809
Description
Currently long running tests are enabled at compile time, it would be nicer to be able to select them at runtime with a command line argument for instance.
mytest --all # run all normal tests except the long tests
mytest --all --long # run all normal and long tests
mytest MyTestSuite # run all normal tests in MyTestSuite
mytest --long MyTestSuite # run all normal and long tests in MyTestSuite
