What is the exact feature or behavior required?
A command line argument to run all test suites registered to a project
One or more example use cases for the feature, including sample expected input and output.
Running all suites at once instead of one at a time from command line.
An explanation of why the feature is needed. This is important to prioritization. “It would be nice if...” takes a backseat to “This common scenario doesn’t work without...”.
It would be much more convenient to run three test suites with one command instead of three ,for example :)
