Interactive mode is a front end for scripted mode. There are two main screens, representing the summary and detail reports described elsewhere. Each is populated by calling testosterone in scripted mode in a child process, and then parsing and formatting the output. There are two additional screens: One is a primitive pager showing a Python traceback, which is used both for viewing individual test failures, as well as for error handling in both parent and child processes. The other is a primitive terminal for interacting with a Pdb session in a child process.
You can send a SIGINT (<ctrl>-C) at any time to exit
testosterone.
