matrix-is-tester is an integration testing system for Matrix Identity servers, similar to sytest (although using python rather than perl).
To launch the IS server, it attempts to import
matrix_is_test.launcher.MatrixIsTestLauncher. This must be provided separately
for the specific ID server implementation to be tested. See sydent's implementation
for an example of how this works.
Sydent supplies its matrix-is-tester launcher in the project directory, so to launch matrix_is_tester on sydent you would run:
PYTHONPATH="/path/to/sydent" trial matrix_is_tester
...which puts the launcher on the PYTHONPATH and invokes trial on matrix_is_tester (which is assumed to already be on sys.path).
