+# Running Onionr tests
+
+Onionr has four types of tests:
+
+* unittests
+* integration tests
+* selenium tests (web tests)
+* runtime-tests
+
+
+## unittests
+
+Onionr uses Python's built in unittest module. These tests are located in tests/ (top level)
+
+Run all tests with `$ make test`, which will also run integration tests.
+
+Please note that one unittest tests if runtime-tests have passed recently. This is simply a forceful reminder to run those tests as well.
+
+You can also run a single unittest in a loop by using the script scripts/run-unit-test-by-name.py
+
+## integration tests
+
+These tests are pretty basic and test on stdout of Onionr commands.
+
+They are also run from `$ make test`
+
+The runtime-tests do most of the actual integration testing.
+
+## selenium tests
+
+These are browser automation tests to test if the UI is working as how it should for a user.
+
+There's only a couple and they're incomplete, so they can be ignored for now (test manually)
+
+## runtime-tests
+
+These are important. They look into the Onionr client Flask app when Onionr daemon is running and test a bunch of things.
+
+If you do it a lot you should make your own Onionr network (disable official bootstrap)
+
+You run this while the daemon is running (probably should make sure onboarding is done), with `$ onionr.sh runtime-test`
+
+It's necessary to do this before running `$ make test` for unittesting
