-## Integration tests

-To run the unit tests, run `python integration_tests.py`. You can test just the output of the examples or just the memory usage of the tests by running
-`python integration_tests.py OutputTests` or `python integration_tests.py MemoryLeakTests` respectively.

+## Integration tests
+
+Integration tests are divided into three categories:
+
+* Compiler output tests: test that compiled Fur programs give expected output. Run with `python integration_tests.py CompilerOutputTests`.
+* Interpreter output tests: test that interpreted Fur programs give expected output. Run with `python integration_tests.py InterpreterOutputTests`.
+* Memory lead tests: test that compiled Fur programs don't leak memory (requires Valgrind). Run with `python integration_tests.py MemoryLeakTests`.
+
+Calling `python integration_tests.py` with no arguments runs all the integration tests.
