+Testing
+=======
+
+You can run the test suite much more quickly via "make -j test" (as
+compared to "make test"), at the expense of slightly more confusing
+output (interleaved parallel test output), and inaccurate intermediate
+success/failure counts, but the final counts displayed should be
+correct.
+
+Individual non-Python tests can be run via
+
+ ./wvtest run test/ext/TEST
+
+and if you'd like to see all of the test output, you can omit the
+wvtest run wrapper: `test/ext/TEST`. Individual Python tests can be
+run via
+
+ ./pytest test/int/test_something.py
+
+Internal tests that test bup's code directly are located in test/int,
+and external tests that test bup from the outside, typically by
+running the executable, are located in test/ext.
+
+
+Some aspects of the environment are automatically restored after each
+test via fixtures in conftest.py, including the state of the
+environment variables and the working directory; the latter is reset
+to the top of the source tree.
