+# Test appletree on each PR.
+# We run three types of tests:
+#  - Pytest -> these are the "normal" tests and should be run for all
+#    python versions
+#  - Coveralls -> this is to see if we are covering all our lines of
+#    code with our tests. The results get uploaded to
+#    coveralls.io/github/XENONnT/appletree
+#  - pytest_no_database -> we want to make sure we can run the tests even
+#    if we don't have access to our database since this will e.g. happen
+#    when someone is pushing a PR from their own fork as we don't
+#    propagate our secrets there.
