+# Continuous Integration
+
+## Testing
+
+MMTK core runs CI tests *before* a pull request is merged.
+
+MMTk core sets up two sets of tests, the *minimal tests* and the *extended tests*.
+* Minimal tests run unconditionally for every pull request and for every commit. This set of tests aims to finish within half an hour.
+  This include tests from the `mmtk-core` repo and integration tests from binding repos. Integration tests with a binding in the minimal tests should
+  focus on testing MMTk core features that is exclusively used for the binding.
+* Extended tests only run for a pull request if the pull request is tagged with the label `PR-extended-testing`. This set of tests
+  may take hours, and usually include integration tests with bindings which run the language implementation's standard test suite
+  as much as possible.
