+Test your changes
+-----------------
+
+For each contributions you make, you should test your changes as well.
+For this the Yocto Project offers several types of tests. Those tests cover
+different areas and it depends on your changes which are feasible. For example run:
+
+   -  For changes that affect the build environment:
+
+      -  ``bitbake-selftest``: for changes within BitBake
+
+      -  ``oe-selftest``: to test combinations of BitBake runs
+
+      -  ``oe-build-perf-test``: to test the performance of common build scenarios
+
+   -  For changes in a recipe:
+
+      - ``ptest``: run package specific tests, if they exist
+
+      - ``testimage``: build an image, boot it and run testcases on it
+
+      - If applicable, ensure also the ``native`` and ``nativesdk`` variants builds
+
+   -  For changes relating to the SDK:
+
+      - ``testsdk``: to build, install and run tests against a SDK
+
+      - ``testsdk_ext``: to build, install and run tests against an extended SDK
+
+Note that this list just gives suggestions and is not exhaustive. More details can
