+Testing
+===
+
+# Integration testing
+
+Integration tests are test that are **not** run in CI, but rather manually by 
+the developers during development and review. 
+
+They are used in the following two cases:
+
+ * when a unit test is impactical or impossible 
+   for example, when a behaviour depends heavily on the hardware or SDL
+
+ * when you want to see something happening in a real game, but you cannot
+
+They are currently run both in native environments and in WASM.
+
+## Running the tests
+
+### Native
+
+```sh
+# Normal configure and build
+cmake -B build && cmake --build build 
+
+# Launch the test
+./build/test/NAME_OF_THE_TEST.test
+```
+
+### WASM
+
+```sh
+# Normal configure and build
+emcmake cmake -B build && emmake cmake --build build 
+
+# Launch the test
+emrun ./build/test/NAME_OF_THE_TEST.test.html
+```
