## Writing Tests
-Have a look at test_batch_wordcount.sh for a very basic test and
-test_streaming_kafka010.sh for a more involved example. Whenever possible,
try
-to put new functionality in common.sh so that it can be reused by other
tests.
+### Examples
+Have a look at `test_batch_wordcount.sh` for a very basic test and
+`test_streaming_kafka010.sh` for a more involved example. Whenever
possible, try
+to put new functionality in `common.sh` so that it can be reused by other
tests.
+
+### Adding a test case
+In order to add a new test case you need a new line to either
`test-scripts/run-nightly-tests.sh` and / or
`test-scripts/run-pre-commit-tests.sh`
+
+Adding a new test case generally follows the following pattern
+
+```sh
+run_test "simple end-to-end test" "$END_TO_END_DIR/test-scripts/simple.sh
arg1 arg2"
