## Writing Tests
+As of November 2020, Flink has two broad types of end to end tests: Bash-based
end to end tests, located in the `test-scripts/` directory and Java-based end
to end tests, such as the `PrometheusReporterEndToEndITCase`. The community
recommends writing new tests as Java tests, as we are planning to deprecate the
bash-based tests in the long run.
