+# Utility script to run tests faster
+
+By default tests will be run using the Postgres container defined at the `docker-compose` file on the root of the repo,
+so prior to using this script make sure to launch the dev containers.
+
+You can use a different DB backend by defining `SUPERSET__SQLALCHEMY_DATABASE_URI` env var.
+
+## Use:
+
+From the superset repo root directory:
+
+- Example run a single test module:
+```$bash
+scripts/tests/run.sh tests.charts.api_tests
+```
+
+- Example run a single test:
+```$bash
+scripts/tests/run.sh tests.charts.api_tests:ChartApiTests.test_get_charts
+```
+
+- Example run a single test, without any init procedures. Init procedures include:
+  resetting test database, db upgrade, superset init, loading example data. If your tests
+  are idempotent, after the first run, subsequent runs are really fast
+```$bash
+scripts/tests/run.sh tests.charts.api_tests:ChartApiTests.test_get_charts --no-init
+```
+
+- Example for not recreating the test DB (will still run all the tests init procedures)
+```$bash
+scripts/tests/run.sh tests.charts.api_tests:ChartApiTests.test_get_charts --no-reset-db
+```
