+# Testing
+
+This package utilizes the `integration_test` package to run its tests in a web browser.
+
+See [flutter.dev > Integration testing](https://flutter.dev/docs/testing/integration-tests) for more info.
+
+## Running the tests
+
+Make sure you have updated to the latest Flutter master.
+
+1. Check what version of Chrome is running on the machine you're running tests on.
+
+2. Download and install driver for that version from here:
+    * <https://chromedriver.chromium.org/downloads>
+
+3. Start the driver using `chromedriver --port=4444`
+
+4. Run tests: `flutter drive -d web-server --browser-name=chrome --driver=test_driver/integration_driver.dart --target=integration_test/TEST_NAME.dart`, or (in Linux):
+
+    * Single: `./run_test.sh integration_test/TEST_NAME.dart`
+    * All: `./run_test.sh`
