+# TODO(509038): Delete the file in LayoutTests/bluetooth after all the script
+# tests have been migrated to this directory.
+"""Generator script for Web Bluetooth LayoutTests.
+
+For each script-tests/X.js creates the following test files depending on the
+contents of X.js
+- getPrimaryService/X.https.window.js
+- getPrimaryServices/X.https.window.js
+- getPrimaryServices/X-with-uuid.https.window.js
+
+script-tests/X.js files should contain "CALLS([variation1 | variation2 | ...])"
+tokens that indicate what files to generate. Each variation in CALLS([...])
+should corresponds to a js function call and its arguments. Additionally a
+variation can end in [UUID] to indicate that the generated file's name should
+have the -with-uuid suffix.
+
+The PREVIOUS_CALL token will be replaced with the function that replaced CALLS.
+
+The FUNCTION_NAME token will be replaced with the name of the function that
+replaced CALLS.
+
+For example, for the following template file:
+
+// script-tests/example.js
+promise_test(() => {
+    return navigator.bluetooth.requestDevice(...)
+        .then(device => device.gatt.CALLS([
+            getPrimaryService('heart_rate')|
+            getPrimaryServices('heart_rate')[UUID]]))
+        .then(device => device.gatt.PREVIOUS_CALL);
+}, 'example test for FUNCTION_NAME');
+
+this script will generate:
+
+// getPrimaryService/example.https.window.js
+promise_test(() => {
+    return navigator.bluetooth.requestDevice(...)
+        .then(device => device.gatt.getPrimaryService('heart_rate'))
+        .then(device => device.gatt.getPrimaryService('heart_rate'));
+}, 'example test for getPrimaryService');
+
+// getPrimaryServices/example-with-uuid.https.window.js
+promise_test(() => {
+    return navigator.bluetooth.requestDevice(...)
+        .then(device => device.gatt.getPrimaryServices('heart_rate'))
+        .then(device => device.gatt.getPrimaryServices('heart_rate'));
+}, 'example test for getPrimaryServices');
+
+Run
+$ python //third_party/WebKit/LayoutTests/bluetooth/generate.py
+and commit the generated files.
