+# CredentialManagement Testing
+
+## OTPCredential Testing
+
+In this test suite `otpcredential-helper.js` is a testing framework that enables
+engines to test OTPCredential by intercepting the connection between the browser
+and the underlying operating system and mock its behavior.
+
+Usage:
+
+1. Include `<script src="./support/otpcredential-helper.js"></script>` in your
+test
+2. Set expectations
+```
+await expect(receive).andReturn(() => {
+  // mock behavior
+})
+```
+3. Call `navigator.credentials.get({otp: {transport: ["sms"]}})`
+4. Verify results
+
+The mocking API is browser agnostic and is designed such that other engines
+could implement it too.
+
+Here are the symbols that are exposed to tests that need to be implemented
+per engine:
+
+- function receive(): the main/only function that can be mocked
+- function expect(): the main/only function that enables us to mock it
+- enum State {kSuccess, kTimeout}: allows you to mock success/failures
