|
* - OAuthSecurityTest::testPkceRequirementEnforcement (integration test)
|
|
* - PkceAuthorizationCodeGrantHandlerTest (16 unit tests, 49 assertions)
|
|
*
|

* These tests originally attempted to go through the full /oauth/v2/authorize flow,
|
|
* but this caused hanging due to complex session/authentication handling in the test environment.
|
|
* Instead, we now test the security properties directly at the token endpoint level,
|
|
* which is where PKCE validation and other security checks actually occur in the OAuth flow.
