    You can use the popular API development and testing tool Postman to test CORS. It enables you to create HTTP requests and specify custom headers to test CORS configurations. Postman can also automatically generate preflight requests to test preflight request caching. Use Postman's scripting capabilities to automate test scenarios, too.
