A test helper for testing endpoints of APIs generated by Goa v3. This makes it possible to test endpoints using ikawaha/httpcheck.
- New checker.
- Set the method handler constructor, mounter, and method endpoint in the checker.
- Register the middleware with the checker's
Usemethod (If any). - Call checker's
Testmethod and test by ikawaha/httpcheck way.
