Follow the same procedure as described for in the Synapse-Services-Repository project:Developer Best Practices
Use SafeHtml
Read this document on use of SafeHtml in GWT and adhere strictly to the contracts described. Apply true escaping methods to any user-generated value in the system.
Testing
See the general Synapse testing philosophy on the Synapse-Services-Repository Developer Best Practices page.
Specifics For GWT Testing
- Put all business logic into Presenters and make them JRE testable (aka JUnit).
- The philosophy of our infrastructure and this technique is described here
- This means that Presenters can not deal with class instances that rely upon GWT.create(...) calls. For the rare case when this is necessary, create a GWTTestCase. Be aware that these tests take significant time to spin up.
To mock callbacks, such as with RPC services, use AsyncMockStubber's static methods.
Code Block language java // Example call onSuccess(..) AsyncMockStubber.callSuccessWith("Result Object").when(mockService).getSomething(eq("someInputParam"), any(AsyncCallback.class)); // Example call onFailure(..) AsyncMockStubber.callFailureWith(new Throwable("error message")).when(mockService).getSomething(eq("someInputParam"), any(AsyncCallback.class));
