Re: Testing native @JsType in GWT tests

Thanks, Thomas. Changing to production mode fixed the problem.

However, I noticed that when using production mode in tests, I cannot test the type-matching for JSNI anymore. Previously, the GWT generated interface code caught the problem at runtime in development mode. When running in production mode, we will not see an exception. JavaScript's dynamic typing obscures this kind of problem.

public static native int badExample() /*-{ return "Not A Number"; }-*/;

I'd suggest you use -ea and -draftCompile for your tests (checkAssertions and draftCompile in the POM). Hopefully that would catch more of such bugs… (-draftCompile will also speed them up)
