Question

When you issue ‘mvn gwt:test’, Maven creates a target/www-test -directory. This dir contains the actual tests being ran under another directory based on you package, e.g. target/www-test/com.mydomain.test.SomeApp.JUnit

I need to include a javascript file to this directory, or my tests will fail. How do I do this ? The documentation doesn’t seem to provide an option to include files here.

Answer 1

The subfolder name is actually based upon the module name your GWTTestCase returns from getModuleName(), with a JUnit suffix (GWT generates on-the-fly a module that inherits your module and the com.google.gwt.junit.JUnit module, among other things).

So, if you need some specific things for your test, you can very well create a test-specific module that inherits your “standard” module, and return that new module from getModuleName (GWT unit tests do that for testing some set-property or set-configuration-property values, or declare servlets for testing GWT-RPC, RequestFactory or FormPanel, for instance).

Now, if you only need a JS file, you can put it in your public path (i.e. by default, a public folder next to your gwt.xml module descriptor file). And you can use <script> in your gwt.xml to automatically pull that script inside the test page (because tests use a standard junit.html or junit-standard.html web page). If you really need to, you can override that HTML page by putting one with the same name in your public path, it should then override the one from the com.google.gwt.junit.JUnit module (you might have to explicitly inherit that module though, so its public path comes before yours)
