Re: net.ltgt.gwt.maven and testing in multi-module project structure?

Maybe this is related to the issue described at https://lightrun.com/answers/gwtproject-gwt-28-rc2-all-gwttestcase-after-the-first-fails ?

No and no. I'm following the structure generated by net.ltgt.gwt.maven's 

mvn archetype:generate \

   -DarchetypeVersion=LATEST \

   -DarchetypeArtifactId=modular-webapp

That generates Maven's client, shared and server modules. shared is not a GWT module in that structure. At any rate, I changed the module name to have the package name set as a super package of both client and shared and the compilation goes through. 

Now, while it compiles, the client module tests fail with to instantiate any custom widgets that are *below* the module package 'com.effectiveem.app.gwt'. For example, 'com.effectiveem.app.gwt

.client'

[ERROR] testUpdateRowWithUnmodified(com.effectiveem.app.gwt.client.document.GapAnalysisItemListTableGWTTest)  Time elapsed: 0.032 s  <<< ERROR!

com.google.gwt.core.shared.SerializableThrowable: com.effectiveem.app.gwt.EemApp.JUnit:com.effectiveem.app.gwt.client.document.GapAnalysisItemListTableGWTTest.testUpdateRowWithUnmodified: could not instantiate the requested class

Caused by: com.google.gwt.core.shared.SerializableThrowable: (TypeError) : Cannot call method "new" of undefined

Obviously, I'm doing something wrong but I'm struggling to understand what.

Did you give the shared module a gwt.xml file? Did you inherit in the main project's gwt.xml the shared module's gwt.xml file?

Continuing the journey, in this multi-module client/shared/server structure, is it possible to have the shared code in a package different from the client? 

I get 

"No source code is available for type com.effectiveem.app.gwt.shared.GapAnalysisLineItemVO; did you forget to inherit a required module?
[ERROR] Hint: Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly"

The client sits in com.effectiveem.app.gwt.client.

Client's pom sets the module name to 

<moduleName>com.effectiveem.app.gwt.client.EemApp</moduleName>

Thank you, the setting the <include> did it.

FYI, using a GWTTestSuite can improve performance (that's why it's the default in the plugin, because it favors best practices): https://www.gwtproject.org/doc/latest/DevGuideTesting.html#DevGuideJUnitSuites

 

My next question about testing is, what are the expectations for the test module? Are we still required to provide a separate JUnit.gwt.xml?

You've never been (or at least not for many many years) as GWT will synthesize a module that inherits both com.google.gwt.junit.JUnit and the module your GWTTestCase's getModuleName() returns.

The gwt-maven-plugin itself has no specific expectations either, so https://www.gwtproject.org/doc/latest/DevGuideTesting.html should apply as-is (I haven't re-read it though, but that's the goal of the plugin, to be a "thin" wrapper that only wires things that are specific to Maven, e.g. src/main/java, computing the classpath from dependencies, etc.)
