Roboguice Not Working in JUnit Testing

Question

I am trying to write some tests with classes that use roboguice. Unfortunately it seems that guice is not injecting anything at all.

My setup is like so...

• I am using Intellij
• I have 2 intellij modules (1 for code, 1 for tests)
• I have 2 seperate module classes that extends AbstractModule(roboguice class) that define the bindings
• I have 2 roboguice.xml files that point to the package like this...

    <?xml version="1.0" encoding="utf-8"?>
         <resources>
             <string-array name="roboguice_modules">
                <item>com.evertaletest</item>
             </string-array>
         </resources>

Does this setup seems correct? Any class that is injected is null at the moment

Answer 1

I believe the <item> entry needs to give the name of your module class, not simply the package.

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string-array name="roboguice_modules">
    <item>com.evertaletest.YourModuleForCode</item>
  </string-array>
</resources>

But that will only be relevant for your production code. For tests, you will have to set your module in code instead of using XML.

In your test setup:

RoboGuice.setBaseApplicationInjector(application, 
    RoboGuice.DEFAULT_STAGE, new YourModuleForTest());
