Eclipse RCP JUnit tests with SWT checks

The basing question:
How to do JUnit tests for RCP classes that create SWT GUI?

Vorgehen/Hinweise:

  • The „Run As“ dialog of Eclipse offers a „Run as Plugin“ option which must be used if OSGI features are used in the test.
  • If OSGI features are needed (e.g. an OSGI service is part of the game) than OSGI a BundleContext  has to be set up. Read OSGI Component Testing (Integration testing / “black-box-testing”) and perhaps OSGI BundleContext.java.
    If this is done, then a Bundle can be invoked/setup by FrameworkUtil.getBundle(AnyClassInTheTestPlugin.java)

Bundle Context

 

Setting up Eclipse like context for dependency injection:

If the class A has an annotation like

@Inject
C c;

Then a class A can be retrieved that has an object of C already injected like that:

IEclipseContext context = EclipseContextFactory.create("test context");
context.set(C.class, new C(...));
A a = ContextInjectionFactory.make(A.class, context);
