When running from the command line, I forgot to add all the items to the
class path. Once I did that, I got the same error IntelliJ did:
There was 1 error:
1)
testSimple(test.craig.MyTests)com.google.gwt.junit.JUnitFatalLaunchException:
The test class 'test.craig.MyTests' was not found in module
'test.craig.App'; no compilation unit for that type was seen
