I'm having problems running tests in IntelliJ using Robolectric and it looks like jMockit might be a factor. My test itself has absolutely no jmockit and in fact the test is now just comparing two strings. I'm working with a large codebase that relies pretty heavily on jmockit, so I think there's an issue with the classpath having jmockit. (I saw something similar but not the same at can jmockit and robolectric coexist?)

Is there a way to work around this? Am I going to have to blow away all my jmockit tests?

The test code is:

@RunWith(RobolectricTestRunner.class)
public class DefaultAssetFormatterTest {

    @Test
    public void test_asset_formatter() {
        assertThat("12345", equalTo("Fsdafadsf"));
    }

}

This is what I see when I run the test in IntelliJ:

You are going to have to upgrade to JMockit 1.5 to avoid this problem.

It occurs because of JMockit's inability to work in the presence of Robolectric's AsmInstrumentingClassLoader. Version 1.5 of JMockit makes it more robust in environments with custom classloading.

  • Do you mean 1.4? I don't see a 1.5. – Calvin Oct 18 '13 at 14:57
  • Is the official release of 1.5 tomorrow like the change site says? I'm having issues building it myself; getting WithCaptureTest (among others) throwing _type parameters of T cannot be determined; no unique maximal instance exists for type variable T with upper bounds int,java.lang.Object_ with mvn install and I'm getting _ExpectationsUsingReturnTypeConversionTest.java:108: unclosed character literal_ using ant. – Calvin Oct 19 '13 at 17:57
