Running on org.usvm.samples.mock.MockRandomExamples.randomAsParameter after updating JcTestExecutor in UtBot I get the following tests (we can't use USVM's JcTestExecutor, because it's in test source root and also it doesn't return UTest and UTestExecutionResult).

    /**
     * @utbot.classUnderTest {@link org.usvm.samples.mock.MockRandomExamples}
     * @utbot.methodUnderTest {@link org.usvm.samples.mock.MockRandomExamples#randomAsParameter(java.util.Random,int)}
     */
    @Test(expected = NullPointerException.class)
    public void testRandomAsParameterThrowsNPEWithCornerCase() throws Exception  {
        MockRandomExamples mockRandomExamples = ((MockRandomExamples) createInstance("org.usvm.samples.mock.MockRandomExamples"));
        
        mockRandomExamples.randomAsParameter(null, 0);
    }
    
    /**
     * @utbot.classUnderTest {@link org.usvm.samples.mock.MockRandomExamples}
     * @utbot.methodUnderTest {@link org.usvm.samples.mock.MockRandomExamples#randomAsParameter(java.util.Random,int)}
     */
    @Test(expected = NullPointerException.class)
    public void testRandomAsParameterThrowsNPEWithCornerCase1() throws Exception  {
        MockRandomExamples mockRandomExamples = ((MockRandomExamples) createInstance("org.usvm.samples.mock.MockRandomExamples"));
        Random randomMock = mock(Random.class);
        setField(randomMock, "java.util.Random", "nextNextGaussian", 0.0);
        
        mockRandomExamples.randomAsParameter(randomMock, 0);
    }

The following JcState:

And the following UTest with no mocked methods:

@IlyaMuravjov should be fixed now

[IlyaMuravjov]

@Saloed I am still getting same results on ilya_m/contest/mocks branch (update usvmVersion locally)

[Saloed]

Fixed

[IlyaMuravjov]

Now, two correct tests are generated for org.usvm.samples.mock.MockRandomExamples.randomAsParameter, although there's still unnecessary set field for nextNextGaussian.

    (when(randomMock.nextInt())).thenReturn(0);
    setField(randomMock, "java.util.Random", "nextNextGaussian", 0.0);
    
    int actual = mockRandomExamples.randomAsParameter(randomMock, 0);
    
    assertEquals(0, actual);
