[Res] Content Assertion not working through JunitRunner?

Hello,
Are there any known issue around content assertion not working when we run soapui project files through junit?
Here is my code

        SoapUIMockServiceRunner soapUIMockServiceRunner = new SoapUIMockServiceRunner();
        soapUIMockServiceRunner.setBlock(false);

        soapUIMockServiceRunner.setProjectFile(getClass().getClassLoader().getResource("project.xml").getPath());
        soapUIMockServiceRunner.run();
        SoapUITestCaseRunner runner = new SoapUITestCaseRunner();

        runner.setProjectFile(getClass().getClassLoader().getResource("project.xml").getPath());

        String testFilesDirectoryProperty = System.getProperty("testfilesdirectory");
        String[] properties = new String[4];

        properties[0] = "ENVIRONMENT=S1";
        properties[1] = "SERVER=server.com";
        properties[2] = "COMPONENT_PORTBASE=22480";
        properties[3] = "testfilesdir=" + testFilesDirectoryProperty;
        runner.setProjectProperties(properties);
        runner.run();

But i can't see content assertions being asserted when the tests are triggered?

Thanks
