Include a testing function that will also test if the service is null.

[ginere]

When using Spring, we need to verify that all the beans was been correctly inserted before verify that the service works. Something like :

    if (mailHandler == null) {
           log.fatal("Spring initializatin error, mailHandler:" + mailHandler
                  + "parameterDAO:" + parameterDAO);
        return false;
    }
    if (!test(mailHandler)) {
        log.fatal("Error testing the mail");
    }

It could be possible to made same function like:

    public static TestResult test(String systemToTestName,TestInterface serviceToTest);
