Testing with a real MongoDB database

Testing against an embedded MongoDB instance is quite handy. But there are times when we need to work with a real instance, and for multiple reasons: security settings, a batch of live data, a customized configuration. Whatever the reason, there is no need for that to derail our testing efforts.

We can write another test class, LiveImageRepositoryTests, and make it look like this:

    @RunWith(SpringRunner.class) 
    @DataMongoTest(excludeAutoConfiguration =

The details for this preceding live test are as follows:
