Challenges With Integration Testing

Suppose that you are writing a MongoDB driver for java. To verify if all the implemented functionality works correctly, you ideally want to test it against a REAL MongoDB server. This brings a couple of challenges:
  • Mongo is not written in java, so we can not embed it easily in our java application
  • We need to install and configure MongoDB somewhere, and maintain the installation, or write scripts to set it up as part of our test run.
  • Every test we run against the mongo server, will change the state, and tests might influence each other. We want to isolate our tests as much as possible.
