Being a diver since a few years I tend to take my own personal security quite seriously. Out-of-air at 20 m is not a pleasant experience, I´ve heard. One of the things I enjoy doing when diving is taking photos. This summer I bought a new underwater house for my compact and as I take security of my possessions seriously as well I decided to take the house for a test run without the camera, just to make sure it didn’t leak. Any diver more experienced than me can stop laughing now. Of course it all went wrong! No, it didn´t leak but instead of having a slightly negative buoyancy it instead was distinct positive making it hit me in my face, being in the way and all in all making the dive just a terrible experience.

So, what did I do wrong? I didn´t take the weight of the camera into account making the test, even if successful, a bad experience. Did my test succeed? Yes and no. The test as defined in my test case was successful but my confidence in the product became much lower.

When implementing security services you implement a safe guard that you need to trust. Whenever you need to test things first, make sure to include as much as possible so that confidence in the product is kept even during tests.
