You need to regularly test your reliability

Reliability testing isn’t a one-and-done thing. You need to test on a regular schedule to make sure your system is reliable in the face of changing systems.

Really to get value out of testing, you really need to do it regularly.

Of course, just like any other testing. Why do we do unit tests and integration tests on a regular automated basis? Well, it's because software changes and doing testing needs to be a repeatable process. Sometimes the system doesn't always behave the same way when given the same set of conditions. These things can be unpredictable.

So, running tests very regularly to create many opportunities to find sometimes rare failures is really what's needed. Running all of these tests manually is not something that scales across your organization. It's not sustainable to do.

That's exactly why we recommend running these things on a schedule and why we have features in Gremlin that allow you to schedule this test suite of common failures on a repetitive basis. So that you can run them every week, so that you create many opportunities to learn from failure.
