This lesson shows how hard it can be to find some complex bugs. It also mentions different activities which should be done by testers and why it is not possible to do everything because our time is always limited.
In this video you will learn about:
How in long sequence testing, even a small percentage of the vast number of possible tests can expose critical bugs. An example from a telephone system illustrates how a seemingly extreme case, repeating an action ten times without passing through a specific point, led to a real-world bug. Despite the belief that no one would conduct such a test, the bug occurred, causing a rotating outage. The narrative emphasizes the difficulty of anticipating all potential scenarios in testing and the challenges of making trade-offs among various testing tasks when facing an infinite set of testing possibilities.
Discussed terminology:
