Reality can be a harsh thing, and it happens more often than not that something we expected to work perfectly fine does not work when we actually want to use it. So throughout the history of computer programming, developers have thought about how they could make sure that the software works, and at best, actually work as expected.

In 1994, Kent Beck wrote the SUnit test framework for Smalltalk and kicked off the modern age of unit testing. The idea was quite simple: automate the evaluation of code and make sure it fulfilled a certain set of specifications. Even though there are many new frameworks today to achieve this, the basic idea is still the same: write code and check whether it produces the expected result.
