This is done to ensure that development is always according to the acceptance criteria and acceptance criteria are always according to the people who drive the business requirements.

Anyone who’s concerned with developing, delivering, and operating software knows the importance of making software and the systems it runs on observable. While classic logging is an essential tool in debugging issues, it often lacks context and only provides snapshot information of one specific location in your code/application.

Let’s look at the definition of quality to see how test automation isn’t quality assurance. One of the popular definitions of Quality is that it is “value” to someone “who” matters.

Assertions have been a foundational tool for writing understandable computer code since we could write computer code… far older than C’s assert() macro, they go back to at least John von Neumann and Herman Goldstine (1947) and Alan Turing (1949).

Sometimes code turns ugly. We add quick fixes or enhancements and our code starts to become a big tangle of functions that aren’t laid out in any sort of organized fashion. Over time, our code becomes bloated, difficult to maintain and what should be simple little fixes can quickly turn into long walks through messy syntax.
