How to write Good Automated Tests

Writing good tests requires skill and consistency to effectively catch bugs and errors before they make their way into production.

Writing tests is one thing, but writing good tests is another. Good tests are those that thoroughly and accurately assess the functionality of the software, providing meaningful feedback to developers and helping them identify and fix issues.

Good tests typically fail when there are changes in system behavior, thereby providing negative feedback to indicate that something may not be working as expected.

So, how can you become proficient in writing good tests?

The answer is simple: practice and consistency. ✅

✨️ Keep tests simple and focused:
Avoid writing complex tests that try to cover multiple functionalities at once, as they can be difficult to maintain and debug.

✨️ Cover different scenarios and edge cases:
This means testing for different input values, error conditions, and boundary cases.

✨️ Keep tests fast and efficient:
Slow and resource-intensive tests that can slow down your testing process and impact productivity.

✨️ Regularly review and update tests: This means updating tests for changes in requirements, fixing broken tests, and removing redundant tests.

✨️ Test both positive and negative cases:
Don't just test for the expected positive cases, but also test for negative cases where the software should throw an error or fail gracefully.

I hope this inspires you to start writing good tests.
