What is Testing

Testing is crucial for the engineers and every engineering team. Testing helps in gaining the confidence on the features devs are developing, and shipping. Gone are the days where we used to relay only on the testers for the testing and bugs.

Now, engineers are encouraged to write test-cases to avoid bugs and errors. This will increase the confidence of the developers in the product and shipping the code with quality.
