After I had been familiar with the React Native and Typescript that we use in the current project. Mr. Peter helped me with installing and configuring the environment and the project on the computer. And it took some time because there were so many dependencies involved in the beginning.
Following that, I needed to look into the project files specially the testing files and understand how that operates in order to carry on the testing later. Therefore, in order to begin learning how to test, you need to have an understanding of the concept of the AAA pattern. And That is how we structure a unit test by dividing each test into three sections — Arrange, Act, and Assert — with each section serving as a prerequisite for the next. The arrange phase puts up the input values for the test. The act phase initiates the primary tested function. And finally, the assert step ensures that the function’s output matches expectations.
After that, I got introduced to react testing library that we can implement a test using jets. Which is a test runner that identifies tests, executes them, and evaluates whether or not they passed or failed. I spent most of my time reading and gaining knowledge about testing, as well as putting several tests into practice.
