The code being tested

All of the code used in this example is located in the /chapter-09-node/testing-example folder. The code and corresponding tests are very simple and are not representative of real-world applications, but they're intended to demonstrate how to use Jest for testing. The following code represents the file structure of the /testing-example folder:

├── /src|    ├── /__tests__|    │    └── main.test.js|    └── main.c├── package.json└── package-lock.json

The contents of the C file that we'll test, /src/main.c, is shown as follows:

int addTwoNumbers(int leftValue, int rightValue) {    return leftValue + rightValue;}float divideTwoNumbers(float leftValue, float rightValue) {    return leftValue / rightValue;}double findFactorial(float value) { ...
