Similarly, we have another method called `afterEach` which simply performs some specified operations **after each** test.

Sometimes, we would want to execute some code only **once**, before any tests **in that scope** are executed. To achieve this, we can enclose the respective code into a `beforeAll` block, which follows the same syntax as a `beforeEach` block:

```js
beforeAll(() => {
    // before any tests are executed
});
```

Similarly, we can also specify some code to be executed after all the tests **in that scope** are executed by using a `afterAll` block:

```js
afterAll(() => {
    // after all the tests have been executed
});
```

Build on top of your previously acquired Manual Testing knowledge and learn Automation Testing using Node.JS and Jest. This course will also introduce you to some additonal libraries and tools like Selenium, Axios and Jenkins.

In this section, we will get an introduction to automation testing, both conceptually and practically. The application which we will be working on throughout this course will be briefly explored in order to familiarize ourselves with the work environment, and set the momentum for the rest of the course.

In this section, we will learn what Test Automation Frameworks are, why they are necessary, and how to use them. Most programming languages have Test Automation Frameworks, however, we will be using JavaScript to learn about one of the popular JavaScript Test Automation Framework known as Jest. Most of the concepts explored in this section will be transferable to other programming languages and frameworks.

In this section, we will learn how to perform more complicated tests in an automated manner, by automating the browser. This includes, automating user operations like visiting the website, inputting data into the fields and interacting with elements.

In this section, we will briefly explore some intermediate Automation Testing concepts like API testing using Jest and Axios, and setting up a CD/CI pipeline to streamline the whole testing process.
