What you’ll learn
- What is Jest testing library and how to use it to write Unit and Integration test for any React Js application.
- How Software development and testing takes place in a real live project in any company
- What are Behavior driven development (BDD) and Test driven development(TDD) and the difference between the two techniques.
- We will also learn to create react app and functional components. Then write tests for these components.
- We will also see how to Mock real API calls for our integrating test.
- We will learn to create Backend Node Express API
- We will learn to make API calls from React app to our backend
- How to debug your test
In this course you will learn about jest testing library and how to use it to write Unit and Integration test for any react Js application.
We will start by learning how does software development and testing takes place in a real live project in any company.
Then we will learn about the importance of automation tests and importance of writing unit and integration tests.
We will then learn about Behavior driven development (BDD) and Test driven development(TDD) and the difference between the two techniques.
We will also learn to create react app and functional components. Then write tests for these components.
We will also see how to Mock real API calls for our integrating test.
All these and much more we will learn in handson based approach in a step by step manner.
