Contact Form - Testing

Advanced React Sprint

Testing Web Applications

Objectives

explain what automated testing is and its importance
use react-testing-library for testing react components
use react-testing-library to test user interactions with fireEvent

Introduction

In this challenge, you will be writing tests for a contact form that has been built with React.

As a developer, you will be writing tests for every component. As we've learned, tests are a very important part of programming. The tests you will write will help you feel confident in the code you push to production!

Project Set Up

Create a forked copy of this project.
Add your team lead as collaborator on Github.
Clone your OWN version of the repository in your terminal
CD into the project base directory
Download project dependencies by running one of these two commands yarn or npm install
Using the same command tool (yarn or npm) start up the app using yarn start or npm start
Create a new branch: git checkout -b <firstName-lastName>.
Implement the project on your newly created <firstName-lastName> branch, committing changes regularly.
Push commits: git push origin <firstName-lastName>.

Test Runner

In a new terminal window, run yarn test or npm run test
With each saved change in your editor, the test runner will re-run all the tests
IMPORTANT If a test fails, use the test runner's error messages to find out why it is failing

Instructions and/or completion requirements (MVP)

In order to complete your mission for today, you will need to write tests to help you feel confident in shipping this component. Below is a general outline of how to accomplish this.

Take a good amount of time to use the form. Find out what behaviors you expect, and any you don't expect.
Write down on a peice of paper what you want to test. (This is a very important step - always plan before coding!)
Add your first test. This one should be a very simple test to make sure the testing setup is working.
Write a sufficient amount of tests to give you confidence in the project's code

If you come across any "unexpected" behaviors, try this flow:

Write a test that will pass for the "exptected" behavior
Confirm that the test fails, because of the "unexpected" behavior
Look at the code in the project to find what is causing the behavior
Fix the code so that your new test passes
Celebrate that your test helped you find and fix a bug!

Stretch goals

Using the REQ|RES API, build out a POST request in the form.
- Using the React Testing Library Docs, study how to test async calls
- Write a new test to cover your new async call
Add more elements to the form - eg dropdown, checkbox, etc
- Add tests to include the new form elements
