Test your frontend elements effectively
In this article, we will learn the following:
- What Cypress is and when to use it
- Basic testing in Cypress
- Advanced concepts in Cypress
- Interacting with user interface elements
- Best practices
Introduction
To test out your apps, you will have to perform the following steps:
- Start the app.
- Wait for the server to run.
- Perform the test by hand (click the buttons, type random text into a text box, or submit a form).
- Verify if the result of your test was correct (a change in title or a piece of text etc).
- Repeat these steps over again after simple code changes.
Repeating these steps over and over again becomes tedious and takes up too much of your time and energy. What if we could automate this testing process? Because of this, you could focus on more important stuff and not waste your time testing your UI over and over again.
This is where Cypress comes into play. When using Cypress, the only thing you have to do is the following:
- Code your test (Click the button, write text into a box).
- Start the server.
- Run or rerun the test.
That’s it! The Cypress library handles all of the testing for you. And the best part is, not only does it tell you whether all of your tests are successful or not, but it also informs you about which test failed.
Other than that, testing your code is great practice, so you have to learn a relevant framework later on. Cypress allows you to spin up tests in a matter of minutes.
Now that we have discussed its advantages, let’s learn about the fundamentals of this library.
Getting Started
Cypress installation & setup
First create a separate folder for your project and then initialize it:
