Cypress is a front-end testing tool that enables developers to write and run E2E tests for their web applications. It is a open source project and provides developers with an easy-to-use, yet powerful, testing framework. Cypress is used by companies such as Facebook, Google, Twitter, and Microsoft.
In this series of articles, we will introduce you to Cypress and show you how to use it to write and run E2E tests for your web application. We will also show you how to integrate Cypress with popular CI/CD tools such as Jenkins and Travis CI.
Part 1: Introduction
In this first article of the series, we will give you a brief introduction to Cypress and its features.
Cypress is a front-end testing tool that helps you write and run E2E tests for your web applications. It is open source and provides developers with an easy-to-use, yet powerful, testing framework. Cypress is used by companies such as Facebook, Google, Twitter, and Microsoft.
Some of the key features of Cypress are:
Cross-platform: Cypress runs on Windows, MacOS, and Linux.
Open source: Cypress is open source and free to use.
Easy to install: Cypress can be installed using a single command.
Real time reloads: Changes made to your tests are automatically reflected in the test runner UI. This helps you save time when writing and debugging your tests.
Time travel debugging: With Cypress’ time travel debugging feature, you can backwards and forwards in time to see how your application behaved at different points in time. This feature is extremely useful when trying to debug flaky tests or reproduce bugs.”
Fast test execution: Tests execute fast in parallelized mode on the same machine where they are being developed.” Interactive test runner UI: The test runner UI provides valuable information about each test step (e.g., network requests made, errors thrown) which helps you debug your tests easily.” Built-in mocking: Cypress comes with built-in mocking capabilities which makes it easy to mock network requests made by your application.” CI/CD Integration: Cypress can be easily integrated with popular CI/CD tools such as Jenkins and Travis CI.” spying & stubbing – Spies & Stubs allows us great flexibility while writing unit tests as we can control the behavior of functions without changing their implementation.” Assertions – Assertions help us verify the expected behavior of our system under test.” Continuous Testing – Continuous Testing ensures that our tests are always up-to-date with the latest code changes.” TestRunner – TestRunner is a command line tool that helps us run our tests on different browsers or devices.” Page Object Model – Page Object Model (POM) helps us organize our tests in a structured manner and makes them more maintainable.” Parallel Execution – Parallel Execution allows us to speed up our test suite execution by running multiple tests in parallel on different machines.”
