End-to-End Testing
We have adopted Cypress for end-to-end web application testing.
End-to-end testing (also known as system testing) is essential to the software development lifecycle, especially for web applications. End-to-end tests help ensure that all the application components work together as intended, from the front-end user interface to the server-side back-end functionality. In addition, end-to-end tests can help catch issues that may not be apparent in unit or integration tests by testing the entire application flow.
One of the primary benefits of end-to-end testing is that it helps improve the overall quality of the web application. By testing the entire application flow, developers can identify and fix issues early on before they become significant problems that impact the user experience. End-to-end tests can also help ensure that new features or changes to existing features do not introduce regressions that negatively affect the user experience.
End-to-end testing can also help reduce the risk of downtime or data loss. End-to-end tests can help prevent costly downtime and data loss by catching issues before they impact production environments. Additionally, end-to-end tests can help ensure that the application is working as expected after updates or changes to the infrastructure, such as deploying to a new server or upgrading to a recent version of a framework or library.
Overall, writing end-to-end tests for web applications is critical to ensuring the application’s quality and reliability. By testing the entire application flow, developers can catch issues early on and reduce the risk of downtime or data loss. Additionally, end-to-end tests can help improve the overall user experience by ensuring the application works as expected.
Usage
Adding Cypress to your Rails project
In order to not delay the decision to adopt Cypress, the automated Rails initialisation tooling will be added later. For now, please follow the cypress-rails instructions.
For information on using cypress, visit https://github.com/testdouble/cypress-rails#usage.
Adding Cypress to other projects
To add Cypress to non-Rails projects, please follow the official instructions on installing Cypress.
Writing tests
The Cypress documentation is excellent, but here are a few good starting points:
