Cypress - Frequently Asked Questions
How do I get the native DOM reference of an element found using Cypress?
To obtain the native DOM reference of an element found using Cypress, you need to access the element within a `.then()` command. Cypress wraps elements in jQuery, so you can get the native element from there. “`javascript cy.get(‘button’).then(($el) => { const nativeElement = $el.get(0); // Use the nativeElement as needed }); “` This approach ensures you are working with the native DOM element.How do I do something different if an element doesn’t exist?
For conditional testing and control flow, such as handling cases where an element does not exist, you should refer to Cypress’s Conditional Testing Guide. This guide provides extensive details on how to handle such scenarios effectively.How can I make Cypress wait until something is visible in the DOM?
Cypress commands are designed to automatically retry and wait for their corresponding elements to exist before failing. You can also configure timeouts for commands if needed. Most Cypress commands have a default timeout of 4 seconds, but you can customize these timeouts globally or on a per-command basis. For example, if an element is not actionable, you can use the `{force: true}` option with action commands. Additionally, Cypress’s Core Concepts guide provides more information on how to handle waiting for elements in the DOM.Can I override environment variables or create configuration for different environments?
Yes, you can pass configuration to Cypress via environment variables, CLI arguments, JSON files, and other means. Cypress allows you to configure different environments using these methods. For more details, refer to the Environment Variables guide.How can I block traffic going to specific domains?
To block traffic to specific domains, such as blocking Google Analytics, you can use the `blockHosts` option in the Cypress configuration file. There is also a specific recipe for stubbing Google Analytics available in the Cypress documentation.How do I verify that calls to analytics like Google Analytics are being made correctly?
To verify calls to analytics services, you can stub their functions and then ensure they are being called as expected. Cypress provides a Stubbing Google Analytics Recipe that outlines the steps to achieve this.How do I test uploading a file?
Testing file uploads in Cypress can be done using the `.selectFile()` command. Here is an example: “`javascript cy.get(”).selectFile(‘cypress/fixtures/data.json’); “` This command is detailed in the Cypress documentation, along with other options depending on how your upload code is written.How do I check that an email was sent out?
To check if an email was sent, it is recommended to use a programmatic approach rather than checking through the UI. You can use third-party APIs or interact directly with your server. For local applications, you can use a temporary local test SMTP server. For third-party email services, you can use test email inboxes with API access. More details are available in the Cypress documentation on testing HTML emails.How do I wait for multiple requests to the same URL?
To wait for multiple requests to the same URL, you can set up an alias using `cy.intercept()` and then wait for the alias multiple times. Here is an example: “`javascript cy.intercept(‘/users*’).as(‘getUsers’); cy.wait(‘@getUsers’); // Wait for first GET to /users cy.get(‘#list>li’).should(‘have.length’, 10); cy.get(‘#load-more-btn’).click(); cy.wait(‘@getUsers’); // Wait for second GET to /users cy.get(‘#list>li’).should(‘have.length’, 20); “` This approach ensures you can track and wait for multiple matching requests.How do I preserve cookies / localStorage in between my tests?
By default, Cypress clears all cookies, local storage, and session storage before each test to prevent state from leaking. However, you can preserve session details across tests using the `cy.session()` command or by disabling `testIsolation` at the suite or e2e configuration level.How do I test elements inside an iframe?
Currently, Cypress does not fully support testing elements inside an iframe, but there is an open proposal to expand the APIs to support “switching into” an iframe and then back out of it. For now, you may need to use workarounds or wait for future updates.How can I modify or pass arguments used to launch the browser?
You can modify or pass arguments used to launch the browser using the `before:browser:launch` plugin event. This allows you to customize the browser launch process as needed.How can I run a single test or group of tests?
To run a single test or a group of tests, you can use the `.only` command on a test suite or specific test. Alternatively, you can run a single test file or group of tests by passing the `–spec` flag to `cypress run`. Cypress - Conclusion and Recommendation
