When developing automated tests using Cypress, you might often find yourself wanting to run just one test to quickly verify its behavior without having to wait for other tests to complete. This guide will walk you through various methods to achieve this, ensuring you can streamline your testing process effectively.
Running a Single Test File
If you want to run only one test file, you can use the following command:
cypress run --spec path/to/file.spec.jsYou can also use glob patterns to run multiple files matching a specific pattern:
cypress run --spec 'path/to/files/*.spec.js'Note: Make sure to wrap your glob patterns in single quotes to avoid shell expansion.
Running a Single Test in a File
Cypress provides a convenient way to run a single test within a file by using the .only method. You can apply it to it, describe, or context blocks:
it.only('only run this one', () => {
// test code here
});
it('not this one', () => {
// test code here
});Similarly, you can use describe.only to run all tests within a specific describe block:
describe.only('only this describe block', () => {
it('test 1', () => {
// test code here
});
it('test 2', () => {
// test code here
});
});Skipping Tests
Additionally, Cypress allows you to skip tests using the .skip method:
it.skip('skip this test', () => {
// test code here
});
describe.skip('skip this describe block', () => {
it('test 1', () => {
// test code here
});
it('test 2', () => {
// test code here
});
});Using Visual Studio Code Extension
For those who use Visual Studio Code, there is a handy extension called Test Utils that makes adding and removing .only and .skip easier with keyboard shortcuts. This extension supports JavaScript, CoffeeScript, and TypeScript.
Additional Methods
Another method to run specific tests without modifying the test files is by using the this.skip() function:
it('test page', function () {
// skip this test for now
this.skip();
cy.visit('http://example.com/');
cy.contains('test page').click();
cy.url().should('include', '/test-page/');
});Note: Ensure you use a regular function as the second argument of it, as this will not be available in arrow functions.
Conclusion
By leveraging these methods, you can significantly improve your Cypress testing workflow, allowing you to focus on individual tests without the overhead of running an entire test suite.
