Running Cypress Test Cases through Command Line

Cypress is a powerful automation tool that allows developers and QA engineers to Create and run test cases for web applications. While running test cases through the Cypress Test Runner is convenient, sometimes it is necessary to execute test cases directly from the command line. In this article, we will explore how to run Cypress test cases through the command line interface (CLI) and explore various options available.

1. Running Test Cases with Headless Browser

Cypress provides the option to run test cases in a headless browser, which means that the tests will be executed in the background without displaying the browser window. This can be useful when You want to run tests in a continuous integration (CI) environment or when you don't need to Interact with the user interface during test execution.

To run test cases with a headless browser, open the terminal and navigate to the project directory. Then, run the following command:

node_modules/.bin/cypress run

This command will execute all test cases in the project using the default headless browser (usually Electron). The test results will be displayed in the terminal window, showing the number of tests run, passed, and failed.

2. Running Test Cases with a Specific Browser

While running test cases with a headless browser is efficient, there may be situations where you need to test specific browsers for compatibility purposes. Cypress allows you to specify the browser in which you want to run your test cases.

To run test cases with a specific browser, open the terminal and navigate to the project directory. Then, run the following command:

node_modules/.bin/cypress run --browser <browser-name>

Replace <browser-name> with the name of the desired browser (e.g., Chrome, Firefox). This command will execute all test cases in the project using the specified browser. The test results will be displayed in the terminal window as before.

3. Running Test Cases for a Specific File

In complex projects, you may have multiple test case files, each containing a specific set of tests. In such cases, you may only want to run test cases from a specific file rather than running all test cases.

To run test cases for a specific file, open the terminal and navigate to the project directory. Then, run the following command:

node_modules/.bin/cypress run --spec <file-path>

Replace <file-path> with the relative path to the desired test case file. For example, if your test case file is located at cypress/integration/sample_spec.js, you would run the following command:

node_modules/.bin/cypress run --spec cypress/integration/sample_spec.js

This command will execute only the test cases from the specified file. The test results will be displayed in the terminal window.

Conclusion

In this article, we explored how to run Cypress test cases through the command line interface (CLI). We learned how to run test cases with a headless browser, how to specify a specific browser for test execution, and how to run test cases for a specific file. By leveraging the command line interface, we can automate the execution of test cases and integrate Cypress into our development process more seamlessly.
