It looks like after override for custom use :

const { defineConfig } = require('cypress');

module.exports = defineConfig({
  e2e: {
    baseUrl: 'http://localhost:3000',
    viewportWidth: 1280,
    viewportHeight: 720,
    retries: {
      runMode: 2,
      openMode: 1,
    },
    setupNodeEvents(on, config) {
      // implement node event listeners here
    },
  },
});

Actual Test in cypress.config.js File in Cypress

Involving test performance in Cypress digital vendor front-end testing, by its nature, consists of creating real test scripts in JavaScript. The files that are stored under the scripts and the cypress.config.js file must have the specPattern field properly set and connected to a specific folder. The text provided a general idea of the scripts which I know you can modify because a spec is actually the name of a file again either in the same or not the same folder as the spec. This folder is the target for the test where the scripts are identified.

Example Test Script

Here is a very simple test script that illustrates a script:

describe("GeeksforGeeks Tests", () => {
  it("Visits the GeeksforGeeks homepage", () => {
    cy.visit("/tag");
    cy.contains("GeeksforGeeks");
  });
});

Output:

Disable Overriding Default Configurations

If you want to use the default configurations and not override them, simply set the properties you don’t want to override to their default values or omit them entirely from the config file.

Note: Make certain that the crucial settings are elaborated and approved by your team, so no unintentional configurations are ever made. You cannot really physically lock the settings or configurations, but you may opt to use the team’s consistent methods of working and code reviews, for this.

Conclusion

To customize your testing environment in Cypress, the cypress.config.js file must be configured. This environment provides the capacity to introduce various options like base URLs, viewport sizes, and retry strategies, thereby improving the efficiency and accuracy of your tests. The settings are important and should be understood and used properly for the testing framework to be tailored to the needs of your projects.

You can optimize the framework in such a way that it would be easily understood and executed if you learn the configuration settings of a particular tool. It is thus ensured that a project is not hindered by the testing configuration. People should also guarantee that their settings are all well-documented and that these are also reviewed by their fellow programmers so that the chances of the code for the tests that are not elicited.

Frequently Asked Questions on Configuration of cypress.config.js File in Cypress

How do I change the base URL for my tests?

You can need to alter the baseUrl property in the cypress.config.js file to change the base URL: baseUrl: ‘http://localhost:3000’

How can I set different viewports for different tests?

The direct way to make viewport settings different for individual test scripts is to override the settings through the use of Cypress commands: cy.viewport(1024, 768);

Is it possible to disable video recording?

Yes, videotaping is not the only option available. If you do not want to, you can just simply put the video property to false in the cypress.config.js file: video: false

What happened to cypress.json?

cypress.json has been replaced by cypress.config.js for greater flexibility and control.

Can I have multiple configuration files?

There is no feature of having multiple configuration files in Cypress as a typical way of doing things.
