How to Run Tests Across Multiple Environments with Cypress

Running automated tests across multiple environments is crucial for ensuring the consistency and reliability of your application under different conditions. Whether you're testing in development, staging, or production, Cypress provides a flexible and efficient way to manage environment-specific configurations. In this blog, we’ll explore how to run tests across multiple environments using Cypress and make your test suite more scalable and maintainable.

🚀 Why Test Across Multiple Environments?

Different environments often have distinct settings, data, and base URLs. By running your Cypress tests across all of them, you can:

• Detect environment-specific bugs early
• Validate deployments on staging before production
• Ensure consistent user experience everywhere

🔧 Step 1: Understand Cypress Environment Configuration

Cypress allows you to define environment variables that can be accessed during test execution. These variables can be set in several ways:

• cypress.json / cypress.config.js (project-wide config)
• Command line flags (temporary overrides)
• Custom config files for specific environments

🗂️ Step 2: Create Environment-Specific Config Files

To keep things organized, create separate config files for each environment.

For example:

arduino

cypress.config.dev.js

cypress.config.staging.js

cypress.config.prod.js

Each file might look like this:

js

// cypress.config.staging.js

const { defineConfig } = require('cypress')

module.exports = defineConfig({

  e2e: {

    baseUrl: 'https://staging.yourapp.com',

    env: {

      login_email: 'testuser@staging.com',

      login_password: 'stagingPass123'

    }

  }

})

Repeat similarly for dev and prod environments.

📦 Step 3: Use Environment Variables in Tests

You can access these variables inside your tests using:

js

const email = Cypress.env('login_email');

const password = Cypress.env('login_password');

cy.get('#email').type(email);

cy.get('#password').type(password);

cy.get('#loginBtn').click();

This allows the same test script to run across all environments with different inputs.

🖥️ Step 4: Run Tests with Specific Config

When running tests, you can specify the environment config using the CLI:

bash

npx cypress run --config-file cypress.config.dev.js

Or for staging:

bash

npx cypress run --config-file cypress.config.staging.js

This tells Cypress which environment setup to use, including the correct base URL and env variables.

🧪 Step 5: Optional – Use Environment Variables from the CLI

You can also inject env variables directly in the command line:

bash

npx cypress run --env login_email=test@prod.com,login_password=securePass --config baseUrl=https://yourapp.com

This is helpful in CI/CD pipelines where flexibility is needed.

✅ Best Practices

• Keep config files version-controlled to ensure consistency.
• Avoid hardcoding credentials or URLs directly in test files.
• Use beforeEach() hooks to reduce repetitive code in environment-dependent tests.
• Integrate with CI/CD tools like Jenkins, GitHub Actions, or GitLab CI for automated multi-environment testing.

📌 Conclusion

Testing across multiple environments using Cypress is not only possible—it’s simple and powerful. With flexible configuration options and environment variables, you can ensure your tests are robust and adaptable to changes in dev, staging, and production environments. By following these steps and best practices, you’ll be better equipped to catch bugs early, streamline your development process, and deliver more reliable software.
