Cypress could not verify that this server is running

Explanation:

When Cypress encounters the error message “could not verify that this server is running,” it means that the server being tested is not accessible or not properly configured. This error typically occurs when Cypress tries to make a request to the server but receives an unexpected response or no response at all.

Possible Causes:

1. Server not started or not running
2. Server URL or port is incorrect
3. Firewall blocking the server
4. Network connectivity issues

Solutions:

• Ensure that the server is started and running before running Cypress tests.
• Double-check the server URL and port in your Cypress configuration or test code. Make sure they match the actual server setup.
• If you’re running the server locally, disable any firewalls or security software that might be blocking the connection.
• Verify that your network connection is stable and functional.

Example:

Here’s an example of how to handle this error in Cypress:

describe('Testing Server Connection', () => {
  it('Should successfully connect to the server', () => {
    cy.request('GET', 'http://localhost:3000') // Replace with your actual server URL and port
      .then((response) => {
        if (response.status !== 200) {
          throw new Error('Server connection failed');
        }
      });
  });
});
