What is the cause of a timeout error after passing Cypress test cases in GitHub actions with a local server (localhost:3000)?

edit

A timeout error after passing Cypress test cases in GitHub actions with a local server (localhost:3000) can have several causes:

1. The server is not running: If the server is not running, the Cypress tests will not be able to connect to it and will eventually time out.

2. The server is not listening on port 3000: Make sure the server is listening on the correct port (3000) and not on a different one.

3. The server is not accessible from the internet: If the server is running on your local machine, it may not be accessible from the internet, which will cause the tests to time out.

4. The tests take too long to complete: If the Cypress tests take too long to complete, they may exceed the maximum time limit set by GitHub actions, resulting in a timeout error.

5. Network latency: If the network connection between your machine and the server is slow or unreliable, the tests may time out.

To resolve this issue, you can try:

1. Ensure that the server is running and accessible from the internet.

2. Increase the timeout limit for the Cypress tests in GitHub actions.

3. Optimize the Cypress tests to make them run faster.

4. Check the network connection between your machine and the server and resolve any issues that may be causing slow network speeds.
