Canceling cypress run execution after cy.recordHar was called results in memory leak

[Rikkun-1]

Description
If you start recording har and then suddenly stop running tests with ctrl + c, this will leave a temporary har file in /tmp.

Expected behaviour
Even though the /tmp folder will be automatically cleared after a system reboot or you can do it manually, is there a way to automatically delete the temporary file on cypress run cancellation?

Thanks for your attention in advance. :)

@Rikkun-1, to automatically delete the temporary HAR files, you can consider using the disposeOfHar method.

This method is specifically designed to clean up and delete the temporary HAR file. By calling this method on the teardown, you can ensure that the temporary file is removed.

Here's an example of how you can use the disposeOfHar method:

// In your Cypress test file
beforeEach(() => {
  // Start recording HAR
  // ...
});

afterEach(function() {
  // Stop running tests
  // ...

  // Check if the Cypress run was canceled
  if (this.currentTest.state === 'failed') {
    // Delete the temporary HAR file
    cy.disposeOfHar();
  }
});

However, at this moment, there is no way to clean up such files on the unexpected cancellation, as Cypress does not yet support the graceful shutdown. I'm going to convert your report to the feature request if you don't mind.
