debugger-is-attached

What?

Lets you know if a debugger is actually attached

Why?

Sometimes I need to modify execution due to a debugger being attached. The most obvious use-case is for setting a longer test timeout when debugging a test.

There are other packages which do this!

Sort of. Some other attempts have been to observe the command-line parameters of the current process, which doesn't work when, eg, debugging a test in WebStorm. Also, debuggers can detach.

This solution is based on a GitHub comment so you know it's the real deal!

Usage

describe(`some fixture`, () => {
  beforeEach(async () => {
      const
        debugging = await debuggerIsAttached(),
        timeout = debugging ? 300000 : 5000;
      jest.setTimeout(timeout);
  });
  it(`should do the things`, async () => {
    // Arrange
    // Act
    // Assert
  });
})
