Run angular end-to-end tests in watch mode

Question

Currently, I run ng e2e every time I make a change in my spec files and every time this command rebuilds the entire project ! is there a way to run the tests without rebuilding the entire project, just like ng test does it.

Answer 1

Just don't run ng e2e directly. It's very slow because it rebuild the whole project every time.

You can try npx protractor e2e/protractor.conf.js to run protractor directly.

the fastest workflow I've got was this npx protractor ... + vscode's rerun task keyboard shortcut. – Phip

Answer 2

Remove

devServerTarget 

from angular.json e2e section.

This way angular won't run ng serve when running the end to end. You will have to have them running in a separate terminal.

Protractor won't re-run on file change.

Answer 3

I believe you can do it yourself with a bit of set up by leveraging the powers of Gulp. Just came across this while watching some slides:
