I wanted to run my Angular (v21) tests in the browser (Edge), and followed the docs. For Edge to work, I had to install webdriverio.

My angular.json looked like this:

        "test": {
          "builder": "@angular/build:unit-test",
          "options": {
            "browsers": ["edge"]
          }

However, when I ran ng test I got the error message Browser "edge" is not supported by the browser provider "playwright". Supported browsers: firefox, webkit, chromium.
