Create clickable links per failed test

[LarsDenBakker]

Terminal links can have line numbers to jump directly to a failed test line number. We need to see if we think this is useful, or if it creates too much spam.

This will require passing around test line numbers. We need to check if mocha has this information in the browser.

that actually already works 🎉

it's a chai feature and always worked 😅

Failed tests look like this

demo/test/pass-1.test.js
  test 2
    AssertionError: expected 1 to be a string
        at Context.<anonymous> (demo/test/pass-1.test.js:11:19)

you can click on demo/test/pass-1.test.js:11:19 and it will open the exact location which assertion failed 🤯

How could I have not known 😱 😱 😱 😱

ok we want to have it more obvious... something like this

demo/test/fail-object-diff.test.js
  object diff
    Go To Failed Assertion: demo/test/fail-object-diff.test.js:20:11
    Open Test in Browser: http://localhost/...
    expected { a: '1', b: '2', c: '3' } to equal { a: '1', b: '4', c: '3' }
    + expected - actual
     {
       "a": "1"
    -  "b": "2"
    +  "b": "4"
       "c": "3"
     }

I implemented an initial version of this, we can track improving it in https://github.com/LarsDenBakker/web-test-runner/issues/25
