Feature Request : add autograding for HTML activecode using JavaScript

[melissa-lynn]

We're working on edits to the webfundamentals book, and we would like to add autograding to the HTML activecode exercises. This would be done by writing the tests in JavaScript.

For a simple example, for the following exercise:

Create an h1 heading that says "Welcome!", and change the color to blue using the inline style.

this could be verified using tests something like:

assert.strictEqual(document.querySelector('h1').textContent, "Welcome!", "Checking contents of h1 element");
assert.strictEqual(document.querySelector('h1').style.color, "blue", "Checking inline color of h1 element");

So the problem to deal with is to report back how many tests passed.

Maybe developing a little test library for use with the HTML questions. I don't see assert.strictEqual as a standard Javascript function.

like what we did for Java we have a helper library. It could include various assertions as well as a report results method.

I think console.assert should be fine instead.

I can take a look at the Java helper library, but I don't know that I understand how activecode works and things fit together well enough to try to implement this myself.

I'll try to put together a quick prototype and see what you think. Maybe you can take it from there.

I don't think we would need to do anything on the PreTeXt side, if you wrote the suffix code and put the tests inside a <script>. I'll experiment.
