Replace tests/generator/*.xml with .js files

[AnmAtAnm]

Our generator tests currently try to read XML directly, but this doesn't work in a local file environment (browser security limitation), such as exactly the environment developers are likely to want to use when they are editing and testing the code base.

Thankfully, there is an easy fix. Since the test code is not distributed with other apps, we can use JavaScript ES6 raw strings:

var testdata = String.raw`
<xml xmlns="http://www.w3.org/1999/xhtml">
  <block type="unittest_main" x="33" y="140">
    <statement name="DO">
      <block type="procedures_callnoreturn">
        <mutation name="test repeat"></mutation>
        <next>
          <block type="procedures_callnoreturn">
            <mutation name="test repeat_ext"></mutation>
            <next>
              <block type="procedures_callnoreturn">
`

Raw strings can use any character except the backtick, and we don't have that in our test files.

$ grep \` tests/generators/*.xml
# No results
$

As .js files, we can import all the testdata via script tags. The only down side is that it is the file is no longer XML, but given that the XML does not need to be escaped, this is pretty trivial to cut and paste if you really need to use a syntax highlighting editor or other XML tool.

The page will need to update how it is reading the target test data in response to the selector.

@AnmAtAnm is this one still open ?

[AnmAtAnm]

I think so, but check with @rachel-fenichel.

[rachel-fenichel]

Yes.

We now run the generator tests in a browser and we plan to continue to do so, therefore we don't need to implement this.
