<p class="purpose">Special sentences for requesting unit tests or providing test scripts.</p>
<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. </b>The verb "Test ... with ..." has two different uses, one public, letting
users set up test dialogues called "scenarios", and the other undocumented,
for performing unit tests of parts of the compiler. These exist because the
test suite for Inform is made up of end-to-end tests, and sometimes these make
it hard to see what any given component has done.

<p class="commentary">All sentences in the shape "test ... with ..." are accepted:
