-- Test the output from a template by comparing it with fixed text.
-- The expected text must be in a single line, but can include
-- "\n" (two characters) to indicate that a newline is expected.
-- Tests are run (or created) by setting p.tests (string or table), or
-- by setting page=PAGE_TITLE (and optionally section=SECTION_TITLE),
-- then executing run_tests (or make_tests).
