+# Testify
+
+This is a (very) old PHP unit testing framework. Like PHPUnit
+(at the time, anyway), it was a monolithic framework: it was
+an assertion library, a test runner, a test reporter, a mock
+object library and a coverage reporter (using xdebug).
+
+I wrote it because I didn't really like the complexity of
+PHPUnit. Also, the coverage generator in PHPUnit was incredibly
+slow, and so I took this opportunity to write something faster.
+For what it's worth, the coverage report generation was about
+100x faster than PHPUnit.
+
+It also generated pretty pie charts and stuff.
