  <!-- Target to check the test build, to see if it looks ok. We've had several cases where a change inadvertently and drastically changes
       the set of tests that are built, and that change is unnoticed. The most common case is for a build of the Priority 1 tests
       to only build the Priority 0 tests. This target is run after a test build to verify that the basic number of tests that were
       built is basically what was expected. When this was written, there were about 2500 Priority 0 tests and about 12270 Priority 1
       tests (differing slightly based on platform). We currently check that the number of Priority 0 tests is greater than 2000 and
       less than 3000, and the number of Priority 1 tests is greater than 11000.
