NumRelative: Answer test results

This page exposes the results of running answer tests on STACK test cases. This page is automatically generated from the STACK unit tests and is designed to show question authors what answer tests actually do. This includes cases where answer tests currentl fail, which gives a negative expected mark. Comments and further test cases are very welcome.

 -1 ATNumRelativeTEST_FAILED-Empty TA.
The answer test failed to execute correctly: please alert your teacher. Attempted to execute an answer test with an empty teacher answer, probably a CAS validation problem when authoring the question.

 -1 ATNumerical_STACKERROR_tol.
The numerical tolerance for ATNumerical should be a floating point number, but is not. This is an internal error with the test. Please ask your teacher about this.
