run_tests(+Spec)Run only the specified tests. Spec can be a list to run
multiple tests. A single specification is either the name of a test unit
or a term <Unit>:<Tests>, running only
the specified test. <Tests> is either the name of a
test or a list of names. Running particular tests is particularly useful
for tracing a test:5Unfortunately
the body of the test is called through meta-calling, so it cannot be
traced. The called user-code can be traced normally though.
