These modules use the --100 flag to run tests with 100%
coverage of all lines, branches, statements, and
functions.
Note that, as of tap v14, the default coverage level is 100% for lines,
branches, functions, and statements. As of tap v15, --check-coverage is
enabled by default. If you use node-tap, and your tests pass, you're in
this club by default ;)
