There are a few files unit-tested with Go's testing package -- a few dozen cases total.

The vast majority of Miller tests, though -- thousands of cases -- are tested by running scripted invocations of mlr with various flags and inputs, comparing against expected output, and checking the exit code back to the shell.

Note: while this README.md file is within the test/ subdirectory, all paths in this file are written from the perspective of the user being cd'ed into the repository base directory, i.e. this directory's parent directory.

• mlr regtest --help

• go test -- TODO -- also comment

• mlr regtest -c ... runs the C version of Miller from the local checkout
