It includes black box tests, regression tests, and error output tests.
They are run as part of all.bash.

To run just these tests, execute:

	../bin/go test cmd/internal/testdir

To run just tests from specified files in this directory, execute:

	../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'

Standard library tests should be written as regular Go tests in the appropriate package.
