Deprecated: this option is no longer used.

Main should be called within a TestMain function to allow subcommands to be run in the testscript context.

RunDir runs the tests in the given directory.

Deprecated: use [Main], as the only reason for returning exit codes was to collect full code coverage, which Go does automatically now: https://go.dev/blog/integration-test-coverage.

RunT is like Run but uses an interface type instead of the concrete *testing.T type to make it possible to use testscript functionality outside of go test.

Env holds the environment to use at the start of a test script invocation.

Params holds parameters for a call to Run.

A TestScript holds execution state for a single test script.

T holds all the methods of the *testing.T type that are used by testscript.

TestingM is implemented by *testing.M.

Deprecated: this type is unused.
