pub fn cargo_test_command<I, S>(args: I) -> CommandExpand description
Builds the cargo test invocation the runner wraps.
args is the runner’s own arguments with the program name already removed.
Cargo runs an external subcommand as cargo-test-better test-better ..., so
a leading test-better argument is dropped here and everything after it is
forwarded to cargo test verbatim. The structured-output channel is opened
by exporting RUNNER_ENV.
