• command (internal) - the command to run (set by first argument to t.spawn)
• args (internal) - arguments to subprocess (set by second argument to t.spawn)
• exitCode (internal) - Set on exit. The exit code of the process, or null if terminated with a signal.

t.spawn(cmd, [args], [options], [name]): PromiseWithSpawn

Arguments:

• cmd string - The command to run
• args (optional) string | string[] - Arguments to pass to the command.
• options (optional) SpawnOpts object

Spawns a process when the test starts, parsing its standard output as a TAP stream.

This is how the tap CLI runs test programs.

Returns a Promise that resolves when the test is complete. The subtest member on the Promise is a Spawn instance.
