How should the test interface be configured?

[mdibaiee]

Currently we don't have any options, no configuration, but we will need such thing as we go further.

As @sindresorhus said in this comment we can read CLI arguments using process.argv, but there should be a real API for configuring test interface, like this:

var test = require('ava');
test.config({ fullTrace: true });

If we have this, we can extend the config with CLI arguments. Individual tests' configurations should override CLI arguments.

@sindresorhus Please label as question.

I don't think there should be. The public interface should be as simple and config-less a possible.

The flags are something we will handle internally, not in the public API. It will be passed to the Runner which will handle the changes, like making everything serial for the --debug flag.

@sindresorhus Then how should we check for flags inside test interface? Probably a helper function like this?

function hasFlag(key) {
  return process.argv.indexOf(`--${key}`) > -1 || process.argv.indexOf(`-${key}`) > -1;
}

[sindresorhus]

Yes, we can use something like has-flag.
