True

Verb

1. To make true; shape, adjust, place, etc., exactly or accurately: True the wheels of a bicycle after striking a pothole.
2. To make even, symmetrical, level, etc. (often followed by up): True up the sides of a door.
3. To test your Sass code; debug, perfect, etc. (often using True): True your sweet plugin before you deploy.

At this point True can only test values (e.g. function returns), not property/value output (e.g. mixin output).

    $base: (one: 1, two: 1, three: 1);
    $add: (one: 1, two: 2, three: -1);

    $test: map-add($base, $add);
    $expect: (one: 2, two: 3, three: 0);
    @include assert-equal($test, $expect,
      'Returns the sum of two numeric maps');
  }

  @include test('Is Equal [function]') {
    $test: is-equal(1, 1rem);
    @include assert-equal($test, false,
      'Returns false for equal numbers with different units.');

    $test: is-equal(1, 1);
    @include assert-equal($test, true,
      'Returns true for numbers that are truely equal.');
  }
}

@include report;

Settings

There is only one setting: $true-terminal-output toggles output to the terminal on and off.

• true will display a final summary of your test results in the terminal, and show detailed information on failing assertions. Required for true-cli.
• false to turn off all terminal output. Required for Libsass.
