group, setUp, and tearDown

Organize tests and share fixtures.

Tests Multiply Fast

One feature soon needs many tests. Without structure, a file becomes a flat, hard-to-scan list. Organization keeps it readable. 📚

A group bundles related tests under one label. Its output is indented, so suites read like an outline.

group('Cart', () {
  test('starts empty', () { /* ... */ });
});
