flutter_test_patterns 0.0.2

A helper package providing a toolbox of widget testing patterns.

Flutter Test Patterns

A toolbox of common, senior-level widget testing patterns for Flutter.

This package provides opt-in helpers to reduce boilerplate in your tests. It is NOT a testing framework. It does not impose a specific architecture or base class.

Philosophy

• Explicit is better than implicit. Helpers should not hide what they are doing.
• Composition over inheritance. No BaseTest classes.
• Isolation. State should not leak between tests or variants.

Patterns

Pattern	Purpose
Golden Variants	Generate multiple visual variants (primary, hover, disabled) in a single test block with deterministic output.
Interaction Contracts	Define and enforce reusable behavioral contracts (e.g., "tappable", "validates on blur").
State Matrix	Ensure a widget behaves correctly across all defined states (loading, error, data, empty).

Installation

dev_dependencies:
  flutter_test_patterns:
    path: . # Local path or git url

Quick Example (Golden Variants)

testWidgets('Button variants', (tester) async {
  await goldenVariants(
    tester,
    'button',
    variants: {
      'primary': () => Button.primary(),
      'disabled': () => Button.disabled(),
    },
  );
});

See doc/patterns/ for detailed guides on each pattern.
