hegeltest_flutter 0.1.0

Flutter integration for hegeltest — property-based testing powered by Hegel's native engine. Use with flutter_test instead of package:test.

hegeltest_flutter — Property-based testing for Flutter

Flutter integration for hegeltest — property-based testing powered by Hegel's native fuzzing engine.

Why this package?

hegeltest depends on package:test. Flutter projects use flutter_test. This package bridges the gap by providing hegelFlutterTest() which uses flutter_test's test() function while giving you full access to all hegeltest generators.

Quick Start

dev_dependencies:
  hegeltest_flutter: ^0.1.0
  flutter_test:
    sdk: flutter

import 'package:flutter_test/flutter_test.dart';
import 'package:hegeltest_flutter/hegeltest_flutter.dart';

void main() {
  hegelFlutterTest('reverse is involutory', (tc) {
    final xs = tc.draw(lists(integers()));
    expect(xs.reversed.toList().reversed.toList(), equals(xs));
  });
}

Run with:

flutter test

API

hegelFlutterTest() accepts all the same parameters as hegelTest():

• testCases — number of random inputs to try (default: 100)
• seed — fixed seed for reproducibility
• reproduce — replay a specific failure blob
• config — HegelConfig for reusable settings
• setUpEach / tearDownEach — per-iteration lifecycle hooks
• All flutter_test parameters: timeout, tags, skip, retry

All generators from package:hegeltest are re-exported:

• Primitives: integers(), doubles(), booleans(), bigIntegers()
• Text: text(), fromRegex(), emails(), urls(), uuids()
• Collections: lists(), sets(), maps()
• Combinators: oneOf(), sampled(), nullable(), tuples2/3/4()
• Temporal: dates(), times(), dateTimes()
• Network: ipv4Addresses(), ipv6Addresses()
• Bytes: bytes()
