Testing Package Gap Analysis

Overview

This document analyzes the gaps between our Testing package's actual implementation and Laravel's testing functionality, identifying areas that need implementation or documentation updates.

Implementation Gaps

1. Missing Laravel Features

// Documented but not implemented:

// 1. Browser Testing
class BrowserTest {
  // Need to implement:
  Future<void> browse(Function(Browser) callback);
  Future<void> visit(String page);
  Future<void> click(String text);
  Future<void> type(String field, String value);
  Future<void> press(String button);
  Future<void> assertSee(String text);
  Future<void> assertPathIs(String path);
}

// 2. Parallel Testing
class ParallelTesting {
  // Need to implement:
  void setToken(String token);
  void setProcesses(int count);
  Future<void> runInParallel();
  Future<void> withoutOverlapping(String key);
  Future<void> isolateDatabase();
}

// 3. Time Testing
class TimeTesting {
  // Need to implement:
  void travel(Duration duration);
  void freeze(DateTime time);
  void resume();
  void setTestNow(DateTime time);
  DateTime now();
}

2. Missing Test Features

// Need to implement:

// 1. Test Data Factories
class TestDataFactory<T> {
  // Need to implement:
  T define(Map<String, dynamic> attributes);
  T make([Map<String, dynamic>? attributes]);
  Future<T> create([Map<String, dynamic>? attributes]);
  List<T> makeMany(int count, [Map<String, dynamic>? attributes]);
  Future<List<T>> createMany(int count, [Map<String, dynamic>? attributes]);
}

// 2. Test Doubles
class TestDoubles {
  // Need to implement:
  dynamic spy(dynamic target);
  dynamic mock(Type type);
  dynamic fake(Type type);
  dynamic partial(Type type);
  void verifyNever(Function invocation);
  void verifyOnce(Function invocation);
}

// 3. Test Database
class TestDatabase {
  // Need to implement:
  Future<void> beginTransaction();
  Future<void> rollback();
  Future<void> refresh();
  Future<void> seed(String class);
  Future<void> truncate(List<String> tables);
}

3. Missing Assertion Features

// Need to implement:

// 1. Collection Assertions
class CollectionAssertions {
  // Need to implement:
  void assertCount(int count);
  void assertEmpty();
  void assertContains(dynamic item);
  void assertDoesntContain(dynamic item);
  void assertHasKey(String key);
  void assertHasValue(dynamic value);
}

// 2. Response Assertions
class ResponseAssertions {
  // Need to implement:
  void assertViewIs(String name);
  void assertViewHas(String key, [dynamic value]);
  void assertViewMissing(String key);
  void assertSessionHas(String key, [dynamic value]);
  void assertSessionMissing(String key);
  void assertCookie(String name, [String? value]);
}

// 3. Exception Assertions
class ExceptionAssertions {
  // Need to implement:
  void assertThrows<T>(Function callback);
  void assertDoesntThrow(Function callback);
  void assertThrowsMessage(Type type, String message);
  void assertThrowsIf(bool condition, Function callback);
}

Documentation Gaps

1. Missing API Documentation

// Need to document:

/// Runs browser test.
/// 
/// Example:
/// ```dart
/// await browse((browser) async {
///   await browser.visit('/login');
///   await browser.type('email', 'user@example.com');
///   await browser.press('Login');
///   await browser.assertPathIs('/dashboard');
/// });
/// ```
Future<void> browse(Function(Browser) callback);

/// Creates test data factory.
///
/// Example:
/// ```dart
/// class UserFactory extends Factory<User> {
///   @override
///   User define() {
///     return User()
///       ..name = faker.person.name()
///       ..email = faker.internet.email();
///   }
/// }
/// ```
abstract class Factory<T>;

2. Missing Integration Examples

// Need examples for:

// 1. Parallel Testing
await test.parallel((runner) {
  runner.setProcesses(4);
  runner.isolateDatabase();
  await runner.run();
});

// 2. Time Testing
await test.freeze(DateTime(2024, 1, 1), () async {
  await processScheduledJobs();
  await test.travel(Duration(days: 1));
  await verifyJobsCompleted();
});

// 3. Test Doubles
var mock = test.mock(PaymentGateway);
when(mock.charge(any)).thenReturn(true);

await processPayment(mock);
verify(mock.charge(any)).called(1);

3. Missing Test Coverage

// Need tests for:

void main() {
  group('Browser Testing', () {
    test('interacts with browser', () async {
      await browse((browser) async {
        await browser.visit('/login');
        await browser.type('email', 'test@example.com');
        await browser.type('password', 'password');
        await browser.press('Login');
        
        await browser.assertPathIs('/dashboard');
        await browser.assertSee('Welcome');
      });
    });
  });
  
  group('Test Factories', () {
    test('creates test data', () async {
      var users = await UserFactory()
        .count(3)
        .create();
        
      expect(users, hasLength(3));
      expect(users.first.email, contains('@'));
    });
  });
}
