flutter_test_gen 1.0.0

A CLI tool to automatically generate Flutter and Dart unit tests. Generates structured test templates for classes and functions to speed up Flutter testing.

Changelog

All notable changes to this project will be documented in this file.

1.0.0

🎉 Initial stable release

✨ Features

• Generate unit tests for Dart & Flutter code
• Supports classes, top-level functions, static & instance methods
• Automatically detects constructor dependencies and generates mocks
• Handles async methods and verification with mocktail
• Generates Arrange / Act / Assert structured tests
• Supports switch / sealed class test generation

🧪 Test Generation

• Groups tests by class and file
• Avoids duplicate test generation
• Supports:
  • Append mode (default)
  • Overwrite mode

0.1.3

• Fixed incorrect mock return generation in append mode (User() → User(name: 'test', age: 1))
• Fixed missing arguments in verify calls
• Fixed inconsistency between initial generation and append mode
• Reused TestBuilder for append (single source of truth)
• Improved model resolution using original sourceImports

0.1.2

• Corrected mock generation when regenerating tests in append mode.
• Fixed missing arguments in generated when() and verify() calls.
• Improved duplicate test detection to prevent duplicate tests/groups.
• Minor internal improvements and documentation updates.

0.1.1

Added

• Detection of sealed class pattern matching in switch expressions and statements
• Automatic generation of test cases for each detected switch pattern type
• SealedClassResolver to detect subclasses of sealed/base classes
• SwitchCaseInfo model to represent parsed switch pattern information
• Support for generating tests for sealed class error/state mappings
• Propagation of source file imports into generated test files

Improved

• Import resolution now prefers imports from the original source file
• Reduced incorrect or guessed imports when generating tests
• Improved handling of simple object parameters during test generation
• Cleaner test generation when switch-based logic is detected
• Improved generator stability when parsing complex method bodies

Fixed

• Incorrect import generation for classes referenced inside switch patterns
• Duplicate or conflicting imports when resolving types
• Missing imports for subclasses used in generated switch tests

Documentation

• Added documentation for:
  • SwitchCaseInfo
  • SealedClassResolver
  • collectImportsForType
  • additional model fields used by the generator

0.1.0

Added

• Constructor dependency detection and automatic mock generation
• Parameter dependency detection
• Automatic mock stubbing for dependency method calls
• Detection of property accesses and method invocations inside methods
• Support for async dependency stubs using thenAnswer
• Automatic generation of verify() calls for mocked dependencies
• Improved argument-aware mock generation

Improved

• Better test template generation
• Improved return type handling for generated mocks
• Automatic formatting of generated test files using dart_style
• Smarter detection of instance vs static methods
• Improved import resolution for generated tests

Fixed

• Duplicate mock stubbing for repeated property access
• Incorrect mock verification generation
• Invalid stub generation for dependency methods
