How It Works
Start generating unit tests with AI in 3 simple steps
Log in to your CodeGPT account
Set up your CodeGPT extension in Visual Studio Code and configure your preferred AI model for test generation.
Select the code you want to test in Visual Studio Code
Highlight any function, class, or module that needs unit test coverage.
Right-click and choose "CodeGPT: Unit Test CodeGPT" and run it
AI instantly generates comprehensive unit tests with edge cases, assertions, and proper test structure. Review, customize, and run your new test suite immediately.
Generative AI for Unit Testing: Real-World Examples
Automated Edge Case Detection
Our AI models identify potential edge cases in your code, generating tests to cover scenarios you might have missed—including null values, boundary conditions, and error states.
Test Suite Optimization
CodeGPT analyzes your existing tests and suggests improvements, ensuring comprehensive coverage with minimal redundancy. Eliminate duplicate tests and fill coverage gaps.
Rapid Test Generation for Legacy Code
Quickly create unit tests for legacy code bases, making it easier to maintain and refactor older projects. Add test coverage to untested code instantly.
What AI Can Test For You
🧪 Comprehensive Test Coverage
Generate tests for all code paths, including happy paths, error conditions, edge cases, and boundary values.
🎯 Edge Case Identification
AI automatically identifies and tests edge cases like null inputs, empty arrays, maximum values, and unusual data types.
🔄 Integration Test Generation
Create tests for component interactions, API calls, database operations, and service integrations.
🛡️ Error Handling Tests
Generate tests for exception handling, error states, validation failures, and recovery mechanisms.
📊 Mock & Stub Generation
AI creates appropriate mocks, stubs, and test doubles for dependencies and external services.
⚡ Performance Testing
Generate tests to verify code performance, timeout handling, and resource utilization.
Best AI for Unit Testing
Multi-Framework Support
Generate tests for Jest, Mocha, PyTest, JUnit, XUnit, and 50+ testing frameworks across all major languages.
Context-Aware Test Generation
AI understands your code architecture, dependencies, and existing test patterns to generate consistent tests.
Instant Test Generation
Generate complete test suites in seconds instead of spending hours writing tests manually.
Industry Best Practices
