AI Test Generation & TDD

Generate unit tests automatically, run TDD red-green-refactor cycles, and integrate AI testing into CI pipelines. GDPR-compliant.

🧪

Test Generation

`/test` generates tests for any file.

🔄

TDD Mode

`/tdd` for test-driven development cycles.

TDD Implement

Write code to pass failing tests.

Auto-Test

Run tests automatically after AI changes.

🤖

Test Agent

Dedicated test-generator agent with tools.

🔧

CI Integration

`lurus test` in CI pipelines.

Test Generation in Practice

Point the agent at any file and ask for tests. It reads the implementation, identifies all exported functions, detects existing test patterns, and generates complete test suites — including edge cases and mocks.

1Open a file or describe what to test
2AI reads the implementation and its dependencies
3Generates unit tests with edge cases and happy paths
4Creates necessary mocks and stubs
5Runs the tests and fixes any failures

TDD Workflow: Red → Green → Refactor

The AI follows the classic TDD cycle. Start with /tdd <feature> and the agent writes failing tests first, then the minimal implementation, then cleans up.

RED

Write Failing Tests

The agent writes tests that define the expected behavior. All tests fail because no implementation exists yet — this is correct.

GREEN

Minimal Implementation

Write the smallest possible code to make all tests pass. No over-engineering, no speculative features.

REFACTOR

Improve Quality

Clean up the code, remove duplication, improve names — without changing behavior. Tests keep you safe.

TDD Guard

Keep your team on track with TDD Guard. It monitors every code change and warns (or blocks) if production code is written without a corresponding test.

/tdd onWarn mode — alerts when code is written without a test
/tdd strictStrict mode — blocks code changes without corresponding tests
/tdd offDisable TDD Guard
/tdd-implementImplement code for existing failing tests

CI Integration

Combine test generation with code review in your CI pipeline for a full automated quality gate.

/testRun full test suite
lurus code-review-ciReview only changed files
--fail-on highFail build on high severity findings
--pr-commentsPost findings as inline PR comments

AI testing vs manual testing

AI test generation complements manual testing — it handles the repetitive work so you can focus on edge cases and business logic.

AspectAI Test GenerationManual Testing
Speed Seconds per file Minutes to hours
Consistency Same coverage every time Varies by developer
Edge cases Pattern-based detection Requires experience
Business logic Limited understanding Full context
Mocking Auto-generates mocks Manual setup
Maintenance Regenerate on changes Manual updates

Frequently asked questions

What testing frameworks does Lurus Code support?
Lurus Code generates tests for popular unit testing and E2E frameworks. It reads your project configuration to detect the existing test setup and matches your style.
Does AI-generated testing replace manual testing?
No. AI excels at generating unit tests, edge cases, and boilerplate. But tests for complex business logic, integration scenarios, and user acceptance still benefit from human judgment. Use AI for coverage, humans for critical paths.
How accurate are the generated tests?
AI-generated tests have a ~90% pass rate on first generation for well-structured code. The agent runs tests after generation and fixes failures automatically. Edge cases and mocks are included.
Can I use this for TDD in a team?
Yes. TDD Guard enforces test-first discipline across the team. In strict mode, it blocks code changes that lack corresponding tests — useful for maintaining test coverage on shared codebases.
Is my test code sent to external servers?
Lurus Code processes all data on EU servers. Your code is never stored after processing and never used for model training. A GDPR-compliant DPA is available.
