SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Tester drives test-driven development, generates tests for existing code, and reviews coverage quality. It helps teams write tests before implementing new behavior, generate tests for untested code, and assess whether tests actually verify the right things.

Core Features & Use Cases

  • Test-Driven Development (TDD): writes failing tests before implementation; follow Red-Green-Refactor cycles.
  • Generates tests for existing code: unit tests for public functions, edge cases, and regression tests.
  • Coverage analysis: reviews reports to identify untested paths and improve test quality.
  • Process guidance: describes the test pyramid and how to structure tests.

Quick Start

Activate in your test runtime and start by writing a failing spec, then have the tester generate tests and review coverage.

FAQPage Schema
How do I generate unit tests for existing untested code?

The tester generates unit tests and regression tests for existing code by analyzing public functions and edge cases. It creates specs that verify behavior and identifies untested paths to improve coverage quality.

What is the test-driven development Red-Green-Refactor process and how does it guide TDD discipline?

The Red-Green-Refactor TDD process involves writing failing tests first, implementing code to pass them, then refining. The tester enforces TDD discipline by generating initial failing specs and guiding each cycle phase.

Can I use this to add regression tests during bug fixes?

Yes, the tester generates regression tests during bug fixes to verify corrected behavior. It creates specs that confirm the specific defect is resolved and prevents future recurrence across code changes.

Does it work across different programming languages for test generation?

The tester works across software projects in multiple languages where unit tests are needed. It applies language-agnostic TDD principles to generate tests and review coverage reports regardless of runtime environment.

How do I review code coverage reports to identify untested paths?

The tester reviews coverage reports to identify untested execution paths and assesses whether tests verify correct behavior. It guides improvements to fill coverage gaps and strengthen overall test quality.

When should I follow the test pyramid structure for organizing tests?

Follow the test pyramid structure when organizing tests to balance unit and higher-level tests effectively. The tester provides process guidance on pyramid-aligned test structuring for optimal coverage and maintenance.
