Test Generator

This skill automates the creation of unit tests for NestJS components, ensuring a consistent testing pattern across the project.

Workflow

Identify the target file: Provide the path to the Service or Controller you want to test (e.g., src/modules/auth/auth.service.ts).
Execute the generator script: Use the bundled script to create the .spec.ts file.
Refine the test: The generated test will include a basic setup and "should be defined" test. You will need to add specific business logic tests.
Run the test: Use npm run test or npx jest path/to/file.spec.ts.

Usage

Run the following command from the project root:

node .gemini/skills/test-generator/scripts/generate_test.cjs <file-path>

Example

To create tests for AuthService:

node .gemini/skills/test-generator/scripts/generate_test.cjs src/modules/auth/auth.service.ts

This will:

Create src/modules/auth/auth.service.spec.ts.
Analyze the constructor of AuthService to identify dependencies.
Create mock providers for each dependency (e.g., UnitOfWork, MoodleService).
Scaffold a describe block with a beforeEach that sets up the Test.createTestingModule.

Standards Applied

File Naming: <original-name>.spec.ts.
Framework: Jest with @nestjs/testing.
Mocks: Uses jest.fn() or specialized mock objects for complex dependencies like UnitOfWork.

audit

CtrlAltElite-Devs/api.faculytics

Run a comprehensive code quality audit and automatically create GitHub issues for every finding. Produces one .md file per issue, creates the GitHub issues with labels, adds them to the project board, then writes an audit-summary.md. Trigger when user asks for a code audit, quality review, tech debt scan, security review, or anti-pattern analysis. Accepts an optional path argument to scope the audit (e.g. /audit src/modules/auth). Without args, audits the full src/ directory.
