unit-testing

unit-testing is a skill for OpenCode from cruzs85/opencode-multiagente-local-37-iterations. It costs 47 tokens per session (965 once invoked), scanned A, original, MIT.

A guide for creating, running, and troubleshooting unit tests in Angular 21 or newer. Unit tests check small pieces of code, such as services, components, pipes, and directives, in isolation.

In plain words
What is it for?
Use it to create tests for normal, edge, and error cases, run existing Jasmine or Jest tests, and investigate failures, including asynchronous code and Angular signals.
Why use it?
It helps verify that code behaves correctly and shows whether a failure comes from the test or the implementation. It also provides a consistent approach when tests are missing or already exist.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

unit-testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OBJETIVO

Garantizar la correcta verificación de la lógica del código mediante pruebas unitarias, manejando tres escenarios:

  • Crear tests cuando no existen
  • Ejecutar tests cuando ya existen
  • Diagnosticar fallos y determinar si son del test o de la implementación

REGLAS OBLIGATORIAS

1. Verificación de existencia

Antes de cualquier acción, verificar si el archivo .spec.ts existe:

find src/app -name "<nombre>.spec.ts" 2>/dev/null

2. Si NO existe → CREAR

Delegar a @code-writer la creación del archivo .spec.ts con:

  • Estructura: describe(), beforeEach() con TestBed.configureTestingModule, it() para cada caso
  • Cobertura mínima:
    • 1 caso feliz (happy path)
    • 1 caso borde (edge case)
    • 1 caso de error (si aplica)
  • Para servicios: Usar TestBed.inject() + inject() de Angular
  • Para componentes: Configurar TestBed con standalone: true, imports necesarios
  • Para signals: Verificar valores con signal() y set(), probar computed() y effect()
  • Estilo: Usar fakeAsync() y tick() para operaciones asíncronas
  • Ubicación: Mismo directorio que el archivo de producción

3. Si SÍ existe → EJECUTAR

npm test -- --testPathPattern=<nombre>.spec.ts

4. Si EJECUCIÓN FALLA → DIAGNOSTICAR

Reglas de diagnóstico:

Síntoma Causa Acción
Property 'X' does not exist on type 'Y' El test usa una API que cambió Fallo del test → modificar .spec.ts
Expected X to equal Y donde X es valor real incorrecto La implementación devuelve valor incorrecto Fallo de implementación → corregir producción
Cannot read property of undefined en el test Mock incompleto o datos mal formados Fallo del test → actualizar mocks
Timeout - Async callback Operación asíncrona no resuelta Fallo del test → ajustar fakeAsync/tick
Error de compilación TypeScript en el spec Firma de método desactualizada en test Fallo del test → actualizar firma

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

unit-testing is a skill published in the GitHub repository cruzs85/opencode-multiagente-local-37-iterations (5 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 965 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
