# Unit Tests (Kotlin)

## Overview

Testes unitários para camadas **domain + application** com JUnit 5, MockK e gate JaCoCo **≥95% lines**.

## Guidelines

- Ler `references/unit-test-pattern-kt.md`.
- Usar `kotlin.test` + JUnit 5; coroutines com `runBlocking` ou `runTest`.
- Mockar repositórios com MockK — sem `@SpringBootTest` em unit tests.
- Configurar JaCoCo no `build.gradle.kts` do módulo.
- `./gradlew :packages:<module>:check` deve passar com coverage verification.

## Workflow

1. Identificar classes domain/application do BC.
2. Criar `*Test.kt` em `src/test/kotlin` espelhando o package.
3. VO/Entity: casos válidos e inválidos.
4. UseCase: mock repository, fluxo feliz + erros.
5. Adicionar/atualizar bloco JaCoCo no `build.gradle.kts`.
6. Executar `./gradlew test jacocoTestCoverageVerification`.
7. Ajustar testes até ≥95%.
