Go Integration Testing

Skill: go-integration-testing

Tests de integración en Go.

Cuándo usar este skill

• Al testear múltiples componentes juntos
• Al testear con dependencias externas
• Al validar flujos end-to-end

Build Tags

//go:build integration

package mypackage

func TestIntegration(t *testing.T) {
    // Tests que requieren recursos externos
}

# Solo unit tests
go test ./...

# Incluyendo integration tests
go test -tags=integration ./...

Test con Validator Completo

func TestFullValidation(t *testing.T) {
    if testing.Short() {
        t.Skip("skipping integration test")
    }

    v, err := validator.NewInitializedValidatorR4(ctx, opts)
    if err != nil {
        t.Fatal(err)
    }

    patient := loadFixture(t, "valid_patient.json")
    result, err := v.Validate(ctx, patient)

    if !result.Valid {
        t.Errorf("expected valid: %v", result.Errors)
    }
}

Golden Files

var update = flag.Bool("update", false, "update golden files")

func TestOutput(t *testing.T) {
    result := generateOutput()
    goldenPath := "testdata/golden/output.txt"

    if *update {
        os.WriteFile(goldenPath, []byte(result), 0644)
        return
    }

    expected, _ := os.ReadFile(goldenPath)
    if result != string(expected) {
        t.Errorf("mismatch")
    }
}
