using namespace sdl3cpp::testing;

class [StepName]StepTest : public WorkflowStepTest {
protected:

    void SetUp() override {
        WorkflowStepTest::SetUp();
        step = std::make_shared<sdl3cpp::services::impl::Workflow[StepName]Step>(logger);
    }
};

TEST_F([StepName]StepTest, GetPluginId) {
    EXPECT_EQ(step->GetPluginId(), "[plugin.id]");

ARCHITECTURE & DESIGN
================================================================================

Framework: Google Test (gtest)
Base Class: WorkflowStepTest (test_framework.hpp)
Dependency Injection: MockLogger via test framework
Test DSL: WorkflowStepBuilder for step definition
Context: WorkflowContext for state management

Design Principles:
  • Atomic test units (one step = one test file)
  • Single Responsibility (tests one functionality)
  • Deterministic (no randomness, reproducible)
  • Isolated (no cross-test dependencies)
  • Fast (parallel-safe, quick execution)

Mock Components:
  • MockLogger - All ILogger methods implemented
  • WorkflowContext - Key/value storage with type safety
  • WorkflowStepBuilder - Fluent interface for test setup

Per CLAUDE.md Alignment:
  ✓ Code = Doc principle (tests self-document)
  ✓ Atomic workflow steps (single responsibility)
  ✓ JSON-first configuration (tests use builder DSL)
  ✓ Multi-tenant by default (not applicable for unit tests)
  ✓ Mock-based testing (no real services)
  ✓ Comprehensive error handling
  ✓ Edge case boundary testing
  ✓ State management validation
