## Knowledge Captured
|
|
|
|
### From Our Implementation Experience
|
|
|
|
**✅ What Works:**
|
|
1. **Hybrid in-process testing**: Reliable, no process management issues
|
|
2. **Fixed port 9191**: Consistent, easy to debug
|
|
3. **Godog's exact patterns**: Eliminates undefined step warnings
|
|
4. **Real HTTP verification**: Proper black box testing
|
|
5. **Shared server pattern**: Fast execution for normal scenarios
|
|
|
|
**❌ What Doesn't Work:**
|
|
1. **External process management**: Unreliable, complex
|
|
2. **Dynamic port allocation**: Hard to debug
|
|
3. **Custom regex patterns**: Causes undefined warnings
|
|
4. **Mocked responses**: Defeats black box testing
|
|
5. **Assumed server state**: Leads to flaky tests
|
|
|
|
### Critical Insights
|
|
|
|
1. **Godog is Particular About Patterns**
|
|
- Must use EXACT regex from `godog --format=progress`
|
|
- Small deviations cause warnings even if tests pass
|
|
- Function names should match step descriptions
|
|
|
|
2. **Black Box Testing Requires Real Verification**
|
|
- `theServerIsRunning` must make real HTTP call
|
|
- No mocking - defeats the purpose
|
|
- Use actual server code for realism
|
|
|
|
3. **JSON Handling is Tricky**
|
|
- Feature files: `"{\\"key\\":\\"value\\"}"`
|
|
- Step implementation: `strings.Trim(arg, "\`)`
|
|
- Response validation: `strings.TrimSuffix(body, "\n")`
|
|
|
|
4. **Context Types Matter**
|
|
- Steps receive `*godog.ScenarioContext`
|
|
- Not `context.Context`
|
|
- Store context properly for step access
|
|
|
|
5. **In-Process Testing is More Reliable**
|
|
- Avoids external process complexity
|
|
- Uses real server code
|
|
- Fixed ports work better than dynamic
|
|
|
|
## Usage Examples
|
|
|
|
### Creating a New Feature
|
|
|
|
```bash
|
|
# 1. Create feature file from template
|
|
cp .vibe/skills/bdd_testing/assets/feature-template.feature features/my_feature.feature
|
|
|
|
# 2. Edit the feature file
|
|
# - Replace placeholders
|
|
# - Add scenarios
|
|
# - Use proper JSON escaping
|
|
|
|
# 3. Create step definitions from template
|
|
cp .vibe/skills/bdd_testing/assets/step-template.go pkg/bdd/steps/my_steps.go
|
|
|
|
# 4. Implement steps using Godog's exact patterns
|
|
# - Run: godog --format=progress
|
|
# - Copy exact patterns
|
|
# - Implement step functions
|
|
|
|
# 5. Register steps in InitializeScenario
|
|
# - Add to pkg/bdd/steps/steps.go
|
|
# - Use exact regex patterns
|
|
|
|
# 6. Run and debug
|
|
./vibe/skills/bdd_testing/scripts/debug-steps.sh
|
|
|
|
# 7. Validate
|
|
./vibe/skills/bdd_testing/scripts/run-bdd-tests.sh
|
|
```
|
|
|
|
### Debugging Issues
|
|
|
|
```bash
|
|
# Check step patterns
|
|
godog --format=progress --show-step-definitions
|
|
|
|
# Debug specific feature
|
|
./vibe/skills/bdd_testing/scripts/debug-steps.sh features/greet.feature
|
|
|
|
# Check server manually
|
|
curl -v http://localhost:9191/api/ready
|
|
|
|
# Run with verbose output
|
|
godog --format=pretty --verbose features/greet.feature
|
|
|
|
# Check common issues
|
|
cat .vibe/skills/bdd_testing/references/DEBUGGING.md
|
|
```
|
|
|
|
### Running Tests
|
|
|
|
```bash
|
|
# Run all BDD tests
|
|
go test ./features/... -v
|
|
|
|
# Validate no issues
|
|
./vibe/skills/bdd_testing/scripts/run-bdd-tests.sh
|
|
|
|
# Run specific feature
|
|
godog features/greet.feature
|
|
|
|
# Check test coverage
|
|
go test ./features/... -cover
|
|
```
|
|
|
