# Testing Strategy for deb-orchestrator
|
|
|
|
## Overview
|
|
|
|
This document outlines the comprehensive testing strategy for `deb-orchestrator`, covering unit tests, integration tests, performance tests, and quality assurance processes.
|
|
|
|
## Testing Philosophy
|
|
|
|
### **Incremental Testing**
|
|
- Tests are written alongside code development
|
|
- Each component has comprehensive unit tests before integration
|
|
- Integration tests validate component interactions
|
|
- Performance tests ensure scalability
|
|
|
|
### **Test-Driven Development**
|
|
- Write tests first when possible
|
|
- Use tests to validate design decisions
|
|
- Tests serve as living documentation
|
|
- Continuous integration ensures test coverage
|
|
|
|

|
|
|
|
## Best Practices
|

|
|
3. **Descriptive Names**: Clear test purpose
|
|
4. **Proper Setup/Teardown**: Clean test environment
|
|
|
|
### **Maintaining Tests**
|
|
1. **Update with Code**: Keep tests current
|
|
2. **Refactor Tests**: Improve test quality
|
|
3. **Remove Obsolete Tests**: Clean up unused tests
|
|
4. **Document Changes**: Update test documentation
|
|
|
|
### **Debugging Tests**
|
|
1. **Use Verbose Output**: `go test -v`
|
|
2. **Check Coverage**: Identify untested code
|
|
3. **Isolate Failures**: Run specific test functions
|
|
4. **Use Debug Logging**: Add temporary logging
|
