Introduction
The testing strategy for the Dev-Template project is designed to ensure stability and reliability across both the frontend and backend layers of the application. By utilizing modern testing frameworks and strictly defined configuration files, the project enforces a standardized approach to quality assurance. This strategy encompasses unit testing and integration testing to validate individual components and their interactions within the system architecture.
The scope of this strategy includes the configuration of test environments, the selection of testing libraries, and the execution of automated test suites. The primary goal is to provide developers with a robust feedback loop during the development lifecycle, facilitating the early detection of regressions and logic errors.
Frontend Testing Framework
The frontend testing infrastructure is built upon Vitest, a Vite-native testing framework. It is configured to handle TypeScript files and leverages browser-like environment simulations to test UI components effectively.
Core Configuration
The frontend uses a specific configuration file to manage the test runner's behavior, including environment setup and file transformations.
| Configuration Item | Value/Tool | Purpose |
|---|---|---|
| Test Runner | Vitest | Executes tests and provides assertions |
| Environment | jsdom | Simulates a web browser environment |
| Framework | React | UI library being tested |
| Coverage Provider | v8 | Measures code coverage metrics |

Testing Workflow
The frontend testing workflow integrates directly with the Vite build tool, ensuring that the development environment and testing environment share the same transformation logic.
The diagram above illustrates the path from test creation to execution within the Vitest ecosystem.

Backend Testing Framework
The backend testing strategy utilizes Jest, a comprehensive JavaScript testing framework. It is configured to work with the Node.js environment to validate API logic, data processing, and integration with external services.
Backend Test Scripts
The backend package.json defines several commands for executing tests in different modes, allowing for flexible development workflows.
test: Runs the standard Jest test suite.test:watch: Launches Jest in interactive watch mode for continuous feedback.test:cov: Generates a code coverage report using Jest's built-in coverage tool.
Sources: backend/package.json:8-10
Test Environment Lifecycle
The backend testing lifecycle ensures that the environment is properly initialized before any tests run and cleaned up after completion.
This sequence shows the interaction between the developer, the Jest runner, and the Node environment during execution.

Test Automation and Scripts
Both tiers of the application provide standardized npm scripts to automate the testing process. This allows for seamless integration into CI/CD pipelines.
Comparison of Testing Commands
| Tier | Action | Command |
|---|---|---|
| Frontend | Run Tests | npm run test |
| Frontend | UI Mode | npm run test:ui |
| Backend | Run Tests | npm test |
| Backend | Coverage | npm run test:cov |
Sources: frontend/package.json:15-18, backend/package.json:8-10
Conclusion
The testing strategy implemented in Dev-Template provides a bifurcated but unified approach to quality. By leveraging Vitest for the frontend and Jest for the backend, the project ensures that each environment is tested using tools optimized for its specific technical requirements. This structure supports scalable development by providing clear patterns for component and API validation.
