Test and Analysis

Introduction

Ensuring code quality, performance, and reliability is a critical part of the development lifecycle. This section outlines the tools and strategies used in our project to test, analyze, and monitor the application at various levels.

We employ a combination of unit testing, end-to-end (E2E) testing, code quality analysis, and performance monitoring to ensure the application functions correctly and efficiently.

Unit Test Frameworks and Tools

  • Unit Testing is handled through frameworks such as Jest, allowing us to test individual functions and components in isolation.

Jest

  • Jest is used for unit testing JavaScript and TypeScript code. It provides fast test execution, built-in mocking, snapshot testing, and code coverage reports. Jest is integrated into our CI/CD pipeline to catch regressions early.

Unit Testing

End-to-End (E2E) Teststrategies

Cypress

  • Cypress is used for end-to-end (E2E) testing, simulating real user interactions to validate that the entire system behaves as expected.

End-to-End Testing

Static Code Analysis

  • Snyk is used to detect and manage security vulnerabilities in project dependencies. It integrates into the development and CI/CD process to continuously scan for known threats and suggest appropriate fixes.

SonarQube

  • SonarQube is integrated into our workflow to analyze code for quality, maintainability, bugs, and vulnerabilities.

Static Code Analysis

APM (Application Performance Monitoring)

  • We also assess the application's performance using Application Performance Monitoring (APM) tools and track benchmarks to identify and optimize slow or resource-intensive operations.

Performance and benchmarks

  • New relic is used to monitor application performance and run benchmarks. It provides detailed insights into response times, system throughput, and resource usage, helping us identify and resolve performance bottlenecks efficiently.
  • Note: New Relic is not active on the production environment. It is currently only integrated into the dedicated udviklingsmiljø branch for testing and performance analysis during development.
