Testing Java full stack applications involves verifying both frontend and backend components. Here's a concise overview of essential tools used across the stack:

1. Unit Testing (Backend)

  • JUnit: Primary framework for unit testing Java code.

  • Mockito: For mocking dependencies in unit tests.

  • AssertJ / Hamcrest: Provides fluent assertions to enhance JUnit tests.

2. Integration Testing

  • Spring Test / Spring Boot Test: Integrated with Spring for testing application context, REST APIs, and data access layers.

  • Testcontainers: Spins up lightweight containers (like databases or Kafka) for realistic integration tests.

3. API Testing

  • RestAssured: Simplifies testing REST APIs in Java.

  • Postman: GUI-based API test tool, useful for manual and automated API testing.

  • Karate DSL: A BDD-style API testing framework for automated end-to-end tests.

4. Frontend Testing

  • Jest: For unit testing JavaScript (React, Angular).

  • React Testing Library / Enzyme: Used with React for DOM testing.

  • Karma + Jasmine: Common in Angular apps.

5. End-to-End (E2E) Testing

  • Selenium / WebDriver: Automates browser actions for full-stack user flow testing.

  • Cypress: Modern E2E test tool with great frontend testing capabilities.

  • Playwright: Fast, reliable E2E testing across browsers.

6. Performance Testing

  • JMeter: Load and performance testing for APIs and web apps.

  • Gatling: Scala-based tool for high-performance test scripting.

7. CI/CD Integration

  • JUnit XML Reports, Allure, or ExtentReports for integrating test results into pipelines.

Using a combination of these tools ensures robust coverage across the Java full stack.
