Unit Test Design & Implementation

1. Design, develop, and execute comprehensive unit test cases and test suites for application
   components written in Java, ReactJS, and Python.
2. Utilize and maintain testing frameworks specific to each component:
   1. Java (Backend): Write unit tests using JUnit / TestNG and use Mockito / PowerMock
      for mocking complex dependencies and external service calls.
   2. Python (Backend/Scripts): Write unit tests using PyTest / unittest and employ
      mocking libraries like unittest.mock.
   3. ReactJS (Frontend): Write unit tests for functional and class components using Jest
      and React Testing Library (RTL) to focus on user-centric behavior.
3. Implement techniques like test doubles (Mocks, Stubs, Spies) to ensure tests are isolated,
   deterministic, and fast.
4. Collaborate with developers to achieve high code coverage metrics without sacrificing test quality.

Quality Assurance & Engineering Practices

1. Advocate for and help implement Test-Driven Development (TDD) and clean code practices
   (e.g., SOLID principles) within the development teams.
2. Participate in code reviews to ensure new features and bug fixes are accompanied by robust
   unit tests.
3. Integrate unit tests into the CI/CD pipeline (e.g., using Jenkins, GitLab CI, or GitHub Actions)
   to enable continuous testing on every code commit.
4. Contribute to the overall automation and testing strategy, focusing on shifting quality left in
   the Software Development Life Cycle (SDLC).
