Description
JOB DESCRIPTION :
Unit Test Design & Implementation
- Design, develop, and execute comprehensive unit test cases and test suites for application components written in Java, ReactJs, and Python.
- Utilize and maintain testing frameworks specific to each component :
- Java (Backend) : Write unit tests using JUnit / TestNG and use Mockito / PowerMock for mocking complex dependencies and external service calls.
- Python (Backend/Scripts) : Write unit tests using PyTest / unittest and employ mocking libraries like unittest.mock.
- ReactJs (Frontend) : Write unit tests for functional and class components using Jest and React Testing Library (RTL) to focus on user-centric behavior.
- Implement techniques like test doubles (Mocks, Stubs, Spies) to ensure tests are isolated, deterministic, and fast.
- Collaborate with developers to achieve high code coverage metrics without sacrificing test quality.
Quality Assurance & Engineering Practices
- Advocate for and help implement Test-Driven Development (TDD) and clean code practices.
- Participate in code reviews to ensure new features and bug fixes are accompanied by robust unit tests.
- 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.
- Contribute to the overall automation and testing strategy, focusing on shifting quality left in the Software Development Life Cycle (SDLC).
Qualifications
Strong Proficiency in Core Languages :
- Java : Solid understanding of OOP, data structures, and experience with Java-based unit testing.
- Python : Experience with Python for scripting and backend logic.
- JavaScript/TypeScript (for React) : Strong skills in modern JavaScript (ES6+).
Testing Framework Expertise
- Backend : JUnit/TestNG (Java), PyTest (Python), and mocking libraries like Mockito.
- Frontend : Jest and React Testing Library (RTL) is highly preferred.
Tools & Methodologies
- Experience with Git and modern version control systems.
- Familiarity with CI/CD tools (e.g., Jenkins, GitLab CI).
- Knowledge of an issue-tracking system like Jira.
- Understanding of code quality tools like SonarQube (or similar static analysis tools).
- Bachelor's degree in Computer Science, Software Engineering, or a related field.
- Minimum 3+ years of experience as an SDET, Automation Test Engineer, or a Software Engineer with a heavy focus on unit testing.
- Proven ability to write clean, maintainable, and effective test code.
