Conceptual Knowledge Assessment

Fundamentals of Software Testing​

Software testing is a crucial phase in the software development life cycle that ensures the quality and reliability of software products. Some key points to understand include:

  • Purpose of Testing: To identify defects, ensure functionality, and validate software against requirements.
  • Quality Assurance vs. Quality Control: QA focuses on processes to prevent defects, while QC involves identifying and fixing defects.
  • Verification and Validation: Verification ensures that the product is built according to specifications, while validation ensures it meets user requirements.

Testing Methodologies and Approaches​

Different testing methodologies and approaches guide the testing process. Familiarize yourself with the following concepts:

  • Waterfall Model: A linear approach where each phase must be completed before the next begins.
  • Agile Methodology: An iterative approach that emphasizes collaboration and flexibility.
  • DevOps: Integrates development and operations, focusing on continuous integration and delivery.

SDLC and Testing Phases​

Understanding the software development life cycle (SDLC) and its testing phases is crucial:

  • Requirements Phase: Analyzing requirements to create test cases.
  • Design Phase: Creating test plans and test scripts.
  • Development Phase: Performing unit tests.
  • Testing Phase: Conducting integration, system, and acceptance tests.
  • Deployment Phase: Ensuring the software works as intended in the live environment.

Importance of Early Testing​

Early testing is vital to identify and rectify defects sooner in the development process:

  • Bug Prevention: Detecting defects early reduces the cost of fixing them.
  • Continuous Feedback: Early testing provides feedback to developers, aiding in quality improvement.
  • Stakeholder Confidence: Effective testing from the beginning builds confidence in the final product.
