Study Notes
Testing in the Development Process
- White-box Testing: Focuses on internal logic and structure rather than external behavior or user interfaces.
- Knowledge-Based Testing Techniques: White-box testing requires knowledge of internal workings, while black-box testing does not.
- Boundary Value Analysis: Technique that concentrates on testing the boundaries of input values.
- Path Testing: Ensures that every statement in the program is executed at least once through basis path testing.
- Black-box Testing Errors: Primarily targets interface errors and ignores internal code structure.
Software Testing Steps
- Verification and Validation: Key steps in the software testing process; deployment is not part of this process.
- Scaffolding in Unit Testing: Provides external support (drivers and stubs) for testing individual modules.
- Basis Path Testing: Guarantees each statement in the program is executed at least once.
Testing Approaches and Techniques
- Integration Testing Objective: Aims to test interfaces between components rather than the system as a whole.
- Functional Requirements in Black-box Testing: Focused on testing the program’s functional behavior without access to internal code.
- Unit Testing Purpose: Tests small, individual pieces of code independently to ensure they perform as expected.
- Regression Testing: Ensures that changes or new features do not break existing functionality in the software.
Types of Testing
- Usability Testing: Evaluates how easy and user-friendly the system is to operate.
- Recovery Testing: Assesses how well a system recovers from crashes or hardware failures.
- Load Testing: Checks if the software meets both functional and performance requirements under typical load conditions.
- Stress Testing: Tests the system's capacity to handle extreme conditions beyond normal operational load.
Characteristics of Various Testing Types
- Alpha Testing: Conducted by developers or quality engineers prior to external user testing.
- Equivalence Partitioning: Involves breaking inputs into groups where the expected behavior is the same.
- Big Bang Integration Testing: All modules are integrated and tested simultaneously at the end of the development cycle.
Key Testing Attributes
- Functional Testing Goal: Verifies software behavior against specifications; crucial for confirming that the system meets user requirements.
- Black-box Testing Feature: Concentrates on functional behavior rather than requiring knowledge of the internal code or logic.
Conclusion
- Focus on understanding the differences between testing methodologies, the objectives of various testing techniques, and the characteristics that define usability, recovery, load, and black-box testing for better assessment of software performance and reliability.
