Study Notes
Importance of Software Testing
- Different software types require specific testing methods (e.g., e-commerce sites vs. Android apps).
- Software that is 99% bug-free but does not meet user requirements is still considered unusable.
Engineering Role of Testing
- Systematic evaluation ensures quality, reliability, and performance.
- Verification checks compliance with design specifications, while validation ensures user needs are met.
- Detecting defects allows engineers to identify, fix, and resolve issues in the software.
Testing Methodologies
- Automated testing utilizes scripts/tools, while manual testing involves human testers.
- Test design requires creating test cases based on requirements.
Types of Testing
- Covers various aspects of functionality: unit, integration, system, performance, and acceptance testing.
Tester Responsibilities
- Testers analyze requirements to understand what needs testing and collaborate with stakeholders.
- They focus on identifying defects, ensuring functionality, and enhancing overall software quality.
Defect Categories
- Compatibility Defects: Software fails across different platforms (e.g., Chrome vs. Firefox).
- Interface Defects: Issues with system component interactions (e.g., API failures).
- Data Defects: Incorrect data processing resulting in errors or corruption.
- Boundary-Related Defects: Failures in handling input limits (e.g., crashing with excessive input).
- Logic Defects: Flawed algorithms resulting in incorrect computations.
- Configuration Defects: Software misconfigurations that prevent functionality.
Test Case Design
- Elements include test steps, expected results, actual results, postconditions, status, and priority.
- Black-Box Testing Techniques: Focus on functionality without internal code knowledge (e.g., equivalence partitioning, boundary value analysis).
- White-Box Testing Techniques: Involves internal code testing (e.g., statement coverage, branch coverage).
- Experience-Based Testing: Testers rely on experience and intuition to identify defects.
Importance of Test Case Design
- Well-crafted test cases ensure coverage of all functional and performance aspects.
- Early defect detection through effective design saves time and costs.
- Allows for repeatable tests in future cycles, especially regression testing.
Tools for Test Case Design
- TestRail, qTest, Zephyr, HP ALM/Quality Center.
Defect Repository
- Helps track and manage software defects efficiently.
- Testers log, categorize, and prioritize defects for timely resolution.
Limitations of Testing Approaches
- Lack of direction can hinder targeted testing.
- Random inputs complicate reproducibility of defects.
- May not provide as detailed insights as systematic testing.
Boundary Value Analysis (BVA)
- Focuses on testing extremes of input values to identify defects.
- BVA is useful in scenarios with defined input ranges (e.g., numeric limits).
- Example: Testing input values at the boundaries (0 and 100) and just outside the range (-1 and 101).
Example of BVA Test Cases
- Test cases validate expected behavior at boundary conditions.
- Ensure system response aligns with expectations for valid and invalid inputs.
