Study Notes
Software Testing Overview
- Software quality assurance (SQA) controls the quality of software products through structured processes.
- Specialized testing teams carry out formal testing, typically at the end of the development phase.
- Testing is defined as executing a product to identify defects.
- Key attributes include:
- A formal process.
- Involvement of a specialized testing unit.
- Running programs on computers to evaluate performance.
- Adhering to approved testing procedures and test cases.
Evolution of Software Testing
- Evolved from simple program checks to comprehensive practices covering the software life-cycle.
- Five distinct levels of testing:
- Debug: Correcting identified failures.
- Demonstrate: Showcasing major features with standard inputs.
- Verify: Identifying as many faults in the Application Under Test (AUT) as possible.
- Validate: Identifying faults in requirements, design, and AUT.
- Prevent: Avoiding development errors through techniques such as "test before design."
Misconceptions About Testing
- Testing does not primarily aim to demonstrate the absence of errors.
- It does not merely show that a program correctly performs its intended functions.
- Establishing confidence in program functionality is a byproduct of thorough testing.
Importance of Testing
- Competent developers are not infallible; requirements may have unforeseen implications.
- System behavior may not be predictable from component specifications.
- Various programming languages, user interfaces, and operating systems can contain bugs that lead to failures.
- Trustworthiness of reusable classes and objects is essential for reliability.
Software Testing Life Cycle (STLC)
- Following basic principles enhances testing effectiveness:
- Specify expected outcomes for each test case.
- Developers should not conduct tests on their own programs.
- Thoroughly inspect all test results.
- Create test cases for invalid or unexpected production conditions.
- Test for unintended behaviors as well as intended functions.
- Avoid creating disposable test cases unless the program itself is disposable.
- Plan for the possibility of errors being present.
Test Automation
- Test automation involves creating software to facilitate testing processes.
- Automates manual testing, enhancing efficiency and reducing costs.
- Automated testing tools vary in their quality, methodology, and user-friendliness.
Manual Testing
- Primarily used for documentation, producing test guides, and measuring results.
- More time-consuming and costly compared to automated testing.
Early Software Testing Tools
- Mothora: Automated mutation testing tool-set for creating and executing test cases, measuring adequacy, and bug tracking.
- NuMega’s Bounds Checker & Rational’s Purify: Tools for runtime checking to prevent memory leaks and pointer issues.
- Ballista: Tool for robustness testing, providing quantitative assessments across different operating systems.
