Study Notes

Testing Techniques Overview

Defined in BS 7925-2, key black box test design techniques include equivalence partitioning, boundary value analysis, state transition testing, and cause-effect graphing.
Techniques can also be used as measurement methods to assess test effectiveness.

Equivalence Partitioning (EP)

EP divides inputs and outputs into partitions to reduce testing time.
Prioritization based on RISK informs which tests to execute first, focusing on critical items.
Effective prioritization ensures optimal testing results within limited time constraints.

Purpose of Testing Techniques

Techniques are procedures for selecting, designing, or conducting tests based on software models.
Aim to identify faults effectively, serving as best practices for generating quality test cases and measuring test efforts.
Testing should be rigorous, systematic, and thorough to enhance fault detection.

Advantages of Systematic Testing Techniques

Promotes diverse perspectives, leading to similar fault identification probabilities.
Enhances effectiveness by focusing on specific fault types and ensuring the right items are tested.
Increases efficiency by minimizing redundancy and leveraging measurable techniques for fault detection.

Types of Systematic Techniques

Static (Non-execution): Reviews documentation and source code without executing the program.
Functional (Black Box): Tests based on software behavior and functionality.
Structural (White Box): Tests derived from understanding the code structure and logic.

Testing Approach

Static: Includes reviews, inspections, and walkthroughs.
Dynamic: Involves behavior analysis through functional and non-functional testing.

Cyclomatic Complexity

Defined as a software metric for measuring the complexity of a program.
Examples demonstrate calculated cyclomatic complexity values for specific code scenarios, influencing the number of tests required for statement and branch coverage.

Testing Components

Functional Testing: Includes positive, alternative, and negative functional tests.
User Experience Testing (UX): Focuses on user interface and usability aspects.
Performance Testing: Evaluates application performance for single users.
Non-Functional Testing: Involves load, security, reliability, and interoperability testing, among other types.
