Study Notes

Benefits of Testing

Increased test effectiveness and efficiency by implementing process improvements
Improved quality of testware through joint reviews of test processes
Team bonding and learning through raising issues and proposing improvements
Improved quality of the test basis by addressing deficiencies in requirements
Better cooperation between development and testing through regular collaboration reviews

Test Levels and Test Types

Test levels are groups of test activities performed at different stages of software development
Test levels are related to other activities within the SDLC
In sequential SDLC models, test levels are defined such that the exit criteria of one level are part of the entry criteria for the next level
Test types are groups of test activities related to specific quality characteristics and can be performed at every test level

Importance of Testing

Testing is context-dependent and has no single universally applicable approach
Testing is done differently in different contexts
Absence-of-defects fallacy: thoroughly testing all specified requirements and fixing all defects found does not ensure the success of a system
Validation should be carried out in addition to verification to ensure the system fulfills users' needs and expectations

Test Activities, Testware, and Test Roles

Testing involves common sets of test activities, including dynamic testing, test planning, management, estimation, monitoring, and control
Testing requires specialized knowledge, analytical skills, critical thinking, and systems thinking
Tools are used in testing, but it is an intellectual activity that requires human effort and skills

Test Objectives

Typical test objectives include evaluating work products, triggering failures, ensuring coverage, reducing risk, verifying requirements, and providing information to stakeholders
Objectives of testing can vary depending on the context, including the work product being tested, test level, risks, SDLC, and business context
