TEST TYPES

1. Functional testing

1.1. based on ISO 9126

1.2. suitability, interoperability, security, accuracy, comliance

1.3. based on requirements or business-process

1.4. is mostly a validation technique

1.5. is referred to as black-box testing

2. Non-functional

2.1. based on ISO 9126. The characteristics (and sub-characteristics):

2.1.1. functionality (suitability, accuracy, security, interoperability and compliance)

2.1.2. reliability (maturity (robustness), fault-tolerance, recoverability and compliance)

2.1.3. usability (understandability, learnability, operability, attractiveness and compliance)

2.1.4. efficiency (time behavior (performance), resource utilization and compliance)

2.1.5. maintainability (analyzability, changeability, stability, testability and compliance)

2.1.6. portability (adaptability, installability, coexistence, replaceability and compliance)

2.2. performance, load, stress, usability maintainability, reliability, portability

3. Structural testing

3.1. testing of software structure/architecture

3.2. structural-based technique

3.3. is often referred to as 'white-box' or 'glass-box'

4. Confirmation (retesting) & Regression
