- Component Inspection. -Usability Testing. -Unit Testing. -System Testing.

-Finds faults in a component by reviewing its source code in a formal meeting. The inspection is conducted by: -A team of developers. -Including the author of the component. -A moderator. -One or more reviewers.

-The first structured inspection process was Michael Fagan’s inspection method, it consists of: - Overview -Preparation -Inspection meeting -Rework -Follow-up

-Tests the users under standing of the system. There are three types of testing: -Scenario Test. -Prototype Test. -Product Test.

In all three tests, the basic elements of usability testing include: -Development of test objectives. -A representative sample of end users. -The actual or simulated work environment. -Controlled extensive interrogation, and probing of the users. -Collection and analysis of quantitative and qualitative results. -Recommendations on how to improve to system.

Focuses on the building blocks of the software system,that is,objects and subsystems. There are three motivations behind focusing on components: -First: unit testing reduce the complexity of the overall test activities. -Second: unit testing make it easier to pinpoints and correct faults. -Third: unit testing allows parallelism in the testing activities.

Below are the most important unit testing techniques: -Equivalence testing. -boundary testing. -path testing. -state-based testing.

Ensures that the complete system complies with the functional and nonfunctional requirements. Several system testing activities are performed: -Functional testing. -Performance testing. -Pilot testing. -Acceptance testing. -Installation testing.

-The steps of Michael Fagan’s inspection method are: -Alpha and beta testing -stress and time testing -Overview, preparation,inspection meeting, rework, and follow-up -Coverage means: -No input belongs to more than one equivalence class. -every possible input belongs to one of the equivalence classes. -none of the above. -Stress, volume, security, timing and recovery tests are performed during: -Functional test-Performance test-Pilot test
