Test Levels and Test Types

Two questions from ISTQB (Foundation Level)

QUESTIONSQuestion 1. Which of the following is a test type?a. Component testingb. Functional testingc. System testingd. Acceptance testing

Question 2. A regression test:a. Is only run once.b. Will always be automated.c. Will check unchanged areas of the software to see if they have been

affected.d. Will check changed areas of the software to see if they have been

affected.

Test LevelsTesting is not a stand-alone activity. It has its place within

a software development life cycle.V-model

Test TypesTest types are introduced as a means of clearly defining the

objective of a certain test level for a programme or project.

A test type is focused on a particular test objective, which could be the

• testing of a function to be performed by the component or system;

• a non-functional quality characteristic, such as reliability or usability;

• the structure or architecture of the component or system;• or related to changes, i.e. confirming that defects have

been fixed (confirmation testing, or re-testing) and• looking for unintended changes (regression testing).

Test Levels and TypesWhich of the following are test types and which are

test levels?1. Functional testing2. Component testing3. Integration testing4. Structural testing5. Confirmation and Regression testing6. System testing7. Non-functional testing8. Acceptance testing
