Question set 07


The usual (correct) sequence of testing is:

·         Integration tests, unit tests, system tests

·         unit testy, integration tests, system tests

·         system tests, integration tests, unit tests

Testing can reveal:

·         performance

·         errors

·         absence of defects

Testing with knowledge of internal SW structure is called as:

·         Verification

·         Validation

·         Whitebox testing


Testing against SW functional specification is called as:

·         Validation

·         Whitebox testing

·         Blackbox testing

The V-Model:

·         Shows that each development phase has respective testing activities

·         Illustrates both validation and verification effort

·         Implies that you can start testing even when the code is not yet written


Test Drivers are used during:

·         Unit tests

·         Top-down integration testing

·         Bottom-up integration testing

So-called „stubs“ are used during:

·         Unit tests

·         Top-down integration testing

·         Bottom-up integration testing


Cyclomatic complexity shows how elaborate is:

·         Whitebox testing

·         Blackbox testing

·         Integration testing

The testing activities are most efficient when:

·         it is performed by author of the code

·         it is performed by a quality team which does not cooperate with developers

·         quality team cooperates with developers team


Choose what applies to testing:

·         complete testing is possible, but only for simple programs with very low cyclomatic
complexity

·         complete testing is never possible

·         complete testing is usually not possible, even for simple programs if they have high
cyclomatic complexity


Majority of defects result from improper:

·         requirements collection

·         system architecture

·         errors during programming


Successful test:

·         confirms existence of known defect

·         confirms absence of known defect

·         confirms existence of not-yet-known defect

·
