Chapter 4 Test techniques Flashcards
Test technique (test case technique, test specification technique, test design technique)
A procedure used to derive and/or select test cases.
Black-box test technique
A procedure to derive and/or select test cases based on an analysis of the specifiation, either functional or non-functional, of a component or system, without reference to its internal structure.
White-box test technique
A procedure to derive and/or select test cases based on an analysis of the internal structure of a component or system.
Coverage
The degree to which specified coverage items have been determined to have been exercised by a test suite, expressed as a percentage.
Equivalence partitioning (partition testing)
A black-box test technique in which test cases are designed to exercise equivalence partitions by using one representative member of each partition.
Equivalence partition (equivalence class)
A portion of the value domain of a data element related to the test object for which all values are expected to be treated the same based on the specification.
Boundary value analysis
A black-box test technique in which test cases are designed based on boundary values.
Decision table testing
A black-box test technique in which test cases are designed to execute the combination fo inputs and/or stimulie (causes) shown in a decision table.
State transition testing (finite state testing)
A black-box test technique using a state transition diagram or state table to derive test cases to evaluate whether the test item successfully executes valid transitions and blocks invalid transitions.
Use case testing (scenario testing, user scenario testing)
A black-box technique in which test cases are designed to execute scenarios of use cases.
Statement coverage
The percentage of executable statements that have been exercised by a test suite.
Decision coverage
The coverage of decision outcomes.
Error guessing
A test technique in which tests are derived on the basis of the tester’s knowledge of past failures, or general knowledge of failure modes.
Exploratory testing
An approach to testing whereby the testers dynamically design and execute tests based on their knowledge, exploration of the test item and the results of previous tests.
Checklist-based testing
An experience-based test technique whereby the experienced tester uses a hight-level list of items to be noted, checked, or remembered, or a set of rules or criteria against which a product has to be verified.
