Software Engineering: White-box Testing (Definitions)

"An implementation-based test, in contrast to a specification-based test" (Johannes Link & Peter Fröhlich, "Unit Testing in Java", 2003)

"This test is derived knowing the inner structure of the software and based on the program code, design, interface descriptions, and so on. White-box tests are also called» structure based tests." (Lars Dittmann et al, "Automotive SPICE in Practice", 2008)

[white box test design technique:] "Any technique used to derive and/or select test cases based on an analysis of the internal structure of the test object (see also structural test)." (Tilo Linz et al, "Software Testing Foundations" 4th Ed., 2014)

"A software testing methodology that examines the code of an application. This contrasts with black box testing, which focuses only on inputs and outputs of an application." (Mike Harwood, "Internet Security: How to Defend Against Attackers on the Web" 2nd Ed., 2015)

"A test designed by someone who knows how the code works internally. That person can guess where problems may lie and create tests specifically to look for those problems." (Rod Stephens, "Beginning Software Engineering", 2015)

"The testing method where test cases are generated in order to test a program at a source code level." Pedro Delgado-Pérez et al, "Mutation Testing", 2015)

"A testing technique to test the internal structure, design and coding of a software solution." (Pooja Kaplesh & Severin K Y Pang, "Software Testing, Software Engineering for Agile Application Development", 2020)

"A test methodology that assumes explicit and substantial knowledge of the internal structure and implementation detail of the assessment object." (NIST SP 800-137)

[white-box test design technique:] "Procedure to derive and select test cases based on an analysis of the internal structure of a component or system." (ISTQB)

"Testing based on an analysis of the internal structure of the component or system." (ISTQB)
