Editing White-box testing (section)

== Overview ==
White-box testing is a method of testing the application at the level of the source code. These test cases are derived through the use of the design techniques mentioned above: [[control flow]] testing, data flow testing, branch testing, path testing, statement coverage and decision coverage as well as modified condition/decision coverage. White-box testing is the use of these techniques as guidelines to create an error-free environment by examining all code.  These white-box testing techniques are the building blocks of white-box testing, whose essence is the careful testing of the application at the source code level to reduce hidden errors later on.<ref name=level>{{cite web|last=Williams|first=Laurie|author-link=Laurie Williams (software engineer)|title=White-Box Testing|pages=60–61, 69|url=http://www.chaudhary.org/WhiteBox.pdf|access-date=13 February 2013|archive-date=3 March 2016|archive-url=https://web.archive.org/web/20160303194843/http://www.chaudhary.org/WhiteBox.pdf|url-status=dead}}{{Verify source|date=February 2013}}</ref> These different techniques exercise every visible path of the source code to minimize errors and create an error-free environment. The whole point of white-box testing is the ability to know which line of the code is being executed and being able to identify what the correct output should be.<ref name=level />
