Condition Determination Testing and Coverage. ISTQB White-box Techniques with TestCompetence
0 likes5,065 views
This document discusses condition determination testing and coverage. It defines condition determination testing as a white box test design technique where test cases independently affect decision outcomes that have been exercised by a test suite. 100% condition determination coverage implies 100% decision condition coverage. Examples of condition determination coverage for different code structures like IF/ELSE, SWITCH, WHILE, and nested conditions are provided.

- 1. Condition Determination Testing and Coverage with Prepare yourself for the ISTQB exam
- 2. Dictionary condition determination testing: A white box test design technique in which test cases are independently affect a decision outcome that have been exercised by a test case suite.100 % condition determination coverage implies 100 % decision condition coverage condition determination coverage: The percentage of all single condition outcomes that independently affect a decision outcome that have been exercised by a test case suite. 100% condition determination coverage implies 100% decision condition coverage.

- 3. Rules!! Condition determination testing - the possible combinations of true/false conditions that can affect decisions (branches) are identified. 100% multiple condition coverage implies 100% condition determination coverage modified condition decision coverage (MC/DC) = condition determination coverage modified multiple condition coverage = condition determination coverage modified condition decision testing = condition determination testing modified multiple condition testing = condition determination testing From „Certified Tester Advanced Level Syllabus (version 2007)” Copyright © 2013

- 5. Examples with IF h = lqy + rh * enh; IF (cc && t || mva) { In order to cover all tw = k - f / j; modified multiple } conditions, you need 4 test cases. Copyright © 2013
- 6. Examples with IF ELSE IF (ta && k && a) { p = ucc - wk - g; In order to cover all } modified multiple ELSE conditions, you need { 4 test cases. j = c / cws - ld; } gwe = pzn - wv; Copyright © 2013
- 7. Examples with SWITCH ol = or * k + zbo; SWITCH (hz) { In order to cover all CASE 0: modified multiple m = g + pwu; conditions, you need break; 2 test cases. CASE 1: h = pgm + xh; break; } Copyright © 2013
- 8. Examples with WHILE zl = ff * br; vf = -5; WHILE (o && n || vf < 1) In order to cover all { modified multiple yxx = uum / azc / p; conditions, you need vf++; 3 test cases. } Copyright © 2013
- 9. Examples with FOR FOR (mq = -4; mq > -8; mq--) { In order to cover all dsq = q * ry - tqw; modified multiple } conditions, you need 1 test case. Copyright © 2013

More examples mz = e / jxu * du; ldy = rt + p; IF (foi || xpm) { In order to cover all IF (gt || k || g) modified multiple { conditions, you need tmr = qjy + w / br; 5 test cases. } ELSE { IF (yi || n && bk) { bwi = tl + be + eae; } ELSE { lz = gz - eg * qp; } } } ELSE { sts = ap * yv; } Copyright © 2013
- 11. More examples s = 12; WHILE (dfy && o || s > -1) { tjj = d + ce; In order to cover all s--; modified multiple } conditions, you need cb = -8; 5 test cases. WHILE (jdh && byw || cb < 1) { x = 14; WHILE (dvc && w || x > 8) { tec = -16; WHILE (t && ll || tec < -8) { n = gp * co + lv; tec++; } x--; } cb++; } Copyright © 2013
