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.

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

bs = yan + bq + ad;
h = e * bja;
There are no conditions to
cover.

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.

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;

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;
}

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.
}

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.

ldy = rt + p;
IF (foi || xpm)
{ In order to cover all
IF (gt || k || g) modified multiple
{ conditions, you need

5 test cases.

s = 12;
WHILE (dfy && o || s > -1)
{
tjj = d + ce; In order to cover all
s--; modified multiple

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++;
