Condition coverage in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Condition Coverage in software testing?

Condition Coverage measures whether each individual condition in a decision has been tested with both true and false outcomes at least once.

beginner

Why is Condition Coverage important?

It helps find errors in complex decisions by ensuring every condition is tested independently, improving test thoroughness.

How does Condition Coverage differ from Decision Coverage?

Decision Coverage checks if each decision (like an if statement) is true or false, while Condition Coverage checks each part inside the decision separately.

intermediate

Example: For the decision if (A && B), what must tests cover for full Condition Coverage?

Tests must make A true and false, and B true and false, regardless of the overall decision outcome.

beginner

Can Condition Coverage guarantee all bugs are found?

No, it improves testing but does not guarantee all bugs are found because it tests conditions independently, not all combinations.

What does Condition Coverage ensure in testing?

A Each condition in a decision is tested as true and false

B Each decision is tested as true and false

C All possible combinations of conditions are tested

D Only the true outcomes of conditions are tested

Condition Coverage requires each condition to be tested with both true and false values.

Which of the following is an example of a condition in if (X || Y)?

A X || Y

B X

C if statement

D Y && X

X and Y are single conditions inside the decision.

Condition Coverage is a type of:

A Performance testing

B Functional testing

C Usability testing

D Structural testing

Condition Coverage is structural because it tests the code's internal logic.

If a decision has two conditions, how many condition outcomes must be tested for full Condition Coverage?

A 4

B 2

C 1

D 3

Each condition must be tested true and false, so 2 conditions × 2 outcomes = 4.

Which coverage type tests all possible combinations of conditions?

A Condition Coverage

B Decision Coverage

C Multiple Condition Coverage

D Statement Coverage

Multiple Condition Coverage tests all combinations of condition outcomes.

Explain what Condition Coverage is and why it is useful in software testing.

Think about testing each part inside an if statement separately.

Describe the difference between Condition Coverage and Decision Coverage with an example.

Focus on testing individual conditions vs whole decisions.
