Test-reduction - Doing more with less

Ewald

Are your unit tests actually spotting bugs, or just padding coverage metrics? Learn how mutation and property-based testing dramatically reduce boilerplate while aggressively catching critical edge cases.

#1 about 3 min

Understanding the chore and effort of unit testing

Treating unit testing as an afterthought leads to uncertainty about when testing is effectively complete.

#2 about 3 min

Distinguishing code coverage and test coverage metrics

Measuring executed lines of source code fails to reflect the actual quality of test assertions.

#3 about 3 min

Evaluating test suite quality through mutation testing

Introducing deliberate logic changes into source code verifies whether tests accurately capture unexpected behavior.

#4 about 3 min

Finding edge cases beyond simple error guessing

Relying purely on intuition for initial test creation often misses essential edge cases.

#5 about 4 min

Scaling test cases with the decision table technique

Creating explicit test combinations manually becomes difficult to maintain as the number of variables increases.

#6 about 6 min

Generating complex edge cases using property-based testing

Defining required input properties rather than exact values enables automated generation of difficult technical edge cases.

#7 about 4 min

Reducing test efforts by applying risk-based testing

Balancing component failure probability against business impact helps testing teams apply appropriate validation techniques.
