Pair Testing
Pair testing is a collaborative testing technique in which two people work together at one workstation to design, execute, and analyze tests.
“A test approach in which two team members simultaneously collaborate on testing a work product.”

Pairs often consist of testers, developers, business analysts, or other stakeholders who combine their knowledge to improve defect detection and learning.
Collaboration: Two participants contribute complementary skills.
Knowledge sharing: Participants learn from each other during testing.
Improved quality: Different perspectives often uncover additional defects.
Real World Example
A regulated product team is preparing a release where Pair testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Pair testing as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Pair testing and similar ideas.
The page becomes useful in practice because Pair testing is connected to a specific testing decision, not memorized as a detached definition.
