What testing approach involves two team members collaborating simultaneously on a work product?

The testing approach that involves two team members collaborating simultaneously on a work product is known as pair testing. In this method, both testers work together at the same workstation, sharing their expertise and perspectives to explore the application under test more thoroughly. This collaboration fosters real-time communication, allows for immediate feedback, and can lead to identifying defects that may not be caught by an individual tester working alone.

Pair testing is particularly effective in agile environments where teamwork and rapid iteration are key. It promotes knowledge sharing and helps to build a common understanding of the product among team members, enhancing the overall quality of testing. Engaging in pair testing can also lead to more innovative ideas and solutions as the two testers bounce concepts off each other, improving problem-solving.

Other approaches mentioned differ in their collaboration style. Independent testing is carried out by testers who work separately from the development team, potentially missing out on collective insights. Group testing usually involves several testers but does not emphasize the direct and constant collaboration that pair testing fosters. Sequential testing involves testers completing their tasks one after another, which lacks the real-time interactive learning aspect of pair testing.
