Pair testing strategy in an Agile environment

From the histogram, we see that there are no very unusual points, or outliers. The data are roughly bell-shaped, so our idea of a normal distribution for the differences seems reasonable. Each of the paired measurements are obtained from the same subject.

Pairing a tester with a product manager helps them understand the business perspective and the customer problems they can solve. Pair testing is all about doing testing in a group of two. It means a tester and developer or even two testers working together to get things done. Since the tester leads the pair test session, they can team up with other specialized professionals such as customer support, product manager, or marketing manager.

It also aids in the comprehensive comprehension of the program. People who have been working on the same program for a long time are familiar with the functionality and may not have what is pair testing the correct set of eyes for an end-user perspective. A new set of eyes may see something that was previously missed. Testers typically pair up with developers or other testers.

  • The newness allows them to notice some critical bugs and provide valuable feedback to the team.
  • If your sample size is very small, it is hard to test for normality.
  • The other directs the test process, asks questions, makes suggestions, notes down results, leaves comments, and more.
  • Rotating roles regularly helps keep both developers alert and engaged.
  • Video conferencing tools enable remote pairing by sharing a screen or remotely controlling others’ mouse and keyboards.
  • It ensures that two people perform testing for the same scenario instead of one so that high-value testing results are obtained utilizing the dual capabilities of both individuals.
  • Use the information from previously conducted testing sessions to improve your testing outputs.

To compare paired means for continuous data that are not normally distributed, choose the nonparametric Wilcoxon Signed-Ranks Test. The purpose of the test is to determine whether there is statistical evidence that the mean difference between paired observations is significantly different from zero. Like when paring with engineer, it is not common to only code for happy path. There are two significant style pf pairing; one traditional and the other strong-style (Maaret Pyhäjärvi, 2018).

One of the keys for implementation is thinking about the driver and navigator roles.

According to a blog post on Raygun, pairs work about 15% slower, which is an improvement but is still less than the productivity of two separate programmers. This Agile software development technique is not well suited for everyone, however. Learning to partner effectively in a team that close and share a work computer takes skills that not all programmers possess.


A tester and a developer are chosen as part of this activity. This style works well for a novice paired with an expert programmer. The navigator role can range from a reserved approach to a tactical hands-on role.

The paired t-test is also known as the dependent samples t-test, the paired-difference t-test, the matched pairs t-test and the repeated-samples t-test. The paired t-test is a method used to test whether the mean difference between pairs of measurements is zero or not. There is also a sneaky catch – test generators like jenny assume that the order of variables is irrelevant.

One individual can use a mouse and keyboard to run a test. The other one can be in charge of the test process, ask questions, give suggestions on an existing design, note down results, and more. They ensure that the overall functionality, usability, and design aspects are reviewed as part of application testing. When a new project begins with the new team members there often a hurdle between testers and developers.

Reporting bugs after the session – Though testers note some details about the bug during the pair testing session. Several testers defer writing detailed bugs to focus on testing to maximize the outcome of pair testing. Reproducing and logging the bugs at the end of the session can turn out to be time-consuming and cumbersome. 60 minutes – Focused time for the pair to explore the application.

Checking the data

Most pair programming relationships fall into the unstructured style, where two programmers work together in an ad hoc manner and collaboration is loosely guided. A common variant of this style is the unstructured expert-novice pair, where an expert programmer and a novice are paired together. Junior developers can pick up more skills from senior developers. And those unfamiliar with a process can be paired with someone who knows more about the process. The two developers take turns coding or reviewing and check each other’s work as they go.

Moreover, this can help testers from different teams to build better bonds and support each other in their releases. Explain your vision and the impact the new initiative can bring, explain the benefits of pair testing and resolve their concerns. If a developer requests that you investigate a feature and see how it works, you may find yourself in a session where some code is rewritten or even new code is created. The result of the pair session is new or rewritten code, and the developer is in charge. When you ask a developer to check into an issue you’ve discovered in his code, you’re evaluating if it’s a test error or a real problem together. The pair session yields information on whether the problem is a bug, and the tester is in command.
