A vital software testing technique, pair testing session involves two individuals or team members, who work on a single workstation/keyboard to test various aspects of a software application. This type of testing basically comes under ad-hoc testing and aims at pairing two individuals to work on same software product and on the same machine.
During pair testing, both the individuals are responsible for different tasks that validate the quality as well as the functionality of the software. While one of them executes the process of testing, the other member is responsible for analysing and reviewing the process. Hence, with the assistance of this approach one can rapidly perform thorough software testing, while saving time and money.
To offer you a better insight into this type of software testing, mentioned below are some of the features of pair testing.
The answer to the above question is quite simple. In this process of testing, "Two head is better than one".
Pair testing involves incoming of ideas, strategies, scenarios, plans, solutions and many other things, which may or may not be exclusive from two different resources. This ensures the wide test coverage along with exchange of ideas and reviews to explore more and unseen defects in the minimal time.
Any combination can work effectively and efficiently in pair testing. The possible pairs could be - tester & tester, tester & developer and tester & user. A tester needs to be one of the members of the pair. However, each pair has its own significance. Let's go through each of these pair.
This pairing of tester and developer ensures the mutual understanding of each other's process. This pair is effective as one is aware of the complete development process and may impart knowledge and understanding of the software technicalities to the tester in order to identify and locate defects easily in a shorter period of time. Inclusion of a developer in the pair enables tester to understand the complexities of the software product.
This type of testing is based on the methodology where the members of the pair will test the same product by making use of the same resources such as machines or computers. Generally, one works on paper in taking notes preparing scenarios, including reviews and analysis of the test results, while another is responsible for carrying out testing procedures on machines or computer by making use of the other member's output.
However, the places of these members may not be fixed, they could be interchangeable. After each defined session or some interval of time, the members may exchange their positions.
The process of pair testing is an extremely beneficial one. It offers various advantages to the team as well as the product owner. During pair testing, the team works in an agile environment and execute the process of testing together. Other advantages of pare testing are:
Though, pair testing is an extremely beneficial testing technique, there are few challenges that are encountered by the team while executing its process. These challenges are:
Since the significance of pair testing is monumental in software testing life cycle, it becomes vital for the team to execute it without missing out critical elements. Therefore, to help you ensure this, following are some tips to improve pair testing:
|Pair Testing||Pair Programming|
|1. Pair testing is an agile software testing technique, which is also known as Buddy Testing.||1. Pair programming is an agile software development technique.|
|2. The process is performed by any two individuals, whose roles are interchangeable.||2. The process is performed by two programmers, who switch their roles frequently.|
|3. The team can consist of a tester, business analyst, developer, programmer, etc.||3. The team members are known as driver and observer/navigator.|
|4. The team is focused on testing the software and ensuring its compliance with specified requirements.||4. The team is focused on designing and analyzing the code as well as the product.|
|5.It helps narrow down the root cause of a problem, while continuously testing it.||5.It defines how good a software works.|
|6. Does not require internal knowledge of the structure.||6. Pair programming is a part of Extreme Programming.|
In a nutshell, it may be stated that pair testing is a useful testing approach that utilizes the skill-sets and knowledge of two minds on one product to reveal the flaws and issues present in it, in an efficient and effective manner.
