What is Adhoc Testing? Example, Advantages, and Disadvantages,

What is Adhoc Testing?

Adhoc testing is an informal and unstructured approach to software testing that involves performing tests without following predefined test cases or plans. It is a technique where testers use their knowledge, experience, and intuition to identify defects and issues in the software. Adhoc testing is often done on the fly, with testers exploring the application and performing tests based on their understanding of the system. This type of testing is highly flexible and can be performed at any stage of the software development lifecycle.

Types of Adhoc Testing

1) Buddy Testing

Buddy testing involves two testers working together as a team. One tester assumes the role of the “buddy” or observer while the other tester performs the actual testing activities. The buddy closely watches the testing process, provides feedback, suggests test scenarios, and actively participates in the exploration. This collaborative approach helps in uncovering defects and gathering different perspectives, ultimately improving the overall effectiveness of adhoc testing.

2) Pair Testing

Pair testing is similar to buddy testing, but it involves two testers actively working together throughout the testing process. Both testers share responsibilities, switch roles, and discuss their observations and findings. This type of adhoc testing encourages collaboration, brainstorming, and diverse thinking. It allows for the sharing of knowledge and expertise, leading to a more comprehensive exploration of the software and the identification of potential defects.

3) Monkey Testing

Monkey testing, also known as random testing or gorilla testing, involves testers performing random and unpredictable actions on the software. A Software testing company in India & software testers simulate user interactions by randomly clicking buttons, entering inputs, and navigating through the application without following a specific test plan or predefined scenarios. The goal is to provoke unexpected behaviours and uncover any flaws or defects that may occur under random or excessive user input. Monkey testing helps in identifying crashes, freezes, memory leaks, and other issues related to robustness and stability.

Advantages of Adhoc Testing

1) Flexibility

Adhoc testing allows testers to freely explore the software, making it adaptable to changing requirements and allowing for quick testing iterations.

2) Real-World Perspective

Adhoc testing helps uncover defects that may occur in real-world usage scenarios, providing a more realistic perspective on the software’s behaviour.

3) Early Defect Identification

Adhoc testing often uncovers defects that may have been missed during formal testing, enabling early identification and resolution of issues.

4) Eddicient for Quick Checks

Adhoc testing is a time-efficient approach for performing quick checks and identifying obvious defects without the need for extensive test case preparation.

5) Creativity and Intuition

Adhoc testing allows testers to apply their creativity, experience, and intuition to explore different paths, leading to the discovery of unexpected defects and issues.

Disadvantages of Adhoc Testing

1) Lack of Documentation

Adhoc testing lacks formal documentation, making it difficult to reproduce tests or share findings with the development team.

2) Incomplete Coverage

Adhoc testing may not provide comprehensive coverage of the software as it relies on the tester’s judgment and exploration, potentially overlooking certain functionalities or scenarios.

3) Unpredictable Results

The results of adhoc testing can be inconsistent and unpredictable, varying based on the tester’s skills, knowledge, and testing approach.

4) Time-Consuming

Adhoc testing can be time-consuming as testers spend time exploring different paths and functionalities without a predefined plan, potentially leading to longer testing cycles.

5) Reliance on Tester Expertise

Adhoc testing heavily relies on the tester’s skills, experience, and knowledge, making it essential to have skilled testers capable of effectively identifying and reporting defects.

It’s important to note that while adhoc testing has its advantages, it should be used judiciously and in conjunction with structured testing techniques to ensure comprehensive test coverage and reliable results.

An Example of Adhoc Testing

Let’s consider a scenario where a team is testing a web-based e-commerce application:

1) Error Guessing

The tester decides to test the checkout process and deliberately enters an invalid credit card number to see how the system handles the error. The objective is to identify if the application correctly detects and handles invalid credit card information.

2) Exploratory Testing

The tester explores the application by randomly selecting products, adding them to the cart, and performing various actions such as modifying quantities, applying discounts, and selecting different shipping options. The goal is to uncover any unexpected behaviour, such as incorrect calculations, broken links, or usability issues.

3) Random Testing

The tester randomly clicks on different elements of the application, such as buttons, links, and menu options, without following a specific test plan. This includes clicking on a button multiple times rapidly to check if it causes any errors, or navigating to different pages in a non-linear manner to identify any inconsistencies or unexpected responses.

4) Monkey Testing

The tester performs random and continuous interactions with the application, simulating the actions of a user who may click or input rapidly and haphazardly. For example, the tester may randomly click on different areas of the website, submit forms with incomplete or incorrect information, or rapidly switch between different pages. The goal is to observe how the application handles such random and excessive user input, identifying any crashes, freezes, or unexpected behaviours.

5) User Perspective Testing

The tester simulates real-world scenarios from a user’s perspective. This could involve testing the application on different devices and browsers and checking for responsive design and cross-browser compatibility. The tester might also perform common user actions such as creating an account, adding items to the wishlist, or searching for products to ensure the functionality and usability of the application from the user’s standpoint.


In conclusion, adhoc testing is a valuable and flexible approach in software testing companies in Bangalore India. It offers advantages such as flexibility, real-world perspective, early defect identification, efficiency for quick checks, and the utilization of creativity and intuition. However, it also has limitations including a lack of documentation, incomplete coverage, unpredictable results, time-consuming nature, and reliance on tester expertise. When used alongside structured testing techniques, adhoc testing can significantly contribute to the overall quality and user experience of software products.
