Adhoc Testing In Software Testing With Example

Adhoc testing in software testing is an informal and unstructured approach where testers explore the software application without predefined test cases or plans. Here’s a real-time example to illustrate adhoc testing:

Imagine a team of testers working on a social media application. During adhoc testing, one tester decides to explore the functionality related to posting images. Instead of following a scripted test case, they decide to take an exploratory approach.

The tester starts by uploading images of various sizes, resolutions, and formats to examine how the application handles them. They purposely select images that are larger than the allowed file size, expecting the application to display an error message indicating the limitation. This helps in validating the input validation and error handling capabilities of the application.

Next, the tester tries uploading images with unusual file extensions, like .txt or .mp3, to see if the application correctly identifies and rejects unsupported file types. This ensures the application handles file format compatibility appropriately.

Furthermore, the tester tries different image orientations, such as landscape and portrait, to ensure the application displays them correctly and maintains aspect ratios.

During this adhoc testing session, the tester also explores the user interface (UI) elements related to image posting. They randomly click on buttons, drag and drop images, and try different gestures to ensure all the image-related features function as intended.

In addition to validating the image upload functionality, the tester also takes the opportunity to perform adhoc testing on other related areas. For instance, they check if uploaded images appear correctly in posts, comments, or user profiles.

They try posting images from various locations within the application, such as direct messaging or group chats, to verify consistent behavior across different contexts.

Through this real-time example, it becomes evident that adhoc testing allows testers to think creatively, simulate real-world scenarios, and uncover potential defects or usability issues that may not be addressed by predefined test cases.

It provides flexibility in exploring specific areas of concern and helps improve the overall quality of the software application.

Adhoc Test Purpose

In this section we will see the purpose of adhoc testing in software testing

  • Discover defects
  • Validate functionality
  • Improve overall quality
  • Test boundary conditions
  • Enhance user experience
  • Identify compatibility issues
  • Supplement structured testing
  • Discover defects: Uncover hidden issues and flaws in the software.
  • Validate functionality: Ensure that the software performs its intended tasks correctly.
  • Improve overall quality: Enhance the overall reliability and performance of the software.
  • Test boundary conditions: Assess how the software behaves at its limits and edge cases.
  • Enhance user experience: Improve the usability and satisfaction of the software for users.
  • Identify compatibility issues: Check if the software works well across different platforms and configurations.
  • Supplement structured testing: Provide additional testing to complement formal test plans and uncover unforeseen issues.

When To Perform Adhoc Testing

In this section we will see when to perform adhoc testing

  1. Exploratory Testing: Use adhoc testing to explore the software and uncover potential issues that might not be covered by formal test cases.
  2. Time Constraints: When there is limited time for extensive testing, adhoc testing can be used to quickly identify critical defects.
  3. New Features or Changes: Perform adhoc testing when new features or changes are implemented to ensure they work as expected and do not introduce any unintended side effects.
  4. Regression Testing: After fixing bugs or making changes, adhoc testing can help verify that the fixes or changes have not caused any new issues.
  5. Real-World Scenarios: Adhoc testing can simulate real-world usage scenarios to test the software under different conditions and user interactions.
  6. User Feedback: When users report unexpected behavior or issues, adhoc testing can be used to reproduce and investigate those problems.
  7. Adhoc Testing Sessions: Dedicated adhoc testing sessions can be conducted periodically to proactively search for defects and improve overall product quality.


It’s important to note that while adhoc testing is valuable, it should not replace structured and planned testing methodologies.

Adhoc Testing Types

In this section we will see what all are the adhoc testing types:

  • Monkey Testing
  • Error Guessing
  • Sanity Testing
  • Compatibility Testing
  • Usability Testing
  • Security Testing
  • Performance Testing
  • Localization Testing
  • Recovery Testing
  • Installation Testing

Adhoc Testing Vs Exploratory Testing

In this section we will see comparison of Adhoc Testing and Exploratory Testing:

CriteriaAdhoc TestingExploratory Testing
PurposeTo identify defects through random testingTo discover defects, learn, and understand the system
ApproachUnplanned and unstructured testingPlanned but flexible testing
Test PlanningMinimal or no test planning involvedSome level of test planning may be involved
Test CasesNo predefined test casesTest cases are created on-the-fly
Time AllocationPerformed as and when neededContinuous testing throughout the project
DocumentationMinimal documentationDocumentation is not the primary focus
Test CoverageLimited coverage of specific areasComprehensive coverage based on tester’s expertise and intuition
FocusMainly on basic functionality and critical areasBroad focus on various aspects of the system
Defect DiscoveryRelies on chance discovery of defectsActively searching for potential defects
LearningLimited learning opportunity during testingHigh learning opportunity during testing
Skills RequiredBasic knowledge of the system under testStrong understanding of the system and domain
ReproducibilityMay not be reproducibleCan be reproduced for further investigation


It’s important to note that both Adhoc Testing and Exploratory Testing can complement each other and be used in combination to ensure comprehensive testing.

Monkey Testing Vs Adhoc Testing

In this section we will see comparision between monkey testing and adhoc testing:

CriteriaMonkey TestingAdhoc Testing
PurposeTo randomly test the software for unexpected behavior or crashesTo identify defects through unplanned and unstructured testing
ApproachRandom interactions with the softwareUnplanned and unstructured testing
Test PlanningMinimal or no test planning involvedMinimal or no test planning involved
Test CasesNo predefined test casesNo predefined test cases
Time AllocationPerformed as and when neededPerformed as and when needed
DocumentationMinimal documentationMinimal documentation
Test CoverageRandom coverage of various areasLimited coverage of specific areas

ReproducibilityMay not be easily reproducibleMay not be easily reproducible
LearningLimited learning opportunity during testingLimited learning opportunity during testing
Skills RequiredBasic knowledge of the software under testBasic knowledge of the software under test
Defect DiscoveryRelies on chance discovery of defectsRelies on chance discovery of defects


Monkey Testing and Adhoc Testing serve different purposes. Monkey Testing is mainly focused on randomly interacting with the software to identify unexpected behavior or crashes, while Adhoc Testing involves unplanned and unstructured testing to identify defects. Both approaches can be used to complement each other and enhance overall testing coverage.

Adhoc Testing With Automation

Adhoc testing can also be performed using automation tools. Here’s how adhoc testing can be combined with automation:

  1. Test Environment Setup: Set up the test environment with the required automation tools and frameworks.
  2. Test Data Preparation: Prepare the necessary test data for the adhoc tests. This can include various scenarios, inputs, and data combinations.
  3. Automation Scripting: Write automation scripts to perform adhoc tests. These scripts can simulate random user actions, inputs, and interactions with the application.
  4. Random Test Execution: Execute the automation scripts in a random manner, allowing them to perform a variety of actions and inputs. This will help uncover unexpected behavior or defects.
  5. Error Handling and Reporting: Handle any errors or exceptions encountered during the test execution. Capture and log relevant information for further analysis.
  6. Logging and Documentation: Maintain proper logs and documentation of the adhoc test scenarios executed, including any defects or issues identified.
  7. Iterative Testing: Repeat the adhoc testing process iteratively, introducing new test scenarios and data combinations to maximize test coverage.

By combining adhoc testing with automation, you can achieve faster and more efficient testing while still maintaining the exploratory nature of adhoc testing. Automation can help in executing repetitive tasks and capturing detailed results, allowing you to focus on the analysis and investigation of uncovered issues.
