The Complete Guide to Ad hoc Testing
By Kitakabee, Community Contributor - March 10, 2023
Ad hoc testing is a software testing technique performed without any specific test plan or predefined set of steps. Instead, testers use their intuition, experience, and creativity to identify defects and issues that more formal testing methods may not find.
This guide will explore the various aspects of ad hoc testing and provide tips on effectively performing it.
What is Ad hoc Testing
Ad hoc testing is an exploratory approach to software testing where the tester does not follow a predefined test plan but performs testing on an ad hoc basis.
Ad hoc testing focuses on identifying defects in the software that more structured testing approaches might miss. To uncover defects, testers can use random, exploratory, and boundary testing techniques.
It can be beneficial because it is flexible and can adapt to changing requirements or situations.
However, it can also be less thorough and inefficient than formal testing methods, as the testing is not planned, and the tester may overlook some important aspects of the software.
Advantages of ad hoc testing
Ad hoc testing can help you create a robust product and reduce its vulnerability to issues in the future. It offers several benefits such as:
- Flexibility: Ad hoc testing is a flexible approach that allows you to adapt to changing requirements or situations quickly. You can carry out an ad hoc test at any given point in a software development life cycle because there’s no limitation of a predefined test plan.
- Creativity: It encourages testers to use their creativity and intuition to identify defects in the software that more structured testing methods can’t spot. Testers can explore the software in a more open and freeform manner, which can lead to the discovery of unexpected issues.
- Early defect detection: Ad hoc testing can be performed early in the development cycle, even before a formal test plan is created. It can help identify defects and issues at an earlier stage, reducing the overall cost and effort of fixing them later in the development cycle. Compared to traditional testing, you can identify more flaws using the technique.
- Time and cost savings: The tester is not exposed to an additional load because documentation is unnecessary. The tester can focus on comprehending the underlying architecture. Ad hoc testing can be faster and more cost-effective, especially when the time or resources for more formal testing are limited. It can help quickly identify and resolve issues before they become more complex and expensive.
- Improved testing coverage: Ad hoc testing can complement more structured testing methods and help improve testing coverage by identifying defects that other approaches may miss. The testers can explore the program according to their comprehension and intuition. They can then run the specific tests as they go, assisting them in spotting mistakes.
However, it is important to note that ad hoc testing should not be the only approach used and should be complemented by more formal testing methods like regression testing and unit testing to achieve comprehensive testing coverage.
When to use ad hoc testing?
Testing teams have multiple things to test within limited timeframes. As testers focus on performing formal processes and executing numerous testing tasks, the chances of ad hoc testing are small to make it into the testing cycle.
It is executed when there isn’t time to finish extensive testing, which consists of creating test cases, test requirements documents, and test case designs.
Here are different situations where you can rely on ad hoc testing:
- Ad hoc testing can be used as a part of user acceptance testing, where end-users are encouraged to test the software in their environments and provide feedback.
- You can also use it as a part of exploratory testing, where testers explore the software in an unstructured manner to uncover defects and issues.
- Ad hoc testing can quickly validate the functionality and identify any issues when a new or unfamiliar feature is introduced.
- Although the best time to execute ad hoc is after the formal testing, you can use it early in the development cycle, before a formal test plan has been created, to identify defects and issues quickly.
- Also, when there is limited time available for testing, ad hoc can be a vital approach to identify faults quickly.
- You can also use the approach to test specific areas of the software that are known to be error-prone or have a history of defects.
Types of Ad hoc Tests
Here are some types of ad hoc testing you can commonly use:
- Exploratory testing: In exploratory testing, the tester uses their domain knowledge and experience to design and execute tests and record their observations and findings as they perform the tests. This testing type is used when the software is complex, poorly understood, or time constraints prevent a more formal testing approach. Exploratory testing is useful when there is a need for rapid testing, when requirements are unclear or changing rapidly, or when a quick assessment of the software is needed. It can be performed by experienced testers or developers and complement more structured testing approaches.
- Ad hoc functional testing: Ad hoc functional testing is a type of testing that focuses on the functional requirements of the software. It is performed without a predefined test plan, and the test team uses its experience and intuition to identify defects and issues related to the software’s functionality. During ad hoc functional testing, the test team can perform specific tests related to the functional requirements of the software but is also free to explore other areas of the software to identify defects and issues. This approach allows the test team to spot issues that are not identified through more structured testing methods.
- Ad hoc performance testing: Ad hoc performance testing is a type of testing that focuses on the performance of the software system. The goal of ad hoc performance testing is to identify potential performance issues or bottlenecks in the system by simulating real-world usage and load.
- Ad hoc security testing: During ad hoc security testing, you simulate specific attack scenarios or explore areas of the software that are likely to be vulnerable to attacks. It should be complemented by more formal security testing methods to ensure that all aspects of the software’s security have been thoroughly tested.
- Ad hoc usability testing: You can use ad hoc usability testing to test the software’s user interface and user experience. Being an informal approach, you can execute the test to identify usability issues like poor navigation, confusing layouts, or difficult-to-use features. It is effective in identifying usability issues and opportunities for improvement.
You can achieve comprehensive testing coverage once you blend these ad hoc testing techniques with other traditional testing approaches.
Preparing for Ad hoc Testing
Preparing for ad hoc testing involves several steps like:
1. Defining the test objectives
Before starting ad hoc testing, it is essential to clearly define the test objectives, including what aspects of the software, what types of defects or issues the testing will focus on, and what outcomes are expected.
To define the test objectives, the test team should consider the following questions:
- What is the purpose of the testing effort?
- What are the key areas of the software that need to be tested?
- What are the key risks associated with the software?
- What are the specific goals and outcomes that the testing are to achieve?
The test objectives should be specific, measurable, achievable, and documented in a test plan or other testing documentation.
2. Selecting the test team
Selecting the right test team is an important step in preparing for ad hoc testing and can help ensure that the testing effort is effective and aligned with the project’s overall goals.
The test team should be selected based on their skills, experience, and familiarity with the software being tested. It is important to have a diverse team that includes testers with different backgrounds and perspectives to help identify a wide range of defects and issues.
The following steps can be taken to select the test team:
- Identify the key skills and experience needed for the testing effort. This may include skills in software testing, programming, user experience design, or security testing.
- Identify individuals with the necessary skills and experience to participate in the testing effort.
- Determine the size and composition of the test team. The team size will depend on factors such as the complexity of the software being tested, the time available for testing, and the scope of the testing effort.
- Consider the diversity of the test team. A diverse team can provide a wider range of perspectives and approaches to testing, which can help identify a wider range of issues and opportunities for improvement.
Once the test team has been selected, it is important to ensure they have the necessary training and resources to perform ad hoc testing effectively. This may include training in specific testing tools or techniques, access to testing environments and data, and clear communication channels with the development team.
3. Identifying test environment and data requirements
The test environment should be set up to simulate the end-user environment as closely as possible. This includes the hardware, software, and network configurations. Additionally, the necessary test data should be identified and prepared to ensure the testing can be performed effectively.
It is also important for the test team to have access to the test environment and data and to work with it in a controlled and secure manner.
The following steps can be taken to identify the test environment and data requirements:
- Identify the hardware and software requirements needed for testing. This may include specific operating systems, databases, web servers, and other components required to run the software being tested.
- Identify the testing tools and frameworks needed to support testing. This may include automated testing tools, performance testing tools, security testing tools, or other tools specific to the type of testing being performed.
- Identify the types of data needed for testing. This may include test data, user data, or production data.
- Identify any data privacy or security requirements that must be followed when working with data.
Once the test environment and data requirements have been identified, it is important to ensure that they are properly set up and configured before testing begins. This may include installing and configuring software, setting test environments, and preparing test data.
4. Creating a test plan
Creating a test plan is an essential step in preparing for ad hoc testing and can help ensure that the testing effort is effective and aligned with the project’s overall goals.
While ad hoc testing is often unstructured and flexible, creating a test plan that outlines the objectives, testing methods, and expected outcomes is still important. The plan should also define each team member’s roles and responsibilities and include a testing schedule.
The following steps can be taken to create a test plan for ad hoc testing:
- Define the testing objectives and goals by identifying the key features or functionality to be tested or the specific quality attributes to be evaluated.
- Define the testing scope, which includes identifying the areas to be tested and areas to be excluded from testing.
- Define the testing approach by finalizing the testing techniques, such as exploratory or scripted testing, and any tools or frameworks used.
- Identify the testing resources like the test team, test environment, and data requirements.
- You must identify the testing milestones, deadlines, and dependencies on other project activities.
Conducting Ad hoc Testing
Here are the vital steps to conduct ad hoc testing:
1. Executing tests
During ad hoc testing, the test team should execute tests without a predefined test plan, relying on their experience, intuition, and creativity to identify defects and issues. They should record their findings as they perform the tests, including steps taken, observations made, and any defects or issues identified.
The test team should focus on specific areas of the software application, which they think might have issues. Also, depending on the nature of the software application and the intended objectives, the test team may adopt different testing approaches, like exploratory testing, usability testing, functional testing, performance testing, or security.
Once the testing approach is defined, the team should start executing tests by performing various actions and observing how the software application responds.
2. Recording and reporting results
As tests are executed, the test team should record the results and report their findings. This includes documenting any defects, issues found, and any positive feedback or suggestions for improvement. It is important to document the steps taken during testing to ensure that results can be reproduced and defects can be retested.
