Ad Hoc Testing: Everything You Need To Know

Every software needs to be tested before it is released to the public. This ensures that the software is reliable and performs as expected. There are various methods to test software, such as unit testing and integration testing. Ad Hoc testing is another software testing technique that can be used to ensure software quality.

What is ad hoc testing?

Ad hoc testing is one software testing that can help with quality assurance. It is an informal testing method to find software defects and problems quickly. The ad hoc software testing method does not follow formal procedures but relies on testers’ experience and intuition.

Think of ad hoc testing as a spur-of-the-moment testing service that finds software defects before release.

Ad hoc testing can be conducted at any stage of the development cycle and testing technique. However, it is usually done after all other tests have been completed. It is a type of testing that allows testers to explore software in an unstructured way, making it suitable for software development projects with tight deadlines.

Key advantages of ad hoc testing

Here are the key advantages of ad hoc testing:

It is cost and time efficient

Ad hoc software testing is a quick method that helps developers find program defects quickly. This means software projects can be released faster and at a lower cost.

It is flexible

As stated earlier, ad hoc software testing and methods do not follow formal procedures. This means software testers can use their confidence with ‘error-guessing’ to find defects.

It is useful for software projects with tight deadlines

Ad hoc testing can be performed quickly and efficiently, making it an excellent option for software development projects with tight timelines.

It discovers bugs that aren’t recognized with other formal software testing methods

Ad hoc software testing can uncover bugs not found during other tests. This means developers can release the program with fewer or no defects.

It enables developers and testers to work together

Ad hoc testing allows software teams to work together(buddy testing). As there are no documented test cases, testers and developers can share ideas, examine defects and collaborate efficiently on fixing issues.

No planning or documentation required

Ad hoc software testing does not require developers to plan software tests or documentation. This saves them time and effort, allowing projects to be completed faster.


Disadvantages of ad hoc testing

While ad hoc testing can be beneficial in certain software development situations, there are some drawbacks to using this method. Here are some of the disadvantages of ad hoc software testing:

It is not suitable for complex software projects

Ad hoc software testing is not suitable for complex software development projects. This software testing method makes it difficult to track defects, making software projects with complex software requirements difficult to manage.

It can be difficult to reproduce software defects

Since ad hoc software testing does not have written test cases, it can be difficult to reproduce software defects. This means software teams may be unable to track defects and solutions efficiently.

It requires experienced software testers

Ad hoc software testing requires software testers with extensive experience. Thus, finding such talents can be challenging for organizations.

It has little to low accountability

Since software teams do not have documented software tests, developers and testers may be less accountable for errors in the program. This can make software projects difficult to manage.

Types of ad hoc testing methods

There are three common ad hoc software testing methods employed in software development projects:

Monkey testing

This software testing method includes testers randomly inputting data into the software application and trying to damage the software.

Buddy testing

This software testing method involves developers and testers working together to test software applications. Both can provide valuable feedback to software teams.

Pair testing

This ad hoc testing method involves two testers working together on a single program. While one software tester executes the testing, the other records and takes notes on the defects.

Some might confuse pair testing and buddy testing; however, they are two distinct software testing methods. One needs someone from the development and testing teams present for buddy testing. For pair testing, one would only need two people on the QA team, but they should ideally have different levels of expertise.

When to avoid ad hoc testing

While ad hoc software testing can be useful in software development projects, it should be avoided in certain scenarios. Here are some scenarios where ad hoc software testing should be avoided:

Testers don’t have the expertise: Ad hoc software testing needs software testers with in-depth details and testing experience. Thus, software teams should avoid using ad hoc software testing if the testers do not have the necessary expertise.

UI testing: If the software is being tested to check user navigation and usability, software teams should avoid ad hoc software testing. UI software testing requires detailed software tests and documentation, making ad hoc software testing unsuitable for this software testing task.

High-risk software: One should avoid ad hoc software testing for projects involving high-risk software development, such as for programs developed for medical devices and mission-critical operations. Such software projects require structured tests, making ad hoc testing unsuitable.
