What is Exploratory Testing?

Exploratory testing is a highly effective approach to testing software that gives testers the freedom to adapt and experiment on the fly based on their observations of the system and user behaviors. It allows you to unlock the full potential of your testing team and achieve better results by catching issues that rigid and traditional testing approaches might miss.

Why Exploratory Testing?

Exploratory testing lets testers use their skills and know-how to run tests. It helps them find problems quickly while also gathering useful feedback on the product. What sets it apart is the ability for testers to adapt their methods as they go, ensuring thorough coverage and efficient problem-solving.

Is Exploratory Testing always Functional Testing? 

Like many QA definitions, we’ve seen “exploratory testing” used in multiple ways. The term usually refers exclusively to functional testing. In this article, we’ll use “exploratory test” to mean “exploratory functional test.” However, within the Global App Testing product, you can ask our testers to focus on multiple kinds of issues, including functional, localization, and usability issues.

We call this an “audit” (our launchpad doesn’t refer to it as “exploratory testing” for this reason), and you can easily select it when you launch a test.

When is Exploratory Testing done?

At the core of all product and QA decisions lie the needs of the business. To enhance the durability of your quality assurance procedures, it is essential to incorporate exploratory testing as an indispensable factor. You might opt for exploratory testing if:

  • Your critical test cases have been executed, and you're not using exploratory tests as a substitute for absolute legal or safety requirements.
  • Exploratory testing proves more effective in uncovering bugs compared to other testing methods. For instance, it may reveal a higher number of high or critical-importance bugs than your predefined test cases.
  • You rely heavily on repetitive test cases and are concerned about their ability to detect all potential bugs in your product.
  • You wish to explore 'edge cases' within your software, such as scenarios where certain user inputs or conditions may cause unexpected behavior. For example, individuals with the Korean surname 'Le' encounter issues with forms that require a minimum three-letter surname. Exploratory tests excel in identifying these edge cases and potential vulnerabilities.
  • You lack written test cases and prefer to test your product without them (note that GAT can assist in test case creation if needed).

We don’t recommend exploratory testing as a totalized test strategy. It’s a great way to complement test cases, and we’d say you really need both – the first to ensure you have coverage planned for your whole system and the second to add extra robustness to that process.

Example of an Exploratory test

ConnectX, a fictional social media platform, initiated an exploratory test to ensure the quality and reliability of its posting functionality. The decision to conduct this test was made during the development phase of a major app update, ensuring comprehensive coverage across regression and new feature testing.

During the exploratory test, the assigned tester logged into her test account on ConnectX and navigated to the home/feed page. The tester systematically explored the options available for creating a new post and tested various combinations of text and media content. Special attention was given to how the app handled different scenarios, such as uploading images, videos, or links, and the accuracy of privacy settings.

The tester's exploration uncovered several bugs, including:

  • Instances where uploaded images failed to display correctly on Android phones when held horizontally.
  • Privacy settings are not being properly applied, allowing private email addresses of other users to be visible when inspecting feed posts.

ConnectX promptly addressed these issues before releasing the app update to their users, resulting in an enhanced user experience. These identified bugs were crucial as they were not covered in the test cases and would have remained undetected through a test-case-only approach.

Types of Exploratory Testing

Exploratory testing offers different approaches:

  • Freestyle: Testers explore the app without strict rules, good for quick checks or familiarizing with the app.
  • Strategy-Based: Experienced testers use various techniques to ensure thorough testing.
  • Scenario-Based: Testing based on specific scenarios provided by users or created by the team.
  • Collaborative: Testers work together, sharing insights to uncover different types of issues.
  • Charter-Based: Testers follow a predefined plan outlining what to test.
  • Timing-Boxed: Testers have a set time limit to find as many serious bugs as possible.

Exploratory Testing: How it works

Exploratory testing follows similar steps to a regular test consisting of:

1. Product learning 

Specialized and B2B applications may require some education before an exploratory test can be effective. At Global App Testing, we facilitate this process through instructional sessions, utilizing our comprehensive materials and framework acquired during our 100-day onboarding to ensure testers reach a minimum competency level. Additionally, we encourage testers to engage in a play period within the application, allowing them to familiarize themselves with the product firsthand. Typically, both approaches are employed to ensure thorough understanding and proficiency.

2. Outcome learning 

Testers should be aware of the desired outcomes, whether it's detecting flaws in early iterations or ensuring resolved bugs are not reintroduced.  Again, at Global App Testing, we equip testers with the necessary materials and knowledge to streamline their bug-reporting process, minimizing unnecessary noise.

3. Execution

Testers have the freedom to conduct tests as soon as they are written or requested. They observe, probe, and explore the application or website, compiling and reporting results through appropriate methods. This approach encourages an unconstrained search for bugs and rewards both the product and the tester.

4. Reiterate

Each round of exploratory testing provides new data for the incentivized testers as you accept or reject the bugs and tag their severity. This means that as you keep undertaking exploratory tests, your exploratory tests should become more effective at identifying issues in your software.

Exploratory testing within agile 

Exploratory testing is difficult to automate, which makes Agile development with an exploratory test embedded into the sprint cycle a challenge. However, Global App Testing offers a solution by providing a 48-hour turnaround for exploratory tests (excluding very large tests such as Ts & Cs) through crowd testing. While this isn't a concern with us, it remains a common challenge for businesses in general.

Let’s look at the benefits of Exploratory Testing in Agile development:

  • Rapid feedback: Provides swift insights during early development stages.
  • Comprehensive bug detection: Uncovers a diverse range of bugs.
    Inclusive testing: Can be conducted by developers, testers, designers, and stakeholders without predefined scripts.
  • Ideal for iterative development: Testing new features complements the iterative coding process, while automation focuses on regression and compatibility.
  • Adaptive to changing requirements: Particularly effective when project requirements are volatile, enabling quick validation of new requirements within tight deadlines for actionable results.
