What Is Exploratory Testing?

 

Exploratory testing is a simultaneous process of learning, test design, and execution. Unlike scripted testing, it doesn’t rely on predefined test cases. Instead, testers use their intuition, domain knowledge, and creativity to uncover defects by actively exploring the application.

It’s like being a detective in the software—following clues, testing hypotheses, and adapting your strategy in real time.

🕰️ When Should You Use It?

Exploratory testing is ideal when:

  • ✅ Requirements are incomplete or evolving
  • ✅ Time is limited for formal test case creation
  • ✅ You need to test usability, edge cases, or real-world user behavior
  • ✅ You want to complement automated or scripted testing with human insight

Especially useful in Agile environments, early-stage prototypes, or field tools where user behavior is unpredictable.

🎯 Why Should You Use It?

  • Uncovers hidden bugs missed by scripted tests
  • Simulates real user behavior, revealing usability issues
  • Adapts to change quickly, perfect for dynamic systems
  • Encourages tester creativity and ownership
  • Boosts test coverage in areas not covered by formal scripts

For humanitarian tools, this method helps ensure that apps and protocols behave reliably in unpredictable field conditions.

🛠️ How to Use It (Step-by-Step)

  1. Define a Test Charter
    A short mission like: “Explore login functionality for edge cases.”
  2. Time-box the Session
    Allocate 60–90 minutes per session to stay focused.
  3. Explore and Document
    Interact with the system freely. Log bugs, observations, and test paths.
  4. Debrief and Analyze
    Share findings with the team. Discuss what worked, what didn’t, and what to test next.
  5. Iterate
    Refine your approach based on what you learned.

🌍 Real-World Examples

1. Humanitarian Field App Testing

Imagine a mobile app used by Save the Children staff to report child protection incidents. You perform exploratory testing by:

  • Simulating poor network conditions
  • Entering multilingual data (e.g., Bengali-English mix)
  • Navigating without GPS permissions
  • Testing offline sync and data recovery

This uncovers issues like broken form validation, missing translations, or sync failures—critical in field use.

2. E-Commerce Platform

A QA tester explores:

  • Adding/removing items from cart
  • Applying multiple coupon codes
  • Leaving mandatory fields blank during checkout
  • Trying to purchase out-of-stock items

They discover bugs like incorrect discount calculations or checkout crashes—issues that scripted tests missed.

What is an SDET? – Roles, Responsibilities, and Career Path

Introduction The field of software testing has evolved significantly, and with the rise of automation, the Software Development Engineer in Test (SDET) role has become crucial. SDETs are technical testers with strong programming skills who ensure software quality through test automation and continuous integration. But what does an SDET really do? Let’s dive in.   Key Responsibilities of an SDET An SDET wears multiple hats—part developer, part tester, and part automation engineer. Their primary responsibilities include: Developing test automation frameworks for functional and regression testing. Writing automated test scripts to validate application functionality. Collaborating with developers to ensure testability of code. Implementing CI/CD pipelines with automated testing for continuous deployment. Conducting performance, security, and API testing to enhance software robustness. Required Skills for an SDET To excel as an SDET, you need a mix of technical and so...

Keys.RETURN vs Keys.ENTER in Selenium: Are They Really the Same?

When you're automating keyboard interactions with Selenium WebDriver, you're bound to encounter both Keys.RETURN and Keys.ENTER . At a glance, they might seem identical—and in many cases, they behave that way too. But under the hood, there’s a subtle, nerdy distinction that can make all the difference when fine-tuning your test scripts. In this post, we’ll break down these two key constants, when to use which, and why understanding the difference (even if minor) might give you an edge in crafting more accurate and resilient automation. 🎹 The Subtle Difference On a standard physical keyboard, there are typically two keys that look like Enter: Enter key on the numeric keypad. Return key on the main keyboard (near the letters). Historically: Keys.RETURN refers to the Return key . Keys.ENTER refers to the Enter key . That’s right—the distinction comes from old-school typewriters and legacy keyboard design. Return meant returning the carriage to the beginning ...

Regression Testing vs. Sanity Testing: Detailed Explanation with Example

  Regression testing and sanity testing are both essential software testing techniques, but they serve different purposes in ensuring software stability after modifications. Regression Testing Definition: Regression testing is a comprehensive testing approach that ensures recent code changes do not negatively impact the existing functionality of an application. It involves re-running previously executed test cases to verify that the software still works as expected after modifications such as bug fixes, feature additions, or updates. Key Characteristics: Scope: Covers the entire application. Purpose: Ensures that new changes do not break existing functionality. Execution Time: Time-consuming due to extensive testing. Test Cases: Uses a large set of test cases. Automation: Often automated for efficiency. Depth: In-depth testing of all functionalities. When Used: After major updates, bug fixes, or new features. ...
