button breaker Interview Questions and Answers

1. What is a button breaker, in the context of software testing?

   • Answer: A "button breaker" is an informal term for a software tester whose primary focus is on finding bugs by rigorously testing the functionality of buttons, links, and other interactive elements within a user interface (UI). They systematically click and interact with every button to discover unexpected behaviors, crashes, or errors.

2. Describe your testing methodology as a button breaker.

   • Answer: My approach involves methodical exploration of all UI elements. I begin by identifying all clickable elements, then systematically test each one under various conditions (different browsers, operating systems, input values, network states). I document each test case, the expected outcome, and the actual result, meticulously recording any deviations or unexpected behavior.

3. What tools do you use to assist your button-breaking efforts?

   • Answer: I leverage browser developer tools to inspect elements, network requests, and console logs. I also use automation tools like Selenium or Cypress for repetitive testing, allowing me to focus on more complex scenarios and edge cases. Test management tools like Jira or TestRail help track my findings and progress.

4. How do you prioritize which buttons to test first?

   • Answer: I prioritize based on risk and criticality. Buttons that lead to core application functionality or sensitive data handling are tested first. I also consider buttons used frequently or those involved in critical user flows.

5. How do you handle situations where a button's functionality is unclear or undocumented?

   • Answer: I would investigate the button's context, trying to understand its intended purpose from the surrounding UI elements and user flows. If still unclear, I document my findings and escalate to the development team for clarification. I would then proceed with testing based on my best educated guess, documenting the assumptions made.

6. Describe a time you found a critical bug by focusing on button testing.

   • Answer: (This answer should be tailored to your own experience. An example: "In a previous role, I discovered a security vulnerability by exhaustively testing 'submit' buttons on a payment form. I found that under specific conditions, the form failed to properly encrypt sensitive data, creating a potential risk of data breaches.")

7. How do you deal with buttons that have unexpected or inconsistent behavior across different browsers?

   • Answer: I meticulously document the inconsistencies across browsers, noting the specific browser versions and operating systems where the discrepancies occur. I provide detailed steps to reproduce the issue and screenshots for each case. This information is crucial for developers to debug and fix cross-browser compatibility issues.

8. How do you test buttons that trigger asynchronous operations (e.g., AJAX calls)?

   • Answer: I use browser developer tools to monitor network requests and ensure the server responds correctly. I check for appropriate loading indicators or feedback mechanisms to the user. I also verify that the application updates its state appropriately after the asynchronous operation completes.

9. Explain the difference between positive and negative testing of buttons.

   • Answer: Positive testing verifies that buttons function as expected under normal conditions. Negative testing involves intentionally providing invalid inputs or performing actions outside the expected usage to ensure the system handles errors gracefully and prevents unexpected behavior.
