📝 Core Functional Test Scenarios

Start by verifying the fundamental calculations for each tool in your suite. The table below outlines essential test cases based on standard calculator testing principles258.

👤 User Experience & Interface Tests

A good calculator not only works correctly but is also easy and reliable to use3. Test how your tool behaves from a user’s perspective.

  • Form and Input Validation: Check that input fields only accept valid characters (e.g., numbers, decimal points). Test what happens if a user enters text where a number is expected9.
  • Responsive Design: Open your tool page on various devices (smartphones, tablets, desktops) and different screen sizes. Ensure all buttons, fields, and the results display are readable, accessible, and function correctly on all platforms39.
  • Cross-Browser Compatibility: Test the calculator suite in different web browsers (e.g., Chrome, Firefox, Safari, Edge). Buttons must respond to clicks, and calculations must render correctly in each browser36.
  • Clear and Reset Functions: Verify that the “Clear” (C) or “All Clear” (AC) button properly resets the input fields and results. Test the “Backspace” function to ensure it deletes the last entered digit correctly28.

🧪 Advanced & Negative Test Cases

Go beyond “happy path” testing to ensure robustness8.

  • Boundary Value Testing: If your calculators have defined limits (e.g., a maximum number of digits), test inputs at those boundaries. For example, try entering a very large number to see if it is handled gracefully or causes a display issue28.
  • Error Handling: Intentionally perform invalid operations (like dividing by zero) and confirm a clear error message is shown instead of the tool crashing or displaying a confusing result58.
  • Performance with Rapid Input: Click buttons quickly or perform a sequence of calculations one after the other to check if the tool lags, freezes, or produces incorrect results8.
  • Memory Function Tests (if applicable): If any tool has memory buttons (M+, M-, MR, MC), verify they store and recall values correctly across different calculations8.

💡 A Practical Testing Approach

To implement these tests effectively on your WordPress site:

  • Create a Test Sheet: Document each test case with its steps, input values, and expected outcome. Use a simple table format to track your progress and mark tests as “Pass” or “Fail.”
  • Test in Real-World Conditions: Use your own devices and browsers. Consider using a cloud-based testing platform like BrowserStack to easily test across a wide range of device-browser combinations9.
  • Engage Others: Ask friends or colleagues to use the calculator suite without guidance. Observe where they might get confused or encounter errors—this “exploratory testing” can uncover issues you may have missed36.

🔍 Finding Specific Information

The search results provide an excellent foundation for general calculator testing principles. For aspects not covered in detail, such as specific WCAG accessibility guidelines, you may need to consult dedicated resources on web accessibility.
