Answer Explanations
| # | Question | Correct Answer(s) | Explanation |
|---|---|---|---|
| 1 | Difference between single (/) and double (//) slash in XPath? | Single (/) starts from root, double (//) searches anywhere | A single slash (/) selects nodes from the root, while a double slash (//) allows selection from anywhere in the document. |
| 2 | Which is NOT a Selenium limitation? | Selenium IDE supports all browsers | Selenium IDE mainly supports Firefox and Chrome, but not all browsers. Other limitations include web-only testing, no built-in image comparison, and reliance on external tools. |
| 3 | Difference between typeKeys() and type()? | typeKeys() simulates keystrokes, type() pastes full text | typeKeys() mimics real keyboard inputs, while type() pastes the full string at once. |
| 4 | Key difference between verify and assert? | Assert stops execution on failure, Verify continues | assert forces test execution to stop if a condition fails, whereas verify logs failures and continues execution. |
| 5 | Why choose Selenium over QTP? | All of the above | Selenium is open-source, supports multiple OS and browsers, and is designed for web testing, while QTP (now UFT) is paid and supports desktop apps. |
| 6 | Does the Same Origin Policy restrict Selenium tests? | Yes | The Same Origin Policy prevents scripts from interacting with elements across different domains to enhance security. |
| 7 | Can Selenium handle Windows pop-ups? | No | Selenium interacts with web elements only; Windows-based pop-ups require tools like AutoIt or Robot Framework. |
| 8 | How to pass login credentials in a URL? | http://username:password@url | This format embeds credentials within the URL to bypass basic authentication popups. |
| 9 | When should Selenium Grid be used? | Run tests on different browsers & machines in parallel | Selenium Grid allows parallel execution across multiple machines and browsers, improving test efficiency. |
| 10 | Which statement about setSpeed() and sleep() is incorrect? | sleep() takes milliseconds, setSpeed() takes a string | sleep() accepts milliseconds as a parameter, but setSpeed() takes a numerical delay value, not a string. |
