Sample questions
Excerpts from this guide's answers.
- Q1. What is Selenium WebDriver, and how does it work?
- Selenium WebDriver is a W3C-standard API for automating browsers.
- Q42. Why should implicit and explicit waits not be mixed?
- Combining them can produce unpredictable wait times, because an explicit wait's polling calls findElement, which itself waits implicitly.
- Q71. Why is TestNG popular for Selenium Java frameworks?
- TestNG provides flexible annotations, groups, dependencies, data providers, parallel execution configured in XML, listeners, retry analyzers and soft assertions.
