Selenium Web Application Evaluation Strategies 3

Question 1

Which strategy is best for evaluating a web application's behavior across multiple browsers using Selenium?

Accepted Answer

Use Selenium Grid or a cloud provider like Sauce Labs to parallelize cross-browser testing

Answer

Selenium Grid and cloud providers enable parallel cross-browser execution, making comprehensive browser coverage practical and time-efficient.

Question 2

When evaluating page performance metrics with Selenium, how can you capture Navigation Timing API data?

Accepted Answer

Execute JavaScript with driver.executeScript() to access window.performance.timing

Answer

The Navigation Timing API is accessible via JavaScript, and driver.executeScript() retrieves the timing object from the browser's window context.

Question 3

To evaluate the correct rendering of responsive breakpoints in a web application, which Selenium technique is used?

Accepted Answer

Use driver.manage().window().setSize() to simulate different viewport sizes

Answer

Setting the browser window size via Selenium's window management API simulates different viewport widths for responsive layout evaluation.

Question 4

Which approach is most reliable for evaluating the state of a checkbox in a Selenium test?

Accepted Answer

Use element.isSelected() to determine checked state

Answer

The isSelected() method directly returns the boolean checked state of checkboxes, radio buttons, and select options.

Question 5

When evaluating file upload functionality in a Selenium test on a web application, what is the correct approach?

Accepted Answer

Send the file path as text to the hidden file input element using sendKeys()

Answer

Sending the local file path directly to the file input element using sendKeys() bypasses the OS dialog and works reliably across browsers.
