Selenium Testing Framework Case Studies & Practical Application 4

Question 1

A Selenium test suite runs against multiple browsers (Chrome, Firefox, Edge). Currently the browser is hard-coded in a base class. The best architectural change is:

Accepted Answer

Read the browser type from a configuration file or environment variable

Answer

Reading browser type from configuration or environment variables allows the same tests to run against any browser without code changes.

Question 2

After a sprint, 30% of automated tests are failing due to UI redesign (locators changed). To prevent this recurring cost, the team should:

Accepted Answer

Implement data-testid attributes with developers and update locators once per change

Answer

Stable data-testid attributes agreed upon with developers create resilient locators that don't break with styling or layout changes.

Question 3

A test must verify that a search returns exactly 10 results on the first page. The results load asynchronously. The most reliable assertion approach is:

Accepted Answer

Wait for the result count element to appear, then assert the list size

Answer

Waiting for a specific element that signals results have loaded before asserting the count ensures the DOM is stable.

Question 4

A team wants to run Selenium tests on mobile browsers. The most appropriate tool to extend their existing Selenium setup is:

Accepted Answer

Appium, which extends the WebDriver protocol for mobile

Answer

Appium implements the WebDriver protocol for mobile platforms, allowing teams to reuse Selenium skills and some code for mobile browser testing.

Question 5

A Selenium test navigates to a page with infinite scroll. To test that items load when scrolling, the best approach is:

Accepted Answer

Use JavascriptExecutor to scroll to the bottom and wait for new elements

Answer

Scrolling via JavascriptExecutor (window.scrollTo or element.scrollIntoView) triggers the scroll events that activate infinite scroll loaders.
