WebDriver setup (ChromeDriver) in Selenium Java - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is ChromeDriver in Selenium?

ChromeDriver is a separate executable that Selenium WebDriver uses to control the Chrome browser. It acts as a bridge between Selenium commands and the Chrome browser.

beginner

How do you set up ChromeDriver in a Selenium Java project?

You download the ChromeDriver executable matching your Chrome version, set its path in your code using System.setProperty("webdriver.chrome.driver", "path/to/chromedriver"), then create a new ChromeDriver instance.

intermediate

Why must the ChromeDriver version match the Chrome browser version?

Because ChromeDriver controls the browser using specific commands that depend on the browser's internal structure. Mismatched versions can cause failures or unexpected behavior.

beginner

What is the purpose of System.setProperty in ChromeDriver setup?

System.setProperty tells Java where to find the ChromeDriver executable on your computer so Selenium can launch and control the Chrome browser.

beginner

Show a simple Java code snippet to launch Chrome browser using Selenium WebDriver.

System.setProperty("webdriver.chrome.driver", "path/to/chromedriver"); WebDriver driver = new ChromeDriver(); driver.get("https://example.com");

What does ChromeDriver do in Selenium testing?

A Manages test reports

B Controls the Chrome browser to run tests

C Compiles Java code

D Is a browser itself

ChromeDriver controls the Chrome browser by receiving commands from Selenium WebDriver.

Which Java method sets the path to ChromeDriver executable?

A System.setProperty

B WebDriver.setPath

C ChromeDriver.init

D DriverManager.setup

System.setProperty is used to specify the location of the ChromeDriver executable.

What happens if ChromeDriver version does not match Chrome browser version?

A Tests run faster

B No effect on tests

C Tests may fail or behave unexpectedly

D Browser updates automatically

Version mismatch can cause communication errors between ChromeDriver and the browser.

Which of these is a correct way to start ChromeDriver in Java?

A WebDriver driver = new ChromeDriver("path");

B ChromeDriver.start("path");

C DriverManager.setDriver("chrome");

D System.setProperty("webdriver.chrome.driver", "path"); WebDriver driver = new ChromeDriver();

You must set the system property first, then create a ChromeDriver instance.

Where do you get the ChromeDriver executable?

A From the official ChromeDriver website

B From the Chrome browser settings

C From Selenium IDE

D From Java SDK

ChromeDriver must be downloaded from its official site matching your Chrome version.

Explain the steps to set up ChromeDriver for Selenium WebDriver in Java.

Think about what you need before running tests on Chrome.

Why is it important to keep ChromeDriver and Chrome browser versions compatible?

Consider how devices need matching software to work well together.
