Question

What is System.setProperty() in selenium?

Answer

The setProperty method requires two parameters, property name, and value.

System.setProperty(""propertyName"", ""value"");

As the name suggests, it is used to set properties to the browser. The propertyName indicates the name of the browser-specific driver and the value points to the path to that browser driver.

ex: System.setProperty(""webdriver.chrome.driver"", ""E://chromedriver.exe"");

This will initialise Chrome browser and later it will be launched by WebDriver reference
