Selenium WebDriver with Java - Basics to Advanced and Frameworks - How to Write Global Parameters with Java Code

This video tutorial explains how to manage global environmental values in Java test cases by using properties files. It covers creating a properties file, reading and modifying its values at runtime, and writing back updated values. The tutorial demonstrates using Java classes like Properties, FileInputStream, and FileOutputStream to handle these tasks, providing a practical approach to managing test environments and configurations.

What is the main purpose of setting global environmental values in Java test cases?

• To make tests more complex

• To reduce the number of test cases

• To increase the speed of test execution

• To ensure all tests run in the same environment

Why is it important to use global values in test frameworks?

• To increase the complexity of the framework

• To ensure consistency across tests

• To make tests more difficult

• To reduce the number of test cases

What file extension is used for properties files in Java?

• Using getValue() method

• Using readValue() method

What method is used to change a property value at runtime in Java?

• updateProperty()

• modifyProperty()

• changeProperty()

• setProperty()

What happens to the properties file when a property value is changed at runtime?

• The file is deleted

• The file remains unchanged

• A new file is created

• The file is automatically updated

Which class is used to write back updated values to a properties file?

What is the purpose of the store() method in Java's Properties class?

• To encrypt values in a file

• To read values from a file

What is the difference between load() and store() methods in Java's Properties class?

• Both methods write values

• Both methods read values

• load() writes values, store() reads values
