Selenium WebDriver with Java - Basics to Advanced and Frameworks - Asserting the Test Cases with Validations

The video tutorial covers common errors related to array index out of bounds in testing scripts, particularly when using data providers. It explains the misconception about array indexing starting from zero and how to fix related errors. The tutorial also introduces the concept of assertions in testing, demonstrating how to use them for validating test results and ensuring that actual outcomes match expected values. The video concludes with an assignment to practice using assertions for validation.

What is a common error encountered when running tests with multiple data sets?

• Divide by zero error

• Null pointer exception

• Syntax error

• Array index out of bounds

What is the starting index of an array in most programming languages?

• One

• Zero

• Negative one

• Two

How can you resolve an 'array index out of bounds' error?

• By using a different data type

• By increasing the array size

• By starting the index from one

• By ensuring indices are within the array size

Why is it important to read error logs carefully?

• To understand the cause of test failures

• To improve code readability

• To find syntax errors

• To increase test coverage

What is the purpose of assertions in testing?

• To print output to the console

• To compare expected and actual outcomes

• To handle exceptions

• To increase test execution speed

Which method is used to compare expected and actual values in TestNG?

• assertEquals

• assertNull

• assertTrue

• assertFalse

What happens if there is a mismatch between expected and actual values in an assertion?

• The script retries the test

• The script continues execution

• The script fails with an error

• The script prints a warning

What is the expected outcome when using assertEquals in TestNG?

• The test passes if the values are different

• The test fails if the values are the same

• The test passes if the values are the same

• The test fails if the values are different

What should you do if you want to check if a navigation bar is present on a webpage?

• Use the isDisplayed method

• Use the sendKeys method

• Use the getText method

• Use the click method

What is the assignment given at the end of the lecture?

• Validate the presence of a navigation bar using assertions

• Write a script to handle exceptions

• Create a new test case

• Optimize test execution time
