Logging test steps in Selenium Java - Practice Problems & Coding Challenges

Challenge - 5 Problems

💻 Command Output

intermediate

What is the output of this Selenium Java logging code?

Consider the following Selenium Java code snippet that uses java.util.logging.Logger to log test steps. What will be printed to the console?

Selenium Java

import java.util.logging.Logger;
import java.util.logging.Level;

public class TestLogging {
    private static final Logger logger = Logger.getLogger(TestLogging.class.getName());

    public static void main(String[] args) {
        logger.setLevel(Level.INFO);
        logger.info("Starting test execution");
        logger.warning("This is a warning message");
        logger.severe("This is an error message");
    }
}

A

INFO Starting test execution
WARNING This is a warning message
SEVERE This is an error message

B

INFO: Starting test execution
WARNING: This is a warning message
SEVERE: This is an error message

C

Starting test execution
This is a warning message
This is an error message

D Error: Logger not initialized

💡 Hint

Look at the default format of java.util.logging.Logger output.

The java.util.logging.Logger prints messages with the level name followed by a colon and the message. So info, warning, and severe messages appear with their level labels.

❓ Configuration

Which configuration enables detailed logging for Selenium WebDriver in Java?

You want to enable detailed logging for Selenium WebDriver actions in your Java test. Which option correctly sets the logging level to show all messages?

A Logger.getLogger("org.selenium").setLevel(Level.WARNING);

B Logger.getLogger("selenium").setLevel(Level.SEVERE);

C Logger.getLogger("webdriver").setLevel(Level.OFF);

D Logger.getLogger("org.openqa.selenium").setLevel(Level.ALL);

💡 Hint

The Selenium WebDriver logs are under the 'org.openqa.selenium' package.

To see all Selenium WebDriver logs, set the logger for 'org.openqa.selenium' to Level.ALL. Other options either use wrong package names or levels that suppress logs.

🔀 Workflow

advanced

What is the correct order to add logging to Selenium test steps?

Arrange the steps in the correct order to add logging for Selenium test steps in Java.

A 1,2,3,4

B 2,1,3,4

C 1,3,2,4

D 3,1,2,4

💡 Hint

Think about initializing logger before using it and logging before and after actions.

First, create the Logger instance. Then log the start, perform actions, and finally log completion.

❓ Troubleshoot

advanced

Why does this Selenium Java test not show any log output?

Given this code snippet, why might no log messages appear on the console? import java.util.logging.Logger; public class Test { private static final Logger logger = Logger.getLogger(Test.class.getName()); public static void main(String[] args) { logger.info("Test started"); } }

A The default logging level is higher than INFO, so INFO messages are not shown

B The main method is not executed

C The code is missing a call to logger.start()

D Logger is not initialized properly, causing no output

💡 Hint

Check the default logging level for java.util.logging.Logger.

By default, the logging level is set to INFO or higher, but sometimes the console handler level is set to WARNING, so INFO messages are not shown unless the handler level is lowered.

✅ Best Practice

expert

Which is the best practice for logging Selenium test steps in Java?

Choose the best practice for logging test steps in Selenium Java tests to ensure clear, maintainable logs.

A Avoid logging to keep tests fast and clean

B Log every single WebDriver command at SEVERE level to catch all errors

C Use descriptive messages with test step details and log at appropriate levels (INFO, WARNING, SEVERE)

D Use System.out.println for all logging to simplify output

💡 Hint

Think about clarity and usefulness of logs for debugging.

Good logging uses descriptive messages and appropriate log levels to help understand test flow and issues. Logging everything as SEVERE or using System.out.println is not recommended.
