Logging and Reporting in Selenium

When test cases are executed, test reports are examined by testers who want to find out about failures and how the tests were executed. However effective logging in the code is required if they want to find out why the errors occurred.

Let's talk about logging and reporting separately and why they are crucial in Selenium.

What is logging?

The term "logging" describes the procedure of recording every aspect of the testing process. This includes information logs on how the applications may or may not have operated or been implemented. It provides an accurate evaluation of application performance, including any problems that might have arisen during testing.

Logging is primarily used to preserve a record of the testing procedure. Therefore, the testing team can analyze the results and assess if the application satisfies the quality. The goal is to make a post-execution examination of application errors and flaws available.

An effective logging framework will provide a clear knowledge of how the test suite is run. One such logging framework that assists in capturing data in the form of logs or log files is Log4j in Selenium.

Log4j in Selenium

Selenium uses the Java-based logging framework Log4j. By providing details about everything that occurs throughout the execution of the test, it offers a simple method for logging. Insight into potential errors during application execution or automation is also provided by Log4j.

Components of Log4j

The three components of the Log4j logging framework are as follows.


All the information required to be created by the framework is present in the logger Log4j. Its logger class and log-level methods can be used to fully comprehend how it operates.

Based on the action being taken, log severity varies.Log4j offers 5 different severity log-level options. Their names are ALL, ERROR, WARN, DEBUG, INFO, and FATAL.


Now that it specified what the logs will be, appenders will choose what will happen to those logs. Log events will be sent to the desired folder. For Log4j, there are four primary categories of appenders. FileAppender, ConsoleAppender, RollingFileAppender, and DailyRollingFileAppender are each of them.


The layout offers several options for formatting logs. It determines how log messages will be formatted. One can utilize a variety of layouts for log messages. The main three of them are XML Layout, Pattern Layout, and HTML Layout.

Why Use Log4j in Selenium?

Selenium is a wonderful application for using Log4j as a logging system. By maintaining logs, its robust design and distinct components make it simpler to track, monitor, and debug automation tests. , Selenium uses the Log4j logging framework for the following reasons:

The Log4j logging framework may make application debugging simple. It records every step of the testing procedure in detail, including what was tested, who tested it when it was tested, and the test cycle's outcomes. Furthermore, it is simpler to categorize information by categories when there are various log levels.

The open-source logging framework can assist with troubleshooting problems that develop during testing in various contexts. This ultimately assists in identifying the underlying causes of problems and taking appropriate action to fix them by looking at the logs. Thus, facilitating the QA team's ability to prioritize issues. Especially, those to fix quickly before release, hence enhancing application performance.

It is more accessible for quicker debugging because the setup is simple and cost-free. It is also simpler to use and configure log4j in Selenium with three components and clear usage.
