Master Apache JMeter - From Load Testing to DevOps

By: Antonio Gomes Rodrigues, Bruno Demion (Milamber), Philippe Mouawad

Overview of this book

Load tests help identify the maximum number of requests a software system can handle. One popular open source tool for load testing is JMeter. By leveraging the features and capabilities of JMeter, you can perform extensive load testing and fix issues in your application before they become problematic. This book is written by JMeter developers and begins by discussing the whole process, including recording a script, setting it up, and launching it, enabling you to almost immediately start load testing. You'll learn the best practices that you must follow while designing test cases. You'll also explore the different protocols offered by JMeter through various real-world examples. Finally, you'll see how to integrate JMeter into the DevOps approach and create professional reports. You'll discover ways to use the eco-system of JMeter to integrate new protocols, enrich its monitoring, and leverage its power through the use of the cloud. By the end of this book, you'll know all that's needed to perform comprehensive load testing on your applications by using all the best practices and features of JMeter.

Setup with JMeter


Since JMeter is a Java program, access to a database is done using the JDBC protocol.

The first thing to do is put the JDBC driver in the JMeter classpath if that has not already been done.

The two simplest solutions to this are:

  • Dropping the .jar driver file in JMETER_HOME/lib/
  • Using the user.classpath property to reference the driver JAR

Once this is done, you must configure the connection to the database with the JDBC Connection Configuration element.

This will allow us to configure the connection string for our database (including the URL, port, connection ID, password, and so on):

Figure 9.5: JDBC connection configuration

This element is composed of four parts, named as follows:

  • Variable Name Bound to Pool: This name will further be used in JDBC Requests.
  • Connection Pool Configuration.
  • Connection Validation by Pool.
  • Database Connection Configuration.

The property names are very self-explanatory, so we will not dwell any...
