This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this course, you will gain the essential skills needed to effectively use Gatling for API stress testing. You will learn to install and configure Gatling, create scripts, run performance tests, and monitor the results. By the end of the course, you’ll be able to design load simulations and use Gatling’s powerful tools to perform comprehensive stress tests on your API services. The course will guide you through the installation of Gatling, setting up your development environment, and writing your first Gatling script from scratch. You’ll get hands-on experience with key features like the Gatling recorder, session variables, and debugging tools. Throughout the lessons, you’ll build up your skills by using real-world scenarios, such as simulating users on an API, managing response data, and testing under varied loads. As you progress, you’ll learn to handle different types of performance tests like ramping up users, using feeders to inject test data, and authenticating requests. The course concludes with a deep dive into integrating Gatling with Continuous Integration tools like Jenkins and Travis, which will enhance your automated testing capabilities. This course is perfect for software developers, QA engineers, and DevOps professionals who are looking to enhance their API testing and load testing skills. A basic understanding of software development and APIs is recommended. No prior experience with Gatling is necessary.

Syllabus

Introduction to Gatling

In this module, we will introduce you to the Gatling stress testing tool, highlighting its key features and optimal scenarios for its integration. You will gain an understanding of when and how Gatling can be effectively implemented in your projects to ensure thorough system testing.

Gatling Installation and Using the Gatling Recorder

In this module, we will guide you through the installation of Gatling and demonstrate how to use the Gatling Recorder for capturing user journeys. You will learn how to record, convert, and execute Gatling scripts to perform effective stress testing on your systems, ensuring a hands-on approach to mastering the tool.

Dependency Installation and Gatling Project Configuration

In this module, we will focus on setting up the necessary dependencies and configuring your Gatling project. You will learn how to establish a development environment, configure a project using Gatling, and write your first custom Gatling script to perform stress tests effectively.

Gatling Script Fundamentals

In this module, we will dive into the core fundamentals of writing Gatling scripts. You will learn how to manage pauses, check response codes and bodies, extract dynamic data, and debug your scripts for effective performance testing. Additionally, we’ll explore optimizing your code, using loops, and incorporating authentication to create realistic and efficient load tests.

Gatling Feeders

In this module, we will explore how to enhance your Gatling tests with feeders. You'll learn to use CSV feeders for data injection, create custom feeders to generate dynamic data programmatically, and integrate templating for structured request payloads. These techniques will enable you to perform more sophisticated and data-driven performance tests.

Load Simulation Design

In this module, we will cover the essential techniques for load simulation in Gatling. You'll learn how to create basic load tests, implement ramp-up strategies to simulate growing user traffic, and execute fixed-duration tests to analyze application performance under sustained load. These methods will help you better understand your application's scalability and stability.

Execution from the Command Line

In this module, we will explore how to run Gatling tests directly from the command line. You'll learn the necessary command syntax, how to execute scripts independently, and how to use runtime parameters to adjust test configurations like user load and duration for greater flexibility.

Putting it all Together

In this module, we will consolidate everything you’ve learned by tackling a final challenge. You’ll integrate all the concepts covered throughout the course into a complete Gatling script. We will guide you through the solution, demonstrating how to structure, refine, and optimize your script to achieve successful performance testing.

Test Monitoring and Reporting

In this module, we will explore the essential aspects of monitoring and reporting in Gatling. You will learn how to oversee test executions and analyze the test results reports generated by Gatling. This will enable you to assess the effectiveness of your tests and optimize application performance based on the insights provided.

Gatling with Continuous Integration Tools

In this module, we will focus on integrating Gatling with popular continuous integration tools, such as Jenkins and Travis CI. You will learn how to set up GitHub repositories, configure Jenkins to run Gatling tests, and trigger tests with runtime parameters. Additionally, we’ll explore adding assertions to automate build failures and setting up environment variables in Travis for seamless CI pipeline integration.
