Stress Testing APIs with Gatling and Scala Online Course
Stress Testing APIs with Gatling and Scala Online Course
This online course will guide you through mastering Gatling, an open-source tool for load-testing web applications. Starting with Gatling installation, you will learn to use the Gatling Recorder to capture user journeys and generate scripts effortlessly. You’ll execute your first Gatling script and dive into testing with response code checks, data extraction, and debugging session variables. The course covers advanced topics like looping HTTP calls, authentication, and working with CSV feeders. You will also explore load simulations, running Gatling from the command line, and configuring runtime parameters. By the end, you will be equipped to perform effective load tests, monitor test executions, and integrate Gatling into CI/CD pipelines for optimized performance.
Key Benefits
- Develop core Gatling script functionality from the ground up, building a strong foundation in load testing.
- Design and implement comprehensive load-test scenarios within your Gatling scripts, and execute them efficiently from the command line.
- Leverage Gatling's robust Domain Specific Language (DSL), which simplifies the testing process and removes the requirement for in-depth Scala knowledge, ensuring an accessible approach to successful load testing.
Target Audience
This course is designed for a wide range of individuals, including quality assurance engineers seeking to expand their expertise, regardless of prior experience with Gatling. It is also ideal for programmers interested in exploring load testing but who may not be familiar with Gatling. Furthermore, if you are currently using other load-testing tools like JMeter, LoadRunner, or NeoLoad and wish to transition to a new tool, this course will provide you with the knowledge and skills to become proficient in Gatling.
Learning Objectives
- Install and configure Gatling for both standalone use and within an Integrated Development Environment (IDE).
- Set up your development environment to efficiently write Gatling load-testing scripts.
- Master the process of refactoring Gatling code to ensure reusability across different testing scenarios.
- Execute tests from the command line using build tools such as Maven and Gradle.
- Monitor the execution of tests directly from the command line within Gatling.
- Integrate Gatling tests into a Continuous Integration (CI) pipeline using Jenkins and Travis CI for seamless automation.
