Course Description

Summary

This course provides you with the knowledge necessary to implement shift-left testing practices, including designing and executing load tests and analyzing results using OpenText™ Performance Engineering for Developers.

Overview

In this course, you will learn about the DevWeb script structure and create DevWeb scripts using various tools, such as OpenText™ Virtual User Generator (VuGen) and the DevWeb Proxy Recorder. DevWeb is included as a built-in protocol when you install OpenText™ Professional Performance Engineering, OpenText Virtual User Generator, or OpenText™ Enterprise Performance Engineering.

You will also learn how to use the DevWeb JavaScript SDK to enhance scripts by using functions, adding parameters, enabling correlation, and using filters to remove unwanted requests.

Additionally, you will learn how to run scripts directly from the Integrated Development Environment (IDE), use the ScalUP tool to run scripts on OpenText Enterprise Performance Engineering and OpenText™ Core Performance Engineering, integrate DevWeb tests into your pipelines using Jenkins, store test runs in InfluxDB, and configure the Grafana dashboard to view key metrics and analyze test results.

This course is ideal for developers and DevTesters who want to shift performance testing left in the development cycle to ensure application scalability and reliability.

By the end of this course, you will be able to design, create, run, integrate, and analyze DevWeb tests.

Highlights:

• Explain the main features and capabilities of OpenText Performance Engineering for Developers
• Design, create, enhance, and run DevWeb tests in various ways
• Integrate DevWeb tests into Jenkins pipelines
• Use third-party tools like InfluxDB and Grafana to monitor and analyze test results
