HAR to K6 Script Conversion: Bridging HTTP Archive Files with Performance Testing Frameworks

Abstract

Performance testing plays a crucial role in ensuring the reliability and responsiveness of web applications. HTTP Archive (HAR) files, widely used for capturing browser network activity, contain valuable insights into application performance. However, translating these insights into actionable load tests often requires manual effort, especially when creating scripts for K6, a powerful performance testing framework. This paper presents an automated solution for converting HAR files into K6 scripts, enabling testers to streamline the script generation process. By reducing manual effort, enhancing script accuracy, and integrating seamlessly into existing workflows, this utility addresses key challenges faced by development and quality assurance teams. The paper discusses the technical approach, implementation details, and benefits of the tool, along with real-world use cases demonstrating its impact on performance testing efficiency.
