An HTTP Archive (HAR) file is a JSON-formatted archive file format for logging an application’s (either browser or a native/hybrid app) interaction with HTTP servers. The HAR file format is an evolving standard and the information contained within it is both flexible and extensible. You can expect a HAR file to include a breakdown of timings including:
- How long it takes to fetch DNS information.
- How long each object takes to be requested.
- How long it takes to connect to the server.
- How long it takes to transfer assets from the server to the browser of each object.
In addition to the timing information, the HAR file may include details regarding any HTTP events generated during the script execution.
Perfecto provides support for generating a HAR file from an automation script run by activating the Network Virtualization functionality of the Perfecto Lab. The HAR file will be included in the Reporting artifacts for the automation report.
