Question 1

How do I convert a HAR file to a k6 script using the CLI?

Accepted Answer

After installation, run 'har-to-k6 archive.har -o output.js' locally, or use Docker with 'docker run grafana/har-to-k6:latest archive.har > output.js'. The README provides detailed CLI examples for different setups.

Question 2

What's the difference between HAR and LI-HAR in har-to-k6?

Accepted Answer

HAR is a standard HTTP archive format, while LI-HAR is Load Impact's extended version with k6-specific configurations. har-to-k6 supports both, but LI-HAR may include additional metadata for better k6 script accuracy.

Question 3

How can I integrate har-to-k6 into a CI/CD pipeline?

Accepted Answer

Use the Docker image or Node.js API in pipeline scripts; for instance, call the programmatic liHARToK6Script function in a Node.js step. This ensures consistent, automated conversions without manual intervention.

Question 4

har-to-k6 vs other HAR conversion tools: which should I use?

Accepted Answer

har-to-k6 is best for k6 users due to official Grafana support and optimized output. For other frameworks like Apache Bench or Gatling, consider tools like 'har2jmeter' or 'har-recorder', as har-to-k6 only targets k6.

Question 5

How to handle authentication in converted k6 scripts?

Accepted Answer

The conversion captures HTTP requests from HAR files, but you may need to manually adjust sessions or tokens in the generated script, as HAR might not include all dynamic authentication flows.

Question 6

Can I validate a HAR file without converting it?

Accepted Answer

Yes, use the validate() function from the programmatic API to check archive integrity before full conversion, helping catch format errors early without generating scripts.
