描述
Description
Karate HTML reports work well for the summary page and for feature reports with a small number of scenarios. However, opening the HTML report for a feature with many scenarios is extremely slow and consumes a large amount of browser memory.
Environment
| Item | Value |
|---|---|
| Karate version | 2.0.10 |
| Java version | 21 |
| OS | Ubuntu 24.04.4 LTS |
| Browser | Chrome Version 149.0.7827.155 (Official Build) (64-bit) |
| Report type | HTML (default) |
Affected feature
- Number of scenarios: 177
- Generated HTML report file size of the specific feature: ~42 MB
- Time to open/render in browser: ~1 min 40 sec
- Browser memory usage while loading: ~6 GB
- The report is served over HTTP
Expected behavior
The feature HTML report should load in a reasonable time without consuming several GB of RAM.
Actual behavior
- The feature report page takes ~100 seconds to become usable.
- Chrome uses ~6 GB of memory during/after loading.
- Smaller feature reports and the summary page work fine.
Additional context
- Tried to open it locally via
file://, similar behavior - Tested in Edge, same behavior
