Tulip

1. Documentation

Tulip is a Kotlin SDK to create load testing, stress testing, and performance regression testing benchmarks for software systems. Tulip is a robust solution for evaluating the performance and stability of web applications under varying conditions, ensuring they can handle high traffic and stress levels efficiently. Similar to well-known tools like JMeter, Gatling, and Locust, Tulip provides powerful capabilities to simulate real-world scenarios and generate comprehensive reports, helping developers identify and resolve potential bottlenecks.

See https://wfouche.github.io/Tulip-docs for more information.

2. Kwrk

kwrk is a HTTP benchmark utility implemented using the Tulip runtime. kwrk is similar in functionality to wrk and wrk2.

Show the options supported by kwrk:

$ jbang run kwrk@wfouche --help

Usage: kwrk [<options>]

Options:
  --debug=<text>
  --rate=<float>
  --qsize=<int>
  --threads=<int>
  --duration=<int>
  --iterations=<int>
  --header=<text>
  --url=<text>
  -h, --help          Show this message and exit

Run a low-volume, constant rate load test to test-api.k6.io

$ jbang run kwrk@wfouche \
    --rate=10.0 \
    --url=https://test-api.k6.io/public/crocodiles/1
....
....
Output filename = kwrk_output.json
Report filename = kwrk_report.html

The performance results are shown in kwrk_report.html. The results indicate that for this particular benchmark only 1 API call failed (#F is 1) and that the Aps (average number of actions per second) rate is 1.989 (~2.0). The number of failed operations are highlighted in $\textcolor{yellow}{yellow}$ (if it is greater than 0). The Aps rate does not meet the target of 10.0 that was set for the benchmark and is therefore highlighted in yellow.

Additional information about kwrk is provided in the Tulip documentation:
