Testing K6 Dynamic Analysis Tool

[a1inachen]

What?

• Installed and tested the Grafana K6 dynamic analysis (peformance testing) tool on our team repository.
• A k6 test script k6-test.js stress tests the traffic to our team's deployed website. The number of virtual users starts at 10 and doubles every 30 seconds until reaching a max of 160 users. We verify that the average failure rate of HTTP requests should be at most 20% and the 95th percentile of HTTP request duration is at most 3 seconds as part of the thresholds check. A run of this test was done locally and is done in the Github deployment workflow actions check.
• Additionally in the k6-test.js script, we functionaly test the Solved/Unsolved button on our app from User Story 2, verifying that as an instructor (admin), the button toggles between the two states appropriately.

Why?

• Testing and research of K6 tool. Will evaulate its usefulness in terms of catching our code mistakes for our app, especially in terms of scalability, performance, and functionality.
