Load testing using LOCUST
Locust is an open source load testing tool. Load testing is a type of software testing that is conducted to check the tolerance/behavior of the system under a specific expected load. The target of locust is load-testing web sites and checking number of concurrent users a system can handle.
During a locust test, a swarm of locusts will attack the target i.e website. The behavior of each locust is configurable and the swarming process is monitored from a web UI in real-time.
Speciality of locust:
- Test scenarios can be written in Python
- Distributed and scalable
- Web-based UI
- Any system can be tested using this tool
Locust can be installed with pip.
