Pumba vs Kahlan: What are the differences?
What is Pumba? Chaos Testing Tool for Docker Containers. It is a chaos testing tool for Docker containers, inspired by Netflix Chaos Monkey. The main benefit is that it works with containers instead of VMs. It can kill, stop, restart running Docker containers or pause processes within specified containers. We use it for resilience testing of our distributed applications.
What is Kahlan? A full-featured Unit & BDD test framework. It is a full-featured Unit & BDD test framework a la RSpec/JSpec which uses a describe-it syntax and moves testing in PHP one step forward.
Pumba and Kahlan can be categorized as "Testing Frameworks" tools.
Some of the features offered by Pumba are:
- Chaos injection with network emulation
- simulate network delay and packet loss
- delay of all outgoing packets
On the other hand, Kahlan provides the following key features:
- RSpec/JSpec syntax
- Code Coverage metrics (xdebug or phpdbg required)
- Handy stubbing system (mockery or prophecy are no longer needed)
Pumba and Kahlan are both open source tools. It seems that Pumba with 1.42K GitHub stars and 115 forks on GitHub has more adoption than Kahlan with 1K GitHub stars and 54 GitHub forks.
