Sometimes you want to check SLA of your API automatically. There are many tools for profiling or stressing your software, but all of them have the enormous complexity or analyze results by third party tools. This project helps you do it easy and in a straightforward way. One configuration file with a simple structure is needed. In configuration file you need to declare the target, attack time, request frequency and (this is the most important part) SLA for target service (99th latency percentile and percentage of successful requests). And if any test is failed, the program will print report and exit with error code. It gives simple integration with different continuous delivery tools.
