how to inject fault incrementally and explore all code flow area using hadoop fault injection framework

hadoop fault injection framework - how to inject fault incrementally and explore all code flow area in a deterministic way (not hitting the same call flow/exception again)

I gone throw the below topic, it is based on probability model and it requires lot of iterations (due to probability it hits the same call flow/exception again) to cover the complete code flow.

https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-hdfs/FaultInjectFramework.html

is there any other framework or technique using that we can inject fault incrementally and explore all code flow area in a deterministic way
