The tools you just mentioned are not quite the same as this one. Though they belong to this wide “testing” area. Also you of course can write tests on any programming language but you are going to do a lot of low level coding in this case.

DTAP is more for people like devops or operations not willing to do such a heavy lifting job. They just use existing check rules in plain Bash scenarios.

To create new checks knowledge of underlying Sparrow dsl - is required , however to use DTAP you don’t need such a knowledge. Sparrow dsl from other hand provides powerful and flexible mechanisms to deal with complexity of regexp and text patterns search, parsing and validation.

So long story short the tool is beneficial for test users and test ( check rules ) developers so they can leverage existing primitives whether these are check rules or Sparrow task check DSL
