Delta-Testing, test only changed parts of the "infected" code-base

I'd like to speed up our integrationtest-suite. It is long running. Too long. As everyone knows not every change has an impact on everything. So why not just test components which are influenced by the change?

From infinitest I know, it is just ru开发者_StackOverflow中文版nning the related tests, so why not do the same on ... jenkins.

Is there any tool, what this is doing?

1000 Tests, 1 change, 10 related and only these 10 tests should run.

Related could be defined as related in code-coverage way.

I search for tools that are running tests in an analogous way to delta debugging.
