  taskcluster/docs/attributes.rst
  taskcluster/taskgraph/create.py
  taskcluster/taskgraph/target_tasks.py 

which should match

  taskgraph-tests:
    task: tasks/tests/taskgraph-tests.yml
    root: true
    when:
      file_patterns:
        - 'taskcluster/**.py'
        - 'config/mozunit.py'
        - 'python/mach/**.py'

Attachment: Bug 1293397: run taskgraph-tests when things change;
