+# Ansible role for selecting tests to be run
+
+Put this role in your test_local.yml playbook.
+
+You'll need to have the following input variables defined:
+
+* tests_docker: A list of tests to run only in a docker container (optional)
+* tests_not_docker: A list of tests to run only when NOT in a docker container (optional)
+* tests_all: A list of tests to always run (optional)
+
+When the role is completed, the following variable will be set:
+
+* selected_tests: The list of selected tests
+
+Run another role in your playbook after this role to run the list of selected tests. For example, standard-test-rhts.
+
+```yaml
+---
+# This first play always runs on the local staging system
+- hosts: localhost
+
+  roles:
+  - role: standard-test-selector
+    tests_docker:
+    - dockertest1
+    - dockertest2
+    tests_not_docker:
+    - nondockertest1
+    - nondockertest2
+    tests_all:
+    - alltest1
+    - alltest2
+
+  - role: standard-test-rhts
+    tests: "{{ selected_tests }}"
+    required_packages:
+    - package1          # alltest1 needs foo command
+```
