+Doctor now supports different test cases and for that you might want to
+export TEST_CASE with different values:
+
+.. code-block:: bash
+
+ #Fault management (default)
+ export TEST_CASE='fault_management'
+ #Maintenance (requires 3 compute nodes)
+ export TEST_CASE='maintenance'
+ #Run both tests cases
+ export TEST_CASE='all'
+
