Run all cram tests from the specified paths on the specified
clients. Each client runs tests in parallel.
Limitations:
Tests must have a .t suffix. Tests with duplicate names will
overwrite each other, so only the last one will run.
For example::
tasks:
- ceph:
- cram:
clients:
client.0:
- qa/test.t
- qa/test2.t]
client.1: [qa/test.t]
branch: foo
You can also run a list of cram tests on all clients::
tasks:
- ceph:
- cram:
clients:
all: [qa/test.t]
