+### Summary
+
+This is a baseline (bl) test case for issue #156. It verifies that the `clusterinfo` fixture
+will use the value specified by the `--kube-config` command line arg when specified. See
+[regression/156](../156) for more details.
+
+#### Expectations
+
+When run with a command-line defined kubeconfig, a test using the `clusterinfo` fixture should
+resolve the cluster info using the kubeconfig specified by the command line flag.

+### Summary
+
+When the kubeconfig is provided by a pytest fixture and not via the `--kube-config` command line
+flag, the `clusterinfo` fixture will fail, since it uses the kubeconfig value specified by the
+command line flag and does not account for custom fixture.
