+# Dockerpy regression test
+
+Python test suite to validate Podman endpoints using dockerpy library
+
+Running tests
+=============
+To run the tests locally in your sandbox:
+
+#### Make sure that the Podman system service is running to do so
+
+```
+sudo podman --log-level=debug system service -t0 unix:/run/podman/podman.sock
+```
+#### Run the entire test
+
+```
+sudo PYTHONPATH=/usr/bin/python python -m dockerpy.images
+```
+
+Passing the -v option to your test script will instruct unittest.main() to enable a higher level of verbosity, and produce detailed output:
+
+```
+sudo PYTHONPATH=/usr/bin/python python -m unittest -v dockerpy.images
+```
+#### Run a specific test class
+
+```
+sudo PYTHONPATH=/usr/bin/python python -m unittest -v dockerpy.images.TestImages
+```
+
+#### Run a specific test within the test class
+
+```
+sudo PYTHONPATH=/usr/bin/python python -m unittest -v dockerpy.images.TestImages.test_list_images
+```
