+# This test validates that a `src.ctf.lttng-live` component successfully does
+# various tasks that a `src.ctf.lttng-live` component is expected to do, like
+# listing tracing sessions and receiving live traces / producing the expected
+# messages out of it.
#
-# Such CTF traces to open either exist (in `tests/ctf-traces/`)
-# or are generated by this test using local trace generators.
+# A mock LTTng live server is used to feed data to the component.
