+    Scenario: Writing an entry at the prompt with custom date
+        Given we use the config "little_endian_dates.yaml"
+        When we run "jrnl" and enter "2013-05-10: I saw Elvis. He's alive."
+        Then we should get no error

+    Scenario: Viewing today's entries does not print the entire journal
+        # see: https://github.com/jrnl-org/jrnl/issues/741
+        Given we use the config "simple.yaml"

+        Given we use the config "simple.yaml"
+        When we run "jrnl <command>"
