+    test ! -f $FILE_THAT_SHOULD_NOT_EXIST
+or:
+    ! $COMMAND_THAT_SHOULD_FAIL
+
+as appropriate.

+Subject: [PATCH] Fix test-lz4-basic
+
+When no output filename is specified and stdout is not a terminal,
+lz4 doesn't attempt to guess an output filename and uses stdout for
+output.
+
+This change fixes test-lz4-basic when run without a terminal
+by specifying output filenames.
