First, we need to actually disable a subbank before we check that a subbank is disabled (invoke the tool with -d). Second, the original pipe to wc -l was to check that the tool prints only one line, not that it prints "at least" a line. Modify the last check to verify that an "is disabled" text is _not_ printed. v2: Add a TODO comment Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101650 Signed-off-by: Petri Latvala Reviewed-by: Abdiel Janulgue --- tests/tools_test.c | 87 +++++++++++++++++++++++++++++++----------------------- 1 file changed, 50 insertions(+), 37 deletions(-) diff --git a/tests/tools_test.c b/tests/tools_test.c index 132bb88b..6aea7a8a 100644 --- a/tests/tools_test.c +++ b/tests/tools_test.c @@ -28,26 +28,31 @@ #include struct line_check { - bool found; + int found; const char *substr; }; /** * Our igt_log_buffer_inspect handler.
