Add --console hidden option for debug test cases. This option allows to put "sh" or something else when the test case hits a bug. For example, if you find a testcase which doesn't pass, you can insert sh for interactive debug as below ----- #!/bin/sh # description: sample test case good-command suspicious-wrong-command sh # <- add this for interactive debug ----- Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> --- Changes in v3 - Add an example of this feature in the description --- tools/testing/selftests/ftrace/ftracetest | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-)
