Subject: test: Record and silence console in tests
X-Git-Tag: v2016.01-rc2~195
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9ce8b40206f4f96de6164c2a0c0a725c9323c4b9;p=platform%2Fkernel%2Fu-boot.git

test: Record and silence console in tests

When running sandbox tests, silence the console to avoid unwanted output.
Also, record the console in case tests want to check it.

The -v option can be used to enable stdout during tests.
