Subject: test: Add some setexpr regex tests
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e713124e352efe3141af6a4ffc83f6dba449a177;p=u-boot.git

test: Add some setexpr regex tests

Add tests for the setexpr regex commands.

Note that these tests currently crash on sandbox due to an existing bug in
the setexpr implementation, so two of the tests are commented out.
