Subject: tests/functional: add 'uncompress' to QemuBaseTest
X-Git-Tag: v10.0.0-rc0~114^2~13
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fd4abcb00839a310fc668d86177278e789f51688;p=thirdparty%2Fqemu.git

tests/functional: add 'uncompress' to QemuBaseTest

This helper wrappers utils.uncompress, forcing the use of the scratch
directory, to ensure any uncompressed files are cleaned at test
termination.
