Subject: [PATCH ima-evm-utils 5/8] Introduce TST_LIST variable to select a test to execute
Date: Mon,  9 Jan 2023 17:55:49 +0100	[thread overview]
Message-ID: <20230109165552.3409716-6-roberto.sassu@huaweicloud.com> (raw)
In-Reply-To: <20230109165552.3409716-1-roberto.sassu@huaweicloud.com>

From: Roberto Sassu <roberto.sassu@huawei.com>

It might be desirable, due to restrictions in the testing environment, to
execute tests individually. Introduce the TST_LIST variable, which can be
set with the name of the test to execute. If the variable is set,
expect_pass and expect_fail automatically skip the tests when the first
argument of those functions does not match the value of TST_LIST.

TST_LIST can be also used in conjunction with the UML kernel. It is
sufficient to add it to the kernel command line.
