Subject: [PATCH 1/5] t6036, t6042: use test_create_repo to keep tests independent
Date: Thu, 24 May 2018 00:04:35 -0700	[thread overview]
Message-ID: <20180524070439.6367-2-newren@gmail.com> (raw)
In-Reply-To: <20180524070439.6367-1-newren@gmail.com>

These tests used pretty strong measures to get a clean slate:
        git rm -rf . &&
        git clean -fdqx &&
        rm -rf .git &&
        git init &&
It's easier, safer (what if a previous test has a bug and accidentally
changes into a directory outside the test path?), and allows re-inspecting
test setup later if we instead just use test_create_repo to put different
tests into separate sub-repositories.
