[PATCH 24/24] t5601: basic bundle URI tests

From: Derrick Stolee via GitGitGadget <gitgitgadget@gmail.com>
Date: May 20, 2022, 18:40 UTC
Message-ID: <de1a0ce0919d3a25c95db2fce060ded36982da4d.1653072042.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.1234.git.1653072042.gitgitgadget@gmail.com>

From: Derrick Stolee <derrickstolee@github.com>

This test demonstrates an end-to-end form of the bundle URI feature given by an HTTP server advertising the 'features' capability with a bundle URI that is a bundle file on that same HTTP server. We verify that we unbundled a bundle, which could only have happened if we successfully downloaded that file.

RFC-TODO: Create similar tests throughout the series that perform
similar tests, including examples with table of contents and partial
clones.

 # DO NOT add non-httpd-specific tests here, because the last part of this
