How to test git hooks
提问by Errol
Since "testing" is a common use for a Git hook, my question is hard to search for.
由于“测试”是 Git 钩子的常见用途，因此很难搜索我的问题。
I'm writing a fairly involved git post-receive hook and want to know what the best way to test it is. Currently my process is:
我正在编写一个相当复杂的 git post-receive hook，想知道测试它的最佳方法是什么。目前我的流程是：
- make changes to post-receive in a dummy "remote" repo
- make a change to a dummy local repo
- commit change in dummy local repo
- push change to dummy remote repo
- 在虚拟的“远程”存储库中对 post-receive 进行更改
- 对虚拟本地仓库进行更改
- 在虚拟本地仓库中提交更改
- 将更改推送到虚拟远程仓库
Is there any easier way to test this? Ideally it would look like:
有没有更简单的方法来测试这个？理想情况下，它看起来像：
- make change(s) to post-receive in a dummy repo
- issue "magic" command to test post-receive
- 在虚拟仓库中对接收后进行更改
- 发出“magic”命令来测试接收后
Perhaps I can "reissue" a previous push or have the remote repo act as though it just received a push with a specific hash?
也许我可以“重新发布”以前的推送，或者让远程仓库表现得好像它刚刚收到了具有特定哈希值的推送？

Write a hook that just records its arguments/environment and dumps that to a file. Then you can just re-invoke the real hook at your leisure with the same environment/arguments and it will act as though you just re-issued the exact same push.
编写一个仅记录其参数/环境并将其转储到文件的钩子。然后，您可以在闲暇时使用相同的环境/参数重新调用真正的钩子，它的行为就像您刚刚重新发出完全相同的推送一样。

If you'd like to test hook in local environment, I give the detail commands for following up, use post-receiveas sample:
如果你想在本地环境中测试钩子，我给出了后续的详细命令，post-receive用作示例：
$ mkdir /tmp/hook_test
$ cd /tmp/hook_test
# set local git repo, where you put hooks in it.
$ git clone --bare https://github.com/git/git.git
# set develop environment which is cloned from the new created repo.
$ git clone git.git repo
# copy and rename the hook you need test to "post-receive"
$ cd git.git/hooks
$ cp ~/post-receive-test post-receive
# suppose the hook script is bash script.
# edit "post-receive" and add "set -x" to second line in it to active debug
$ cd /tmp/hook_test/repo
# emulate a hook trigger, do some changes, "git add" and "git commit" it
$ git push
# Now you should see the script "post-receive" runs automatically with debug details.
You should be free to run git push, that the updates are only pushed to local repo /tmp/hook_test/git.git
您应该可以自由运行git push，更新仅推送到本地存储库/tmp/hook_test/git.git

My approach is to dial the HEAD at the remote repo back one commit, and then push again:
我的方法是将远程仓库中的 HEAD 拨回一次提交，然后再次推送：
ssh <repo> 'cd /<repo_path>; git update-ref refs/heads/master HEAD^' && git push origin master

For debugging you could also end your hook in something like this:
对于调试，您还可以以如下方式结束钩子：
echo "No errors found."
exit 1
If you are happy with you hook you of course take out the last line again.
如果您对钩子感到满意，当然可以再次取出最后一行。
