我们正在尝试将我们的 CI 从 Travis 移植到 Heroku。测试在本地和 Travis 上都通过了,但是在 Heroku 上,我们遇到了一些难以调试的 erlang 错误。
所有错误似乎都来自于在模拟AWS S3 请求时使用 Elixir Mock模块的测试。
这是一个示例测试:
test "put_object failure function" do
with_mock ExAws, [request!: fn(_) -> %{status_code: 500} end] do
res = S3.put_object("unique.png", "binary")
assert res == {:error, "error uploading to S3"}
end
end
而 put 对象很简单:
def put_object(unique, image_binary) do
bucket = System.get_env("BUCKET_NAME")
res = ExAws.S3.put_object(bucket, unique, image_binary)
|> ExAws.request!
case res do
%{status_code: 200} ->
{:ok, image_url(unique, bucket)}
_ ->
{:error, "error uploading to S3"}
end
end
所以我不太确定出了什么问题。
Heroku CI 的错误在这里:
