英文:
AWS SAM - Copy files from local host while locally testing lambda
问题
需要从本地主机复制文件，同时使用AWS SAM测试Lambda函数。这将模拟在实际情况下从S3复制文件的情况。在本地测试期间，有没有办法从Lambda函数内部复制本地主机上的文件？
我尝试将本地目录挂载为Docker容器中的卷，以执行Lambda函数，但结果显示，在AWS SAM中将卷附加到Docker容器尚不受支持（这是GitHub请求 https://github.com/aws/aws-sam-cli/issues/2589，该请求仍然处于打开状态）。
英文:
I need to copy files from a local host while testing lambda using AWS SAM. This will simulate a case when in a real scenario files are copied from S3. Is there any way to copy files from a local host inside lambda while local testing?
I was trying to mount the local directory as a volume in a Docker container which executes lambda, but it turns out that attaching volumes to a Docker container in AWS SAM is not supported yet ( here is GitHub request https://github.com/aws/aws-sam-cli/issues/2589 which is still open )

你可以使用安装localstack 并将其用作测试中的虚假本地S3端点。如果从S3中提取数据对于你的Lambda函数至关重要，那么你的测试在全面性方面会有所改善。
英文:
You could use install localstack and use that in your tests as a fake, local s3 endpoint. If pulling data from s3 is crucial for your lambda then your tests would improve in their comprehensiveness.
