Re: [Libguestfs] [PATCH nbdkit] s3: Only run the tests if boto3 is installed

OK I see what's going on. test-S3.sh uses the mocked boto3 in tests/test-S3/ to do an end-to-end test (nbdcopy). test-S3-unit.sh runs the unit tests within the plugin. It's basically testing the plugin as if it was a standalone Python script (without nbdkit being involved). This uses an internal MockS3Client class also inside the plugin. The second one does actually need real boto3, just because there's an "import boto3" at the top and we don't set up PYTHONPATH to pick up the tests/test-S3/ subdirectory. We could either fix the second one by skipping it if (real) boto3 isn't installed, or by making it use the mocked boto3 from tests/test-S3/ Either approach would work, but the second one (below) seems maybe better because we'd get more test coverage this way?
