URL: https://github.com/apache/arrow/pull/13542#issuecomment-1180801174

   Tests seem to be failing right now because of a difference in how GCS and S3 handle paths:
   
   ``` r
   library(arrow)
   #> 
   #> Attaching package: 'arrow'
   #> The following object is masked from 'package:utils':
   #> 
   #>     timestamp
   
   example_data <- arrow_table(x = Array$create(c(1, 2, 3)))
   
   testbench_port <- Sys.getenv("TESTBENCH_PORT", "9001")
   fs <- GcsFileSystem$create(
     endpoint_override = sprintf("localhost:%s", testbench_port),
     retry_limit_seconds = 1,
     scheme = "http",
     anonymous = TRUE # Will fail to resolve host name if anonymous isn't TRUE
   )
   fs$CreateDir("test")
   write_parquet(example_data, fs$path("test/test.parquet"))
   write_parquet(example_data, fs$path("test/test.parquet/"))
   # GCS seems to handle them as separate paths
   fs$ls("test")
   #> [1] "test/test.parquet" "test/test.parquet"
   
   
   minio_key <- Sys.getenv("MINIO_ACCESS_KEY", "minioadmin")
   minio_secret <- Sys.getenv("MINIO_SECRET_KEY", "minioadmin")
   minio_port <- Sys.getenv("MINIO_PORT", "9000")
   fs <- S3FileSystem$create(
     access_key = minio_key,
     secret_key = minio_secret,
     scheme = "http",
     endpoint_override = paste0("localhost:", minio_port),
     allow_bucket_creation = TRUE,
     allow_bucket_deletion = TRUE
   )
   fs$CreateDir("test")
   write_parquet(example_data, fs$path("test/test.parquet"))
   write_parquet(example_data, fs$path("test/test.parquet/"))
   # S3 implementation seems to remove the last slash
   fs$ls("test")
   #> [1] "test/test.parquet"
   ```
