Testing details

1. Manual -

• Manually ran on GCP VM using the following commands:

GODEBUG=asyncpreemptoff=1 go test ./tools/integration_tests/local_file/...  -p 1 --integrationTest -v --testbucket=$TEST_BUCKET_NAME

GODEBUG=asyncpreemptoff=1 go test ./tools/integration_tests/local_file/...  -p 1 --integrationTest -v --testbucket=$TEST_BUCKET_NAME --testInstalledPackage

• Ran the following commands for mounted directory tests

# package local_file
# Run test with static mounting. (flags: --implicit-dirs=true)
gcsfuse --implicit-dirs=true --rename-dir-limit=3 $TEST_BUCKET_NAME $MOUNT_DIR
GODEBUG=asyncpreemptoff=1 go test ./tools/integration_tests/local_file/... -p 1 --integrationTest -v --mountedDirectory=$MOUNT_DIR --testbucket=$TEST_BUCKET_NAME
sudo umount $MOUNT_DIR

# Run test with static mounting. (flags: --implicit-dirs=false)
gcsfuse --implicit-dirs=false --rename-dir-limit=3 $TEST_BUCKET_NAME $MOUNT_DIR
GODEBUG=asyncpreemptoff=1 go test ./tools/integration_tests/local_file/... -p 1 --integrationTest -v --mountedDirectory=$MOUNT_DIR --testbucket=$TEST_BUCKET_NAME
sudo umount $MOUNT_DIR
