nf-test with the google-batch executor

[chuck-fsdx]

I'm using nf-test 0.9.2, and I'm trying to execute a pipeline test with Google Batch as the executor.

My nf-test.config contains the following directive:

config {
    workDir "gs://workdirbucket/{my-project-name}"
    configFile "configs/nf-test-gcloud.conf"

and the referenced config file specifies the 'google-batch' executor:

process {
    executor = 'google-batch'
    machineType = "n2-*"
    errorStrategy = 'retry'
}

When I attempt to run my test, nf-test doesn't use the google bucket as a work directory. Instead, it creates a local directory called "gs:", and then throws the following error after trying to run:

Executor `google-batch` requires a Google Storage bucket to be specified as a working directory -- 
Add the option `-w gs://<your-bucket/path>` to your run command line or specify a workDir in your config file 
-- Check script '/{my_project_name}/./modules/main-module/main.nf' at line: 41 or see
 '/{my_project_name}/gs:/workdirbucket/{my_project_name}/tests/aab93aca2daa2f460a73162f2a47aefc/meta/nextflow.log' file for more details

Is this a use case that is known to work, and I'm just messing up the settings somehow? Or has no one else attempted to run nf-test with a google-batch executor yet?

Thank you for reporting this. Cloud executors are not yet supported at the moment, but we are working to implement them in the next release.

Thanks for the reply! Looking forward to that setup being supported.
