Thanks for the hint, Hendrik!
However, this change did not make a difference :/

I tried to use all cluster closing functions I came across but tests are
still running infinite..

cl <- makeCluster(par.args$par.units, outfile = out.progress)
registerDoParallel(cl)

foreach()

parallel::stopCluster(cl)
doParallel::registerDoSEQ()
doParallel::stopImplicitCluster()

Use

  registerDoParallel(cl)

The number of parallel workers is already contained in the 'cl' object,
so don't specify 'cores'!  (If you do that, I suspect you create yet another
cluster (a multicore one) which is used but never closed)

registerDoParallel() should ideally give an error in your case. Author

Dear Uwe,

thanks for the hint. My cluster is closed after the `foreach`call using
`stopCluster()`.

Before, I?ll do the following to init the cluster:

*cl <- makeCluster(par.args$par.units, outfile = out.progress)*
*registerDoParallel(cl, cores = par.args$par.units)*

*foreach()*

*stopCluster(cl)*


Do you know of any other package which is using foreach in combination
with
tests and is hosted on Github? So I could compare settings.

Best, Patrick

Check whether the parallel cluster is closed. Can it be that the
cluster
is still open and the check process waits for them to complete?

Best,
Uwe Ligges

Hello,

when running R CMD check / devtools::check, section "running
tests..." is
not finishing (40 min+).

*Checking tests only works:*

*==> Sourcing R files in 'tests' directory*

*testthat results
================================================================*
*OK: 7 SKIPPED: 0 FAILED: 0*

*Tests complete*


As well as running tests line-by-line.

How can I debug my tests to discover the problem during R CMD check?

*Tests are using parallelization (foreach + doParallel)*

Best, Patrick
