[Bioc-devel] BrowserViz build test times out, checks for web browser availability, apparently needs update

The BrowserViz package - currently timing out on malbec1 and nebbiolo1, supports json messaging over websockets between R and most web browsers.  

The unit tests for BrowserViz only run if a web browser is available.   In recent years, a (presumably headless) web browser was offered on the Linux build machines. Depending on that, and for a few years, the following conditional execution has worked.  But maybe no longer?

webBrowserAvailableForTesting <- function() {
  authorsDevelopmentMachine <- grepl("hagfish", Sys.info()["nodename"])
  bioconductorBuildSystem.linux <- with(as.list(Sys.info()), sysname == "Linux")
  interactiveUse <- interactive()
  return(authorsDevelopmentMachine || bioconductorBuildSystem.linux || interactiveUse)

Any suggestions?

Thank you,

 - Paul
