Error: unable to start device PNG only when recording a test

alessap commented 4 years ago

Dear All,

I have created a very simple dashboard following golem framework and when run the app looks like this:

However, when I record a test, the histogram is not rendered correctly and it looks like this;

From the R session (3.6.0):

> capabilities()
       jpeg         png        tiff       tcltk         X11        aqua    http/ftp     sockets      libxml 
       TRUE        TRUE        TRUE        TRUE       FALSE       FALSE        TRUE        TRUE        TRUE 
       fifo      cledit       iconv         NLS     profmem       cairo         ICU long.double     libcurl 
       TRUE        TRUE        TRUE        TRUE        TRUE        TRUE        TRUE        TRUE        TRUE 

> options("bitmapType")
$bitmapType
[1] "cairo"

I have installed phantomjs and all its dependencies on the server where I am running my development environment.

Does anybody have any idea what is wrong with this?

Best regards, Alessandro

Adding options(bitmapType='cairo') to my .Rprofile file in the project folder solved the issue.

rstudio / shinytest
