Hi
I'm trying to run a test with shinytest for a shiny app that lives inside an R package (from Bioconductor).
I can record the test but I can't run it.

This is my code from a clean session:


library(shinytest)
recordTest("~/curro/gsva-devel/GSVA/inst/shinyApp", loadTimeout = 1e+05)

This is the result in console:

Saved test code to /home/bort/curro/gsva-devel/GSVA/inst/shinyApp/tests/shinytest/mytest.R
Running mytest.R Query failed (500)----------------------

This is the file created at "~/curro/gsva-devel/GSVA/inst/shinyApp/tests/shinytest/mytest.R"
(I load the shiny app, click on a couple of inputs and save the snapshot, I don't plot anything)

app <- ShinyDriver$new("../../", loadTimeout = 1e+05)
app$snapshotInit("mytest")

app$setInputs(`matrix1-matrixSourceType` = "varMatrix")
app$setInputs(`genes1-genesetSourceType` = "varGeneset")
app$setInputs(arg = "yes")
app$setInputs(`argumentsInput-kcdf` = "Poisson")
app$snapshot()

Hi, I got the same error in one of my tests. In my case it was due to having validate() returning a 'shiny.silent.error' within plotly::renderPlotly(). I replaced the plotly plot with ggplot2 and used shiny::renderPlot() and it passed the test.

So maybe it's worth checking if there's anywhere in your app that returns a silent error it's not working well with some third party functions?

I'm having the same issue...
Thank you for the insight, @MohoWu .
However, I really need plotly, I cannot replace it with ggplot2, I wonder if there is a workaround for that.

I am having the same issue as pablo, just the error which pops up is:
Running mytest.R Error in httr_get(url): Shiny app is no longer running.
Anyone knows the solution to it?

Hi all -- now that we have shinytest2, my first suggestion would be to see if you can migrate to the newer framework. There are a lot of reasons to do so that are outlined on the shinytest2 site.

That said, I'd be happy to look into this issue, but it would be difficult to do so without a reproducible example.

Hi gadenbuie, thanks for your response. For now i can only use shinytest package and can not migrate to the newer shinytest2 framework. But the correction of the source code (namely correction of function httr_get - function) as in issue 387 - #387 was helpful with regard to my issues.
