Can not use shinytest for larger application

[alik33]

Hello, I need to test my shiny application so I have downloaded shinytest and followed this tutorial - https://www.rstudio.com/resources/webinars/testing-shiny-applications-with-shinytest/ .

When I run recordTest() on a small application, it works fine. But I have a big application that I need to create tests for and I can not run recordTest() above this application. It outputs the following lines:

Error in sd_startShiny(self, private, path, seed) : 
  Cannot find shiny port number. Error:
Running application in test mode.

My application needs to be tested is quite big. It connects to database, retrieves data from database, sources many files. In lines printed above you can clearly see from the last line that it probably timeouts. gdata: Unab - probably it was meant Unable ....

I saw people dealing with this here - https://github.com/rstudio/shinytest/issues/111 - but there is no clear answer how to fix that.

Thank you for any help.

What happens when you suppress the package load messages (suggested in the issue you linked to)?

@EconomiCurtis I have already fixed it. Check the last comments here https://github.com/rstudio/shinytest/issues/111 and you will see how. Thanks anyway!

If your question's been answered, would you mind choosing a solution (even if it's just your post with the reference to the issue)? (see FAQ below for how) It makes it a bit easier to visually navigate the site and see which questions still need help.

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

Sure. I was looking for a button but could not find. Now I see it ;). Thanks

Yeah— it's kinda hidden, that's why I made that little pictorial!
