load_timeout not working

Dear all,

I suppose I am the cause of the issue or I did not understand how to make it work but I have a shiny app that makes use of a lot of libraries taking a lot of time to be loaded and the default chromote timeout of 10 seconds in not enough. I always get the following issue.

ℹ AppDriver logs:
{shinytest2} R info   14:25:15.33 Start AppDriver initialization
{shinytest2} R info   14:25:15.33 Starting Shiny app
{shinytest2} R info   14:25:15.98 Creating new ChromoteSession
{shinytest2} R info   14:25:16.06 Setting window size: 899x1619
{shinytest2} R info   14:25:16.06 Setting window size to `1619`x`899`
{shinytest2} R info   14:25:16.07 Navigating to Shiny app
{shinytest2} R info   14:25:26.07 Error while initializing AppDriver:
                                  Chromote: timed out waiting for response to command Page.navigate

It seems that after 10 seconds, the app is interrupted and I cannot test it.

I tried using a lot of ways (environment variables, parameters in new()) but whathever I try, it does not seem to change anything. Am I the only one experiencing this issue. Do I do something wrong when updating the values of load_timeout and timeout in when initialzing the AppDriver?

Here is how I start the AppDriver. From my understanding, to timeout shoud now be 13, but the options does not change anything.

  app <- AppDriver$new(
    name = "myapp",
    height = 899, width = 1619,
    view = F,
    expect_values_screenshot_args = FALSE,
    load_timeout = 13000,
    timeout = 13000
  )

Many thanks for your insights

Start by reproducing the failure with the shown AppDriver$new call, using load_timeout and timeout set to 13000, and inspect the AppDriver initialization log around Chromote's Page.navigate command. Compare the configured values with the observed 10-second timeout; done means the app can load beyond the default timeout or the configuration failure is clearly reported.
