appDriver ignores enableBookmarking argument

[gogonzo]

I'm trying to test an app which displays button conditionally depending whether bookmarkStore option is set or not.

library(shiny)

# bookmarkable shiny app
ui <- fluidPage(
  textInput("text", "Text", ""),
  uiOutput("bookmark_button")
)

server <- function(input, output, session) {
  shiny_option <- getShinyOption("bookmarkStore", "disabled")
  print(shiny_option)
  output$bookmark_button <- renderUI({
    if (shiny_option != "disabled") {
      bookmarkButton("Bookmark")
    } else {
      NULL
    }
  })
}

app <- shinyApp(ui, server, enableBookmarking = "url")

1. The app run normally displays bookmarkButton

app

2. The app run through appDriver doesn't display a button

remdr <- shinytest2::AppDriver$new(app)
browseURL(remdr$get_url())

---

Question:

• how to force appDriver to use enableBookmarking?

I have found out that it also ignores onStart argument.

library(shiny)

ui <- fluidPage(
  titlePanel("Simple Shiny App"),
  sidebarLayout(
    sidebarPanel(
      sliderInput("num_points", "Number of Points", min = 10, max = 100, value = 50)
    ),
    mainPanel(
      plotOutput("scatter_plot")
    )
  )
)

server <- function(input, output) {
  output$scatter_plot <- renderPlot({
    x <- rnorm(input$num_points)
    y <- rnorm(input$num_points)
    plot(x, y, main = "Scatter Plot", xlab = "X", ylab = "Y")
  })
}

app <- shinyApp(ui, server, onStart = function() print("hello!"))

app_driver <- shinytest2::AppDriver$new(app)
on.exit(app_driver$stop(), add = TRUE)

app_driver$get_logs()

There should be my hello print somewhere.

I have also found that onStart is ignored.

This is unfortunate because I'd like to pkgload::load_all in the child process so it has access to the shiny app package I am testing.
