retry function

Documetation of retry argument

The ability to retry function code is enabled by default. retry can be a logical value. if it is TRUE then noTry = getOption("seleniumPipes_no_try") and delay = getOption("seleniumPipes_no_try_delay"). If it is FALSE the facility to have multiple trys of the function call is removed. retry can also be a list with the following named arguments that will override the values in options

• "noTry": Integer indicating how many times to try the function call
• "delay": Integer indicating delay between trys of the function call

Examples

## Not run:

remDr <- remoteDr()
webElem <- remDr %>% go("http://www.google.com/ncr") %>%
  findElement("name", "q")
# change the name of q with an 8 second delay
myscript <- "var myElem = arguments[0];
window.setTimeout(function(){
 myElem.setAttribute('name','funkyname');
}, 8000);"
remDr %>% executeScript(myscript, args = list(webElem))

newWebElem <- remDr %>% findElement("name", "funkyname")

# > newWebElem <- remDr %>% findElement("name", "funkyname")
#
# Calling  findElement  - Try no:  1  of  3
#
# Calling  findElement  - Try no:  2  of  3

newWebElem %>% getElementAttribute("name")

# compare with a function that will fail (no element present)
remDr %>% findElement("id", "i am not here", retry = list(noTry = 5, delay = 10))
remDr %>% findElement("id", "i am not here", retry = FALSE)
## End(Not run)
