JavaScript
Important when identification requires logic (e.g.
parameterize)
Initial value provided based on evalXPath of first Xpath
suggested
The last statement is what’s returned and used by the step
JS function has a separate variable context from the script
itself
Access variable in script using ArgsContext.a for variable a
and ArgsContext.LR.getParam(“a”) for parameter a.

JavaScript
Record interaction with several options (e.g. radio buttons, table
cells)
Compare the Xpath values of the different objects and find the
common XPath
Change ID Method to Javascript and use evalXPath to get an array
of objects:
options=evalXPath("//div[@id=\"module-options-div\"]/div/div[2]/input");
Referance the array of objects to parameterize the object:
random(options) – select a random item
random(ArgsContext.item) – select an item based on the variable item
random(ArgsContext.LR.getParam(“item”)) – select an item based on the parameter item

Replay step synchronization guidelines
If there are no failures, stick with defaults.
Make changes only if
• The script is not running correctly
• To measure transaction response time using different end events
(and you know what you are doing )
Possible workarounds:
•
•
•
•
•
45
Change end event
Increase object timeout
Increase step timeout
Increase network timeout (in RTS)
Add wait steps
