read data from a database or text file in instruments javascript script

问题

I have a script like so:

var target = UIATarget.localTarget();
var mainWindow = target.frontMostApp().mainWindow();

var element = mainWindow.textFields()["UserID"];
element.setValue("Hello World");

UIALogger.logStart("Logging element tree ...");
target.logElementTree();
UIALogger.logPass();

What I want to do is read a text file or database connection, so I can replace the "Hello World" with either a value from a text file or a database query. Is this possible in the Instruments application with using javascript to control UI Automation for the iphone simulator?

回答1:

Yes it is possible. You can acquire every data that you are able to acquire in a bash script. Write a script file that prints the desired information to the standard output. For example

#!/bin/bash
cat myfile

You can run this bash-script from UIAutomation and get the output of it with this command

var result = target.host().performTaskWithPathArgumentsTimeout(full_path_to_your_script, [""], 10);

Now your can use the output of your bash script:

element.setValue(result.stdout);
