iphone UITesting a button that is a number

Question

I'm trying out UITesting for the iPhone, and I thought I would use the simple rpn calculator from the lecture 2 of stanford's cs193p iTunes U class to run my first tests on.

my javascript is as follows

var target = UIATarget.localTarget();

target.frontMostApp().mainWindow().buttons()["3"].tap();
target.frontMostApp().mainWindow().buttons()["Enter"].tap();
target.frontMostApp().mainWindow().buttons()["4"].tap();
target.frontMostApp().mainWindow().buttons()["/"].tap();

var display = target.frontMostApp().mainWindow().staticTexts()[1].value();
if (display == "0.75") {
    UIALogger.logPass("3 E 4 /");
} else {
    UIALogger.logFail("3 E 4 /");
}

However the script runs sin enter cos / In the editor log it is showing

target.frontMostApp().mainWindow().buttons()[3].tap();
target.frontMostApp().mainWindow().buttons()["Enter"].tap();
target.frontMostApp().mainWindow().buttons()[4].tap();
target.frontMostApp().mainWindow().buttons()["/"].tap();

So somehow instruments is converting my string "3" into the index 3 and then tapping the third button.

So I could call the buttons by their index number, but I would much prefer to call them by their text.

It's a limitation with using brackets to access UIAElementArray's that numbers get treated as an indices. 8-(.

Instead just add firstWithName():

target.frontMostApp().mainWindow().buttons().firstWithName("3").tap();

See UIAElementArray Class Reference
