Inject JS Script (JavaScript) behaves differently in Internet Explorer and Chrome

[KannanSuresh]

Scenario:

I am trying to inject same JavaScript to both Internet Explorer and Chrome. Script is a simple one that returns number value 1. See the script below.

function return1(){
    return 1;
}

Same activity works fine with IE and results in an error when tried with chrome. See the details below.

Steps to reproduce:

• Start a new process.
• Create a variable jsReturnValueFromIE of type Int32.
• Create a variable jsReturnValueFromChrome of type Int32.
• Add open browser activity and choose IE as browser type.
• Add Insert JS Script Activity and set the script provided in the scenario section.
• Set ScriptOutPut to jsReturnValueFromIE.
• Add open browser activity and choose Chrome as browser type.
• Add Insert JS Script Activity and set the script provided in the scenario section.
• Set ScriptOutPut to jsReturnValueFromChrome.

Current Behavior:

Insert JS Script Activity with IE returns the integer value 1 and stores in jsReturnValueFromIE.
Insert JS Script Activity with Chrome results in an error - Message: is not a valid value for Int32.

According to official documentation, output of Insert JS Script, ScriptOutPut returns a string.

ScriptOutput - String result returned from JavaScript code.

Expected Behavior:

For both IE and Chrome values should get saved in the respective variables of type Int32.

Comments:

I have tried this with Chrome and IE only. Not sure whether this issue exist in other browsers too.

Hi @KannanSuresh

Thank you for reporting, I’ve added it to our internal bug tracker.
I’ve also tested it with the beta UiAutomation pacakge and it continues to give such result.
