Java and Javascript - Lastmodified on Linux

I wrote a script on the Jmeter Web Driver in javascript and Java .
On a Windows system , the script is running perfectly . But on a Linux System , i have a weird problem . The lastmodifed then i obtain is not good. front_end.jtl has been modified yesterday , but the script say today at 10:00 in milliseconds timestamp .
Please help me.
// Importing packages (and all classes in package) from Java into Javascript var pkg = JavaImporter(org.openqa.selenium)
var support_ui = JavaImporter(org.openqa.selenium.support.ui.WebDriverWait)
// We don't use wait in this very simple test, but here is way to access for more realistic testing
var wait=new support_ui.WebDriverWait(WDS.browser, 5)
// Start recording the time for this request
WDS.sampleResult.sampleStart();
// Let's get a page
var baseUrl = "cnyw${FE}.mycore.core-cloud.net"
WDS.browser.get("https://"+ baseUrl)
var frontjtl = new java.io.File('/home/mycore/front_end.jtl')
var frontlog = new java.io.File('/home/mycore/jmeter_front_end.log')
var lastmodifjtl = frontjtl.lastModified()
var lastmodiflog = frontlog.lastModified()
if ( lastmodifjtl = lastmodiflog ) {
var screenshot = WDS.browser.getScreenshotAs(pkg.OutputType.FILE)
screenshot.renameTo(new java.io.File('/home/mycore/screenshots/tools/screenshot_cnyw${FE}.png'))
}
// Record the time of the request
WDS.sampleResult.sampleEnd();

I would recommend using Files.getLastModifiedTime() instead, something like:
var lastmodifjtl = java.nio.file.Files.getLastModifiedTime(java.nio.file.Paths.get(frontjtl.toURI()))
should do the trick for you.

I found an explanation : https://bugs.openjdk.java.net/browse/JDK-8177809
It's a confirmed bug ...

i have rewrite the script in Java directly. All is okay now.

How to read and write to a file (Javascript) in ui automation?

I want to identify few properties during my run and form a json object which I would like to write to a ".json"file and save it on the disk.
var target = UIATarget.localTarget();
var properties = new Object();
var jsonObjectToRecord = {"properties":properties}
jsonObjectToRecord.properties.name = "My App"
UIALogger.logMessage("Pretty Print TEST Log"+jsonObjectToRecord.properties.name);
var str = JSON.stringify(jsonObjectToRecord)
UIALogger.logMessage(str);
// -- CODE TO WRITE THIS JSON TO A FILE AND SAVE ON THE DISK --
I tried :
// Sample code to see if it is possible to write data
// onto some file from my automation script
function WriteToFile()
{
set fso = CreateObject("Scripting.FileSystemObject");
set s = fso.CreateTextFile("/Volumes/DEV/test.txt", True);
s.writeline("HI");
s.writeline("Bye");
s.writeline("-----------------------------");
s.Close();
}
AND
function WriteFile()
{
// Create an instance of StreamWriter to write text to a file.
sw = new StreamWriter("TestFile.txt");
// Add some text to the file.
sw.Write("This is the ");
sw.WriteLine("header for the file.");
sw.WriteLine("-------------------");
// Arbitrary objects can also be written to the file.
sw.Write("The date is: ");
sw.WriteLine(DateTime.Now);
sw.Close();
}
But still unable to read and write data to file from ui automation instruments
Possible Workaround ??
To redirect to the stdout if we can execute a terminal command from my ui automation script. So can we execute a terminal command from the script ?
Haven't Tried :
1. Assuming we can include the library that have those methods and give it a try .

Your assumptions are good, But the XCode UI Automation script is not a full JavaScript.
I don't think you can simply program a normal browser based JavaScript in the XCode UI Automation script.
set fso = CreateObject("Scripting.FileSystemObject");
Is not a JavaScript, it is VBScript which will only work in Microsoft Platforms and testing tools like QTP.
Scripting.FileSystemObject
Is an ActiveX object which only exists in Microsoft Windows
Only few JavaScript functions like basic Math, Array,...etc..Are provided by the Apple JavaScript library, so you are limited to use only the classes provided here https://developer.apple.com/library/ios/documentation/DeveloperTools/Reference/UIAutomationRef/
If you want to do more scripting then Try Selenium IOS Driver http://ios-driver.github.io/ios-driver/

Hey so this is something that I was looking into for a project but never fully got around to implementing so this answer will be more of a guide of what to do than step by step copy and paste.
First you're going to need to create a bash script that writes to a file. This can be as simple as
!/bin/bash
echo $1 >> ${filename.json}
Then you call this from inside your Xcode Instruments UIAutomation tool with
var target = UIATarget.localTarget();
var host = target.host();
var result = host.performTaskWithPathArgumentsTimeout("your/script/path", ["Object description in JSON format"], 5);
Then after your automation ends you can load up the file path on your computer to look at the results.
EDIT: This will enable to write to a file line by line but the actual JSON formatting will be up to you. Looking at some examples I don't think it would be difficult to implement but obviously you'll need to give it some thought at first.

What's the best method to EXTRACT product names given a list of SKU numbers from a website?

I have a problem.
I have a list of SKU numbers (hundreds) that I'm trying to match with the title of the product that it belongs to. I have thought of a few ways to accomplish this, but I feel like I'm missing something... I'm hoping someone here has a quick and efficient idea to help me get this done.
The products come from Aidan Gray.
Attempt #1 (Batch Program Method) - FAIL:
After searching for a SKU in Aidan Gray, the website returns a URL that looks like below:
http://www.aidangrayhome.com/catalogsearch/result/?q=SKUNUMBER
... with "SKUNUMBER" obviously being a SKU.
The first result of the webpage is almost always the product.
To click the first result (through the address bar) the following can be entered (if Javascript is enabled through the address bar):
javascript:{document.getElementsByClassName("product-image")[0].click;}
I wanted to create a .bat file through Command Prompt and execute the following command:
firefox http://www.aidangrayhome.com/catalogsearch/result/?q=SKUNUMBER javascript:{document.getElementsByClassName("product-image")[0].click;}
... but Firefox doesn't seem to allow these two commands to execute in the same tab.
If that worked, I was going to go to http://tools.buzzstream.com/meta-tag-extractor, paste the resulting links to get the titles of the pages, and export the data to CSV format, and copy over the data I wanted.
Unfortunately, I am unable to open both the webpage and the Javascript in the same tab through a batch program.
Attempt #2 (I'm Feeling Lucky Method):
I was going to use Google's &btnI URL suffix to automatically redirect to the first result.
http://www.google.com/search?btnI&q=site:aidangrayhome.com+SKUNUMBER
After opening all the links in tabs, I was going to use a Firefox add-on called "Send Tab URLs" to copy the names of the tabs (which contain the product names) to the clipboard.
The problem is that most of the results were simply not lucky enough...
If anybody has an idea or tip to get this accomplished, I'd be very grateful.

I recommend using JScript for this. It's easy to include as hybrid code in a batch script, its structure and syntax is familiar to anyone comfortable with JavaScript, and you can use it to fetch web pages via XMLHTTPRequest (a.k.a. Ajax by the less-informed) and build a DOM object from the .responseText using an htmlfile COM object.
Anyway, challenge: accepted. Save this with a .bat extension. It'll look for a text file containing SKUs, one per line, and fetch and scrape the search page for each, writing info from the first anchor element with a .className of "product-image" to a CSV file.
#if (#CodeSection == #Batch) #then
#echo off
setlocal
set "skufile=sku.txt"
set "outfile=output.csv"
set "URL=http://www.aidangrayhome.com/catalogsearch/result/?q="
rem // invoke JScript portion
cscript /nologo /e:jscript "%~f0" "%skufile%" "%outfile%" "%URL%"
echo Done.
rem // end main runtime
goto :EOF
#end // end batch / begin JScript chimera
var fso = WSH.CreateObject('scripting.filesystemobject'),
skufile = fso.OpenTextFile(WSH.Arguments(0), 1),
skus = skufile.ReadAll().split(/\r?\n/),
outfile = fso.CreateTextFile(WSH.Arguments(1), true),
URL = WSH.Arguments(2);
skufile.Close();
String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ''); }
// returns a DOM root object
function fetch(url) {
var XHR = WSH.CreateObject("Microsoft.XMLHTTP"),
DOM = WSH.CreateObject('htmlfile');
WSH.StdErr.Write('fetching ' + url);
XHR.open("GET",url,true);
XHR.setRequestHeader('User-Agent','XMLHTTP/1.0');
XHR.send('');
while (XHR.readyState!=4) {WSH.Sleep(25)};
DOM.write(XHR.responseText);
return DOM;
}
function out(what) {
WSH.StdErr.Write(new Array(79).join(String.fromCharCode(8)));
WSH.Echo(what);
outfile.WriteLine(what);
}
WSH.Echo('Writing to ' + WSH.Arguments(1) + '...')
out('sku,product,URL');
for (var i=0; i<skus.length; i++) {
if (!skus[i]) continue;
var DOM = fetch(URL + skus[i]),
anchors = DOM.getElementsByTagName('a');
for (var j=0; j<anchors.length; j++) {
if (/\bproduct-image\b/i.test(anchors[j].className)) {
out(skus[i]+',"' + anchors[j].title.trim() + '","' + anchors[j].href + '"');
break;
}
}
}
outfile.Close();
Too bad the htmlfile COM object doesn't support getElementsByClassName. :/ But this seems to work well enough in my testing.

Javascript - reading in a file and iterating over sentences

I'm trying to read in a local text file to perform functions like counting syllables, characters etc.,
I am trying to do this by doing:
var txtFile = new XMLHttpRequest();
txtFile.open("GET", "file://path/to/my/file.txt", true);
txtFile.onreadystatechange = function() {
if (txtFile.readyState === 4) { // Makes sure the document is ready to parse.
if (txtFile.status === 200) { // Makes sure it's found the file.
allText = txtFile.responseText;
//lines = txtFile.responseText.split("\r\n"); // Will separate each line into an array
} //"\r\n"
}
}
when I try to log 'txtFile' to the command line it prints [ObjectHtmlRequest], how do i look at what i'm loading and consequently iterate over it?
I also get an error message when i try doing this piece of code
var text = txtFile
//$(this).val();
//document.text_input.my_text.value = newtext;
var words = new Array(text.replace(/\s/g, ' ').split(' '));
which worked before, but i'm guessing it's not now because i'm no longer working with text

Most browsers won't allow JavaScript to use the local filesystem. Chrome definitely won't, I'm not sure about Firefox and the others.
What I do in that case is either :
Use a local web server based on the local directory if the file you want to read is static. I usually start it with python -mhttp.server (Python 3) or python -mSimpleHTTPServer (Python 2).
Use the latest HTML5 File API if you want to let the user choose the file. More information here.
EDIT: Well, what I said isn't entirely true. Chrome allows you to use local files, but you have to start it on the command line with a special switch (--allow-file-access-from-files), and frankly, it's a bother and is only really intended for development. Don't rely on it for anything in production!

WIX: Where and how should my CustomAction create and read a temporary file?

I have a script CustomAction (Yes, I know all about the opinions that say don't use script CustomActions. I have a different opinion.)
I'd like to run a command, and capture the output. I can do this using the WScript.Shell COM object, then invoking shell.Exec(). But, this flashes a visible console window for the executed command.
To avoid that, I understand I can use the shell.Run() call, and specify "hidden" for the window appearance. But .Run() doesn't give me access to the StdOut of the executed process, so that means I'd need to create a temporary file and redirect the exe output to the temp file, then later read that temp file in script.
Some questions:
is this gonna work?
How do I generate a name for the temporary file? In .NET I could use a static method in the System.IO namespace, but I am using script here. I need to insure that the use has RW access, and also that no anti-virus program is going to puke on this.
Better ideas? I am trying very hard to avoid C/C++.
I could avoid all this if there were a way to query websites in IIS7 from script, without resorting to the IIS6 Compatibility pack, without using .NET (Microsoft.Web.Administration.ServerManager), and without execing a process (appcmd list sites).
I already asked a separate question on that topic; any suggestions on that would also be appreciated.

Answering my own question...
yes, this is going to work.
Use the Scripting.FileSystemObject thing within Javascript. There's a GetTempName() method that produces a file name suitable for temporary use, and a GetSpecialFolder() method that gets the location of the temp folder. There's even a BuildPath() method to combine them.
so far I don't have any better ideas.
Here's the code I used:
function GetWebSites_IIS7_B()
{
var ParseOneLine = function(oneLine) {
...regex parsing of output...
};
LogMessage("GetWebSites_IIS7_B() ENTER");
var shell = new ActiveXObject("WScript.Shell");
var fso = new ActiveXObject("Scripting.FileSystemObject");
var tmpdir = fso.GetSpecialFolder(SpecialFolders.TemporaryFolder);
var tmpFileName = fso.BuildPath(tmpdir, fso.GetTempName());
var windir = fso.GetSpecialFolder(SpecialFolders.WindowsFolder);
var appcmd = fso.BuildPath(windir,"system32\\inetsrv\\appcmd.exe") + " list sites";
// use cmd.exe to redirect the output
var rc = shell.Run("%comspec% /c " + appcmd + "> " + tmpFileName, WindowStyle.Hidden, true);
// WindowStyle.Hidden == 0
var ts = fso.OpenTextFile(tmpFileName, OpenMode.ForReading);
var sites = [];
// Read from the file and parse the results.
while (!ts.AtEndOfStream) {
var oneLine = ts.ReadLine();
var line = ParseOneLine(oneLine);
LogMessage(" site: " + line.name);
sites.push(line);
}
ts.Close();
fso.DeleteFile(tmpFileName);
return sites;
}
