I am facing Synchronization issues even though I am using Explicit Wait and Implicit wait in my script. So I am using customized waitForAngularRequestTofinish method as shown below.
public void waitForAngularRequestToFinish()
{
var js = (IJavaScriptExecutor)driver;
string javaScriptToLoadAngular = "return (window.getAllAngularTestabilities()[0]._ngZone.hasPendingMicrotasks == " +
"false && " +
"window.getAllAngularTestabilities()[0]._ngZone.hasPendingMacrotasks == false && " +
"window.getAllAngularTestabilities()[0]._ngZone._nesting == 0 &&" +
"window.getAllAngularTestabilities()[0]._ngZone.isStable == true &&" +
"window.document.readyState == 'complete'" +
")";
// string javaScriptToLoadAngular = "return (window.getAngularTestability(window.getAllAngularRootElements()[0]).isStable())";
WebDriverWait wt = new WebDriverWait(driver, TimeSpan.FromSeconds(100));
wt.Until<bool>(
(d) =>
{
return (bool)js.ExecuteScript(javaScriptToLoadAngular).Equals(true);
});
}
However it is taking so much of time, that single scenario is taking almost 15 minutes to execute. I need a solution where i can reduce my execution time.
And also from past 10 days, hasPendingMacroTasks is never set to false in my application, because of that i am unable to execute my scripts at all.

I'm actually developing a project that read data from 19 PLCs Siemens S1500 and 1 modicon. I have used the scraper tool following this tutorial:
PLC4x scraper tutorial
but when the scraper is working for a little amount of time I get the following exception:
I have changed the scheduled time between 1 to 100 and I always get the same exception when the scraper reach the same number of received messages.
I have tested if using PlcDriverManager instead of PooledPlcDriverManager could be a solution but the same problem persists.
In my pom.xml I use the following dependency:
<dependency>
<groupId>org.apache.plc4x</groupId>
<artifactId>plc4j-scraper</artifactId>
<version>0.7.0</version>
</dependency>
I have tried to change the version to an older one like 0.6.0 or 0.5.0 but the problem still persists.
If I use the modicon (Modbus TCP) I also get this exception after a little amount of time.
Anyone knows why is happening this error? Thanks in advance.
Edit: With the scraper version 0.8.0-SNAPSHOT I continue having this problem.
Edit2: This is my code, I think the problem can be that in my scraper I am opening a lot of connections and when it reaches 65526 messages it fails. But since all the processing is happenning inside the lambda function and I'm using a PooledPlcDriverManager, I think the scraper is using only one connection so I dont know where is the mistake.
try {
// Create a new PooledPlcDriverManager
PlcDriverManager S7_plcDriverManager = new PooledPlcDriverManager();
// Trigger Collector
TriggerCollector S7_triggerCollector = new TriggerCollectorImpl(S7_plcDriverManager);
// Messages counter
AtomicInteger messagesCounter = new AtomicInteger();
// Configure the scraper, by binding a Scraper Configuration, a ResultHandler and a TriggerCollector together
TriggeredScraperImpl S7_scraper = new TriggeredScraperImpl(S7_scraperConfig, (jobName, sourceName, results) -> {
LinkedList<Object> S7_results = new LinkedList<>();
messagesCounter.getAndIncrement();
S7_results.add(jobName);
S7_results.add(sourceName);
S7_results.add(results);
logger.info("Array: " + String.valueOf(S7_results));
logger.info("MESSAGE number: " + messagesCounter);
// Producer topics routing
String topic = "s7" + S7_results.get(1).toString().substring(S7_results.get(1).toString().indexOf("S7_SourcePLC") + 9 , S7_results.get(1).toString().length());
String key = parseKey_S7("s7");
String value = parseValue_S7(S7_results.getLast().toString(),S7_results.get(1).toString());
logger.info("------- PARSED VALUE -------------------------------- " + value);
// Create my own Kafka Producer
ProducerRecord<String, String> record = new ProducerRecord<String, String>(topic, key, value);
// Send Data to Kafka - asynchronous
producer.send(record, new Callback() {
public void onCompletion(RecordMetadata recordMetadata, Exception e) {
// executes every time a record is successfully sent or an exception is thrown
if (e == null) {
// the record was successfully sent
logger.info("Received new metadata. \n" +
"Topic:" + recordMetadata.topic() + "\n" +
"Partition: " + recordMetadata.partition() + "\n" +
"Offset: " + recordMetadata.offset() + "\n" +
"Timestamp: " + recordMetadata.timestamp());
} else {
logger.error("Error while producing", e);
}
}
});
}, S7_triggerCollector);
S7_scraper.start();
S7_triggerCollector.start();
} catch (ScraperException e) {
logger.error("Error starting the scraper (S7_scrapper)", e);
}
So in the end indeed it was the PLC that was simply hanging up the connection randomly. However the NiFi integration should have handled this situation more gracefully. I implemented a fix for this particular error ... could you please give version 0.8.0-SNAPSHOT a try (or use 0.8.0 if we happen to have released it already)
I am using Selenium IDE to test a web based HR/SW system.
There is a screen that used to enter vacation for employees.
I am having nearly 3000 employee.
I built a test case that enter vacations for one employee using variables.
How can I repeat the test case for all 3000 employees without creating the test case 3000 times. It will take an impossible effort to do that. Note: Each employee is having different vacation data (Type, start date, End date)
Is there any way that I can use a file (Excel,....) that variable can use to read its data from?
Is there any solution for my case???
I will be very very grateful I any one could help me.
Thank you.
You could use an XML file as an input.
1) At first you have to add following user extensions:
sideflow.js - (http://51elliot.blogspot.com/2008/02/selenium-ide-goto.html - additionally this article explains how to add user extension files)
datadriven.js
include.js
At the moment I can't find links where I took the last two, therefore I will give their code in the end of my post. Code is taken from my working directory. You just put the code to correspondent files, then add files to SelemiunIDE user extension and use them.
2) Create an XML file test_data.xml:
<testdata>
<test employee="1" type="1" startDate="01.01.2013" endDate="01.02.2013" />
<test employee="2" type="1" startDate="01.02.2013" endDate="01.03.2013" />
<test employee="3" type="1" startDate="01.03.2013" endDate="01.04.2013" />
...
</testdata>
3) In your test case use code like this:
${DataPath} - full path to a directory with XML-files
<!--BEGIN LOOP-->
<tr>
<td>loadTestData</td>
<td>file://${DataDir}/test_data.xml</td>
<td></td>
</tr>
<tr>
<td>while</td>
<td>!testdata.EOF()</td>
<td></td>
</tr>
<tr>
<td>nextTestData</td>
<td></td>
<td></td>
</tr>
<tr>
<td>echo</td>
<td>employee=${employee} type=${type} ...</td>
<td></td>
</tr>
...
<!--END LOOP-->
<tr>
<td>endWhile</td>
<td></td>
<td></td>
</tr>

Current solution is a SelBlocks component which allows you to do cycles according to the dataset in XML
ForXML | XMLFileName.XML
... test case steps
EndForXML
The XML should have specific structure
<testdata>
<vars storedVariable1="xxxxx" storedVariable2="yyyyy" .. storedVariableN="zzzzz" />
.. other record(s)
</testdata>
Each stored variable vill be available in test case as ${storedVariableN}.
You can produce XML by MS Excel or LibreOffice using Formulas like this one and copy it to whole table:
="<vars "&
" "&$A$1&"="""&A2&""" "&
" "&$B$1&"="""&B2&""" "&
..
" "&$X$1&"="""&X2&""" "&
"/>")
XML can be easily copypasted after each change of the dataset.
Selblocks contains the while, datadriven, goto, loop and other extensions mentioned in previous answers. You can use other functionalities of the Selblocks as conditional jumps, conditions, catch-try blocks, functions, etc. See full reference here: http://refactoror.wikia.com/wiki/Selblocks_Reference
Beware with new Selenium 3 release and Sel Core absence it is not guaranteed, that tests with Selblock addon will work in the future versions of the firefox.
You can also check this very nice blog article:
http://seleniumworks.blogspot.com/2014/01/selenium-ide-data-driven.html
This gives an explanation on how to use the needed plugins and where to download them from. It worked perfectly for me.
This answer pretty much has the same approach as the one provided by #Yevgen Ulyanenkov as I used his answer in order to find the above article. But has some more googling to it that hopefully will be helpful to someone.
I think you need to use loop I don't see your code so just check this one for selenium-ide loop If you have any more problem if so comment my answer. I can't comment into your question because reputation is not enough so. If possible please add your code into your question.
I am trying to write a big project which involves of a lot of code. That's why I want to separate functionalities from different files.
the first file, dataJS, I make an AJAX call to get data from a JSON file.
the second file, showJS I want to display the data obtained from the dataJS file.
When it comes to implementation, I realise that AJAX call takes longer time and even though I include dataJS and showJS in order, showJS will still get a null data
therefore I made a function called continueFromDataJS() in showJS file
and call continueFromDataJS() at the end of the AJAX success function.
I think it's a rather makedo solution. Is there any standard way to do it?
In addition, all intellisense in my Visual Studio is gone. Despite separate files, is there any way to make visual studio get intellisense from the dataJS?
Thank you
sorry, I don't know how to add a follow up question
this is the code
for simplicity I rename some of the files and only take some part out of it. Hope that helps

var gsc = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService") as IGeocodeService;
Location returnLocation = new Location();
GeocodeResponse gcResp = new GeocodeResponse();
GeocodeRequest gcr = new GeocodeRequest();
gcr.Credentials = new Credentials();
gcr.Credentials.ApplicationId = APP_ID2;
gcr.Query = Address1;
var myFunc = Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>(gsc.BeginGeocode, gsc.EndGeocode);
gcResp = myFunc(gcr) as GeocodeResponse;
if (gcResp.Results.Count > 0 && gcResp.Results[0].Locations.Count > 0)
{
returnLocation = gcResp.Results[0].Locations[0];
}
return returnLocation as IObservable<Location>;
}
gcResp comes back as null. Any thoughts or suggestions would be greatly appreciated.
The observable source you are subscribing to is asynchronous, so you can't access the result immediately after subscribing. You need to access the result in the subscription.
Better yet, don't subscribe at all and simply compose the response:
private IObservable<Location> GetGPSCoordinates(string Address1)
{
IGeocodeService gsc =
new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");
Location returnLocation = new Location();
GeocodeResponse gcResp = new GeocodeResponse();
GeocodeRequest gcr = new GeocodeRequest();
gcr.Credentials = new Credentials();
gcr.Credentials.ApplicationId = APP_ID2;
gcr.Query = Address1;
var factory = Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>(
gsc.BeginGeocode, gsc.EndGeocode);
return factory(gcr)
.Where(response => response.Results.Count > 0 &&
response.Results[0].Locations.Count > 0)
.Select(response => response.Results[0].Locations[0]);
}
If you only need the first valid value (the location of the address is unlikely to change), then add a .Take(1) between the Where and Select.
Edit: If you want to specifically handle the address not being found, you can either return results and have the consumer deal with it or you can return an Exception and provide an OnError handler when subscribing. If you're thinking of doing the latter, you would use SelectMany:
return factory(gcr)
.SelectMany(response => (response.Results.Count > 0 &&
response.Results[0].Locations.Count > 0)
? Observable.Return(response.Results[0].Locations[0])
: Observable.Throw<Location>(new AddressNotFoundException())
);
If you expand out the type of myFunc you'll see that it is Func<GeocodeRequest, IObservable<GeocodeResponse>>.
Func<GeocodeRequest, IObservable<GeocodeResponse>> myFunc =
Observable.FromAsyncPattern<GeocodeRequest, GeocodeResponse>
(gsc.BeginGeocode, gsc.EndGeocode);
So when you call myFunc(gcr) you have an IObservable<GeocodeResponse> and not a GeocodeResponse. Your code myFunc(gcr) as GeocodeResponse returns null because the cast is invalid.
What you need to do is either get the last value of the observable or just do a subscribe. Calling .Last() will block. If you call .Subscribe(...) your response will come thru on the call back thread.
Try this:
gcResp = myFunc(gcr).Last();
Let me know how you go.
Richard (and others),
So I have the code returning the location and I have the calling code subscribing. Here is (hopefully) the final issue. When I call GetGPSCoordinates, the next statement gets executed immediately without waiting for the subscribe to finish. Here's an example in a button OnClick event handler.
Location newLoc = new Location();
GetGPSCoordinates(this.Input.Text).ObserveOnDispatcher().Subscribe(x =>
{
if (x.Results.Count > 0 && x.Results[0].Locations.Count > 0)
{
newLoc = x.Results[0].Locations[0];
Output.Text = "Latitude: " + newLoc.Latitude.ToString() +
", Longtude: " + newLoc.Longitude.ToString();
}
else
{
Output.Text = "Invalid address";
}
});
Output.Text = " Outside of subscribe --- Latitude: " + newLoc.Latitude.ToString() +
", Longtude: " + newLoc.Longitude.ToString();
The Output.Text assignment that takes place outside of Subscribe executes before the Subscribe has finished and displays zeros and then the one inside the subscribe displays the new location info.
The purpose of this process is to get location info that will then be saved in a database record and I am processing multiple addresses sequentially in a Foreach loop. I chose Rx Extensions as a solution to avoid the problem of the async callback as a coding trap. But it seems I have exchanged one trap for another.
Thoughts, comments, suggestions?
What is the most convenient way using Selenium WebDriver to check if an URL GET returns successfully (HTTP 200)?
In this particular case I'm most interested in verifying that no images of the current page are broken.
Try this:
List<WebElement> allImages = driver.findElements(By.tagName("img"));
for (WebElement image : allImages) {
boolean loaded = ((JavaScriptExecutor) driver).executeScript(
"return arguments[0].complete", image);
if (!loaded) {
// Your error handling here.
}
}
You could use the getEval command to verify the value returned from the following JavaScript for each image on the page.
#Test
public void checkForBrokenImages() {
selenium.open("http://www.example.com/");
int imageCount = selenium.getXpathCount("//img").intValue();
for (int i = 0; i < imageCount; i++) {
String currentImage = "this.browserbot.getUserWindow().document.images[" + i + "]";
assertEquals(selenium.getEval("(!" + currentImage + ".complete) ? false : !(typeof " + currentImage + ".naturalWidth != \"undefined\" && " + currentImage + ".naturalWidth == 0);"), "true", "Broken image: " + selenium.getEval(currentImage + ".src"));
}
}
Updated:
Added tested TestNG/Java example.
I don't think that first response will work. When I src a misnamed image, it throws a 404 error as expected. However, when I check the javascript in firebug, that (broken) image has .complete set to true. So, it was a completed 404, but still a broken image.
The second response seems to be more accurate in that it checks that it's complete and then checks that there is some width to the image.
I made a python version of the second response that works for me. Could be cleaned up a bit, but hopefully it will help.
def checkForBrokenImages(self):
sel = self.selenium
imgCount = int(sel.get_xpath_count("//img"))
for i in range(0,imgCount):
isComplete = sel.get_eval("selenium.browserbot.getCurrentWindow().document.images[" + str(i) + "].complete")
self.assertTrue(isComplete, "Bad Img (!complete): "+sel.get_eval("selenium.browserbot.getCurrentWindow().document.images[" + str(i) + "].src"))
typeOf = sel.get_eval("typeof selenium.browserbot.getCurrentWindow().document.images[" + str(i) + "].naturalWidth")
self.assertTrue(typeOf != 'undefined', "Bad Img (w=undef): "+sel.get_eval("selenium.browserbot.getCurrentWindow().document.images[" + str(i) + "].src"))
natWidth = int(sel.get_eval("selenium.browserbot.getCurrentWindow().document.images[" + str(i) + "].naturalWidth"))
self.assertTrue(natWidth > 0, "Bad Img (w=0): "+sel.get_eval("selenium.browserbot.getCurrentWindow().document.images[" + str(i) + "].src"))
Instead of traversing in Java, it may be faster to call javascript only once for all images.
boolean allImgLoaded = (Boolean)((JavascriptExecutor) driver).executeScript(
"return Array.prototype.slice.call(document.images).every("
+ "function (img) {return img.complete && img.naturalWidth > 0;});");
One of the alternative solutions is analyzing web server logs after test executing. This approach allows to catch not only missed images, but css, scripts and other resources.
Description of how to do it is here.
Funda for Checking 404:
Basically 404s can be checked via HTTP Response of the URL.
Step 1: Import the Library for HTTPTestAPI
Step 2: Create the HTTPRequest.
String URL="www.abc.com";
HTTPRequest request = new HTTPRequest(URL);
//Get the response code of the URL
int response_code = request.getResponseCode();
//Check for 404:
if(response_code == 404)
FAIL -- THE URL is leading to 404.
else
PASS
