I have a selenium test that works great while debugging and stepping slowly through. I added a Thread.Sleep() in order to stop selenium while a file is downloaded. However selenium in completely ignoring the Thread.Sleep(). Any thoughts?
IWebElement iframe = driver.FindElement(By.Id("genFrame"));
CurrentFrame = driver.SwtichTo();
CurrentFrame.Frame(iframe);
driver.FindElement(By.Id("date").Sendkeys("05/11/2021" + Keys.Enter));
driver.FindElement(By.Id("export-btn"));
System.Thread.Sleep(5000);
In all possibilities System.Thread.Sleep() is never ignored unless some previous line of code raises an exception.
As per your code the unit is milliseconds, so effectively 5000 milliseconds, i.e. 5 seconds.
Solution
You may like to increase the waiting time to greater value, e.g. 10 seconds or more:
using System;
using System.Threading;
System.Thread.Sleep(10000);
Update
As you can visually see selenium add the date field, possibly the line in the mid:
driver.FindElement(By.Id("export-btn"));
raises an exception.
I wants to apply dynamic wait in ranorex.
To open a webpage I used static wait like this :-
Host.Local.OpenBrowser("http://www.ranorex.com/Documentation/Ranorex/html/M_Ranorex_WebDocument_Navigate_2.htm",
"firefox.exe");
Delay.Seconds(15);
Please provide me a proper solution in details. Waiting for your humble reply.
The easiest way is use the wait for document loaded method. This allows you to set a timeout that is the maximum to wait, but will continue when the element completes it's load. Here is the documentation on it,
http://www.ranorex.com/Documentation/Ranorex/html/M_Ranorex_WebDocument_WaitForDocumentLoaded_1.htm
First of all, you should be more detailed about your issues. Atm you actually don't state any issue and don't even specify the reason for the timeout.
I don't actually see why you would need a timeout there. The next element to be interacted with in your tests will have it's own search timeouts. In my experience I haven't had a need or a reason to have a delay for the browser opening.
If you truelly need a dynamic delay there, here's what you actually should validate.
1) Either select an element that always exists on the webpage when you open the browser or
2) Select the next element to be interacted with and build the delay ontop of either of these 2
Let's say that we have a Input field that we need to add text to after the page has opened. The best idea would be do wait for that element to exists and then continue with the test case.
So, we wait for the element to exist (add the element to the repository):
repo.DomPart.InputElementInfo.WaitForExists(30000);
And then we can continue with the test functionality:
repo.DomPart.InputElement.InnerText = "Test";
What waitForExists does is it waits for 30 seconds (30000 ms) for the element to exists. It it possible to catch an exception from this and add error handleing if the element is not found.
The dynamic functionality has to be added by you. In ranorex at one point you will always run into a timeout. It might be a specified delay, it might be the timeout for a repo element, etc. The "dynamic" functionality is mostly yours to do.
If this is not the answer you were looking for, please speicify the reason for the delay and i'll try to answer your specific issue more accurately.
Please bear with me as I am relatively new to Appium. I am writing C# tests in Appium for my Android app. I am stuck finding answers to questions below.
1) How to check if a particular element exists? Is there any boolean property or function returning true or false? The methods driver.GetElementById, driver.GetElementByName etc. throw exceptions if element doesn't exists.
2) Suppose I want to write a test for login. The user enters username and password and hits login button. The requests goes to server and it checks whether username-password pair exists in database. Meanwhile the loading indicator (progress dialog in Android) is shown on screen. How shall make a test suspend it's execution until response comes from server assuming I don't want to use something like Thread.Sleep function?
3) Can I check whether textfield validation is failed on screen? A control with black background and white text is shown below textfield upon validation failure if we set validation for that textfield through setError function. Is there any way to check that validation has failed?
Anticipating answers. Thanks.
For the first 2 questions (This is what I do in java, definitely can be implemented in c#) -
1) Use the polling technique - In a loop check for the element return of the following
#param - By by , int time
driver.findElement(By by);
This must not be null or empty.
If within the threshhold time the element is not present then fail the test.
In appium mode - isVisible() will be same as the above, as an element not visible will not be present.
2) Check for the next activity to be awaited. Use the same polling technique to keep on comparing the current activity with the awaited activity, If the awaited activity does not start within the threshold time then fail the test.
#param int time, String awaitedActivity
1) Get the current activity.
2) Compare with the awaited activity.
3) If same then break the loop.
4) Else sleep for a second and then continue till the time is exhausted.
I am creating a live editor in Windows 8.1 App using JavaScript. Almost done with that, but the problem is whenever I run such bad loops or functions then it automatically hangs or exits.
I test it with a loop such as:( It just a example-user may write its loop in its own way..)
for(i=0;i<=50000;i++)
{
for(j=0;j<5000;j++){
$('body').append('hey I am a bug<br>');
}
}
I know that this is a worst condition for any app or browser to handle that kind of loop. So here I want that if user uses such a loop then how I handle it, to produce their output?
Or if its not possible to protect my app for that kind of loop, if it is dangerous to my app so I alert the user that:
Running this snippet may crash the app!
I have an idea to check the code by using regular expressions if code have something like for(i=0;i<=5000;i++) then the above alert will show, how to do a Regex for that?
Also able to include C# as back-end .
Unfortunately, without doing some deep and complex code analysis of the edited code, you'll not be able to fully prevent errant JavaScript that kills your application. You could use, for example, a library that builds an abstract syntax tree from JavaScript and not allow code execution if certain patterns are found. But, the number of patterns that could cause an infinite loop are large, so it would not be simple to find, and it's likely to not be robust enough.
In the for example, you could modify the code to be like this:
for(i=0;!timeout() && i<=50000;i++)
{
for(j=0;!timeout() && j<5000;j++){
$('body').append('hey I am a bug<br>');
}
}
I've "injected" a call to a function you'd write called timeout. In there, it would need to be able to detect whether the loop should be aborted because the script has been running too long.
But, that could have been written with a do-while, so that type of loop would need to be handled.
The example of using jQuery for example in a tight loop, and modifying the DOM means that solutions that trying to isolate the JavaScript into a Web Worker would be complex, as it's not allowed to manipulate the DOM directly. It can only send/receive "string" messages.
If you had used the XAML/C# WebView to host (and build) the JavaScript editor, you could have considered using an event that is raised called WebView.LongRunningScriptDetected. It is raised when a long running script is detected, providing the host the ability to kill the script before the entire application becomes unresponsive and is killed.
Unfortunately, this same event is not available in the x-ms-webview control which is available in a WinJS project.
I've got 2 solutions:
1.
My first solution would be defining a variable
startSeconds=new Date().getSeconds();.
Then, using regex, I'm inserting this piece of code inside the nested loop.
;if(startSecond < new Date().getSeconds())break;
So, what it does is each time the loop runs, it does two things:
Checks if startSecond is less than current seconds new Date().getSeconds();.
For example, startSecond may be 22. new Date().getSeconds() may return 24.Now, the if condition succeeds so it breaks the loop.
Mostly, a non dangerous loop should run for about 2 to 3 seconds
Small loops like for(var i=0;i<30;i++){} will run fully, but big loops will run for 3 to 4 seconds, which is perfectly ok.
My solution uses your own example of 50000*5000, but it doesn't crash!
Live demo:http://jsfiddle.net/nHqUj/4
2.
My second solution would be defining two variables start, max.
Max should be the maximum number of loops that you are willing to run. Example 1000.
Then, using regex, I'm inserting this piece of code inside the nested loop.
;start+=1;if(start>max)break;
So, what it does is each time the loop runs, it does two things:
Increments the value of start by 1.
Checks whether start is greater than the max. If yes, it breaks the loop.
This solution also uses your own example of 50000*5000, but it doesn't crash!
Updated demo:http://jsfiddle.net/nHqUj/3
Regex I'm using:(?:(for|while|do)\s*\([^\{\}]*\))\s*\{([^\{\}]+)\}
One idea, but not sure what is your editor is capable of..
If some how you can understand that this loop may cause problem(like if a loop is more than 200 times then its a issue) and for a loop like that from user if you can change the code to below to provide the output then it will not hang. But frankly not sure if it will work for you.
var j = 0;
var inter = setInterval( function(){
if( j<5000 ){
$('#test').append('hey I am a bug<br>');
++j;
} else {
clearInterval(inter);
}
}, 100 );
Perhaps inject timers around for loops and check time at the first line. Do this for every loop.
Regex: /for\([^{]*\)[\s]*{/
Example:
/for\([^{]*\)[\s]*{/.test("for(var i=0; i<length; i++){");
> true
Now, if you use replace and wrap the for in a grouping you can get the result you want.
var code = "for(var i=0; i<length; i++){",
testRegex = /(?:for\([^{]*\)[\s]*{)/g,
matchReplace = "var timeStarted = new Date().getTime();" +
"$1" +
"if (new Date().getTime() - timeStarted > maxPossibleTime) {" +
"return; // do something here" +
"}";
code.replace(textRegex, matchReplace);
You cannot find what user is trying to do with a simple regex. Lets say, the user writes his code like...
for(i=0;i<=5;i++)
{
for(j=0;j<=5;j++){
if(j>=3){
i = i * 5000;
j = j * 5000;
}
$('body').append('hey I am a bug<br>');
}
}
Then with a simple regex you cannot avoid this. Because the value of i is increased after a time period. So the best way to solve the problem is to have a benchmark. Say, your app hangs after continuos processing of 3 minutes(Assume, until your app hits 3 minutes of processing time, its running fine). Then, whatever the code the user tries to run, you just start a timer before the process and if the process takes more than 2.5 minutes, then you just kill that process in your app and raise a popup to the user saying 'Running this snippet may crash the app!'... By doing this way you dont even need a regex or to verify users code if it is bad...
Try this... Might help... Cheers!!!
Let's assume you are doing this in the window context and not in a worker. Put a function called rocketChair in every single inner loop. This function is simple. It increments a global counter and checks the value against a global ceiling. When the ceiling is reached rocketChair summarily throws "eject from perilous code". At this time you can also save to a global state variable any state you wish to preserve.
Wrap your entire app in a single try catch block and when rocket chair ejects you can save the day like the hero you are.
I have a, what seems to be, rather common scenario I'm trying to work through.
I have a site that accepts input through two different text fields. If the input is malformed or invalid, I receive a Javascript pop-up notification.
I will not always receive one, but I should in the event of (like I said earlier) malformed data, or when a search result couldn't be found.
How can I detect this in WatiN?
A quick Google search produced results that show how to click through them, but I'm curious as to whether or not I can detect when I get one?
In case anyone is wondering, I'm using WatiN to do some screen scraping for me, rather than integration testing :)
Thanks in advance!
Ian
Here's what I came up with.
I read this question several times before I came up with the obvious solution..
Can I read JavaScript alert box with WatiN?
This is the code I came up with.. While it does force a delay of 3 seconds if the alert doesn't happen, it works perfectly for my scenario.
Hope someone else finds this useful..
frame.Button(Find.ByName("go")).ClickNoWait();
System.Diagnostics.Stopwatch stopwatch = new System.Diagnostics.Stopwatch();
stopwatch.Start();
while (stopwatch.Elapsed.TotalMilliseconds < 3000d)
{
if (alertDialogHandler.Exists())
{
// Do whatever I want to do when there is an alert box.
alertDialogHandler.OKButton.Click();
break;
}
}
