I have created an ActionCable channel using rails generate channel conversation speak, then added something like the below code at the end of conversation.coffe:
$ ->
$("button").click (event) ->
alert()
App.conversation.speak("main", event.target.value)
This works as intended and creates a new comment, along with a button that will spawn new comments. The appended button does not fire the above code though. I am using a comment partial and it works only on refreshing the page.
In the end I changed the code detection in my coffee to
$(document).on 'click', '[data-attribute]', (event) ->

I am new to writing test cases using protractor for non angular application. I wrote a sample test case.Here the browser closes automatically after running test case.How can I prevent this. Here is my code
var submitBtnElm = $('input[data-behavior=saveContribution]');
it('Should Search', function() {
browser.driver.get('http://localhost/enrollments/osda1.html');
browser.driver.findElement(by.id('contributePercentValue')).sendKeys(50);
submitBtnElm.click().then(function() {
});
});
I was also struggling with a similar issue where i had a test case flow where we were interacting with multiple application and when using Protractor the browser was closing after executing one conf.js file. Now when I looked into the previous response it was like adding delay which depends on how quick your next action i performed or it was hit or miss case. Even if we think from debugging perspective most of the user would be performing overnight runs and they would want to have browser active for couple of hours before they analyze the issue. So I started looking into the protractor base code and came across a generic solution which can circumvent this issue, independent of any browser. Currently the solution is specific to requirement that browser should not close after one conf.js file is executed, then could be improved if someone could add a config parameter asking the user whether they want to close the browser after their run.
The browser could be reused for future conf.js file run by using tag --seleniumSessionId in command line.
Solution:
Go to ..\AppData\Roaming\npm\node_modules\protractor\built where your
protractor is installed.
Open driverProvider.js file and go to function quitDriver
Replace return driver.quit() by return 0
As far as my current usage there seems to be no side effect of the code change, will update if I came across any other issue due to this change. Snapshot of code snippet below.
Thanks

Snapshot of code snippet:
Add browser.pause() at the end of your it function. Within the function itself.
I found Gleeson's solution is working, and that really helped me. The solution was...
Go to %APPDATA%Roaming\npm\node_modules\protractor\built\driverProviders\
Find driverProviders.js
Open it in notepad or any other text editor
Find and Replace return driver.Quit() to return 0
Save the file
Restart your tests after that.
I am using
node v8.12.0
npm v6.4.1
protractor v5.4.1
This solution will work, only if you installed npm or protractor globally; if you have installed your npm or protractor locally (in your folder) then, you have to go to your local protractor folder and do the same.
I suggest you to use browser.driver.sleep(500); before your click operation.
See this.
browser.driver.sleep(500);
element(by.css('your button')).click();
browser.driver.sleep(500);
Add a callback function in It block and the browser window doesn't close until you call it.
So perform the action that you need and place the callback at your convenience
var submitBtnElm = $('input[data-behavior=saveContribution]');
it('Should Search', function(callback) {
browser.driver.get('http://localhost/enrollments/osda1.html');
browser.driver.findElement(by.id('contributePercentValue')).sendKeys(50);
submitBtnElm.click().then(function() {
// Have all the logic you need
// Then invoke callback
callback();
});
});
The best way to make browser NOT to close for some time, Use browser.wait(). Inside the wait function write logic for checking either visibilityOf() or invisibilityOf() of an element, which is not visible or it will take time to become invisible on UI. In this case wait() keep on checking the logic until either condition met or timeout reached. You can increase the timeout if you want browser visible more time.
var EC=protractor.ExpectedConditions;
var submitBtnElm = $('input[data-behavior=saveContribution]');
it('Should Search', function() {
browser.driver.get('http://localhost/enrollments/osda1.html');
browser.driver.findElement(by.id('contributePercentValue')).sendKeys(50);
submitBtnElm.click().then(function() {
browser.wait(function(){
EC.invisibilityOf(submitBtnElm).call().then(function(isPresent){
if(isPresent){
return true;
}
});
},20000,'error message');
});
});
I'm sure there is a change triggered on your page by the button click. It might be something as subtle as a class change on an element or as obvious as a <p></p> element with the text "Saved" displayed. What I would do is, after the test, explicitly wait for this change.
[...]
return protractor.browser.wait(function() {
return element(by.cssContainingText('p', 'Saved')).isPresent();
}, 10000);
You could add such a wait mechanism to the afterEach() method of your spec file, so that your tests are separated even without the Protractor Angular implicit waits.
var submitBtnElm = $('input[data-behavior=saveContribution]');
it('Should Search', function() {
browser.driver.get('http://localhost/enrollments/osda1.html');
browser.driver.findElement(by.id('contributePercentValue')).sendKeys(50);
submitBtnElm.click().then(function() {
});
browser.pause(); // it should leave browser alive after test
});
browser.pause() should leave browser alive until you let it go.
#Edit Another approach is to set browser.ignoreSynchronization = true before browser.get(...). Protractor wouldn't wait for Angular loaded and you could use usual element(...) syntax.
Protractor will close browsers, that it created, so an approach that I am using is to start the browser via the webdriver-reuse-session npm package.
DISCLAIMER: I am the author of this package
It is a new package, so let me know if it solves your problem. I am using it with great success.
I have a protractor test that navigates to another url, which cannot be found/resolved in my test environment, so I check if the title is not the previous title.
The test is as follows:
it('should navigate to another site in case of click on cancel link', function () {
page.navigate();
page.submit();
protractor.getInstance().ignoreSynchronization = true;
browser.wait(function(){
return element(by.id('submit')).isPresent();
});
page.closePage();
// the title of a 404, dns issue etc is at least different from the previous site:
expect(browser.getTitle()).not.toEqual('MyDummyTitle')
protractor.getInstance().ignoreSynchronization = false;
});
This works in most browsers, but in Internet Explorer I find that it often is not ready navigating to the non-existing page when the expect is fired.
Can I somehow wait for the 'submit' element to be gone, similar to what I do before firing the closePage?
What I do in this cases is an active wait of an element to disappear:
Using a custom waitAbsent() helper function that actively waits for an element to disappear either by becoming invisible or by not being present.
That helper waits up to specTimeoutMs ignoring useless webdriver errors like StaleElementError.
Usage: add require('./waitAbsent.js'); in your onPrepare block or file.
Example to wait for #submit to be gone:
expect(element(by.id('submit')).waitAbsent()).toBeTruthy();
1-The code below displays the properties of the pressed key.Try it by pressing a key and observe the results.
figure('Name','Press keys to put event data in Command Window',...
'KeyPressFcn',#(obj,evt)disp(evt));
you will see outputs like this( e.g upon pressing space bar)
Character: ' '
Modifier: {1x0 cell}
Key: 'space'
2-Now simply add the following line of code to above ( or simply execute it before clearing the workspace)
cameratoolbar('SetMode','orbit');
Now press any key and nothing happens! the control will no longer be transferred to your costume call back function! ( here:#(obj,evt)disp(evt)).
same thing happens for WindowButtonDownFcn, WindowButtonUpFcn too.
How can I get around this? I wanna be able to handle KeyPressFcn or WindowButtonDownFcn after executing cameratoolbar('SetMode','orbit').
I found the answer: Once the cameratoolbar('SetMode','orbit') is called one of these two happens:the handle to the figure is lost or the event handler gets its default value. I am not sure which one though. Therefore we can add the following code to re-assign the lost handler back to our own call back function:
set(gcf,'KeyPressFcn',#(obj,evt)disp(evt))
Here's my code:
...
if($("input:checked").length > 0) {
chrome.tabs.create(
{url:"http://www.multiculturalyp.com/multiculturalypnewtab.crx"},
function(tab) {
chrome.management.onInstalled.addListener(function(info){alert("Installed A");});
chrome.management.onEnabled.addListener(function(info){alert("Enabled A");});
}
);
chrome.tabs.create(
{url:"instructions.html"},
function(tab) {
chrome.management.onInstalled.addListener(function(info){alert("Installed B");});
chrome.management.onEnabled.addListener(function(info){alert("Enabled B");});
}
);
}
...
So what is happening: I wrote an extension, and if a user so chooses from with that extension's options, a second extension is installed, so I launch instructions in the form of html to tell the user what to click if they really want it installed. I want to hide the instructions (close the instructions tab) automatically ones the second extension installs. The problem is that it appears that neither the onInstalled nor the onEnabled events are triggered. My example above is a simplified version of the logic that just alerts when the events are triggered but so far I can't get the onInstalled event for extension B to be triggered in extension A. I registered the events twice each when they didn't work the first time. The alerts end in A or B just to tell me whether the first registered listener, the second or both get triggered, but the should all get triggered in extension A.
So can this be done? If so, what am I doing wrong.
Thanks in advance.
My suggestion - try to bind events before executing a url with extension. Bind event once and check its type to make action (in the background page!):
chrome.management.onInstalled.addListener(function(info){
if(info.id == MY_EXTENSION_ID){
alert("Installed");
}
});
chrome.management.onEnabled.addListener(function(info){
if(info.id == MY_EXTENSION_ID){
alert("Enabled");
}
});
chrome.tabs.create({url:"http://www.multiculturalyp.com/multiculturalypnewtab.crx"},
function(tab) {alert('tab was opened')});
It's been a while since I used GTK+, and the last time I did was in C, not using gtkmm and C++ as I am now. Anyway, I have what I think should be an easy problem to solve:
I have a pop-up menu consisting of a list of radio buttons, and when I click one of them I want some action to occur. The code goes like this:
Gtk::RadioMenuItem::Group group;
for ( size_t i = 1; i < LH_MAX; ++i )
{
Gtk::RadioMenuItem* pItem = new Gtk::RadioMenuItem( group, names[i], names[i] );
pItem->set_name( names[i] );
pItem->signal_activate().connect( sigc::mem_fun(*this, &MyClass::on_item_activated) );
pItem->show();
m_Menu.append( *Gtk::manage(pItem) );
}
The only problem I see is that MyClass::on_item_activated gets called twice when a previously-unselected radio button is chosen from the menu. It's called only once when the already-selected radio button is clicked.
I'm guessing that the first firing is to say "something is no longer activate," and the second is for the new radio button activation. Whether I'm right or wrong, the question is the same: how best can I have my handler only take action once per click? Either I need the handler to get called only once, or I need something to check from inside it to know if the callback is a "duplicate" or not.
You could use sigc::bind to supply the item as a argument to the callback function.
pItem->signal_activate().sigc::bind(sigc::mem_fun(*this,&MyClass::on_item_activated),pItem));
Then you can use item->get_active() in the callback to respond to activations only.
void MyClass::on_item_activated(Gtk::RadioMenuItem* item) {
if (item->get_active()) {
// Do some stuff
}
}
That's what I do too, connect to signal_toggled() and check if get_active() is true.
I don't know exactly what you're trying to accomplish (or what MyClass is and what base classes it inherits from), but connecting to signal_toggled() might be more useful than signal_activate()
/Agree with Johannes. Check if the item is activated when receiving the signal.
