Scalamock expect eventually - asynchronous

I'm using scalamock to write a test. The problem is that action is asynchronous.
I have the following pseudo code
val resultCollectorMock = mock[ResultCollector]
(resultCollectorMock.collectResult _).expect(someResult)
val serviceUnderTest = new ServiceUnderTest(resultColletorMock)
serviceUnderTest.runAsyncJob(someParams)
This fails because the result is computed asynchronously, at time when the test ends, it's still not ready, so collectResult wasn't called, yet.
What I want to have is expectEventually(value)(patienceConfig) that is able to wait for some time for the method to be called.
I tried to use a sutb and verify instead, I wrapped it in eventually from scalatest but to no avail. For whatever reason verify seems to break the test at first evaluation.

you should use AsyncMockFactory with an appropriate test suite and Futures as described in the docs at https://scalamock.org/user-guide/integration/

if-else conditions based on expect statement results

I'm working towards testrail integrations, i want to update testrail after each test pass/fail. Lets day if i've a test like below
it('rightpanel should exist', () => {
//some logic or preparatory work
expect(rightpanel.isLoaded()).to.be.true;
// here i want to know whether above expect statement failed or passed.
// based on it, i want to update test rail by making a webservice call
});
we are using WDIO, is there a better way to integrate to testrail? No one replies on their community forum so, i'm asking here.
With mocha you can use a repoter to manage the results of your tests.
The default reporter is Spec, but if you use json-stream you can attach another process to this stream to send test reports to testrail while executing.
Otherwise, if you don't need to send them in real time, you can use the json reporter and parse them in a single call.
You can also check on github some existing reporter that connects directly to testrail:

How to mock an inlined InitiatingFlow return value during another flow

I have SomeBigFlow that calls multiple subflows inside it i.e ValidateFlowA, ValidateFlowB. Assuming it is mandatory for A and B to be initiating flows not functions.
How do I mock a return value for ValidateFlowA when I run the SomeBigFlow in Junit?
I've seen some references to using registerAnswer to mock flows' return value here. I am also curious why this function is only available for InternalMockNetwork.MockNode but not MockNetwork.StartedMockNode which is typically used during junit testing)
I thought I could replicate it by having node[1].registerAnswer(ValidateFlowA.class, 20). But when I ran node[1].startFlow(SomeBigFlow).resultFuture.getOrThrow(), the ValidateFlowA is still using its default call implementation instead of returning the mocked 20 integer value. Maybe I'm using it wrong.
Any pointers on how to make this work or is there a solution to achieve mocking inlined subflows returned values? The only other way I can think of is have a rule of thumb that whenever calling an inlined subflow, put them in an open fun that can be overridden during mocknetwork testing - this makes inlined subflow tedious, hoping for a neater way.
For now, you'd have to use a similar approach to the one outlined here: Corda with mockito_kotlin for unit test.
In summary:
Make the FlowLogic class you are testing open, and move the call to the subflow into an open method
For testing, create a subclass of the open FlowLogic class where you override the open method to return a dummy result
Use this subclass in testing

How can I run a task inside a meteor method without waiting for it to complete?

I have several function calls in a row that run and wait to return, then the next one runs. After these are run I have one function I want to run, but then I don't want to wait for it to be done before I run my return.
Here is an example of what I mean.
get_card, create_order, create_association and debit_order all need to wait for the previous function to complete before they can run. When I get to Queue.start_account_creation_task I want it to start running, but then let the return on the line below run right away too.
Meteor.methods({
singleDonation: function (data) {
logger.info("Started singleDonation");
//Get the card data from balanced and store it
var card = Utils.get_card(customerData._id, data.paymentInformation.href);
//Create a new order
var orders = Utils.create_order(data._id, customerData.href);
//Associate the card with the balanced customer
var associate = Utils.create_association(customerData._id, card.href, customerData.href);
//Debit the order
var debitOrder = Utils.debit_order(data.paymentInformation.total_amount, data._id, customerData._id, orders.href, card.href);
Queue.start_account_creation_task(customerData._id, data._id, debitOrder._id);
return {c: customerData._id, don: data._id, deb: debitOrder._id};
}
});
Sounds like you need parallel and serial control for tasks. The (as in, 400,000 downloads a day) Node.js module for that is called async, and a Meteor wrapper for it is peerlibrary:async.
Sooner or later you'll need a dedicated background task management package. If async is insufficient, have a look at my evaluation of packages to control background tasks in Meteor.
The thing that seemed to work the best for what I was trying to do was to just use a Meteor.setTimeout({}). It might seem like an odd choice, but it does everything I needed, including setting the Meteor Environment so that I didn't have to do any BindEnrironment call. It also breaks out of the current thread of calls, which means it then returns the result to the client and a second later finishes the rest of the calls (which are to external APIs that I didn't need my users sitting there waiting for).

custom validator against remote object

I have a need to validate a field against our database to verify unique-ness. The problem I seem to be having is that the validators doValidation() exits before we've heard back from database.
How can I have the validator wait to return its payload until after we've heard from the DB?
Or perhaps a better question might be (since I think the first question is impossible), how can I set this up differently, so that I don't need to wait, or so that the wait doesn't cause the validation to automaticallly return valid?
If you're using a remote object, you can specify the method call inside your remote declaration and assign a function to the result call. The result call only runs once the remote server returns something, so it won't be run before your validation.
Do your validation call in said result function call (which you will have to create) and you should be good. Your code should go something like this:
<s:RemoteObject id="employeeService"
destination="ColdFusion"
source="f4iaw100.remoteData.employeeData"
endpoint="http://adobetes.com/flex2gateway/"
result="employeeService_resultHandler(event)"/>
**<s:method name="dataCheckCall" result="dataCheckResult(event)"/>**
<s:RemoteObject />
And in your script:
function protected dataCheckResult(event:ResultEvent):void {
**doValidate();**
}
Edit: As soon as you call "dataCheckCall" the method will start running. If, for whatever reason, you want to call this WITHIN your validator, you can do so, and then dataCheckResult will run whenever it returns with it's payload (pretend doValidate is called elsewhere). I've left a message below as well.
You are trying to fit an asynchronous process (fetching data from a DB) into a synchronous process (checking all the validators in turn).
This won't work...
You'll need to either roll your own validator framework, or use a different method of determining the legality of your controls.
P.S. The MX validators are rubbish anyway!
What I've managed to do, seems to work, mostly. I don't like it, but it at least performs the validation against the remote source.
What I've done, then, is to use an 'keyUp' event handler to spin off the database lookup portion. In the meanwhile, I set up a string variable to act as some kind of a Flag, which'll be marked as 'processing'. When the response event fires, I'll examine its contents, and either clear the flag, or set it to some kind of other error.
Then, I have created a new 'EmptyStringValidator' will check the contents of this flag, and do its job accordingly.
Its indirect, but, so far, seems to work.

Detect when ALL HTML page rendering has taken place

I am working with a pretty complicated .aspx page that is full of controls (Telerik, Ajax, etc.) that all expand, collapse, show, hide, etc. when the page is loaded. Since this rendering happens on the client-side and can take different lengths of time based on the users machine specs, is there a way to detect when all (or some) rendering has taken place (jQuery?) so I can then act on specific elements, knowing they are fully rendered?
JavaScript is single threaded. The time passed to setTimeout is a minimum, but not a maximum, so if you pass something like 10(ms), you essentially are saying "execute this code after all the currently running code is finished."
So, if all the controls use $(document).ready() to do their thing, all you need is:
$(document).ready(function() {
setTimeout(function() {
doStuff();
},10);
});
doStuff will be called after all the functions passed to $(document).ready have run. However, this isn't foolproof. If the controls have their own way of detecting whether the document has loaded, or do their own setTimeout(), you're in trouble. The problem is that JavaScript does not guarantee the execution order of setTimeouts. Sometimes your code may run last, other times it may run before the setTimeouts used for the animation.
One last idea: if all the animation is done using jQuery, then the effects run in a single queue. In doStuff you could add an animation of some sort with a callback and be reasonably certain that the callback would run last.
Whenever I had to wait for multiple things to be ready before proceeding, I would create an array with true/false values. Every mandatory part of the page got an event which, when it is called, updates the specific entry in the array to true. Also, it called a general function which returned true if all values in an array was true, otherwise false.
If that function finally returned true, I would proceed with the execution. It is especially useful if you have to wait for an AJAX call to end but don't want to use async = true. It also is useful if you want to start loading multiple things at once instead of one after another, since they all report ready-state to the same array.
It does however use global variables so you might need to do some optimizations. You might not want to do this approach either if you have a grudge against global variables.
You should place your code inside the jQuery $(document).ready() function. This will ensure that all elements are loaded before the code runs.
http://docs.jquery.com/Tutorials:Introducing_$(document).ready()
I think the doc you need is:
http://docs.jquery.com/Events/load
"I can then act on specific elements, knowing they are fully rendered?"
You can use the load method (linked above) to attach to any element. So if you had a div with an id of "lastElement", you could write
$('div#lastElement).load(runThisFunction);
