How to properly test web socket connection with KotlinJS - kotlin

I'm unable to test my code that uses a native WebSocket. This is the body of the test function:
val webSocket = WebSocket("ws://localhost:8888")
window.setTimeout({
assertEquals(WebSocket.OPEN, webSocket.readyState)
}, 1000)
I'm using Karma with Mocha test runner. The following code executes without any errors, but the setTimeout is actually ignored and never executed.
Mocha seems to support setTimeout-based tests with the --delay. However, when I use the flag with client: { mocha: { delay: true } } Karma configuration, the tests just freeze and fail, outputting the following cause message:
Disconnected, because no message in 60000 ms.
What is the correct way to execute tests with setTimeout? If this is tricky, is there any other way I can perform assertions on the WebSocket after it's fully connected? I don't use any Mocha-specific features yet, so I don't mind changing the framework.

Returning Promise from your #Test function should do the trick.
Something like:
#Test fun testWebSocket() = Promise<Unit> { resolve, reject ->
val webSocket = WebSocket("ws://localhost:8888")
window.setTimeout({
assertEquals(WebSocket.OPEN, webSocket.readyState)
resolve(Unit)
}, 1000)
}

If you want to test async code, you need to tell the test framework when the test is done.

Not able to use MockK in Android Espresso UI Testing

I am getting a error when trying to use MockK in UI test which was perfectly working in Unittest cases
MockK could not self-attach a jvmti agent to the current VM
Full error report
Caused by: io.mockk.proxy.MockKAgentException: MockK could not self-attach a jvmti agent to the current VM. This feature is required for inline mocking.
This error occured due to an I/O error during the creation of this agent: java.io.IOException: Unable to dlopen libmockkjvmtiagent.so: dlopen failed: library "libmockkjvmtiagent.so" not found
Potentially, the current VM does not support the jvmti API correctly

Let me know is there any other way to initialize the MockK to make use in Espresso
When tried to add
androidTestImplementation "org.mockito:mockito-inline:$mockitoVersion"
Observed this error
2 files found with path 'mockito-extensions/org.mockito.plugins.MockMaker'.
Adding a packagingOptions block may help, please refer to

Versions
mockk version = 1.12.4
Android = 32
kotlin_version = '1.6.21'
Code which causes this issue when added in android UI testcases(Espresso)
val presenter = mockk<LoginPresenter>()
val view = mockk<LoginView>()
How to perform a mock api call like this
val presenter = mockk<LoginPresenter>()
val view = mockk<LoginView>()
onView(withId(R.id.button_login)).perform(loginClick())
But i want mock api to be called
instead of loginClick() in perform() can i call some how the below execution
so that my app uses mock api's
or is there any way to make my entire testcase file use mockk data
every { presenter.onLoginButtonClicked("bc#mail.com","Abc123") } returns view.onCognitoLoginSuccess()
For me adding this solved the problem:
android {
testOptions {
packagingOptions {
jniLibs {
useLegacyPackaging = true
}
}
}
}
I found this here. Hope it helps.
Accorfing to here :
Instrumented Android tests are all failing due to issue with mockk
1.12.4
I used io.mockk:mockk-android:1.12.4 and i have same issue..
SOLUTION:
I change the version of io.mockk:mockk-android to 1.12
3 and test runed fine for me
androidTestImplementation "io.mockk:mockk-android:1.12.3"

Integrationtest IHost TestServer won't shutdown

I wrote some integration tests for an aspnetcore 3.1 application using xunit.
Tests show successful, but process is still running. After some time I get:
The process dotnet:1234 has finished running tests assigned to it, but is still running. Possible reasons are incorrect asynchronous code or lengthy test resource disposal [...]
This behavior does even show with boilerplate code like:
[Fact]
public async Task TestServer()
{
var hostBuilder = new HostBuilder()
.ConfigureWebHost(webHost =>
{
// Add TestServer
webHost.UseTestServer();
webHost.Configure(app => app.Run(async ctx =>
await ctx.Response.WriteAsync("Hello World!")));
});
// Build and start the IHost
var host = await hostBuilder.StartAsync();
}
Same if I add await host.StopAsync()...
I am on an Ubuntu 18.04 machine.
Try to dispose the host at the end of the test. Most likely, the error is caused just because you don't dispose disposable resource.
I would recommend you to use WebApplicationFactory for testing instead of HostBuilder. You may find more in the docs
I had the same problem. Since i was working with NUnit the suggested change was not an option (it is based on xunit). So i was digging into it and the root cause of it was quite simple:
I created a long running task in the Startup.cs which was doing some monitoring throughout all the hosting's lifetime. So i had to stop this task, and then also the instance of the TestHost was disposed properly.

Can you test SetUp success/failure in Google Test?

Is there a way to check that SetUp code has actually worked properly in GTest fixtures, so that the whole fixture or test-application can be marked as failed rather than get weird test results and/or have to explicitly check this in each test?
If you put your fixture setup code into a SetUp method, and it fails and issues a fatal failure (ASSERT_XXX or FAIL macros), Google Test will not run your test body. So all you have to write is
class MyTestCase : public testing::Test {
protected:
bool InitMyTestData() { ... }
virtual void SetUp() {
ASSERT_TRUE(InitMyTestData());
}
};
TEST_F(MyTestCase, Foo) { ... }
Then MyTestCase.Foo will not execute if InitMyTestData() returns false. If you already have nonfatal assertions in your setup code (i.e., EXPECT_XXX or ADD_FAILURE), you can generate a fatal assertion from them by writing ASSERT_FALSE(HasFailure()); You can find more info on failure detection in the Google Test Advanced Guide wiki page.

IBM Worklight 5.0.6.1 - onFailure and onSuccess execution at Client.connect() and invokeProcedure() NOT exclusive when timeout?

We are seeing a surprising scenario when we are on a slow network connection and our calls to the WL Server time out.
This happens at WL.Client.connect as well as on invokeProcedure:
we execute the call with a timeout of 10 seconds
the network connection is slow so the call times out
the defined onFailure procedure associated to that call is executed
the WL Server responds with a valid response after the timeout
the onSuccess procedure associated to that call is executed
Is this the designed and intended behavior of the WL Client Framework? Is this specified in the InfoCenter documentation or somewhere?
All developers in our team expected these two procedures to be exclusive and our code was implemented based on this assumption. We are now investigating options on how to match a timed-out/failed response to a success response to make sure we achieve an exclusive execution of onFailure or onSuccess code/logic in our app.
Note: we did not test that with connectOnStartup=true and since the initOptions does not provide an onSuccess procedure (since WL handles that internally) it might be even harder to implement an exclusive execution in this case.
That seems like expected behavior, but don't quote me on that.
You can get the behavior you want (only call the failure callback when it fails, and only call the success callback when it succeeds) using jQuery.Deferreds. There are ways of creating these deferred objects with dojo and other libraries. But, I just tested with jQuery's implementation, which is shipped with every version of IBM Worklight.
$(function () {
var WL = {};
WL.Client = {};
WL.Client.invokeProcedureMock = function (options) {
options.onFailure('failure');
options.onSuccess('success');
};
var dfd = $.Deferred();
var options = {
onSuccess: dfd.resolve,
onFailure: dfd.reject
};
WL.Client.invokeProcedureMock(options);
dfd
.done(function (msg) {
// handle invokeProcedure success
console.log(msg);
})
.fail(function (msg) {
//handle invokeProcedure failure
console.log(msg);
});
});
I put the code above in a JSFiddle, notice that even if I call the onSuccess callback, it won't have any effect because I already called the failure callback (which rejected the deferred). You would add your application logic inside the .done or .fail blocks.
This is just a suggestion, there are likely many ways to approach your issue.

Worklight Direct Update and run offline

I want to achieve such a functionality.
That is:
1) in case of connecting to worklight server successfully, Direct Update is available.
2) in case of failing to connect to worklight server, the app can run offline.
Below is my configuration in "initOptions.js".
// # Should application automatically attempt to connect to Worklight Server on application start up
// # The default value is true, we are overriding it to false here.
connectOnStartup : true,
// # The callback function to invoke in case application fails to connect to Worklight Server
onConnectionFailure: function (){
alert("onConnectionFailure");
doDojoReady();
},
// # Worklight server connection timeout
timeout: 10 * 1000,
// # How often heartbeat request will be sent to Worklight Server
heartBeatIntervalInSecs: 20 * 60,
// # Should application produce logs
// # Default value is true
//enableLogger: false,
// # The options of busy indicator used during application start up
busyOptions: {text: "Loading..."
But it doesn't work.
Any idea?
Direct Update happens only when a connection to the server is available. From the way you phrased your question, your problem is that when the app cannot connect to the server it doesn't work "offline". So your question has got nothing to do with Direct Update (if it does, re-phrase your question appropriately).
What you should do, is read the training material for working offline in Worklight.
You are not specifying what "doesn't work". Do you get the alert you've placed in onConnectionFailure? How does your doDojoReady function look like?
I too am using Dojo in Worklight.
My practice is have worklight configured not to connect on startup
var wlInitOptions = {
connectOnStartup : false
in my wl init I then initialise my dojo app,
function wlCommonInit(){
loadDojoLayers();
};
requiring whatever layers I'm using, and then do the actual dojo parsing
require([ "dojo/parser",
"myApp/appController",
"dojo/domReady!"
],
function(parser, appController) {
parser.parse().then (function(){
appController.init();
});
});
Finally, now WL, Dojo, and myApp are all ready I attempt the WL connection, calling this method from my appController.init()
connectWLServer: function() {
// possibly WL.Client.login(realm) here
var options = {
onSuccess: lang.hitch(this, "connectedWLServer"),
onFailure: lang.hitch(this, "connectWLServerFailed"),
};
WL.Client.connect(options);
}
Any Direct Update activities happen at this point. Note that the app as whole keeps going whether or not the connection works, but clearly we can run appropriate code in success and fail cases. Depending upon exactly what authentication is needed an explicit login call may be needed - adapter-based authentication can't happen automatically from inside the connect().
