unit-testing

问题 Using this manual to test Coroutines using runBlockingTest . I encountered some issues. If the coroutine created by launch or async calls delay then the runBlockingTest will not auto-progress time right away. This allows tests to observe the interaction of multiple coroutines with different delays. @Test fun testFooWithLaunchAndDelay() = runBlockingTest { foo() // the coroutine launched by foo has not completed here, it is suspended waiting for delay(1_000) advanceTimeBy(1_000) // progress

问题 I am in the middle of re-writing my translator and I am being much more disciplined about tests this time, since this version is likely to live for more than a few weeks. Because you can run a visitor starting at any node, you can almost write beautiful small tests like this ... expect(parse("some test code", "startGrammarRule")).toEqual(new ASTForGrammarRule()) and then write one ( or a few of these ) for each visitor function EXCEPT that the rule you are invoking is a sub rule, and so does

问题 I am creating a web app unsing Angular 4 and RxJs. In one part of my code I am creating a websocket using: Observable.websocket(url); function. Here is my code: /** * Tries to open a websocket connection to a given URL. * @param url * @param subscription Previous subscription to this socket (it may be necessary to close it before proceeding) * @returns an object containing the subscription and the websocket subject. */ private openConnection(url: string, subscription: Subscription): { socket$

问题 I am trying to write a test case test_is_user_present() which calls another function execute_redshift_sql() from redshift_util.py script I set the expected return value from the function execute_redshift_sql() to 1 . But I never get this value returned from result after the function is called ! I also printed some values for debugging purpose You can take a look at test case below from mock import patch, Mock, MagicMock from cia_admin_operations.redshift_util import execute_redshift_sql

问题 I am new to writing Unit tests. I saw few examples of jUnit , but they all were for functions returning a value. I have to write unit test for following method. Also we are using objects and methods in this method not belonging to this class like ConfigParser and ParseConfig. How do i go about writing Unit tests for such menthods? @RequestMapping(value = "/generate-json" , consumes = MediaType.APPLICATION_JSON_VALUE, method = RequestMethod.POST) @PageType(pageType = "PlaceHolderPageType")

问题 This is my code return Observable.defer(() -> mApi.verifyReceipt(username, password)) .subscribeOn(Schedulers.io()) .doOnNext(this::errorCheck) .repeatWhen(observable -> observable.delay(1, TimeUnit.SECONDS)) .takeUntil(Response::body) .filter(Response::body) .map(Response::body); It keeps polling and receives a "false" boolean response and stops polling when "true" is received. I've made a test case for the onNext() case like: @Test public void testVerifyReceiptSuccessTrueResponse() {

问题 I'm trying to add some unit tests to a Visual Studio Code extension I'm developing. I've followed the recipe for setting up extension testing described here: https://code.visualstudio.com/api/working-with-extensions/testing-extension This recipe, however, doesn't show anything useful being done to actually test an extension, just the skeleton for getting set up to do so. For the testing I want to do, one of the first things I want to do is open a sample project . And that's where I get stuck.

问题 I am making a simple snackbar for which code as follows, app.component.ts: ngOnInit(){ this.dataService.valueChanges.pipe( filter((data) =>data=== true), switchMap(() => { const snackBarRef = this.matSnackBar.open( 'A new value updated', 'OK', { duration: 3000 } ); return snackBarRef.onAction(); }) ) .subscribe(() => { this.window.location.reload(); }); } app.component.spec.ts (Including mock data for service) describe('AppComponent', () => { let component: AppComponent; let fixture:

问题 By default, the output in the pipeline is hidden,But sometimes I really want to know the output at that time. Of course, I knew I could add additional commands, such as write-host or out-default. But does Pester itself have a mechanism to make the output display properly? I checked the help document and didn't find the relevant content, so I came here for help. 回答1: It is possible to write a custom Should wrapper (proxy) using this technique. The wrapper can write the pipeline objects to the

问题 I'm using Django 1.10 and Celery 4.1 I have a shared_task which sends an email to the user. # myapp/tasks.py @shared_task def notify_user(user_id): # TODO: send email and do other stuff here user = get_object_or_404(User, pk=user_id) send_mail( 'Subject', 'Body', 'from@example.com', [user.email], ) I have another file which contains a function that calls puts that tasks into the queue. # myapp/utils.py # ... def update_queue(self): # increment no_of_used_referrals by 1 if no_of_used_referrals
