testing

问题 I am using @angular-builders/jest in order to replace karma by jest when testing angular projects. There are 2 libraries that I like to get extra matchers for jest: jest-extended and @testing-library/jest-dom . I cannot find a way to import automatically the matchers so that I don't have to import them in each spec file. minimal example to reproduce the problem with jest-extended First, create an angular project and install jest dependencies ng new --defaults my-project cd my-project yarn add

问题 Suppose I have a test expressed as a simple script with assert -statements (see background for why), e.g import foo assert foo(3) == 4 How would I include this script in my pytest test suite -- in a nice way? I have tried two working but less-than-nice approaches: One approach is to name the script like a test, but this makes the whole pytest discovery fail when the test fails. My current approach is to import the script from within a test function: def test_notebooks(): notebook_folder =

问题 PROBLEM I have a fairly large Hydro-Pneumatic system model composed of roughly 20-25 different subsystems. Each of the subsystem is then composed of digital logic, edge delay blocks, and gateway to external output ports (real-world outputs). Additionally some of the small building blocks are legacy C code imported as S-functions in order to maximise cost-benefit ratio. Each of the subsytem model has been designed in SIMULINK with the use of basic blockset i.e. no add-on commercial blocksets

问题 I am trying to use Kiwi TCMS RPC API (project page) with the newest version installed (3.49) and it fails miserably as below even though I follow the API documentation. I wonder if there is someone that could point me in the right direction. File "api_test.py", line 18, in <module> print(testplan.author) File "/usr/local/lib/python3.4/dist-packages/tcms_api/base.py", line 63, in getter self._fetch() File "/usr/local/lib/python3.4/dist-packages/tcms_api/mutable.py", line 273, in _fetch inject

问题 I am trying to test to write to a Parcel in Android test but it doesnt't work. s==null! What is wrong? public class scraptest extends AndroidTestCase { public void test() { Parcel parcel=Parcel.obtain(); parcel.writeString("sdfsdf"); String s=parcel.readString(); } } 回答1: One must reset the Parcel's data position with: parcel.setDataPosition(0); 来源： https://stackoverflow.com/questions/22832403/parcel-write-read-doesnt-work-in-androidtestcase-why

问题 I'm having a bit of trouble showing a winform during a unit test. I'm using this as a user validated testing procedure to show the user 2 different image segments captured during Selenium UI testing and the diff between them and allowing the user to pass or fail the test based on whether or not the images are too different. I've created the form with 2 PictureBox elements and added methods to the form to allow the form to take in the images I require and load them into the PictureBox and then

问题 After ng test Expected output: i get pass/fail on x amount of tests. Actual ouput: ERROR in src/app/todo-data.service.spec.ts(19,45): error TS2345: Argument of type 'Todo[]' is not assignable to parameter of type 'Expected<Observable<Todo[]>>'. Type 'Todo[]' is not assignable to type 'ObjectContaining<Observable<Todo[]>>'. Property 'jasmineMatches' is missing in type 'Todo[]'. In my todo class i don't have a jasminematches property, but this might not be the root problem. todo.ts: export

问题 I have the given testing code: describe 'A new user', js: true do before do @new_user = Fabricate.build(:user) end it 'should sign up' do #login code visit '/' click_link 'Login' fill_in 'user[email]', :with => @new_user.email fill_in 'user[password]', :with => @new_user.password click_button 'Login now' #login code end page.should have_content("Hello #{@new_user.first_name}!") current_path.should == dashboard_path end it 'should receive a confirmation mail' do #same login code again visit '/

问题 I'm trying to test an endpoint from my express application using Jest. I'm migrating from Mocha to try out Jest to improve the speed. However, my Jest test does not close? I'm at a loss... process.env.NODE_ENV = 'test'; const app = require('../../../index'); const request = require('supertest')(app); it('should serve the apple-app-site-association file /assetlinks.json GET', async () => { const response = await request.get('/apple-app-site-association') expect(response.statusCode).toBe(200);

问题 I'm using mirage to mock some data and I'd like to mock an <img> with the appropriate file. The problem is that I will have to place the image in /public/assets and the images placed there will be deployed later on as well. Is there a way to avoid this? I couldn't find a recommendation in the ember cli website (https://ember-cli.com/user-guide/#asset-compilation) I found one addon that could do this (ember-test-assets), but I'd like to avoid installing extra addons as much as possible. Thanks
