How to convert csv into mock when csv file is specified as argument in unit test of Django command There is a django command that gives the path of the csv file as an argument as follows. class Command(NoticeCommand): def add_arguments(self, parser): parser.add_argument( '--file', dest="file", type=str, required=True ) def handle(self, *args, **options): with open(options['file'], 'r') as f: reader = csv.reader(f) next(reader) for row in reader: ... I am thinking to make this csv file mock when doing unit test. However, I do not know which part and how to make mock. Also, the argument is required = True . How can I call UnitTest when csv is mocked? required = True from mock import patch from django.core.management import call_command class ImportCsvTest(TestCase): @patch("common.management.commands.import_csv.????") def test_import_csv(self...

how to test that a method throws an exception junit5 [duplicate] This question already has an answer here: I have a DocumentTypeDetector class that has a detectForRequest() method. I'm doing the corresponding tests, but I have not been able to verify that a customized exception is thrown, I'm using JUNIT 5. DocumentTypeDetector detectForRequest() I have reviewed here, but the answers have not helped me, this is the code I have written following an example: @Test public void tryThrowExceptionForInvalidRequest() throws Exception{ InvalidInputRequestType exceptionThrown = Assertions.assertThrows( InvalidInputRequestType.class, () -> { throw new InvalidInputRequestType("La petición debe estar en un formato valido JSON o XML"); } ); assertEquals("La petición debe estar en un formato valido JSON o XML", exceptionThrown.getMessage()); } But this does not tell me anything about my test I need to ve...

Throw exception in test method using MSTest I'm using MSTest to write test cases for my application. I have a method where files are moved from one directory to another directory. Now when I run code coverage, it shows that the catch block is not covered in code coverage. This is my code as below. class Class1 { public virtual bool MoveFiles( string fileName) { bool retVal = false; try { string sourcePath = "PathSource"; string destinationPath = "DestPath"; if (Directory.Exists(sourcePath) && Directory.Exists(destinationPath)) { string finalPath = sourcePath + "\" + fileName ; if (Directory.Exists(finalPath)) { File.Move(finalPath, destinationPath); retVal = true; } } } ...

test timers in react, sinon or jest I have a funtion checkIdleTime , being set to be called periodically. checkIdleTime componentDidMount() { var idleCheck = setInterval(this.checkIdleTime.bind(this), authTimeoutSeconds * 1000); this.setState({idleCheck: idleCheck}); document.onkeypress = this.setActive; } I want to use the fake timer for test, but can't figure out how, tried sinon and jest . sinon jest beforeEach(() => { checkIdleTime = jest.spyOn(PureMain.prototype, 'checkIdleTime'); wrapper = shallow( <PureMain/> ); jest.useFakeTimers(); //clock = sinon.useFakeTimers(); }); it('should check the idle time after [authTimeoutSeconds] seconds of inactivity', () => { wrapper.instance().componentDidMount(); var idleCheck_timeout = wrapper.instance().state.idleCheck; expect(idleCheck_timeout).not.toEqual(null); expect(idleCheck_timeout._idleTimeout).toBe(authTimeoutSeconds * 1000); jest.runAllTi...

Testing with Mocha and Chai consuming values from previous tests I have some tests created with mocha and chai using TypeScript , they actually work as expected. Each function returns a Promise which runs a test . mocha chai TypeScript Promise test My question is if is there anyway to consume on each test the value returned by a previous test without using the nesting you see below. test test My concern is that if I have more test the nesting code could be very annoying going to the right test import * as request from 'supertest'; import app from '../src/app'; import { Promise } from 'bluebird'; import * as dateformat from 'dateformat'; import Commons from '../../utils/commons'; import { expect } from 'chai'; ... // all the functions used below are defined over here ... registerNonExistingUser(email, pass, role).then( (jwtToken: string) => { authenticateUserCorrectJwt(jwtToken).then( (user) => { ...

Running multiple testbenches for VHDL designs Whenever I create a VHDL design I tend to have many modules. Each of these modules are then connected to one main file and so everything is synthesised. But I want to write seperate test benches for each of these modules and one for the global process. It would be nice if I could do something to link all of these testbenches together and make them run in succession, to test my entire design in one run. How could I do this? I like to use GHDL and asserts. Is it possible to create one super-testbench? Or would a shell script which iterates over them be better? Good strategy. There are unit testing tools for VHDL too ... one called VUnit for example : github.com/LarsAsplund/vunit – Brian Drummond Jan 23 '16 at 23:20 @Paebbels, you are right. F...

angular 2 test URL differentiates from web API URL I have an angular-cli project, embedded in visual studio 2017. By running vs project the angular project is being served and everything works. then when I want to test the angular project with ng test , it will be served on http://localhost:9876 but API is unavailable on this URL. ng test http://localhost:9876 Web API URL is http://localhost:42339/ . and test fails because request goes to http://localhost:9876 . I changed the service URLs http://localhost:42339/ http://localhost:9876 getTagData(): Observable<any> { return this.adminBaseService.get(`http://localhost:42339/api/admin/Tags/GetTags`); } but it makes calls to http://localhost:9876 http://localhost:9876 Any help? I think you should define route in angular project. this url is for backend. you need define a component and service for http. and use this service in component. then define a route for the component. –...
