testing

问题 I am testing a function in which both def foo(): with open('input.dat', 'r') as f: .... with open('output.dat', 'w') as f: .... are used. But I only want to mock the write part. Is it possible to do that? Or some other strategy should be used for testing such a function? with patch('__builtin__.open') as m: foo() would fail to read the data. Thanks in advance. 回答1: I found the following solution: from mock import patch, mock_open with open('ref.dat') as f: ref_output = f.read() with open(

问题 Using a builder to generate a smaller docker image, what would be a good way to run npm run test ? I seems like running it in the Dockerfile after the build would make sense but maybe I'm missing something Dockerfile # Global args to persist through build stages ARG docker_build_user ARG docker_build_time ARG docker_build_head ARG docker_build_head_short ARG docker_build_submodules_head FROM node:8.9.4-alpine as builder WORKDIR /app COPY . . RUN apk add --no-cache bash RUN apk add --no-cache

问题 I was going through an online course on test driven development and came across the concept of test doubles. As per the definition of test double in the course : Test Doubles : Test doubles are objects that are used in unit tests as replacement to the real production system collaborators. I got an idea what test doubles mean. But then it was mentioned there are various types of test doubles. The ones mentioned in the course were : Dummy : Objects that can be passed around as necessary but do

问题 How can I test if an input field is infocus with protractor? I'm doing this: it('should focus email field', function(){ expect(element(by.model('login.email')).getAttribute('id')).toEqual(browser.driver.switchTo().activeElement().getAttribute('id')); }); This seems to work with chrome, but this test fails with firefox. Any ideas? This is the failure message: [firefox #1] 2) Login page should focus email field [firefox #1] Message: [firefox #1] Expected 'login' to equal ''. [firefox #1]

问题 We can display the actual thread by: ${__threadNum} Is there something similar for the actual loop count? 回答1: You can use ${__jm__Thread Group__idx} to get current loop iteration ${__jm__Thread Group__idx} Notice this is part of a general enhancement in JMeter 5 for exposing the loop count While Controller now exports a variable containing its current index named __jm__<Name of your element>__idx . So for example, if your While Controller is named WC , then you can access the looping index

问题 Here is a TestFixture class that I have: namespace TestApplication.Tests { [TestFixture] [Property("type","smoke")] public class LoginFixture { [Test] [Property("role","user")] public void can_login_with_valid_credentials() { Console.WriteLine("Test") } } } As you can see I set Nunit "Property" Attribute for Test and TestFixture levels. It is easy to get "Property" value from Test level: var test = TestContext.CurrentContext.Test.Properties["role"] But don't understand how to get "Property"
