问题 public class A{ private final B b; public void meth() { //Some code Integer a = b.some_method(a,fun(b)); //Some code } private fun(int b) { return b; } } when(b.some_method(anyInt(),anyInt())).thenReturn(100) How to mock the externally dependency when writing unit tests for class A. When i mock dependency in the above way, the value of "a" is not getting assigned to 100 as expected. 回答1: Actually the answer of Jakub is correct. Maybe you need an example to understand how to do it. Check the

问题 I am trying to test an async function that uses data returned by another async function. Here is the code to explain my problem: StudentInfo.js export async function getData() { //studentData imported from another file return new Promise(resolve => { setTimeout(() => { resolve(studentData); }, 5000); }); } export async function filterStudents() { const studentData = await StudentInfo.getData(); //computations return filteredData; //object } StudentInfo.test.js import * as studentInfo from

问题 I'm trying to build my first unit tests and have a class that increments and decrements an instance counter in it's constructor and destructor respectively. I have a test to make sure this works but it fails, it seems that other instances of the class from my other tests aren't having their destructor called when they go out of scope. public class Customer { public Customer() { ++InstanceCount; } public Customer(int customerId) { CustomerId = customerId; ++InstanceCount; } ~Customer() { -

问题 I’m using SpecFlow to write a set of tests, and I’d like to run each test multiple times, with different input data. I could do this with scenario outlines, but I want to run every scenario in the feature file with the same test cases. I know I can use the Background to share the setup for one case, but I’m looking for something like a cross between Background and Scenario Outline, where I can supply a table of data to the Background and run the entire feature file once per row. In NUnit, I’d
