Having an argument in your it function (done in the code below) will cause Jasmine to attempt an async call. //this block signature will trigger async behavior. it(“should work”, function(done){ //… }); //this block signature will run synchronously it(“should work”, function(){ //… }); It doesn’t make a difference what the done argument is named, its … Read more
EDIT 4: Looks like this is completed in MSTest V2 June 17, 2016: https://blogs.msdn.microsoft.com/visualstudioalm/2016/06/17/taking-the-mstest-framework-forward-with-mstest-v2/ Original Answer: As of about a week ago in Visual Studio 2012 Update 1 something similar is now possible: [DataTestMethod] [DataRow(12,3,4)] [DataRow(12,2,6)] [DataRow(12,4,3)] public void DivideTest(int n, int d, int q) { Assert.AreEqual( q, n / d ); } EDIT: It … Read more
You could also Stub Consecutive Calls (#10 in 2.8.9 api). In this case, you would use multiple thenReturn calls or one thenReturn call with multiple parameters (varargs). import static org.junit.Assert.assertEquals; import static org.mockito.Mockito.mock; import static org.mockito.Mockito.when; import org.junit.Before; import org.junit.Test; public class TestClass { private Foo mockFoo; @Before public void setup() { setupFoo(); } @Test … Read more
There are different ways to use Mockito – I’ll go through them one by one. Manually Creating mocks manually with Mockito::mock works regardless of the JUnit version (or test framework for that matter). Annotation Based Using the @Mock-annotation and the corresponding call to MockitoAnnotations::initMocks to create mocks works regardless of the JUnit version (or test … Read more
Since you say you are new to unit testing and asked for mock objects in “layman’s terms”, I’ll try a layman’s example. Unit Testing Imagine unit testing for this system: cook <- waiter <- customer It’s generally easy to envision testing a low-level component like the cook: cook <- test driver The test driver simply … Read more
To run a single test method in Maven, you need to provide the command as: mvn test -Dtest=TestCircle#xyz test where TestCircle is the test class name and xyz is the test method. Wild card characters also work; both in the method name and class name. If you’re testing in a multi-module project, specify the module … Read more
Edit: Install the NuGet package System.IO.Abstractions. This package did not exist when this answer was originally accepted. The original answer is provided for historical context below: You could do it by creating an interface: interface IFileSystem { bool FileExists(string fileName); DateTime GetCreationDate(string fileName); } and creating a ‘real’ implementation which uses System.IO.File.Exists() etc. You can … Read more

pytest.raises(Exception) is what you need.

Unit testing is, roughly speaking, testing bits of your code in isolation with test code. The immediate advantages that come to mind are: Running the tests becomes automate-able and repeatable You can test at a much more granular level than point-and-click testing via a GUI Note that if your test code writes to a file, … Read more
