Yes, with a simple refactoring. Create a zSomeFunc variable of function type, initialized with z.SomeFunc, and have your package call that instead of z.SomeFunc(): var zSomeFunc = z.SomeFunc func abc() { // … v := zSomeFunc() // … } In tests you may assign another function to zSomeFunc, one that is defined in tests, and … Read more

Test-driven developers should feel right at home in functional languages like F#: small functions that give deterministically repeatable results lend themselves perfectly to unit tests. There are also capabilities in the F# language that facilitate writing tests. Take, for example, Object Expressions. You can very easily write fakes for functions that take as their input … Read more
Martin Fowler wrote an excellent article on this subject. From that article: Meszaros uses the term Test Double as the generic term for any kind of pretend object used in place of a real object for testing purposes. The name comes from the notion of a Stunt Double in movies. (One of his aims was … Read more
Yay! Now it’s testable; I can feed in test doubles (mocks) to the DoIt method. But at what cost? I’ve now had to define 3 new interfaces just to make this testable. And what, exactly, am I testing? I’m testing that my DoIt function properly interacts with its dependencies. It doesn’t test that the zip … Read more
I hope you’ve installed – npm install –save-dev @types/jasmine Then put following import at the top of the hero.spec.ts file – import ‘jasmine’; It should solve the problem.
Use this: mocha server-test Or if you have subdirectories use this: mocha “server-test/**/*.js” Note the use of double quotes. If you omit them you may not be able to run tests in subdirectories.
How to mock specific methods but not all of them in Rust? As you have already learned, you cannot replace methods on a type. The only thing you can do is move the methods to a trait and then provide production and test-specific implementations of that trait. How you structure the trait determines the granularity … Read more
The examples you provide do not use Dependency Injection. Instead, Bar should use Constructor Injection to get a Foo instance, but there’s no point in injecting a concrete class. Instead, you should extract an interface from Foo (let’s call it IFoo) and inject that into Bar: public class Bar { private IFoo f; public Bar(IFoo … Read more
Resharper shadow copies assemblies for testing by default. If you turn off shadow-copy, it will run in the bin folder and the test should pass. Here are some instructions on turning it off.
