There is also PIT which can be hooked into your build via a maven plugin or command line interface. It provides much nicer reports than the other available tools with combined mutation and line coverage. It also runs considerably faster than the source based tools for Java such as Jester, and about twice as fast … Read more
You could make internals visible to Moq by adding InternalsVisibleToAttribute in your project’s assembly.cs, like this: [assembly: InternalsVisibleTo(“DynamicProxyGenAssembly2”)] Why “DynamicProxyGenAssembly2” and not “Moq”? It’s the name of dynamic assembly created to contain dynamically generated proxy types (all of this is handled by yet another library, Castle’s DynamicProxy) which is used by Moq. So you expose … Read more
I had the same problem, the tests failed for apparently no reason. Later I found that a buggy method was causing a StackOverflowException. When I fixed my bug, the VS bug disappeared. Maybe it works most of the time because you don’t run the faulty code.
You didn’t specify a language, so I’ll try and keep this somewhat generic. It’ll be hard though, since it’s a lot easier to express concepts with actual code. Unit tests can be a bit confusing at first. Sometimes it’s not always clear how to test something, or what the purpose of a test is. I … Read more
I’ve found out that it’s because of a CoroutineDispatcher. I used to mock UI context with EmptyCoroutineContext. Switching to Unconfined has solved the problem Update 02.04.20 The name of the question suggests that there’ll be an exhaustive explanation how to unit test a suspending function. So let me explain a bit more. The main problem … Read more
I think you’ll probably want to do some integration testing to check logic that is enforced by your database structure, for example constraints, triggers, autoincrement columns, etc. You should, however, for unit testing mock out whatever framework components that your DAL relies upon as you want (in your unit tests) to test only those components … Read more
I think I got the answer to my own question. Will try to explain it here. It is not possible to validate whether the graph is plotted correctly by JS function written using D3JS. For this we may have to use Phantom.js or similar framework as mentioned by Chrisopher. I was not worried about making … Read more
It takes more code to mock a struct in Go than other OOP languages that support full late binding. This code must remain untouched since its taken from a 3rd party: type Car struct { Name string } func (c Car) Run() { fmt.Println(“Real car ” + c.Name + ” is running”) } type CarFactory … Read more
To make test run when you issue make check, you need to add them to the TESTS variable Assuming you’ve already built the executable that runs the unit tests, you just add the name of the executable to the TESTS variable like this: TESTS=my-test-executable It should then be automatically run when you make check, and … Read more
As per the solution you linked to, the way to accomplish testing two (or more) classes within a single Qt unit test project is to ensure that each class to be tested has a corresponding test class, and that you’ve created a custom int main that executes each test class. For example: class TestClassA : … Read more
