try { somethingThatShouldThrowAnException(); Assert.Fail(); // raises AssertionException } catch (Exception) { // Catches the assertion exception, and the test passes } If you absolutely must catch Exception, you need to rethrow the Assert.Fail().

Therefore, use Debug.Assert() for expensive conditionals and replace the code in release builds with tests that explicitly check that the false conditional didn’t occur. Debug .Assert() is useful for when the condition specified is a long running/expensive method and the compiler is C#, Visual Basic.NET, or some compiler that pays attention to the ConditionalAttribute (the C++ CLR compiler

if code does not throws exception or throws exception of type other than T. ThrowsException(Action, String, Object[]) Tests whether the code specified by delegate action throws exact given exception of type T (and not of derived type) and throws. AssertFailedException if code does not throws exception or throws exception of type other than T. 2020-08-22 AssertThrowsException () takes a delegate and asserts that it throws the expected exception with the expected message. AssertDoesNotThrowException () takes the same delegate and asserts that it does not throw an exception. This pairing can be very useful when you want to test that an exception is thrown in one case, but not the other.

You have a better alternatives: the Assert object's ThrowsException and ThrowsExceptionAsync methods. A very extensive set of extension methods that allow you to more naturally specify the expected outcome of a TDD or BDD-style unit tests. Targets .NET Framework 4.5 and 4.7, .NET Core 2.0 and 2.1, as well as .NET Standard 1.3, 1.6, 2.0 and 2.1. IsInstanceOfType (Object, Type) Tests whether the specified object is an instance of the expected type and throws an exception if the expected type is not in the inheritance hierarchy of the object. C#. public static void IsInstanceOfType (object value, Type expectedType); … 2019-08-15 2019-10-27 Assert.Throws ( () => sut.ReadCurrentTemperature ()); } Notice in the preceding code that any InvalidOperationException thrown will pass the test.

Assert.Throws may be used with a constraint argument, which is applied to the actual exception thrown, or with the Type of exception expected. The Type format is available in both both a non-generic and (in the .NET 2.0 version) generic form. Assert.DoesNotThrow simply verifies that the delegate does not throw an exception.

To ensure that the thrown exception is correct, it can be captured and further asserts performed against it: ? 1. Exceptions thrown in an asynchronous chain return AggregateException so I want to inspect that it throws the exception which I defined as "you are not logged in".
