Property Throwing

In Explicit mode or when desired, configure getters to throw. For setters, prefer verification via Called(Count...) and callbacks.

Getter throwing

Example

imposter.Age.Getter().Throws<InvalidOperationException>();

var service = imposter.Instance();

// Read throws the configured exception
Should.Throw<InvalidOperationException>(() => service.Age);

Setter validation with throwing callbacks

Example

imposter.Age.Setter(Arg<int>.Any())
    .Callback(_ => throw new InvalidOperationException("Callback error"));

var service = imposter.Instance();

// Setter callback throws, but the attempted value is still tracked
Should.Throw<InvalidOperationException>(() => service.Age = 42);

imposter.Age.Setter(Arg<int>.Is(v => v == 42)).Called(Count.Exactly(1));
