Property Verification

Setter verification

Example

service.Age = 33;
service.Age = 34;

imposter.Age.Setter(Arg<int>.Any()).Called(Count.AtLeast(2));
imposter.Age.Setter(Arg<int>.Is(34)).Called(Count.Once());

Getter verification

Example

var _ = service.Age;
imposter.Age.Getter().Called(Count.Once());

Failures

When verification fails, VerificationFailedException is thrown with the message:

Invocation was expected to be performed {expectedCount} but instead was performed {actualCount} times.

Examples:

Example

// Setter expected once for value 34, but no matching write occurred
imposter.Age.Setter(Arg<int>.Is(34)).Called(Count.Once());
// throws: "Invocation was expected to be performed exactly 1 time(s) but instead was performed 0 times."

// Getter expected at least 2 reads, but only 1
var _ = service.Age;
imposter.Age.Getter().Called(Count.AtLeast(2));
// throws: "Invocation was expected to be performed at least 2 time(s) but instead was performed 1 times."

Tips - Use Arg<T> matchers to target specific values. - Pair verifications with callbacks when you need to capture payloads.
