Getting Values From Swapped Instances

Hi,

I am not sure I understood what you meant.

If you want to verify that Statement was set to a specific value you can do it using the Verify methods. By the way, Isolator True Properties feature makes the test pass without setting "CallOriginal" on the properties.

For example:

var fake = Isolate.Fake.Instance<A>();
Isolate.SwapNextInstance<A>().With(fake);

var a = new A();
a.Statement = "A";

Isolate.Verify.WasCalledWithExactArguments(() => { fake.Statement = "A"; });
Assert.AreEqual("A", a.Statement);

If you want to perform an action when the value is being set you can do it using the "DoInstead" functinallity.

For example:

var fake = Isolate.Fake.Instance<A>();
Isolate.SwapNextInstance<A>().With(fake);

string propertValue = string.Empty;

Isolate.WhenCalled(() => fake.Statement)
    .DoInstead(context => propertValue);

Isolate.WhenCalled(() => fake.Statement = "")
    .DoInstead(context =>
    {
        propertValue = (string) context.Parameters[0];
        return propertValue;
    });



var a = new A();
a.Statement = "A";

Isolate.Verify.WasCalledWithExactArguments(() => { fake.Statement = "A"; });
Assert.AreEqual("A", a.Statement);

Please let me know if it helps.
