❔ ✅ Verifying the purpose of Moq usage

mockDatabase.Setup(db => db.GetUserName(It.IsAny<int>()))
    .Returns((int userId) => "User" + userId);

mockDatabase.Setup(db => db.GetUserName(It.IsAny<int>()))
    .Returns((int userId) => "User" + userId);

mockDatabase.Setup(db => db.GetUserName(It.IsAny<int>()))
    .Returns((int userId) => "User" + userId);

mockDatabase.Setup(db => db.GetUserName(It.IsAny<int>()))
    .Returns((int userId) => "User" + userId);

So, as you can see I use

It.IsAny<int>()

It.IsAny<int>()

It.IsAny<int>()

It.IsAny<int>() to mimic a value that would be passed, since

GetUserName()

GetUserName()

GetUserName()

GetUserName() requres an integer passed as argument.

However this value is not used in the actual mock, but rather the

string result = userManager.GetUserDisplayName(42);

string result = userManager.GetUserDisplayName(42);

string result = userManager.GetUserDisplayName(42);

string result = userManager.GetUserDisplayName(42);

the

42

42 that is passed here, which then calls

GetUserName()

GetUserName()

GetUserName()

GetUserName() inside of it.
