Property	Value
Rule ID	PosInfoMoq1000
Title	VerifyAll() methods should be called when instantiate a Mock instances
Category	Design
Default severity	Warning

Cause

A VerifyAll() of an Mock<T> instance has not been called in the Assert phase of an unit test.

Rule description

When instantiating a Mock<T> in the Arrange phase of an unit test, VerifyAll() method should be called in the Assert phase to check the setup methods has been called.

[Fact]
public void SendMail_ShouldCallSmtpService()
{
	// Arrange
	var smtpService = new Mock<ISmtpService>();
	smtpService.Setup(s => s.SendMail("[email protected]", "Gilles"));

	var service = new CustomerService(smtpService.Object);

	// Act
	service.SendMail("Gilles");

	// Assert
	smtpService.VerifyAll();	// The VerifyAll() will check that the mocked ISmtpService.SendMail() has been called.
}

How to fix violations

To fix a violation of this rule, call the VerifyAll() in the Assert phase on the Mock<T> instances created during the Arrange phase.

When to suppress warnings

Do not suppress a warning from this rule. Normally all setup methods must be call.
