我对Moq比较陌生,希望我只是遗漏了一些东西。出现了目标参数计数异常的问题。
你能看出我做错了什么吗?有任何疑问请问:)
这是我的代码:
[Test]
public void HasStudentTest_SaveToRepository_Then_HasStudentReturnsTrue()
{
var fakeStudents = new List<Student>();
fakeStudents.Add(new Student("Jim"));
mockRepository.Setup(r => r.FindAll<Student>(It.IsAny<Predicate<Student>>()))
.Returns(fakeStudents.AsQueryable<Student>)
.Verifiable();
// in persistence.HasStudent(), repo.FindAll(predicate) is throwing
// 'TargetParameterCountException' ; not sure why
persistence.HasStudent("Jim");
mockRepository.VerifyAll();
}
以下是 Persistence 中的 HasStudent 方法:
public bool HasStudent(string name)
{
// throwing the TargetParameterCountException
var query = Repository.FindAll<Student>(s => s.Name == name);
if (query.Count() > 1)
throw new InvalidOperationException("There should not be multiple Students with the same name.");
return query.Count() == 1;
}
