I am trying to test this behavior
-- BLOGTableAdapter.GetBlogsByTitle(string title) is called and for once only
-- and is called with string having length greater than 1,
-- and it returns BLOGDataTable Object
[Test]
public void GetBlogsByBlogTitleTest4()
{
var mockAdapter = new Mock<BLOGTableAdapter>();
var mockTable = new Mock<BLOGDataTable>();
mockAdapter.Setup(x => x.GetBlogsByTitle(It.Is<string>(s => s.Length > 0))).Returns(mockTable.Object);
var blogBl = new BlogManagerBLL(mockAdapter.Object);
blogBl.GetBlogsByBlogTitle("Thanks for reading my question");
mockAdapter.VerifyAll();
mockAdapter.Verify(x => x.GetBlogsByTitle(It.Is<string>(s => s.Length > 0)), Times.Exactly(1));
}
When a calls is made to GetBlogsByTitle(string title), in class say "BlogManagerBLL" in Data Aceess Layer
public BLOGDataTable GetBlogsByBlogTitle(string title)
{
return Adapter.GetBlogsByTitle(title);
}
As you can see, I am using two seperate statements to get these checks done
mockAdapter.Setup(x => x.GetBlogsByTitle(It.Is<string>(s => s.Length > 0))).Returns(mockTable.Object);
mockAdapter.Verify(x => x.GetBlogsByTitle(It.Is<string>(s => s.Length > 0)), Times.Exactly(1));
Thanks
If you're testing two things, you should write two tests.
[Test]
public void BlogTableAdapter_should_be_called_with_string_having_length_greater_than_1()
{
var mockAdapter = new Mock<BLOGTableAdapter>();
var blogBl = new BlogManagerBLL(mockAdapter.Object);
blogBl.GetBlogsByBlogTitle("Thanks for reading my question");
mockAdapter.Verify(x => x.GetBlogsByTitle(It.Is<string>(s => s.Length > 0)));
}
and
[Test]
public void BlogTableAdapter_should_return_a_BLOGDataTable_object()
{
var mockAdapter = new Mock<BLOGTableAdapter>();
mockAdapter.Setup(x => x.GetBlogsByTitle(It.Is<string>(s => s.Length > 0))).Returns(new BLOGDataTable());
var blogBl = new BlogManagerBLL(mockAdapter.Object);
var returnValue = blogBl.GetBlogsByBlogTitle("Thanks for reading my question");
Assert.That(returnValue, Is.TypeOf(typeof(BLOGDataTable)));
}
So I guess my advice is don't put them together, create a test for each. And I'd say you're testing the right things.
