Why does it fail?

Question

"Message: Assert.Is True failed. Expected: System.Collections.Generic.List 1[...] but found System.Collections.Generic.List 1[...]"

I don't know why is it failing. Can anyone help me with this error please

        /// <summary>

                {
                    return new Microsoft.Xrm.Sdk.EntityCollection()
                    {
                        EntityName = entityname,
                        MoreRecords = true,
                        MinActiveRowVersion = "version",
                        PagingCookie = "paging cookie",
                        TotalRecordCount = 10,
                        TotalRecordCountLimitExceeded = false,
                    };
                });

                //Act              
                var AnnualBillingService = new AnnualBillingService();
                var response = AnnualBillingService.GetFeeBandingList();

                //Assert
                Assert.IsNotNull(response, "Expected not-null response");
                Assert.IsTrue(response.FeeBands == fee_bands, "Expected: " + fee_bands + " but found " + response.FeeBands);
                foreach (var FeeBands in fee_bands)
                {
                    Assert.IsTrue(FeeBands.Id == ID, "Expects True");
                }
            }
        }

Here is the code. I cannot understand the error, its strange that expected and actual result is the same and still getting error.

Answer 1

Maybe what you are looking for is Collection's assert methods, to compare collections of types. There is a difference between AreEqual and AreEquivalent and i am not pretty sure what your case is here, so take a look at them both!

Follow this link and you will find both methods and their documentation, it should help you enough. Clicky clicky

                Assert.IsTrue(response.FeeBands.Count == 1, "Expected: " + fee_bands + " but found " + response.FeeBands);
                foreach (var FeeBands in fee_bands)
                {

                }
            }
        }

Problem solved guys THANK YOU all:)
