Assert.IsTrue

BernieTheBernie

Some people do not like mstest because it is so basic and hardly provides functionality...
Well, Bernie's coworker Kevin and David actually could do with an even more basic unit test suite:

Assert.IsTrue(connectionGuard.ConnectionStatus == ConnectionStatus.Connected);
Assert.IsTrue(connectionGuard.ConnectionStatus == ConnectionStatus.Disconnected);
Assert.IsTrue(tableNames.Contains("somename"));
Assert.IsTrue(dataFieldDefinition.FieldName == "TestName" && dataFieldDefinition.FieldType == typeof(DateTime) && dataFieldDefinition.IsKey);
Assert.IsTrue(dataFieldDefinitions.Contains(dataField.FieldDefinition));
Assert.IsTrue(blobValue[0] == 1 && blobValue[1] == 2 && blobValue[2] == 3 && blobValue[3] == 4 && blobValue[4] == (byte)intValue);
Assert.IsTrue(tempRange.Minimum == dummyTempRanges[tempRangeIdx].Item1 && tempRange.Maximum == dummyTempRanges[tempRangeIdx].Item2);

Why do you need

Assert.AreEqual
CollectionAssert.Contains

or even the extensions Bernie wrote like

AssertExtensions.IsGreaterThan
AssertExtensions.IsLessThan

when you can reduce everything to a simple Assert.IsTrue?

@homobalkanus I don't think the code sample includes the lines between…

(Also, if this was Python — it isn't of course, I know, I know — then just using assert would be reasonable; at least one test suite runner can drill down into the expression that produced the assertion failure anyway and that's pretty nice. One of the best things about the language…)

@berniethebernie Syntactic sugar. And the failure messages are tailored to the specific asserts: Assert.AreEqual(foo, <stuff to test>) produces something like "Assert.AreEqual failed: expected foo, actual bar".

@khudzlin Did you answer a rhetorical question?

Probably 2 in this thread now.
