assertion

I am trying to create a log system on my program that will log debugging messages on text files, and I want to save the exact place in the code where the log message called, but I don't want to use Assert function because it creates exceptions and this system is not for logging exceptions only, also I have to write some debugging info. example usning assert: procedure AnyProcedure(); begin try Assert(1=0); except on E: Exception do Log.AddLine('Log occurred is '+E.Message+' : Start');//Log occurred is "c:\progr~..jkdj.pas" at line [29] end; //....some code try Assert(1=0); except on E:

I have two Json objects as below need to be compared. I am using Newtonsoft libraries for Json parsing. string InstanceExpected = jsonExpected; string InstanceActual = jsonActual; var InstanceObjExpected = JObject.Parse(InstanceExpected); var InstanceObjActual = JObject.Parse(InstanceActual); And I am using Fluent Assertions to compare it. But the problem is Fluent assertion fails only when the attribute count/names are not matching. If the json values are different it passes. I require to fail when values are different. InstanceObjActual.Should().BeEquivalentTo(InstanceObjExpected); For

I was just wondering how I would go about testing for a function that does not return anything. for example, say I have this function: def is_in(char): my_list = [] my_list.append(char) and then if I were to test it: class TestIsIn(unittest.TestCase): def test_one(self): ''' Test if one character was added to the list''' self.assertEqual(self.is_in('a'), and this is where I am lost) I don't know what to assert the function is equal to, since there is no return value that I could compare it to. EDIT: would assertIn work? All Python functions return something. If you don't specify a return value

How can I write a custom assertion, like assertFoo($expected, $actual) , that behaves like the built-in assertions with respect to the error "stack trace"? I currently have the following method defined (within a class that extends PHPUnit_Framework_TestCase ): public static function assertFoo($expected, $actual) { self::assertEquals($expected, $actual); } If I call this from a test and the test fails, I get two items in the call stack: 1) PreferencesTest::testSignupTeacher Failed asserting that 5 matches expected 3. /vagrant/myproject/tests/integration/PreferencesTest.php:17 /vagrant/myproject

I know why assertive programming is good, so I want to use it with JavaScript. However, I don't want to show users error boxes, and it's unusual thing. Just ignore it and make them retry could be better. For example this code will make an error box and interrupt users. function getDomainFromURL(url) { assertTrue(url, 'URL should not be null'); ...parsing } So, I'd make like this. function getDomainFromURL(url) { if (!url) return; ...parsing } Second one is good for usability, I think, and first one is good for developing. Therefore, IMO it would be the best to combine these and make the assert

I had a question like this on one of my exams and I'm still not too sure how to answer it. I understand that assertions are ways to test your program, however I'm not too sure what assert(0) is checking. Is this a trick question? It will always fail, but I don't understand why. What is it checking? Any explanation would be great, thanks. It will always fail. That's pretty much it. It will fail always for the same reason that "assert(x == 5)" will succeed whenever x = 5. If you're asking for an application then you would put it in code blocks that really shouldn't happen. switch(suit) { case
