  • Unit Testing VS 2008 Using Excel

    - by David
    When using Excel (2003) to provide data for my unit tests it seems to think that when a cell has TRUE / FALSE value that it is null when there has been no preceding cell values e.g. if (TestContext.DataRow["SatisfactionExtremelySatisfied"] != DBNull.Value) model.SatisfactionExtremelySatisfied = (bool)TestContext.DataRow ["SatisfactionExtremelySatisfied"]; Sample Excel Data DataRow SatisfactionExtremelySatisfied 0 1 2 TRUE 3 TRUE When reading the test data using OLEDB the cells with TRUE hold no value but when the preceding cells have the value FALSE entered it correctly gets the values TRUE. Am I missing something?

  • Unit Testing Interfaces in Python

    - by Nicholas Mancuso
    I am currently learning python in preperation for a class over the summer and have gotten started by implementing different types of heaps and priority based data structures. I began to write a unit test suite for the project but ran into difficulties into creating a generic unit test that only tests the interface and is oblivious of the actual implementation. I am wondering if it is possible to do something like this.. suite = HeapTestSuite(BinaryHeap()) suite.run() suite = HeapTestSuite(BinomialHeap()) suite.run() What I am currently doing just feels... wrong (multiple inheritance? ACK!).. class TestHeap: def reset_heap(self): self.heap = None def test_insert(self): self.reset_heap() #test that insert doesnt throw an exception... for x in self.inseq: self.heap.insert(x) def test_delete(self): #assert we get the first value we put in self.reset_heap() self.heap.insert(5) self.assertEquals(5, self.heap.delete_min()) #harder test. put in sequence in and check that it comes out right self.reset_heap() for x in self.inseq: self.heap.insert(x) for x in xrange(len(self.inseq)): val = self.heap.delete_min() self.assertEquals(val, x) class BinaryHeapTest(TestHeap, unittest.TestCase): def setUp(self): self.inseq = range(99, -1, -1) self.heap = BinaryHeap() def reset_heap(self): self.heap = BinaryHeap() class BinomialHeapTest(TestHeap, unittest.TestCase): def setUp(self): self.inseq = range(99, -1, -1) self.heap = BinomialHeap() def reset_heap(self): self.heap = BinomialHeap() if __name__ == '__main__': unittest.main()

  • Problem with routes in functional testing

    - by Wishmaster
    Hi, I'm making a simple test project to prepare myself for my test. I'm fairly new to nested resources, in my example I have a newsitem and each newsitem has comments. The routing looks like this: resources :comments resources :newsitems do resources :comments end I'm setting up the functional tests for comments at the moment and I ran into some problems. This will get the index of the comments of a newsitem. @newsitem is declared in the setup ofc. test "should get index" do get :index,:newsitem_id => @newsitem assert_response :success assert_not_nil assigns(:newsitem) end But the problem lays here, in the "should get new". test "should get new" do get new_newsitem_comment_path(@newsitem) assert_response :success end I'm getting the following error. ActionController::RoutingError: No route matches {:controller=>"comments", :action=>"/newsitems/1/comments/new"} But when I look into the routes table, I see this: new_newsitem_comment GET /newsitems/:newsitem_id/comments/new(.:format) {:action=>"new", :controller=>"comments"} Can't I use the name path or what I'm doing wrong here? Thanks in advance.

  • Unit testing directory structure

    - by zachary
    Huge project tons of classes and directories. Do I make my unit test project mirror these directories or do I put them all at the root directory? Somewhat annoying to have to make directory changes and class name changes twice.

  • How can unit testing make parameter validation redundant?

    - by Johann Gerell
    We have a convention to validate all parameters of constructors and public functions/methods. For mandatory parameters of reference type, we mainly check for non-null and that's the chief validation in constructors, where we set up mandatory dependencies of the type. The number one reason why we do this is to catch that error early and not get a null reference exception a few hours down the line without knowing where or when the faulty parameter was introduced. As we start transitioning to more and more TDD, some team members feel the validation is redundant. Uncle Bob, who is a vocal advocate of TDD, strongly advices against doing parameter validation. His main argument seems to be "I have a suite of unit tests that makes sure everything works". But I can for the life of it just not see in what way unit tests can prevent our developers from calling these methods with bad parameters in production code. Please, unit testers out there, if you could explain this to me in a rational way with concrete examples, I'd be more than happy to seize this parameter validation!

  • Unit testing task queues in AppEngine

    - by Swizec Teller
    For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

  • Unit-testing a directive with isolated scope and bidirectional value

    - by unludo
    I want to unit test a directive which looks like this: angular.module('myApp', []) .directive('myTest', function () { return { restrict: 'E', scope: { message: '='}, replace: true, template: '<div ng-if="message"><p>{{message}}</p></div>', link: function (scope, element, attrs) { } }; }); Here is my failing test: describe('myTest directive:', function () { var scope, compile, validHTML; validHTML = '<my-test message="message"></my-test>'; beforeEach(module('myApp')); beforeEach(inject(function($compile, $rootScope){ scope = $rootScope.$new(); compile = $compile; })); function create() { var elem, compiledElem; elem = angular.element(validHTML); compiledElem = compile(elem)(scope); scope.$digest(); return compiledElem; } it('should have a scope on root element', function () { scope.message = 'not empty'; var el = create(); console.log(el.text()); expect(el.text()).toBeDefined(); expect(el.text()).not.toBe(''); }); }); Can you spot why it's failing? The corresponding jsFiddle Thanks :)

  • Unit testing nested subflows (subflows of subflows)

    - by snusmumrik
    I'm trying to write unit test for a flow, which has subflow, which, itself, has another subflow. I register first flow using FlowDefinitionResource getResource(FlowDefinitionResourceFactory resourceFactory). Then I register subflow definitions during test execution in FlowDefinitionRegistry before transitioning to them. Transitioning to "first level" subflow goes ok. The result of transitioning to subflow of current subflow - NoSuchFlowDefinitionException. The problem is that subflow definitions are all seem attached to the primary flow of the test and subflow can't be found within another subflow. Is there any way to attach subflow definition to another subflow in tests, which extend AbstractXmlFlowExecutionTests?

  • Grails unit testing and bootstrap

    - by tbruyelle
    I wrote an unit test for a controller. I have a Bootstrap file which alter the metaclass of domain classes by adding a method asPublicMap(). I use this method in the controller to return domain classes as json but only some selected public fields. My unit test failed because of MissingMethodException for asPublicMap(). As I understood, bootstrap classes are not loaded for unit tests, only for integration tests. That's why I got this error. My question is : Is there another place to put metaclass manipulation in order to take them into account during unit tests ?

  • Testing variable types in Python

    - by Jasper
    Hello, I'm creating an initialising function for the class 'Room', and found that the program wouldn't accept the tests I was doing on the input variables. Why is this? def __init__(self, code, name, type, size, description, objects, exits): self.code = code self.name = name self.type = type self.size = size self.description = description self.objects = objects self.exits = exits #Check for input errors: if type(self.code) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 110' elif type(self.name) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 111' elif type(self.type) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 112' elif type(self.size) != type(int()): print 'Error found in module rooms.py!' print 'Error number: 113' elif type(self.description) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 114' elif type(self.objects) != type(list()): print 'Error found in module rooms.py!' print 'Error number: 115' elif type(self.exits) != type(tuple()): print 'Error found in module rooms.py!' print 'Error number: 116' When I run this I get this error: Traceback (most recent call last): File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa I/rooms.py", line 148, in <module> myRoom = Room(101, 'myRoom', 'Basic Room', 5, '<insert description>', myObjects, myExits) File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa I/rooms.py", line 29, in __init__ if type(self.code) != type(str()): TypeError: 'str' object is not callable

  • Strategies for testing reactive, asynchronous code

    - by Arne
    I am developing a data-flow oriented domain-specific language. To simplify, let's just look at Operations. Operations have a number of named parameters and can be asked to compute their result using their current state. To decide when an Operation should produce a result, it gets a Decision that is sensitive to which parameter got a value from who. When this Decision decides that it is fulfilled, it emits a Signal using an Observer. An Accessor listens for this Signal and in turn calls the Result method of the Operation in order to multiplex it to the parameters of other Operations. So far, so good, nicely decoupled design, composable and reusable and, depending on the specific Observer used, as asynchronous as you want it to be. Now here's my problem: I would love to start coding actual Tests against this design. But with an asynchronous Observer... how should I know that the whole signal-and-parameters-plumbing worked? Do I need to use time outs while waiting for a Signal in order to say that it was emitted successfully or not? How can I be, formally, sure that the Signal will not be emitted if I just wait a little longer (halting problem? ;-)) And, how can I be sure that the Signal was emitted because it was me who set a parameter, and not another Operation? It might well be that my test comes to early and sees a Signal that was emitted way before my setting a parameter caused a Decision to emit it. Currently, I guess the trivial cases are easy to test, but as soon as I want to test complex many-to-many - situations between operations I must resort to hoping that the design Just Works (tm)...

  • C# InternalsVisibleTo() attribute for VBNET 2.0 while testing?

    - by Will Marcouiller
    I'm building an Active Directory wrapper in VBNET 2.0 (can't use later .NET) in which I have the following: IUtilisateur IGroupe IUniteOrganisation These interfaces are implemented in internal classes (Friend in VBNET), so that I want to implement a façade in order to instiate each of the interfaces with their internal classes. This will allow the architecture a better flexibility, etc. Now, I want to test these classes (Utilisateur, Groupe, UniteOrganisation) in a different project within the same solution. However, these classes are internal. I would like to be able to instantiate them without going through my façade, but only for these tests, nothing more. Here's a piece of code to illustrate it: public static class DirectoryFacade { public static IGroupe CreerGroupe() { return new Groupe(); } } // Then in code, I would write something alike: public partial class MainForm : Form { public MainForm() { IGroupe g = DirectoryFacade.CreerGroupe(); // Doing stuff with instance here... } } // My sample interface: public interface IGroupe { string Domaine { get; set; } IList<IUtilisateur> Membres { get; } } internal class Groupe : IGroupe { private IList<IUtilisateur> _membres; internal Groupe() { _membres = new List<IUtilisateur>(); } public string Domaine { get; set; } public IList<IUtilisateur> Membres { get { return _membres; } } } I heard of InternalsVisibleTo() attribute, recently. I was wondering whether it is available in VBNET 2.0/VS2005 so that I could access the assmebly's internal classes for my tests? Otherwise, how could I achieve this?

  • Android Service Testing with messages

    - by Sandeep Dhull
    I have a service which does its work(perform network operation) depending upon the type of message(message.what) property of the message. Then it returns the resoponse, also as a message to the requesting component(depending upon the message.replyTo). So, i am trying to write the testcases.. But how????? My Architecture of service is like this: 1) A component(ex. Activity) bounds to the service. 2) The component sends message to the Service(using Messenger). 3) The service has a nested class that handles the messages and execute the network call and returns a response as message to the sender(who initially sent the message and using its replyTo property). Now to test this.. i am using Junit test cases.. So , in that .. 1) in setUp() i am binding to the service.. 2) on testBusinessLogic() . i am sending the message to the service .. Now problem is where to get the response message.

  • Do You Know How OUM defines the four, basic types of business system testing performed on a project? Why not test your knowledge?

    - by user713452
    Testing is perhaps the most important process in the Oracle® Unified Method (OUM). That makes it all the more important for practitioners to have a common understanding of the various types of functional testing referenced in the method, and to use the proper terminology when communicating with each other about testing activities. OUM identifies four basic types of functional testing, which is sometimes referred to as business system testing.  The basic functional testing types referenced by OUM include: Unit Testing Integration Testing System Testing, and  Systems Integration Testing See if you can match the following definitions with the appropriate type above? A.  This type of functional testing is focused on verifying that interfaces/integration between the system being implemented (i.e. System under Discussion (SuD)) and external systems functions as expected. B.     This type of functional testing is performed for custom software components only, is typically performed by the developer of the custom software, and is focused on verifying that the several custom components developed to satisfy a given requirement (e.g. screen, program, report, etc.) interact with one another as designed. C.  This type of functional testing is focused on verifying that the functionality within the system being implemented (i.e. System under Discussion (SuD)), functions as expected.  This includes out-of-the -box functionality delivered with Commercial Off-The-Shelf (COTS) applications, as well as, any custom components developed to address gaps in functionality.  D.  This type of functional testing is performed for custom software components only, is typically performed by the developer of the custom software, and is focused on verifying that the individual custom components developed to satisfy a given requirement  (e.g. screen, program, report, etc.) functions as designed.   Check your answers below: (D) (B) (C) (A) If you matched all of the functional testing types to their definitions correctly, then congratulations!  If not, you can find more information in the Testing Process Overview and Testing Task Overviews in the OUM Method Pack.

  • ISO 12207: Verification of integration and Unit test validation

    - by user970696
    I have received comments from the supervisor reviewing my thesis. He asked two questions I cannot answer right now: If ISO 12207 says under "Integration verification" that it "checks that components are correctly and completely integrated into a system", how this can be verified without testing, if all testing is validation? How without testing can I know that system is integrated correctly and fully? If unit testing is validation, how does it match the ISO definiton of validation "that requirements for intended use were fulfilled" if its so low level?

  • How Can I Point My Local Testing Server at My GitHub Repository?

    - by Goober
    Up until a few days ago, I had a particular setup that was as follows. Using SVN, all of the websites that I developed were committed to a source control drop box on a local testing server. Then using IIS, a new website was set up to point at the last revision of each particular website I developed and display it to the outside world using a specific URL. I have just moved over to using git and github, meaning all of my source controlled code is now no longer stored on a local testing server. As a result of this, I am not sure how I can go about doing a similar thing to what I did with the SVN setup, however I need to be able to essentially have that same setup again, just using Git. So basically, how can I go about getting my local testing server to point at the GitHub repository for that site? Help greatly appreciated.

  • What is the Optimal Server Configuration for Split-Path Testing?

    - by doug
    I am far from an expert on Apache or any server for that matter, so i apologize if this question is poorly worded, which it likely is. We have always relied on a vendor for split-path testing (aka "AB Testing"). If you're not familiar with that term, it's a form of marketing research in which you slightly modify one of your web pages (usually one nearest the point of conversion), say for instance, by changing the position of the "Buy Now" button or its color/contrast/texture, then serving one of those two pages to a given user based on random selection. By doing split-path testing ourselves, I suspect we can do it far more cheaply and increase cycle times as well. What is the optimal set-up for these tests? "Optimal" is based on the following criteria: how quickly/easily new tests can be set-up and put online; and minimal disruption to overall site performance

  • The art of Unit Testing with Examples in .NET

    - by outcoldman
    First time when I familiarized with unit testing was 5 or 6 years ago. It was start of my developing career. I remember that somebody told me about code coverage. At that time I didn’t write any Unit tests. Guy, who was my team lead, told me “Do you see operator if with three conditions? You should check all of these conditions”. So, after that I had written some code, I should go to interface and try to invoke all code which I wrote from user interface. Nice? At current time I know little more about tests and unit testing. I have not participated in projects, designed by Test Driven Development (TDD). Basics of my knowledge are a spying code of my colleagues, some articles and screencasts. I had decide that I should know much more, and became a real professional of unit testing, this is why I had start to read book The art of Unit Testing with Examples in .NET. More than, in my current job place looks like I’m just one who writing unit tests for my code. I should show good examples of my tests. ,a href="http://outcoldman.ru/en/blog/show/267"Read more...
