  • Find out which row caused the error

    - by Felipe Fiali
    I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

  • AutoFixture refactoring

    - by Thomas Jaskula
    I started to use AutoFixture http://autofixture.codeplex.com/ as my unit tests was bloated with a lot of data setup. I was spending more time on seting up the data than to write my unit test. Here's an example of how my initial unit test looks like (example taken from cargo application sample from DDD blue book) [Test] public void should_create_instance_with_correct_ctor_parameters() { var carrierMovements = new List<CarrierMovement>(); var deparureUnLocode1 = new UnLocode("AB44D"); var departureLocation1 = new Location(deparureUnLocode1, "HAMBOURG"); var arrivalUnLocode1 = new UnLocode("XX44D"); var arrivalLocation1 = new Location(arrivalUnLocode1, "TUNIS"); var departureDate1 = new DateTime(2010, 3, 15); var arrivalDate1 = new DateTime(2010, 5, 12); var carrierMovement1 = new CarrierMovement(departureLocation1, arrivalLocation1, departureDate1, arrivalDate1); var deparureUnLocode2 = new UnLocode("CXRET"); var departureLocation2 = new Location(deparureUnLocode2, "GDANSK"); var arrivalUnLocode2 = new UnLocode("ZEZD4"); var arrivalLocation2 = new Location(arrivalUnLocode2, "LE HAVRE"); var departureDate2 = new DateTime(2010, 3, 18); var arrivalDate2 = new DateTime(2010, 3, 31); var carrierMovement2 = new CarrierMovement(departureLocation2, arrivalLocation2, departureDate2, arrivalDate2); carrierMovements.Add(carrierMovement1); carrierMovements.Add(carrierMovement2); new Schedule(carrierMovements).ShouldNotBeNull(); } Here's how I tried to refactor it with AutoFixture [Test] public void should_create_instance_with_correct_ctor_parameters_AutoFixture() { var fixture = new Fixture(); fixture.Register(() => new UnLocode(UnLocodeString())); var departureLoc = fixture.CreateAnonymous<Location>(); var arrivalLoc = fixture.CreateAnonymous<Location>(); var departureDateTime = fixture.CreateAnonymous<DateTime>(); var arrivalDateTime = fixture.CreateAnonymous<DateTime>(); fixture.Register<Location, Location, DateTime, DateTime, CarrierMovement>( (departure, arrival, departureTime, arrivalTime) => new CarrierMovement(departureLoc, arrivalLoc, departureDateTime, arrivalDateTime)); var carrierMovements = fixture.CreateMany<CarrierMovement>(50).ToList(); fixture.Register<List<CarrierMovement>, Schedule>((carrierM) => new Schedule(carrierMovements)); var schedule = fixture.CreateAnonymous<Schedule>(); schedule.ShouldNotBeNull(); } private static string UnLocodeString() { var stringBuilder = new StringBuilder(); for (int i = 0; i < 5; i++) stringBuilder.Append(GetRandomUpperCaseCharacter(i)); return stringBuilder.ToString(); } private static char GetRandomUpperCaseCharacter(int seed) { return ((char)((short)'A' + new Random(seed).Next(26))); } I would like to know if there's better way to refactor it. Would like to do it shorter and easier than that.

  • Mockito verify no more interactions but omit getters

    - by michael lucas
    Mockito api provides method: Mockito.verifyNoMoreInteractions(someMock); but is it possible in Mockito to declare that I don't want more interactions with a given mock with the exceptions of interactions with its getter methods? The simple scenario is the one in which I test that sut changes only certain properties of a given mock and lefts other properties untapped. In example I want to test that UserActivationService changes property Active on an instance of class User but does't do anything to properties like Role, Password, AccountBalance, etc. I'm open to criticism regarding my approach to the problem.

  • How do I assert that two arbitrary type objects are equivalent, without requiring them to be equal?

    - by Tomas Lycken
    To accomplish this (but failing to do so) I'm reflecting over properties of an expected and actual object and making sure their values are equal. This works as expected as long as their properties are single objects, i.e. not lists, arrays, IEnumerable... If the property is a list of some sort, the test fails (on the Assert.AreEqual(...) inside the for loop). public void WithCorrectModel<TModelType>(TModelType expected, string error = "") where TModelType : class { var actual = _result.ViewData.Model as TModelType; Assert.IsNotNull(actual, error); Assert.IsInstanceOfType(actual, typeof(TModelType), error); foreach (var prop in typeof(TModelType).GetProperties()) { Assert.AreEqual(prop.GetValue(expected, null), prop.GetValue(actual, null), error); } } If dealing with a list property, I would get the expected results if I instead used CollectionAssert.AreEquivalent(...) but that requires me to cast to ICollection, which in turn requries me to know the type listed, which I don't (want to). It also requires me to know which properties are list types, which I don't know how to. So, how should I assert that two objects of an arbitrary type are equivalent? Note: I specifically don't want to require them to be equal, since one comes from my tested object and one is built in my test class to have something to compare with.

  • Getting Unit Tests to work with Komodo IDE for Python

    - by devoured elysium
    I've tried to run the following code on Komodo IDE (for python): import unittest class MathLibraryTests(unittest.TestCase): def test1Plus1Equals2(self): self.assertEqual(1+1, 2) Then, I created a new test plan, pointing to this project(file) directory and tried to run it the test plan. It seems to run but it doesn't seem to find any tests. If I try to run the following code with the "regular" run command (F7) class MathLibraryTests(unittest.TestCase): def testPlus1Equals2(self): self.assertEqual(1+1, 2) if __name__ == "__main__": unittest.main() it works. I get the following output: ---------------------------------------------------------------------- Ran 1 test in 0.000s OK What might I be doing wrong?

  • How to compare the output of serializeArray using qunit

    - by dorelal
    I am using qunit and jquery. Latest version of both. In my code when I submit the form I have the event as e. I call e.serializeArray() Here is my test. equals(args.data, [ { "name": "user_name", "value": "john" } ], 'input data'); And this is the error message from qunit. expected: [ { "name": "user_name", "value": "david" } ] result: [ { "name": "user_name", "value": "david" } ] As you can see to the naked eye the expected and result value is same but qunit is not liking it. I guess I am missing something.

  • Mocking HtmlHelper throws NullReferenceException

    - by Matt Austin
    I know that there are a few questions on StackOverflow on this topic but I haven't been able to get any of the suggestions to work for me. I've been banging my head against this for two days now so its time to ask for help... The following code snippit is a simplified unit test to demonstrate what I'm trying to do, which is basically call RadioButtonFor in the Microsoft.Web.Mvc assembly in a unit test. var model = new SendMessageModel { SendMessageType = SendMessageType.Member }; var vd = new ViewDataDictionary(model); vd.TemplateInfo = new TemplateInfo { HtmlFieldPrefix = string.Empty }; var controllerContext = new ControllerContext(new Mock<HttpContextBase>().Object, new RouteData(), new Mock<ControllerBase>().Object); var viewContext = new Mock<ViewContext>(new object[] { controllerContext, new Mock<IView>().Object, vd, new TempDataDictionary(), new Mock<TextWriter>().Object }); viewContext.Setup(v => v.View).Returns(new Mock<IView>().Object); viewContext.Setup(v => v.ViewData).Returns(vd).Callback(() => {throw new Exception("ViewData extracted");}); viewContext.Setup(v => v.TempData).Returns(new TempDataDictionary()); viewContext.Setup(v => v.Writer).Returns(new Mock<TextWriter>().Object); viewContext.Setup(v => v.RouteData).Returns(new RouteData()); viewContext.Setup(v => v.HttpContext).Returns(new Mock<HttpContextBase>().Object); viewContext.Setup(v => v.Controller).Returns(new Mock<ControllerBase>().Object); viewContext.Setup(v => v.FormContext).Returns(new FormContext()); var mockContainer = new Mock<IViewDataContainer>(); mockContainer.Setup(x => x.ViewData).Returns(vd); var helper = new HtmlHelper<ISendMessageModel>(viewContext.Object, mockContainer.Object, new RouteCollection()); helper.RadioButtonFor(m => m.SendMessageType, "Member", cssClass: "selector"); If I remove the cssClass parameter then the code works ok but fails consistently when adding additional parameters. I've tried every combination of mocking, instantiating concrete types and using fakes that I can think off but I always get a NullReferenceException when I call RadioButtonFor. Any help hugely appreciated!!

  • Are unit tests also used to find bugs?

    - by Draco
    I was reading the following article and the author made it quite clear that unit tests are NOT used to find bugs. I would like to know what your thoughts are on this. I do know that unit tests makes the design of your application much more robust but isn't it the fact that finding bugs through unit tests that make the application robust, besides its other advantages? http://blog.stevensanderson.com/2009/08/24/writing-great-unit-tests-best-and-worst-practises/

  • Creating a context in custom shoulda macro does not work.

    - by Honza
    I have a custom should macro in my test_helper.rb which looks like this. def self.should_require_login(actions = [:index]) if (actions.is_a? Symbol) actions = [actions] end context "without user" do actions.each do |action| should "redirect #{action.to_s} away" do get action assert_redirected_to login_path end end end if block_given? context "active user logged in" do setup do @user = Factory.create(:user) @user.register! @user.activate! login_as(@user) end yield end end end I would like to use it like this: should_require_login(:protected_action) do should "do something" do ... end end And I am expecting the "do something" test to run in the "active user logged in" context, but the test executes in the top context, like the "active user logged in" context never existed and I fail to see the reason why.

  • Rails "rake test" crashing

    Hi, this might be rather unspecific, but I'm trying to do 'rake test' on a new rails app, and end up with (in /Users/myname/dev/railstest/RailsApplication1) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I"lib:test" "/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I"lib:test" "/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -I"lib:test" "/Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" No other output. System is Leopard 10.5, Rails 2.3.5, Ruby 1.86 Any ideas ?

  • ReSharper Unit Test Runner: Support for Deployment Items

    - by driis
    I like the Unit test runner in ReSharper 4.5, and would like to use it with my MSTest tests, but one thing annoys me: In some of our solutions, we have set up some Deployment Items in the .testrunconfig file. The ReSharper Unit Test runner does not seem to respect this, so I get errors when trying to run the unit tests from ReSharper. Is there any workraound for this ? Update: citizenmatt's answer was correct, the option to use a .testrunconfig with ReSharper exists in the Options dialog of ReSharper. You have to select the unit test provider on the list, then the controls to do that appears. (That was not obvious or discoverable, at least not for me ;-)

  • How to unit test internals (organization) of a data structure?

    - by Herms
    I've started working on a little ruby project that will have sample implementations of a number of different data structures and algorithms. Right now it's just for me to refresh on stuff I haven't done for a while, but I'm hoping to have it set up kind of like Ruby Koans, with a bunch of unit tests written for the data structures but the implementations empty (with full implementations in another branch). It could then be used as a nice learning tool or code kata. However, I'm having trouble coming up with a good way to write the tests. I can't just test the public behavior as that won't necessarily tell me about the implementation, and that's kind of important here. For example, the public interfaces of a normal BST and a Red-Black tree would be the same, but the RB Tree has very specific data organization requirements. How would I test that?

  • using ruby test and selenium grid how can I keep the same browser window for multiple tests?

    - by George Horlacher
    Each of my tests start a new selenium client browser and tear it down so they can run stand alone with this code: def setup if $selenium @selenium = $selenium else @selenium = Selenium::SeleniumDriver.new("#$sell_server", 4444, "#$browser", "http://#$network.#$host:2086", 10000); @selenium.start end @selenium.set_context("test_login") end def teardown @selenium.stop unless $selenium assert_equal [], @verification_errors end What I'd like is to run a suite of tests that all use the same browser and don't keep opening and closing new browsers for every test. I've tried using $selenium as a global object / browser but each test still opens up a new browser and closes it. How should this be done?

  • Using Moq to set indexers in C#

    - by emddudley
    I'm having trouble figuring out how to set indexers in C# with Moq. The Moq documentation is weak, and I've done a lot of searching... what I'd like to do is similar in the solution to How to Moq Setting an Indexed property: var someClass = new Mock<ISomeClass>(); someClass.SetupSet(o => o.SomeIndexedProperty[3] = 25); I want to modify the above to work for any index and any value so I can just do something like this: someClass.Object.SomeIndexedProperty[1] = 5; Currently I have the following, which works great for the indexed property getter, but if I ever set the value Moq ignores it: var someValues = new int[] { 10, 20, 30, 40 }; var someClass = new Mock<ISomeClass>(); someClass.Setup(o => o.SomeIndexedProperty[It.IsAny<int>()]) .Returns<int>(index => someValues[index]); // Moq doesn't set the value below, so the Assert fails! someClass.Object.SomeIndexedProperty[3] = 25; Assert.AreEqual(25, someClass.Object.SomeIndexedProperty[3]);

  • Setting up a web developer lab for learning purposes

    - by Saleh Al-Abbas
    I'm not a developer by profession. Therefore, I'm not exposed to real world technical problems that face professional developers. I read/heard about web farms, integration between different systems, load balancing ... etc. Therefore, I was wondering if there are ways for the individual developer to create an environment that simulates real world situations with minimal number of machines like: web farms & caching simulating many users accessing your website (Pressure tests?) Performance load balancing anything you think I should consider. By the way, I have a server machine and 1 PC. and I don't mind investing in tools and software. PS. I'm using Microsoft technologies for development but I hope this is not a limiting factor. Thanks

They say it's possible, but I have no idea.

  • Running PHP Zend Test in Eclipse

    Is it possible to run PHP Zend test cases (those that extend Zend_Test_PHPUnit_ControllerTestCase, etc.) through Eclipse PDT? I would like to be able to run them in a similar fashion as you run JUnit tests in Eclipse, by right-clicking the test file and selecting "Run as a JUnit test case." I'd love to see the green or red bar instead of having to go to the command line :). Thanks in advance.
