  • Embedded systems code with good unit tests?

    - by rmk
    I am looking at approaches to Unit Test embedded systems code written in C. At the same time, I am also looking for a good UT framework that I can use. The framework should have a reasonably small number of dependencies. Any great Open-source products that have good UTs?

  • Google Toolbox For Mac with Core Data on iPhone results in error

    - by JaanusSiim
    I have set up my project for using Google Toolbox for Mac as described on official wiki. And everything is working as expected. For core data usage I have created a 'database' class that uses for final application SQLite storage (this is done based on Xcode template code). For unit tests I have created separate init method for 'database' to use in memory storage (storage url is [NSURL URLWithString:@"memory://store"] and type NSInMemoryStoreType). Without adding my model file (*.xcdatamodel) to unit tests target, test fail in expected place with message: executeFetchRequest:error: A fetch request must have an entity. If I add model file to the test target, then test is executed as expected (core data part looks OK), but after tests execution I get: RunIPhoneUnitTest.sh: line 123: 9487 Segmentation fault "$TARGET_BUILD_DIR/$EXECUTABLE_PATH" -RegisterForSystemEvents Command /bin/sh failed with exit code 139 This problem does not looks directly related to core data, but only happens if model file is added to target. Any pointers on resolving this issue would be appreciated!

  • How to test custom template tags in Django?

    - by Mark Lavin
    I'm adding a set of template tags to a Django application and I'm not sure how to test them. I've used them in my templates and they seem to be working but I was looking for something more formal. The main logic is done in the models/model managers and has been tested. The tags simply retrieve data and store it in a context variable such as {% views_for_object widget as views %} """ Retrieves the number of views and stores them in a context variable. """ # or {% most_viewed_for_model main.model_name as viewed_models %} """ Retrieves the ViewTrackers for the most viewed instances of the given model. """ So my question is do you typically test your template tags and if you do how do you do it?

  • missing value true / false: error in loop not in one-off

    - by vincent hay
    I am new on R and I have a problem with a test in a loop that I want to code. With a data frame (tabetest) like the one here after: Date 25179M103 1 14977 77.7309 2 14978 77.2567 3 14979 77.7507 I have: if(tabetest[3,"Date"]-tabetest[1,"Date"]1){print("ok")} [1] "ok" But: j=1 > position = 1 > price=tabetest for (i in 1:nrow(tabetest)-position){if(tabetest[i+position,"Date"]-tabetest[position,"Date"]>20){price[i+position,j]=price[i+position,j]/price[position,j]-1};position=position+1} Returns an error. R says that there is a missing value where true/false is required in: if (tabetest[i + position, "Date"] - tabetest[position, "Date"] > I have spent quite some time on that error but still don't understand where it comes from. Thanks for your help, Vincent

  • Using Moq callbacks correctly according to AAA

    - by Hadi Eskandari
    I've created a unit test that tests interactions on my ViewModel class in a Silverlight application. To be able to do this test, I'm mocking the service interface, injected to the ViewModel. I'm using Moq framework to do the mocking. to be able to verify bounded object in the ViewModel is converted properly, I've used a callback: [Test] public void SaveProposal_Will_Map_Proposal_To_WebService_Parameter() { var vm = CreateNewCampaignViewModel(); var proposal = CreateNewProposal(1, "New Proposal"); Services.Setup(x => x.SaveProposalAsync(It.IsAny<saveProposalParam>())).Callback((saveProposalParam p) => { Assert.That(p.plainProposal, Is.Not.Null); Assert.That(p.plainProposal.POrderItem.orderItemId, Is.EqualTo(1)); Assert.That(p.plainProposal.POrderItem.orderName, Is.EqualTo("New Proposal")); }); proposal.State = ObjectStates.Added; vm.CurrentProposal = proposal; vm.Save(); } It is working fine, but if you've noticed, using this mechanism the Assert and Act part of the unit test have switched their parts (Assert comes before Acting). Is there a better way to do this, while preserving correct AAA order?

  • Loading SQL dump before running Django tests

    - by knutin
    I have a fairly complex Django project which makes it hard/impossible to use fixtures for loading data. What I would like to do is to load a database dump from the production database server after all tables has bene created by the testrunner and before the actual tests start running. I've tried various "magic" in MyTestCase.setUp(), but with no luck. Any suggestions would be most welcome. Thanks.

  • Getting HTTP 406 when trying to test facebooker application with cucumber

    - by Waseem
    I am trying to test facebook api calls with cucumber. Here is the code. # app/controller/facebook_users_controller.rb class FacebookUsersController < ApplicationController def create fb_user = facebook_session.user user = User.new(:facebook_uid => fb_user.uid, :facebook_session_key => facebook_session.session_key respond_to do |format| if user.save format.json { render :json => { :status => 'ok' }.to_json } end end end end # features/steps/facebook_connect_step.rb Given /^I am a facebook connected user$/ do mock_session = Facebooker::MockSession.create post('/facebook_user.json') puts response.code end When I run the cucumber step for above step definition, I get a response code of 406 instead of 200. This happens in the cucumber test environment only and not in the browser(development/production).

  • Passing custom Python objects to nosetests

    - by Rob
    I am attempting to re-organize our test libraries for automation and nose seems really promising. My question is, what is the best strategy for passing Python objects into nose tests? Our tests are organized in a testlib with a bunch of modules that exercise different types of request operations. Something like this: testlib \-testmoda \-testmodb \-testmodc In some cases the test modules (i.e. testmoda) is nothing but test_something(), test_something2() functions while in some cases we have a TestModB class in testmob with the test_anotherthing1(), test_anotherthing2() functions. The cool thing is that nose easily finds both. Most of those test functions are request factory stuff that can easily share a single connection to our server farm. Thus we do a lot of test_something1(cnn), TestModB.test_anotherthing2(cnn), etc. Currently we don't use nose, instead we have a hodge-podge of homegrown driver scripts with hard-coded lists of tests to execute. Each of those driver scripts creates its own connection object. Maintaining those scripts and the connection minutia is painful. I'd like to take free advantage of nose's beautiful discovery functionality, passing in a connection object of my choosing. Thanks in advance! Rob P.S. The connection objects are not pickle-able. :(

  • How do I test an image alt value using capybara?

    - by stayce
    I'm trying to define a step to test the value of alt text of an image using capybara and the css selectors. I wrote one for input values based on the readme examples: Then /^I should see a value of "([^\"])" within the "([^\"])" input$/ do |input_value, input_id| element_value = locate("input##{input_id}").value element_value.should == input_value end But I can't figure this one out...something like: Then /^I should see the alttext "([^\"]*)"$/ do | alt_text | element_value = locate("img[alt]").value Anyone know how I can locate the alt text value?

  • Nielson's usablity scale

    - by Banderdash
    Just wondering if anyone out there knows of a standard survey (preferably based off Jacob Nielson's work on usability) that web admin's can administer to test groups for usability? I could just make up my own but I feel there as got to be some solid research out there on the sort of judgments on tasks I should be asking. For example Q:: Ask user to find profile page Do I ... A.) Present them with standard likert scale after each question B.) Present them the likert after all the questions .. Then what should that likert be, I know Nielson's usability judgments scale is based on Learnability, Efficiency of Use, Memorability, Error Rate, Satisfaction but I can only imagine a likert I would design that would effectively measure satisfaction...how am I suppose to ask a user to rank the Memorability of a site after one use on a 1-5 scale? Surely someone has devised a good way to pose the question?

  • Django tests failing on invalid keyword argument

    - by Darwin Tech
    I have a models.py like so: from django.db import models from django.contrib.auth.models import User from datetime import datetime class UserProfile(models.Model): user = models.OneToOneField(User) def __unicode__(self): return self.user.username class Project(models.Model): user = models.ForeignKey(UserProfile) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) product = models.ForeignKey('tool.product') module = models.ForeignKey('tool.module') model = models.ForeignKey('tool.model') zipcode = models.IntegerField(max_length=5) def __unicode__(self): return unicode(self.id) And my tests.py: from django.test import TestCase, Client # --- import app models from django.contrib.auth.models import User from tool.models import Module, Model, Product from user_profile.models import Project, UserProfile # --- unit tests --- # class UserProjectTests(TestCase): fixtures = ['admin_user.json'] def setUp(self): self.product1 = Product.objects.create( name='bar', ) self.module1 = Module.objects.create( name='foo', enable=True ) self.model1 = Model.objects.create( module=self.module1, name='baz', enable=True ) self.user1 = User.objects.get(pk=1) ... def test_can_create_project(self): self.project1 = Model.objects.create( user=self.user1, product=self.product1, module=self.module1, model=self.model1, zipcode=90210 ) self.assertEquals(self.project1.zipcode, 90210) But I get a TypeError: 'product' is an invalid keyword argument for this function error. I'm not sure what is failing but I'm guessing something to do with the FK relationships... Any help would be much appreciated.

  • eclEmma - full code coverage on class header?

    - by Fork
    Hi, I have a class that starts with: public class GeneralID implements WritableComparable<GeneralID>{ ... } And another that is: public class LineValuesMapper<KI, VI, KO, VO> extends Mapper<LongWritable, Text, Text, IntWritable>{ ... } All methods in these classes are covered. But not their header. The header of both classes gets painted as yellow with EclEmma. Is there anything I can do to fully cover the class header?

  • Mocking inter-method dependencies

    - by Zecrates
    I've recently started using mock objects in my tests, but I'm still very inexperienced with them and unsure of how to use them in some cases. At the moment I'm struggling with how to mock inter-method dependencies (calling method A has an effect on the results of method B), and whether it should even be mocked (in the sense of using a mocking framework) at all? Take for example a Java Iterator? It is easy enough to mock the next() call to return the correct values, but how do I mock hasNext(), which depends on how many times next() has been called? Currently I'm using a List.Iterator as I could find no way to properly mock one. Does Martin Fowler's distinction between mocks and stubs come into play here? Should I rather write my own IteratorMock? Also consider the following example. The method to be tested calls mockObject.setX() and later on mockObject.getX(). Is there any way that I can create such a mock (without writing my own) which will allow the returned value of getX to depend on what was passed to setX?

  • Re-using unit tests for models using STI

    - by TenJack
    I have a number of models that use STI and I would like to use the same unit test to test each model. For example, I have: class RegularList < List class OtherList < List class ListTest < ActiveSupport::TestCase fixtures :lists def test_word_count list = lists(:regular_list) assert_equal(0, list.count) end end How would I go about using the test_word_count test for the OtherList model. The test is much longer so I would rather not have to retype it for each model. Thanks.

  • Unit test with Authlogic on Rails 3

    - by Puru puru rin..
    Hello, I would like to write some unit test with a logged user using Authlogic. To start right, I used some code hosted in http://github.com/binarylogic/authlogic_example. But I get an error after rake test, because of "test_helper.rb" and the following class: class ActionController::TestCase setup :activate_authlogic end Here is my error: NameError: undefined local variable or method `activate_authlogic' for I think this Authlogic example is mapped over Rails 2; maybe it's a little bit different on Rails 3. Is there an other example where I can take example about unit test? Many thanks.

  • Zend_Test_PHPUnit_ControllerTestCase: Test view parameters and not rendered output

    - by erenon
    Hi, I'm using Zend_Test_PHPUnit_ControllerTestCase to test my controllers. This class provides various ways to test the rendered output, but I don't want to get my view scripts involved. I'd like to test my view's vars. Is there a way to access to the controllers view object? Here is an example, what I'm trying to do: <?php class Controller extends Zend_Controller_Action { public function indexAction() { $this-view->foo = 'bar'; } } class ControllerTest extends Zend_Test_PHPUnit_ControllerTestCase { public function testShowCallsServiceFind() { $this->dispatch('/controller'); //doesn't work, there is no such method: $this->assertViewVar('foo', 'bar'); //doesn't work: $this-assertEquals( 'bar', $this->getView()->foo ); } }

  • Error while creating tests in Visual Studio

    When I try to generate a unit test for the following method (in a public static class) private static string[] GetFields(string line, char sep) { char[] totrim = { '"', ' ' }; return line.Split(sep).Select(col => col.Trim(totrim)).ToArray(); } The Tests output says: While trying to generate your tests, the following errors occurred: This method or property cannot be called within an event handler. It works if I make the function public - I've tried running Publicize.exe manually, it doesn't complain, but doesn't make any difference either.

  • MVC UI with Mock Controllers?

    - by Jaimal Chohan
    I'm working with Aspnet MVC 2 (R2) and at the same time playing about with the whole alt.net stack. One of this things I would like to be able todo is basically write my Views, and be able to interact with them without having to write the controller logic. E.g. I have a view that displays a list of orders and I can click on an order which redirects to another view where I can edit it, but I don't want to get into the nitty gritty of writing the code to actually get a list of orders, or update an existing ordes. I want to do so I can write UI tests in WaitN/AOT/Selenium without having to worry about whats happening underneath, and also It would help drive my controller logic on a need basis as opposed to guess work based of of the supplied screenshots How do you guys accomplish this atm? Can you provide links ot useful blog posts/tools/framework/articles with information on how to accomplish this p.s. I primarly use Rhino Mocks & NUnit but can happliy change to other tools if they support the above better.

  • How test that ASP.NET MVC route redirects to other site?

    - by Matt Lacey
    Due to a prinitng error in some promotional material I have a site that is receiving a lot of requests which should be for one site arriving at another. i.e. The valid sites are http://site1.com/abc & http://site2.com/def but people are being told to go to http://site1.com/def. I have control over site1 but not site2. site1 contains logic for checking that the first part of the route is valid in an actionfilter, like this: public override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); if ((!filterContext.ActionParameters.ContainsKey("id")) || (!manager.WhiteLabelExists(filterContext.ActionParameters["id"].ToString()))) { if (filterContext.ActionParameters["id"].ToString().ToLowerInvariant().Equals("def")) { filterContext.HttpContext.Response.Redirect("http://site2.com/def", true); } filterContext.Result = new ViewResult { ViewName = "NoWhiteLabel" }; filterContext.HttpContext.Response.Clear(); } } I'm not sure how to test the redirection to the other site though. I already have tests for redirecting to "NoWhiteLabel" using the MvcContrib Test Helpers, but these aren't able to handle (as far as I can see) this situation. How do I test the redirection to antoher site?

  • How to test an application for correct encoding (e.g. UTF-8)

    - by Olaf
    Encoding issues are among the one topic that have bitten me most often during development. Every platform insists on its own encoding, most likely some non-UTF-8 defaults are in the game. (I'm usually working on Linux, defaulting to UTF-8, my colleagues mostly work on german Windows, defaulting to ISO-8859-1 or some similar windows codepage) I believe, that UTF-8 is a suitable standard for developing an i18nable application. However, in my experience encoding bugs are usually discovered late (even though I'm located in Germany and we have some special characters that along with ISO-8859-1 provide some detectable differences). I believe that those developers with a completely non-ASCII character set (or those that know a language that uses such a character set) are getting a head start in providing test data. But there must be a way to ease this for the rest of us as well. What [technique|tool|incentive] are people here using? How do you get your co-developers to care for these issues? How do you test for compliance? Are those tests conducted manually or automatically? Adding one possible answer upfront: I've recently discovered fliptitle.com (they are providing an easy way to get weird characters written "u?op ?pisdn" *) and I'm planning on using them to provide easily verifiable UTF-8 character strings (as most of the characters used there are at some weird binary encoding position) but there surely must be more systematic tests, patterns or techniques for ensuring UTF-8 compatibility/usage. Note: Even though there's an accepted answer, I'd like to know of more techniques and patterns if there are some. Please add more answers if you have more ideas. And it has not been easy choosing only one answer for acceptance. I've chosen the regexp answer for the least expected angle to tackle the problem although there would be reasons to choose other answers as well. Too bad only one answer can be accepted. Thank you for your input. *) that's "upside down" written "upside down" for those that cannot see those characters due to font problems

  • XCode missing inline test results

    - by Vegar
    Everywhere there are pretty pictures of failing tests shown inline in the code editor, like in Peepcodes Objective-C for Rubyist screencast and in apples own technical documentation: When I build my test-target, all I get is a little red icon down in the right corner, stating something went wrong. When clicking on it, I get the Build Results, where I can start to hunt for test results. Do anyone have a clue on what´s wrong?
