  • maven test cannot load cross-module resources/properties ?

    - by smallufo
    I have a maven mantained project with some modules . One module contains one XML file and one parsing class. Second module depends on the first module. There is a class that calls the parsing class in the first module , but maven seems cannot test the class in the second module. Maven test reports : java.lang.NullPointerException at java.util.Properties.loadFromXML(Properties.java:851) at foo.firstModule.Parser.<init>(Parser.java:92) at foo.secondModule.Program.<init>(Program.java:84) In "Parser.java" (in the first module) , it uses Properties and InputStream to read/parse an XML file : InputStream xmlStream = getClass().getResourceAsStream("Data.xml"); Properties properties = new Properties(); properties.loadFromXML(xmlStream); The "data.xml" is located in first module's resources/foo/firstModule directory , and it tests OK in the first module. It seems when testing the second module , maven cannot correctly load the Data.xml in the first module . I thought I can solve the problem by using maven-dependency-plugin:unpack to solve it . In the second module's POM file , I add these snippets : <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.1</version> <executions> <execution> <id>data-copying</id> <phase>test-compile</phase> <goals> <goal>unpack</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>foo</groupId> <artifactId>firstModule</artifactId> <type>jar</type> <includes>foo/firstModule/Data.xml</includes> <outputDirectory>${project.build.directory}/classes</outputDirectory> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> In this POM file , I try to unpack the first module , and copy the Data.xml to classes/foo/firstModule/ directory , and then run tests. And indeed , it is copied to the right directory , I can find the "Data.xml" file in "target/classes/foo/firstModule" directory. But maven test still complains it cannot read the File (Properties.loadFromXML() throws NPE). I don't know how to solve this problem. I tried other output directory , such as ${project.build.directory}/resources , and ${project.build.directory}/test-classes , but all in vain... Any advices now ? Thanks in advanced. Environments : Maven 2.2.1 , eclipse , m2eclipse

  • Can I use Visual Studio's testing facilities in native code?

    - by Billy ONeal
    Is it possible to use Visual Studio's testing system with native code? I have no objection to recompiling the code itself under C++/CLI if it's possible the code can be recompiled without changes -- but the production code shipped has to be native code. The Premium Edition comes with code coverage support which I might be able to get cheaply from my University -- but I can get the Professional Edition for free from DreamSpark -- and that's the only thing I can see that I'd use. (But I'd use it a LOT)

  • What is wrong with accessing DBI directly?

    - by canavanin
    Hi everyone! I'm currently reading Effective Perl Programming (2nd edition). I have come across a piece of code which was described as being poorly written, but I don't yet understand what's so bad about it, or how it should be improved. It would be great if someone could explain the matter to me. Here's the code in question: sub sum_values_per_key { my ( $class, $dsn, $user, $password, $parameters ) = @_; my %results; my $dbh = DBI->connect( $dsn, $user, $password, $parameters ); my $sth = $dbh->prepare( 'select key, calculate(value) from my_table'); $sth->execute(); # ... fill %results ... $sth->finish(); $dbh->disconnect(); return \%results; } The example comes from the chapter on testing your code (p. 324/325). The sentence that has left me wondering about how to improve the code is the following: Since the code was poorly written and accesses DBI directly, you'll have to create a fake DBI object to stand in for the real thing. I have probably not understood a lot of what the book has so far been trying to teach me, or I have skipped the section relevant for understanding what's bad practice about the above code... Well, thanks in advance for your help!

  • asp.net mvc How to test controllers correctly

    - by Simon G
    Hi, I'm having difficulty testing controllers. Original my controller for testing looked something like this: SomethingController CreateSomethingController() { var somethingData = FakeSomethingData.CreateFakeData(); var fakeRepository = FakeRepository.Create(); var controller = new SomethingController(fakeRepository); return controller; } This works fine for the majority of testing until I got the Request.IsAjaxRequest() part of code. So then I had to mock up the HttpContext and HttpRequestBase. So my code then changed to look like: public class FakeHttpContext : HttpContextBase { bool _isAjaxRequest; public FakeHttpContext( bool isAjaxRequest = false ) { _isAjaxRequest = isAjaxRequest; } public override HttpRequestBase Request { get { string ajaxRequestHeader = ""; if ( _isAjaxRequest ) ajaxRequestHeader = "XMLHttpRequest"; var request = new Mock<HttpRequestBase>(); request.SetupGet( x => x.Headers ).Returns( new WebHeaderCollection { {"X-Requested-With", ajaxRequestHeader} } ); request.SetupGet( x => x["X-Requested-With"] ).Returns( ajaxRequestHeader ); return request.Object; } } private IPrincipal _user; public override IPrincipal User { get { if ( _user == null ) { _user = new FakePrincipal(); } return _user; } set { _user = value; } } } SomethingController CreateSomethingController() { var somethingData = FakeSomethingData.CreateFakeData(); var fakeRepository = FakeRepository.Create(); var controller = new SomethingController(fakeRepository); ControllerContext controllerContext = new ControllerContext( new FakeHttpContext( isAjaxRequest ), new RouteData(), controller ); controller.ControllerContext = controllerContext; return controller; } Now its got to that stage in my controller where I call Url.Route and Url is null. So it looks like I need to start mocking up routes for my controller. I seem to be spending more time googling on how to fake/mock objects and then debugging to make sure my fakes are correct than actual writing the test code. Is there an easier way in to test a controller? I've looked at the TestControllerBuilder from MvcContrib which helps with some of the issues but doesn't seem to do everything. Is there anything else available that will do the job and will let me concentrate on writing the tests rather than writing mocks? Thanks

  • How to assert/unit-test servers JSON response?

    - by shazax
    My current project uses JSON as data interchange format. Both Front-end and Back-end team agree upon a JSON structure before start integrating a service. At times due to un-notified changes in JSON structure by back-end team; it breaks the front-end code. Is there any external library that we could use to compare a mock JSON (fixture) with servers JSON response. Basically it should assert the whole JSON object and should throw an error if there is any violation in servers JSON format. Additional info: App is built on JQuery consuming REST JSON services.

  • custom attribute changes in .NET 4

    - by Sarah Vessels
    I recently upgraded a C# project from .NET 3.5 to .NET 4. I have a method that extracts all MSTest test methods from a given list of MethodBase instances. Its body looks like this: return null == methods || methods.Count() == 0 ? null : from method in methods let testAttribute = Attribute.GetCustomAttribute(method, typeof(TestMethodAttribute)) where null != testAttribute select method; This worked in .NET 3.5, but since upgrading my projects to .NET 4, this code always returns an empty list, even when given a list of methods containing a method that is marked with [TestMethod]. Did something change with custom attributes in .NET 4? Debugging, I found that the results of GetCustomAttributesData() on the test method gives a list of two CustomAttributeData which are described in Visual Studio 2010's 'Locals' window as: Microsoft.VisualStudio.TestTools.UnitTesting.DeploymentItemAttribute("myDLL.dll") Microsoft.VisualStudio.TestTools.UnitTesting.TestMethodAttribute() -- this is what I'm looking for When I call GetType() on that second CustomAttributeData instance, however, I get {Name = "CustomAttributeData" FullName = "System.Reflection.CustomAttributeData"} System.Type {System.RuntimeType}. How can I get TestMethodAttribute out of the CustomAttributeData, so that I can extract test methods from a list of MethodBases?

  • How to build a test group in watir?

    - by karlthorwald
    I have some single watir.rb scripts that use IE and are written in a standard watir way. How do I create a test group that combines them? I want all of them be executed by executing the main script. Is it possible to auto include single test files into a test group by subidr? Is it possible to enumerate the files that should be included in the test group? Can I cascade (include other watir test groups in a watir test group)?

  • In an Android test, how to check that a View is shown?

    - by Jan Zankowski
    Hello, I'm writing a UI test case (using ActivityUnitTestCase) and would like to check if at a given time a View subclass is visible to the user. I've found the View#isShown() method, which claims to do exactly this - checking the visibility field of this element and all its parents - but somehow it always returns "false" for all the elements. I'll be grateful for some help. If it makes it easier, I can paste some code. Also, I found ViewAsserts#assertOnScreen(View origin, View view) but it doesn't seem to do the right thing either - always returns true. Am I perhaps calling it wrong: assertOnScreen(viewImTesting.getRootView(), viewImTesting)? Thanks, Jan

  • Moving a unit precisely along a path in x,y coordinates

    - by Adam Eberbach
    I am playing around with a strategy game where squads move around a map. Each turn a certain amount of movement is allocated to a squad and if the squad has a destination the points are applied each turn until the destination is reached. Actual distance is used so if a squad moves one position in the x or y direction it uses one point, but moving diagonally takes ~1.4 points. The squad maintains actual position as float which is then rounded to allow drawing the position on the map. The path is described by touching the squad and dragging to the end position then lifting the pen or finger. (I'm doing this on an iPhone now but Android/Qt/Windows Mobile would work the same) As the pointer moves x, y points are recorded so that the squad gains a list of intermediate destinations on the way to the final destination. I'm finding that the destinations are not evenly spaced but can be further apart depending on the speed of the pointer movement. Following the path is important because obstacles or terrain matter in this game. I'm not trying to remake Flight Control but that's a similar mechanic. Here's what I've been doing, but it just seems too complicated (pseudocode): getDestination() { - self.nextDestination = remove_from_array(destinations) - self.gradient = delta y to destination / delta x to destination - self.angle = atan(self.gradient) - self.cosAngle = cos(self.angle) - self.sinAngle = sin(self.angle) } move() { - get movement allocation for this turn - if self.nextDestination not valid - - getNextDestination() - while(nextDestination valid) && (movement allocation remains) { - - find xStep and yStep using movement allocation and sinAngle/cosAngle calculated for current self.nextDestination - - if current position + xStep crosses the destination - - - find x movement remaining after self.nextDestination reached - - - calculate remaining direct path movement allocation (xStep remaining / cosAngle) - - - make self.position equal to self.nextDestination - - else - - - apply xStep and yStep to current position - } - round squad's float coordinates to integer screen coordinates - draw squad image on map } That's simplified of course, stuff like sign needs to be tweaked to ensure movement is in the right direction. If trig is the best way to do it then lookup tables can be used or maybe it doesn't matter on modern devices like it used to. Suggestions for a better way to do it? an update - iPhone has zero issues with trig and tracking tens of positions and tracks implemented as described above and it draws in floats anyway. The Bresenham method is more efficient, trig is more precise. If I was to use integer Bresenham I would want to multiply by ten or so to maintain a little more positional accuracy to benefit collisions/terrain detection.

  • How to get started with testing(jMock)

    - by London
    Hello, I'm trying to learn how to write tests. I'm also learning Java, I was told I should learn/use/practice jMock, I've found some articles online that help to certain extend like : http://www.theserverside.com/news/1365050/Using-JMock-in-Test-Driven-Development http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock And most articles I found was about test driven development, write tests first then write code to make the test pass. I'm not looking for that at the moment, I'm trying to write tests for already existing code with jMock. The official documentation is vague to say the least and just too hard for me. Does anybody have better way to learn this. Good books/links/tutorials would help me a lot. thank you EDIT - more concrete question : http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock - from this article Tried this to mock this simple class : import java.util.Map; public class Cache { private Map<Integer, String> underlyingStorage; public Cache(Map<Integer, String> underlyingStorage) { this.underlyingStorage = underlyingStorage; } public String get(int key) { return underlyingStorage.get(key); } public void add(int key, String value) { underlyingStorage.put(key, value); } public void remove(int key) { underlyingStorage.remove(key); } public int size() { return underlyingStorage.size(); } public void clear() { underlyingStorage.clear(); } } Here is how I tried to create a test/mock : public class CacheTest extends TestCase { private Mockery context; private Map mockMap; private Cache cache; @Override @Before public void setUp() { context = new Mockery() { { setImposteriser(ClassImposteriser.INSTANCE); } }; mockMap = context.mock(Map.class); cache = new Cache(mockMap); } public void testCache() { context.checking(new Expectations() {{ atLeast(1).of(mockMap).size(); will(returnValue(int.class)); }}); } } It passes the test and basically does nothing, what I wanted is to create a map and check its size, and you know work some variations try to get a grip on this. Understand better trough examples, what else could I test here or any other exercises would help me a lot. tnx

  • Rails testing authlogic

    - by pepernik
    I just started using tests. I try to test the login like this require 'test_helper' class UserFlowsTest < ActionController::IntegrationTest fixtures :all # Replace this with your real tests. test "login and browse" do https! get "/users/new" assert_response :success post "/user_sessions", :email => '[email protected]', :password => 'aaaa' follow_redirect! assert_equal root_path, path end end I use authlogic gem in my rails app. What is wrong with this test? It breaks at 'follow_redirect!' saying it is not a redirection but login through a browser works. Thx!

  • Good tool to test WCF service (not SOAP/HTTP webservice)

    - by Kangkan
    I recently found SOAPUI and discovered that it is just a great tool for testing any SOAP/HTTP service. Conventionally, we have been developing our own driver to test our services (WCF based netTCP binding) so far. But with SOAPUI experience, I am really looking for some such tool that can be used with such ease with built-in facilities for load testing, functional testing etc. The other thought in my mind is that for services that I wish to deploy with netTCP can be first tested using a HTTP binding using SOAPUI. Once found suitable, the binding can be changed for the intended one. I shall like the views from all the experts here. Thanks.

  • Are there any open source SimpleTest Test Cases that test PHP SPL interfaces

    - by JW
    I have quite a few objects in my system that implement the PHP SPL Iterator interface. As I write them I also write tests. I know that writing tests is generally NOT a cut 'n paste job. But, when it comes to testing classes that implement Standard PHP Library interfaces, surely it makes sense to have a few script snippets that can be borrowed and dropped in to a Test class - purely to test that particular interface. It seems sensible to have these publicly available. So, I was wondering if you knew of any?

  • Moq.Mock<T> - how to setup a method that takes an expression

    - by Paul
    I am Mocking my repository interface and am not sure how to setup a method that takes an expression and returns an object? I am using Moq and NUnit Interface: public interface IReadOnlyRepository : IDisposable { IQueryable<T> All<T>() where T : class; T Single<T>(Expression<Func<T, bool>> expression) where T : class; } Test with IQueryable already setup, but don't know how to setup the T Single: private Moq.Mock<IReadOnlyRepository> _mockRepos; private AdminController _controller; [SetUp] public void SetUp() { var allPages = new List<Page>(); for (var i = 0; i < 10; i++) { allPages.Add(new Page { Id = i, Title = "Page Title " + i, Slug = "Page-Title-" + i, Content = "Page " + i + " on page content." }); } _mockRepos = new Moq.Mock<IReadOnlyRepository>(); _mockRepos.Setup(x => x.All<Page>()).Returns(allPages.AsQueryable()); //Not sure what to do here??? _mockRepos.Setup(x => x.Single<Page>() //---- _controller = new AdminController(_mockRepos.Object); }

  • Need help with writing test

    - by London
    I'm trying to write a test for this class its called Receiver : public void get(People person) { if(null != person) { LOG.info("Person with ID " + person.getId() + " received"); processor.process(person); }else{ LOG.info("Person not received abort!"); } } Here is the test : @Test public void testReceivePerson(){ context.checking(new Expectations() {{ receiver.get(person); atLeast(1).of(person).getId(); will(returnValue(String.class)); }}); } Note: receiver is the instance of Receiver class(real not mock), processor is the instance of Processor class(real not mock) which processes the person(mock object of People class). GetId is a String not int method that is not mistake. Test fails : unexpected invocation of person.getId() I'm using jMock any help would be appreciated. As I understood when I call this get method to execute it properly I need to mock person.getId() , and I've been sniping around in circles for a while now any help would be appreciated.

  • How to run only the latest/a given test using Rspec?

    - by marcgg
    Let's say I have a big spec file with 20 tests because I'm testing a large model and I had no other way of doing it : describe Blah it "should do X" do ... end it "should do Y" do ... end ... it "should do Z" do ... end end Running a single file is faster than running the whole test suite, but it's still pretty long. Is there a way to run the last one (ie the one at the end of the file, here "should do Z")? If this is not possible, is there a way to specify which test I want to run in my file ?

  • Test MVC using moq

    - by Raminder
    I am new to moq and I was trying to test a controller (MVC) behaviour that when the view raises a certain event, controller calls a certain function on model, here are the classes - public class Model { public void CalculateAverage() { ... } ... } public class View { public event EventHandler CalculateAverage; private void RaiseCalculateAverage() { if (CalculateAverage != null) { CalculateAverage(this, EventArgs.Empty); } } ... } public class Controller { private Model model; private View view; public Controller(Model model, View view) { this.model = model this.view = view; view.CalculaeAverage += view_CalculateAverage; } priavate void view_CalculateAverage(object sender, EventArgs args) { model.CalculateAverage(); } } and the test - [Test] public void ModelCalculateAverageCalled() { Mock<Model> modelMock = new Mock<Model>(); Mock<View> viewMock = new Mock<View>(); Controller controller = new Controller(modelMock.Object, viewMock.Object); viewMock.Raise(x => x.CalculateAverage += null, new EventArgs.Empty); modelMock.Verify(x => x.CalculateAverage()); //never comes here, test fails in above line and exits Assert.True(true); } The issue is that the test is failing in the second last line with "Invocation was not performed on the mock: x = x.CalculateAverage()". Another thing I noticed is that the test terminates on this second last line and the last line is never executed. Am I doing everything correct?
