  • Does new JUnit 4.8 @Category render test suites almost obsolete?

    - by grigory
    Given question 'How to run all tests belonging to a certain Category?' and the answer would the following approach be better for test organization? define master test suite that contains all tests (e.g. using ClasspathSuite) design sufficient set of JUnit categories (sufficient means that every desirable collection of sets is identifiable using one or more categories) define targeted test suites based on master test suite and set of categories For example: identify categories for speed (slow, fast), dependencies (mock, database, integration), function (), domain ( demand that each test is properly qualified (tagged) with relevant set of categories. create master test suite using ClasspathSuite (all tests found in classpath) create targeted suites by qualifying master test suite with categories, e.g. mock test suite, fast database test suite, slow integration for domain X test suite, etc. My question is more like soliciting approval rate for such approach vs. classic test suite approach. One unbeatable benefit is that every new test is immediately contained by relevant suites with no suite maintenance. One concern is proper categorization of each test.

  • using spring, hibernate and scala, is there a better way to load test data than dbunit?

    - by egervari
    Here are some things I really dislike about dbunit: 1) You cannot specify the exact ordering the inserts because dbunit likes to group your inserts by table name, and not by the order you define them in the XML file. This is a problem when you have records depending on other records in other tables, so you have to disable foreign key constraints during your tests... which actually sucks because these foreign key constraints will get fired in production while your tests won't be aware of them! 2) They seem hellbent on forcing you to use an xml namespace to define your xml... and I honestly can't be bothered to do this. I like the data.xml without any namespace. It works. But they are so hellbent on deprecating it. 3) Creating different xml files is hard on a per test basis, so it actually encourages creating data for your entire app. Unfortunately, this process is a little bloated too once the data grows in size and things get inter tangled. There has got to be a better way to split up your test data into chunks without having to copy/paste a lot of the test data across all of your tests. 4) Keeping track of id references in a big xml file is just impossible. If you have 130 domain classes, it just gets bewildering. This model simply does not scale. Is there something less bloated and better in the Spring/Hibernate space? db unit has worn out its welcome and I'm really looking for something better.

  • Second Unit Test Not Running

    - by TomJ
    I am having trouble getting my Method B test to run. The logic is fine, but when the unit tests are run, only Method A will run. If Method A and B are switched in terms of spots, only Method B will run. So clearly the code is wrong at some point. Do I need to call method B's test from inside method A in order to get both unit tests to run? I'm pretty new to C#, so forgive my basic question. using redacted; using Microsoft.VisualStudio.TestTools.UnitTesting; using System; namespace UnitTests { [TestClass()] public class ClassTest { public TestContext TestContext{get;set;} [TestMethod()] public void MethodATest() { the unit test } [TestMethod()] public void MethodBTest() { the unit test } } }

  • What's the best way to avoid try...catch...finally... in my unit tests?

    - by Bruce Li
    I'm writing many unit tests in VS 2010 with Microsoft Test. In each test class I have many test methods similar to below: [TestMethod] public void This_is_a_Test() { try { // do some test here // assert } catch (Exception ex) { // test failed, log error message in my log file and make the test fail } finally { // do some cleanup with different parameters } } When each test method looks like this I fell it's kind of ugly. But so far I haven't found a good solution to make my test code more clean, especially the cleanup code in the finally block. Could someone here give me some advices on this? Thanks in advance.

  • HTTP Proxy with monitor UI for local install

    - by zedoo
    Hi, I'm looking for an HTTP Proxy/GUI combination that should be installed locally on my Windows PC. The UI should display something similar to Firebugs "Network" tab, showing request/response headers and content as plaintext. It would be cool if I could attach requests to a sort of node for later comparison, similar to what you can do when using the Proxy that comes with JMeter.

  • How can I use the compile time constant __LINE__ in a string?

    - by John
    I can use __LINE__ as a method parameter just fine, but I would like an easy way to use it in a function that uses strings. For instance say I have this: 11 string myTest() 12 { 13 if(!testCondition) 14 return logError("testcondition failed"); 15 } And I want the result of the function to be: "myTest line 14: testcondition failed" How can I write logError? Does it have to be some monstrosity of a macro?

  • Is there a JUnit equivalent to NUnit's testcase attribute?

    - by Steph
    I've googled for JUnit test case, and it comes up with something that looks a lot more complicated to implement - where you have to create a new class that extends test case which you then call: public class MathTest extends TestCase { protected double fValue1; protected double fValue2; protected void setUp() { fValue1= 2.0; fValue2= 3.0; } } public void testAdd() { double result= fValue1 + fValue2; assertTrue(result == 5.0); } but what I want is something really simple, like the NUnit test cases [TestCase(1,2)] [TestCase(3,4)] public void testAdd(int fValue1, int fValue2) { double result= fValue1 + fValue2; assertIsTrue(result == 5.0); } Is there any way to do this in JUnit?

  • FRIEND_TEST in Google Test - possible circular dependency?

    - by Mihaela
    I am trying to figure out how FRIEND_TEST works in Google Tests. http://code.google.com/p/googletest/wiki/AdvancedGuide#Private_Class_Members I am looking at the following item, trying to implement it in my code: // foo.h #include "gtest/gtest_prod.h" // Defines FRIEND_TEST. class Foo { ... private: FRIEND_TEST(FooTest, BarReturnsZeroOnNull); int Bar(void* x); }; // foo_test.cc ... TEST(FooTest, BarReturnsZeroOnNull) { Foo foo; EXPECT_EQ(0, foo.Bar(NULL)); // Uses Foo's private member Bar(). } In the code above, the piece that I can't see, is that foo_test.cc must include foo.h, in order to have access to Foo and Bar(). [Perhaps it works differently for Google ? in my code, I must include it] That will result in circular dependency... Am I missing something ?

  • Unit test helper methods?

    - by Aly
    Hi, I have classes which prviously had massive methods so i subdivided the work of this method into 'helper' methods. These helper methods are declared private to enforce encapsulation - however I want to unit test the big public methods, is it good to unit test the helper methods too as if one of them fail the public method that calls it will also fail - but this way we can identify why it failed. Also in order to test these using a mock object I would need to change their visibility from private to protected, is this desirable?

  • Detecting use after free() on windows.

    - by The Rook
    I'm trying to detect "Use after free()" bugs, otherwise known as "Dangling pointers". I know Valgrind can be used to detect "Use after free" bugs on the *nix platform, but what about windows? What if I don't have the source? Is there a better program than Valgrind for detecting all dangling pointers in a program? A free and open source would be preferred , but I'll use a commercial solution if it will get the job done.

  • Django test client gets 301 redirection when accessing url

    - by Michal Klich
    I am writing unittests for django views. I have observed that one of my views returns redirection code 301, which is not expected. Here is my views.py mentioned earlier. def index(request): return render(request, 'index.html', {'form': QueryForm()}) def query(request): if request.is_ajax(): form = QueryForm(request.POST) return HttpResponse('valid') Below is urls.py. urlpatterns = patterns('', url(r'^$', 'core.views.index'), url(r'^query/$', 'core.views.query') ) And unittest that will fail. def so_test(self): response = self.client.post('/') self.assertEquals(response.status_code, 200) response = self.client.post('/query', {}) self.assertEquals(response.status_code, 200) My question is: why there is status 301 returned?

  • Is there a library available which easily can record and replay results of API calls?

    - by Billy ONeal
    I'm working on writing various things that call relatively complicated Win32 API functions. Here's an example: //Encapsulates calling NtQuerySystemInformation buffer management. WindowsApi::AutoArray NtDll::NtQuerySystemInformation( SystemInformationClass toGet ) const { AutoArray result; ULONG allocationSize = 1024; ULONG previousSize; NTSTATUS errorCheck; do { previousSize = allocationSize; result.Allocate(allocationSize); errorCheck = WinQuerySystemInformation(toGet, result.GetAs<void>(), allocationSize, &allocationSize); if (allocationSize <= previousSize) allocationSize = previousSize * 2; } while (errorCheck == 0xC0000004L); if (errorCheck != 0) { THROW_MANUAL_WINDOWS_ERROR(WinRtlNtStatusToDosError(errorCheck)); } return result; } //Client of the above. ProcessSnapshot::ProcessSnapshot() { using Dll::NtDll; NtDll ntdll; AutoArray systemInfoBuffer = ntdll.NtQuerySystemInformation( NtDll::SystemProcessInformation); BYTE * currentPtr = systemInfoBuffer.GetAs<BYTE>(); //Loop through the results, creating Process objects. SYSTEM_PROCESSES * asSysInfo; do { // Loop book keeping asSysInfo = reinterpret_cast<SYSTEM_PROCESSES *>(currentPtr); currentPtr += asSysInfo->NextEntryDelta; //Create the process for the current iteration and fill it with data. std::auto_ptr<ProcImpl> currentProc(ProcFactory( static_cast<unsigned __int32>(asSysInfo->ProcessId), this)); NormalProcess* nptr = dynamic_cast<NormalProcess*>(currentProc.get()); if (nptr) { nptr->SetProcessName(asSysInfo->ProcessName); } // Populate process threads for(ULONG idx = 0; idx < asSysInfo->ThreadCount; ++idx) { SYSTEM_THREADS& sysThread = asSysInfo->Threads[idx]; Thread thread( currentProc.get(), static_cast<unsigned __int32>(sysThread.ClientId.UniqueThread), sysThread.StartAddress); currentProc->AddThread(thread); } processes.push_back(currentProc); } while(asSysInfo->NextEntryDelta != 0); } My problem is in mocking out the NtDll::NtQuerySystemInformation method -- namely, that the data structure returned is complicated (Well, here it's actually relatively simple but it can be complicated), and writing a test which builds the data structure like the API call does can take 5-6 times as long as writing the code that uses the API. What I'd like to do is take a call to the API, and record it somehow, so that I can return that recorded value to the code under test without actually calling the API. The returned structures cannot simply be memcpy'd, because they often contain inner pointers (pointers to other locations in the same buffer). The library in question would need to check for these kinds of things, and be able to restore pointer values to a similar buffer upon replay. (i.e. check each pointer sized value if it could be interpreted as a pointer within the buffer, change that to an offset, and remember to change it back to a pointer on replay -- a false positive rate here is acceptable) Is there anything out there that does anything like this?

  • Automatic profiling visual studio 2008

    - by phil
    Is there a way to do automatic profiling in visual studio 2008? I know how the profiling works both from the command line and using the GUI in VS08. What I want to accomplish: After my nightly build I want to complete some profiling (instrumental) to see if some functions (will most likely always be the same) have changed in some negative way (or positive of course).

  • How to prevent swallowing exceptions caused by unset expectations for a mocked object?

    - by Schultz9999
    I am looking for a way to modify catch block depending on if it's executed during the unit test run or not. The purpose is basically to detect/setup mock expectations which are swallowed because catch doesn't rethrow. I am using MSTest. One obvious thing is using preprocessor but I don't think it works. Especially if to use DEBUG define. There should be an easy way to detect that, shouldn't it? I must have been looking for something wrong because I couldn't find much info on that. try {...} catch(Exception) { Log(...); #if DEBUG throw; #endif }

  • How to build a test suite 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 suite that combines them? Is it possible to enumerate the files that should be included in the test suite? Is it possible to auto include single test files into a test suite by subidr? Can I cascade (include other watir suites in watir suites)?

  • Test-driven Development: Writing tests for private / protected variables

    - by Chetan
    I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

  • Is there a Java unit-test framework that auto-tests getters and setters?

    - by Michael Easter
    There is a well-known debate in Java (and other communities, I'm sure) whether or not trivial getter/setter methods should be tested. Usually, this is with respect to code coverage. Let's agree that this is an open debate, and not try to answer it here. There have been several blog posts on using Java reflection to auto-test such methods. Does any framework (e.g. jUnit) provide such a feature? e.g. An annotation that says "this test T should auto-test all the getters/setters on class C, because I assert that they are standard". It seems to me that it would add value, and if it were configurable, the 'debate' would be left as an option to the user.

  • Is there a way to extract the message from a JavaScript dialog in Chrome?

    - by Samuel
    I’ve been working on an extension for automating tests in Chrome, and I came across an obscure issue with JavaScript dialogs. The message shown in the dialog can’t be readily retrieved/copied. I’ve used the GetWindowText and InternalGetWindowText functions, but they only return the title of the dialog and the text from the buttons, not the actual message itself. I even looked at programs that extract text from forms, but no luck. So does anyone know of a way to retrieve the text from these JavaScript dialogs in Chrome?
