  • Rails 2.3.5 table populated by fixtures at end of test run rather than at start

    - by rlandster
    I start with a test database containing the schema but with no data in the tables. I run a test like so cd test/ ruby unit/directive_test.rb I get failures indicating that the code found no data in the data tables. However, I look at the tables after running that test and the data is now in the the table. In fact, if I immediately run the test again I get no failures. So it appears that the fixture is being loaded into the table too late for one of my modules to find it. When are the fixtures loaded? After or before the app/model/*.rb files are executed? If it is after the models are executed is there a way to delay the loading? This issue is also relevant when running rake test:units since that task clears the test data after it finished.

  • Default Values Specflow Step Definitions

    - by Gavin Osborn
    I'm starting out in the world of SpecFlow and I have come across my first problem. In terms of keeping my code DRY I'd like to do the following: Have two scenarios: Given I am on a product page And myfield equals todays date Then... Given I am on a product page And myfield equals todays date plus 4 days Then... I was hoping to use the following Step Definition to cover both variants of my And clause: [Given(@"myfield equals todays date(?: (plus|minus) (\d+) days)?")] public void MyfieldEqualsTodaysDate(string direction, int? days) { //do stuff } However I keep getting exceptions when SpecFlow tries to parse the int? param. I've checked the regular expression and it definitely parses the scenario as expected. I'm aware that I could so something as crude as method overloading etc, I was just wondering if SpecFlow supported the idea of default parameter values, or indeed another way to achieve the same effect. Many Thanks

  • 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.

  • 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.

  • Argument constraints in RhinoMock methods

    - by Khash
    I am mocking a repository that should have 1 entity in it for the test scenario. The repository has to return this entity based on a known id and return nothing when other ids are passed in. I have tried doing something like this: _myRepository.Expect(item => item.Find(knownId)).Return(knownEntity); _myRepository.Expect(item => item.Find(Arg<Guid>.Is.Anything)).Return(null); It seems however the second line is overriding the first and the repository always returns null. I don't want to mock all the different possible IDs asked (they could go up to hundreds) when the test scenario is only concerned with the value of one Id.

  • How to unit tests functions which return results asyncronously in XCode?

    - by DevDevDev
    I have something like - (void)getData:(SomeParameter*)param { // Remotely call out for data returned asynchronously // returns data via a delegate method } - (void)handleDataDelegateMethod:(NSData*)data { // Handle returned data } I want to write a unit test for this, how can I do something better than NSData* returnedData = nil; - (void)handleDataDelegateMethod:(NSData*)data { returnedData = data; } - (void)test { [obj getData:param]; while (!returnedData) { [NSThread sleep:1]; } // Make tests on returnedData }

  • mocking static method call to c# library class

    - by Joe
    This seems like an easy enough issue but I can't seem to find the keywords to effect my searches. I'm trying to unit test by mocking out all objects within this method call. I am able to do so to all of my own creations except for this one: public void MyFunc(MyVarClass myVar) { Image picture; ... picture = Image.FromStream(new MemoryStream(myVar.ImageStream)); ... } FromStream is a static call from the Image class (part of c#). So how can I refactor my code to mock this out because I really don't want to provide a image stream to the unit test.

  • Python: How to run unittest.main() for all source files in a subdirectory?

    - by Pete
    I am developing a Python module with several source files, each with its own test class derived from unittest right in the source. Consider the directory structure: dirFoo\ test.py dirBar\ __init__.py Foo.py Bar.py To test either Foo.py or Bar.py, I would add this at the end of the Foo.py and Bar.py source files: if __name__ == "__main__": unittest.main() And run Python on either source, i.e. $ python Foo.py ........... ---------------------------------------------------------------------- Ran 11 tests in 2.314s OK Ideally, I would have "test.py" automagically search dirBar for any unittest derived classes and make one call to "unittest.main()". What's the best way to do this in practice? I tried using Python to call execfile for every *.py file in dirBar, which runs once for the first .py file found & exits the calling test.py, plus then I have to duplicate my code by adding unittest.main() in every source file--which violates DRY principles.

  • 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 ?

  • Element not found blocks execution in Selenium

    - by Mariano
    In my test, I try to verify if certain text exists (after an action) using find_element_by_xpath. If I use the right expression and my test pass, the routine ends correctly in no time. However if I try a wrong text (meaning that the test will fail) it hangs forever and I have to kill the script otherwise it does not end. Here is my test (the expression Thx user, client or password you entered is incorrect does not exist in the system, no matter what the user does): # -*- coding: utf-8 -*- import gettext import unittest from selenium import webdriver class TestWrongLogin(unittest.TestCase): def setUp(self): self.driver = webdriver.Firefox() self.driver.get("http://10.23.1.104:8888/") # let's check the language try: self.lang = self.driver.execute_script("return navigator.language;") self.lang = self.lang("-")[0] except: self.lang = "en" language = gettext.translation('app', '/app/locale', [self.lang], fallback=True) language.install() self._ = gettext.gettext def tearDown(self): self.driver.quit() def test_wrong_client(self): # test wrong client inputElement = self.driver.find_element_by_name("login") inputElement.send_keys("root") inputElement = self.driver.find_element_by_name("client") inputElement.send_keys("Unleash") inputElement = self.driver.find_element_by_name("password") inputElement.send_keys("qwerty") self.driver.find_element_by_name("form.submitted").click() # wait for the db answer self.driver.implicitly_wait(10) ret = self.driver.find_element_by_xpath( "//*[contains(.,'{0}')]".\ format(self._(u"Thx user, client or password you entered is incorrect"))) self.assertTrue(isinstance(ret, webdriver.remote.webelement.WebElement)) if __name__ == '__main__': unittest.main() Why does it do that and how can I prevent it?

  • 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?

    Hi, I intend to perform some automated integration tests. This requires the db to be put back into a 'clean state'. Is this the fastest/best way to do this: var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly("Bla"); new SchemaExport(cfg).Execute(false, true, false); Thanks. Christian

  • 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.

  • 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.

  • 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?

  • 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 }
