  • NUnit vs. MsTest: NUnit wins for Unit Testing.

    People are still wondering what are the differences between the two most popular unit testing frameworks in the .NET world: the open source NUnit and the commercial MsTest). Heres a short list of what i remember instantly: Nunit contains a [TestCase] attribute that allows implementing parametrized tests. this does not exist in msTest MsTest's ExpectedException attribute has a bug where the expected message is never really asserted even if it's wrong - the test will pass. Nunit has an...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • How can this Ambient Context become null?

    - by Mark Seemann
    Can anyone help me explain how TimeProvider.Current can become null in the following class? public abstract class TimeProvider { private static TimeProvider current = DefaultTimeProvider.Instance; public static TimeProvider Current { get { return TimeProvider.current; } set { if (value == null) { throw new ArgumentNullException("value"); } TimeProvider.current = value; } } public abstract DateTime UtcNow { get; } public static void ResetToDefault() { TimeProvider.current = DefaultTimeProvider.Instance; } } Observations All unit tests that directly reference TimeProvider also invokes ResetToDefault() in their Fixture Teardown. There is no multithreaded code involved. Once in a while, one of the unit tests fail because TimeProvider.Current is null (NullReferenceException is thrown). This only happens when I run the entire suite, but not when I just run a single unit test, suggesting to me that there is some subtle test interdependence going on. It happens approximately once every five or six test runs. When a failure occurs, it seems to be occuring in the first executed tests that involves TimeProvider.Current. More than one test can fail, but only one fails in a given test run. FWIW, here's the DefaultTimeProvider class as well: public class DefaultTimeProvider : TimeProvider { private readonly static DefaultTimeProvider instance = new DefaultTimeProvider(); private DefaultTimeProvider() { } public override DateTime UtcNow { get { return DateTime.UtcNow; } } public static DefaultTimeProvider Instance { get { return DefaultTimeProvider.instance; } } } I suspect that there's some subtle interplay going on with static initialization where the runtime is actually allowed to access TimeProvider.Current before all static initialization has finished, but I can't quite put my finger on it. Any help is appreciated.

  • What did I do wrong here when trying to unit test a class that references a web service

    - by zachary
    So I had a class that referenced a class that referenced another class that called a web service. So I learn how to create an interface using partial classes. I inject the web service through the constructor. Then my unit test fails because I am newing up the actual web service in the second level of the class. So I end up modifying all three classes to pass the web service down through the constructor... was not happy :-( gave up.... what should I be doing in this case?

  • How can I display more info in an error message when using NUnit Assert in a loop?

    - by Ian
    Consider the following code: [Test] public void WidgetTest() { foreach (Widget widget in widgets) { Assert.AreEqual(0, widget.SomeValue); } } If one of the asserts fails, I will get a very unhelpful error message like the one below: 1) Test Failure : WidgetTest.TestSomeValue Expected: 0 But was: 1 at WidgetTest.TestSomeValue() So, the question is, how can I get NUnit to display more useful info, such as the name of the widget, or the iteration of the loop, etc? Even a line number would be more helpful, since this is run in automated manner and I'd like to be able to spot the failing assert without debugging into the code.

  • Is there a way to force JUnit to fail on ANY unchecked exception, even if swallowed

    - by Uri
    I am using JUnit to write some higher level tests for legacy code that does not have unit tests. Much of this code "swallows" a variety of unchecked exceptions like NullPointerExceptions (e.g., by just printing stack trace and returning null). Therefore the unit test can pass even through there is a cascade of disasters at various points in the lower level code. Is there any way to have a test fail on the first unchecked exception even if they are swallowed? The only alternative I can think of is to write a custom JUnit wrapper that redirects System.err and then analyzes the output for exceptions.

  • asp.net impersonation identity: Where does it come from?

    - by Rising Star
    Here's a simple question I've been stuck on for a while. When I set < identity impersonate=true > in my web.config so that asp.net impersonates the logged on user automatically (or the anonymous account if not using Windows Authentication), where does the identity that asp.net impersonates come from? This document: http://msdn.microsoft.com/en-us/library/ff649264.aspx shows three places you can retrieve information about the logged on user: Httpcontext.Current.user System.Threading.Thread.Current System.Security.Principal.WindowsIdentity.GetCurrent It seems that none of these locations consistently match the identity that gets impersonated when I set < identity impersonate=true > in web.config. I would like to know where the impersonated identity comes from.

  • Why is my rspec test failing?

    - by Justin Meltzer
    Here's the test: describe "admin attribute" do before(:each) do @user = User.create!(@attr) end it "should respond to admin" do @user.should respond_to(:admin) end it "should not be an admin by default" do @user.should_not be_admin end it "should be convertible to an admin" do @user.toggle!(:admin) @user.should be_admin end end Here's the error: 1) User password encryption admin attribute should respond to admin Failure/Error: @user = User.create!(@attr) ActiveRecord::RecordInvalid: Validation failed: Email has already been taken # ./spec/models/user_spec.rb:128 I'm thinking the error might be somewhere in my data populator code: require 'faker' namespace :db do desc "Fill database with sample data" task :populate => :environment do Rake::Task['db:reset'].invoke admin = User.create!(:name => "Example User", :email => "[email protected]", :password => "foobar", :password_confirmation => "foobar") admin.toggle!(:admin) 99.times do |n| name = Faker::Name.name email = "example-#{n+1}@railstutorial.org" password = "password" User.create!(:name => name, :email => email, :password => password, :password_confirmation => password) end end end Please let me know if I should reproduce any more of my code.

  • Organizing test hierarchy in clojure project

    - by Sergey
    There are two directories in a clojure project - src/ and test/. There's a file my_methods.clj in the src/calc/ directory which starts with (ns calc.my_methods...). I want to create a test file for it in test directory - test/my_methods-test.clj (ns test.my_methods-test (:require [calc.my_methods]) (:use clojure.test)) In the $CLASSPATH there are both project root directory and src/ directory. But the exception is still "Could not locate calc/my_methods__init.class or calc/my_methods.clj on classpath". What is the problem with requiring it in the test file? echo $CLASSPATH gives this: ~/project:~/project/src

  • Global.asax for Unit Tests?

    - by AngryHacker
    In my MSTest UnitTest project, before running any tests, I need to execute some commands. Is there a feature, kind of like Global.asax is for web based projects, that will let me kick off something before any tests run?

  • Why is using a Non-Random IV with CBC Mode a vulnerability?

    - by The Rook
    I understand the purpose of an IV. Specifically in CBC mode this insures that the first block of of 2 messages encrypted with the same key will never be identical. But why is it a vulnerability if the IV's are sequential? According to CWE-329 NON-Random IV's allow for the possibility of a dictionary attack. I know that in practice protocols like WEP make no effort to hide the IV. If the attacker has the IV and a cipher text message then this opens the door for a dictionary attack against the key. I don't see how a random iv changes this. (I know the attacks against wep are more complex than this.) What security advantage does a randomized iv have? Is this still a problem with an "Ideal Block Cipher"? (A perfectly secure block cipher with no possible weaknesses.)

  • Application Role and access second database

    - by lszk
    I have written a script to create an audit trails to my database in a second one db. So far I had no problems during tests on my dev machine from SQL Server Management Studio. Problems started to occurs when I first tried to test my triggers from my application by modyfing data in it. Using profiler I found out, that my audit trails db is not visible in sys.databases, so here lies the problem. The application using an Application Role, so as I found on MSDN, that's why I can't get access to other db on the server. I'm not a DBA. I have no experience with properly settings the security stuff, so please guide me, how can I set the setting for guest account (according to MSDN) to get access to this db? I need to have a record for this database in sys.databases and I need to be able to insert data in this database in all tables. No select, update or delete I need.

  • In TDD, should tests be written by the person who implemented the feature under test?

    - by martin
    We run a project in which we want to solve with test driven development. I thought about some questions that came up when initiating the project. One question was: Who should write the unit-test for a feature? Should the unit-test be written by the feature-implementing programmer? Or should the unit test be written by another programmer, who defines what a method should do and the feature-implementing programmer implements the method until the tests runs? If I understand the concept of TDD in the right way, the feature-implementing programmer has to write the test by himself, because TDD is procedure with mini-iterations. So it would be too complex to have the tests written by another programmer? What would you say? Should the tests in TDD be written by the programmer himself or should another programmer write the tests that describes what a method can do?

  • Best practices to test protected methods with PHPUnit

    - by GrGr
    Hello, I found the discussion on Do you test private method informative. I have decided, that in some classes, I want to have protected methods, but test them. Some of these methods are static and short. Because most of the public methods make use of them, I will probably be able to safely remove the tests later. But for starting with a TDD approach and avoid debugging, I really want to test them. I thought of the following: Method Object as adviced in an answer seems to be overkill for this. Start with public methods and when code coverage is given by higher level tests, turn them protected and remove the tests. Inherit a class with a testable interface making protected methods public Which is best practice? Is there anything else? It seems, that JUnit automatically changes protected methods to be public, but I did not have a deeper look at it. PHP does not allow this via reflection.

  • How secure is encryption?

    - by Stomped
    Let me preface this by saying I know nothing about encryption. I understand the basic concept of public key / private key encryption but I don't how easily it can be broken, if at all. If one were to believe the movies, encrypted data can be broken by a teenager with a decent computer in a few hours. I have a client who wants credit card information sent via email - encrypted of course, but I'm still not feeling terribly good about the idea. I feel it would be safer to store the info on the VPS, but even then its an unmanaged server and there's nobody watching it who knows much about security. So can anyone tell me if there's a safe way to store and/or send this data out? Thanks

  • Visual studio 2008 unit test keeps failing

    - by Gerbrand
    I've create a method that calculates the harmonic mean based on a list of doubles. But when I'm running the test it keeps failing even thou the output result are the same. My harmonic mean method: public static double GetHarmonicMean(List<double> parameters) { var cumReciprocal = 0.0d; var countN = parameters.Count; foreach( var param in parameters) { cumReciprocal += 1.0d/param; } return 1.0d/(cumReciprocal/countN); } My test method: [TestMethod()] public void GetHarmonicMeanTest() { var parameters = new List<double> { 1.5d, 2.3d, 2.9d, 1.9d, 5.6d }; const double expected = 2.32432293165495; var actual = OwnFunctions.GetHarmonicMean(parameters); Assert.AreEqual(expected, actual); } After running the test the following message is showing: Assert.AreEqual failed. Expected:<2.32432293165495. Actual:<2.32432293165495. For me that are both the same values. Can somebody explain this? Or am I doing something wrong?

  • Can Django flush its database(s) between every unit test

    - by mikem
    Django (1.2 beta) will reset the database(s) between every test that runs, meaning each test runs on an empty DB. However, the database(s) are not flushed. One of the effects of flushing the database is the auto_increment counters are reset. Consider a test which pulls data out of the database by primary key: class ChangeLogTest(django.test.TestCase): def test_one(self): do_something_which_creates_two_log_entries() log = LogEntry.objects.get(id=1) assert_log_entry_correct(log) log = LogEntry.objects.get(id=2) assert_log_entry_correct(log) This will pass because only two log entries were ever created. However, if another test is added to ChangeLogTest and it happens to run before test_one, the primary keys of the log entries are no longer 1 and 2, they might be 2 and 3. Now test_one fails. This is actually a two part question: Is it possible to force ./manage.py test to flush the database between each test case? Since Django doesn't flush the DB between each test by default, maybe there is a good reason. Does anyone know?

  • Images with unknown content: Dangerous for a browser?

    - by chris_l
    Let's say I allow users to link to any images they like. The link would be checked for syntactical correctness, escaping etc., and then inserted in an <img src="..."/> tag. Are there any known security vulnerabilities, e.g. by someone linking to "evil.example.com/evil.jpg", and evil.jpg contains some code that will be executed due to a browser bug or something like that? (Let's ignore CSRF attacks - it must suffice that I will only allow URLs with typical image file suffixes.)

  • Stop MSVC++ debug errors from blocking the current process?

    - by Mike Arthur
    Any failed ASSERT statements on Windows cause the below debug message to appear and freeze the applications execution. I realise this is expected behaviour but it is running periodically on a headless machine so prevent the unit tests from failing, instead waiting on user input indefinitely. Is there s a registry key or compiler flag I can use to prevent this message box from requesting user input whilst still allowing the test to fail under ASSERT? Basically, I want to do this without modifying any code, just changing compiler or Windows options. Thanks!

  • Managing test data for Junit tests.

    - by nobody
    Hi, We are facing one problem in managing test data(xmls which is used to create mock objects). The data which we have currently has been evolved over a long period of time. Each time we add a new functionality or test case we add new data to test that functionality. Now, the problem is when the business requirement changes the format( like length or format of a variable) or any change which the test data doesn't support , we need to change the entire test data which is 100s of MBs in size. Could anyone suggest a better method or process to overcome this problem? Any suggestion would be appreciated.

  • Is it a bad idea to create tests that rely on each other within a test fixture?

    - by nbolton
    For example: // NUnit-like pseudo code (within a TestFixture) Ctor() { m_globalVar = getFoo(); } [Test] Create() { a(m_globalVar) } [Test] Delete() { // depends on Create being run b(m_globalVar) } … or… // NUnit-like pseudo code (within a TestFixture) [Test] CreateAndDelete() { Foo foo = getFoo(); a(foo); // depends on Create being run b(foo); } … I’m going with the later, and assuming that the answer to my question is: No, at least not with NUnit, because according to the NUnit manual: The constructor should not have any side effects, since NUnit may construct the class multiple times in the course of a session. ... also, can I assume it's bad practice in general? Since tests can usually be run separately. So the result of Create may never be cleaned up by Delete.

  • unittest in python: ignore an import from the code I want to test

    - by vaidab
    I have a python program that imports pythoncom (and uses pythoncom.CoCreateInstance from it). I want to create a unittest for the program logic without it importing pythoncom (so I can run the test on Linux as well). What options are there? Can I do it without modifying the system under test? What I found so far: sys.modules["pythoncom"] = "test" import module_that_imports_pythoncom My problem with it is if I have: from pythoncom.something import something I'll get: ImportError: No module named something.something And sys.modules["something.something"] or sys.modules["pythoncom.something.something"] doesn't work. Any ideas?
