As far as I am concerned, the attributes that feed the test are NUnit code and should be invariant. CultureInfo.CurrentCulture = new CultureInfo("de-DE", false) (That is why NUnit/xUnit/MSTest all ask you to install a test adapter NuGet package to your unit testing projects). When the time comes to think about the next release, I want to be 100% focused on that. Utc)); Making the clock a service. I'd suggest the culture used is either invariant or explicitly set by the user - I don't think it's a good idea to bring CurrentCulture into this at all. You can specify the date as a constant string in the TestCase attribute and then specify the type as DateTime in the method signature. But the more I think about it, the less obvious the decision between the two seems. Users passing in strings and us converting them to dates is a convenience that NUnit provides because the values in test case attributes must be const. I can understand the To fully "fix" this, the TestCase and Values attributes would have to be aware of the test property that SetCulture attribute. NUnit uses the parameters to differentiate individual test cases. . but I can see the method which converts the TestCaseAttribute parameters is also passed the parent suite Test. Is this not something of an implementation detail? Thank everyone for quick response. Przepis jest następujący – Atrybutowi metody TestCase przypisujemy kolejno wartości, które są odwzorowaniem parametrów naszego testu. Copyright © 2020 Ivan Krivyakov. Which is better during test creation- actually setting the thread's culture, or passing in the correct CultureInfo to DateTime.Parse? Please note I’ve also added two more test cases to check edge cases of sum total being equal to 0 and 100. I would vote to close this. Already on GitHub? and should be invariant. Another problem we have in these long-running threads is that we talk about multiple proposals that change over time. To be sure, completing so many issues would mean thinking in terms of how NUnit now works and fitting our changes into that framework. This has been working well for me until I recently come across TestCaseData from NUnit. NUnit TestCase Arguments / Parameters. The first of these is the attribute. lot of work to make the change - it's just not worth it. In the above example, FakeOrder is used as a stub. The first set of attributes, TestCase and TestCaseSource, define complete test cases. I don't understand the point of this? If we could build it first, then the property would be accessible at the point where we are building the tests. SetCultureAttribute could set IMethodTestSettings.CultureInfo and TestCaseAttribute.BuildFrom could read it when converting strings to dates. Assert DateTime the Right Way MSTest NUnit C# Code. This sequence is followed at every level: assembly, class and method. If we focus on how we wish we had done it, there will be a great many more that are "impossible" to do. Both attributes apply to the test method itself. The following example tests that when we p… -> The fix is probably to have NUnit use this constructor for CultureInfo when applying a SetCulture attribute. It makes a significant difference to how this might be remedied. When we write tests – unit, integration, UI, etc. [TestCase("Hello", DateTime.Today(), "Hello was False")] public void SomeMethod_Always_DoesSomethingWithParameters(string input1, DateTime input2, string expectedResult){ } Another limitation of TestCaseAttribute is that it is not possible to reuse your test case data because the attribute containing the test data is tied to a single TestMethod. Another idea: define an interface which, if implemented, causes a method of the attribute to be called at the time the test is being loaded. we often need to assert DateTimeobjects. NUnit is Open Source software and NUnit 3.0 is released under the MIT license. But of course, it's just an example you created to illustrate the problem. That wouldn't eliminate this issue, of course, which applies to situations where the user wants to set the culture on an individual test case. Yes - I think is should be fixed for @morgen2009's case when the culture is explicitly set. As far as I am concerned, the attributes that feed the test are NUnit code and should be invariant. I can see the logic of your view. I prefer the latter. implicitly converting the string to a DateTime - ignoring NUnit's own — I think that this implicitly re-raises the issue (which I cannot find) of a command line option to set the culture for all the tests currently being run, so that the same test suite can be run for multiple cultures without modifying the test suite. Install the nunit via nuget: PM> install-package nunit Successfully installed 'NUnit 2.6.0.12054'. So the set culture should appear as a property of the parameterized method suite. Tôi thấy TestCasetính năng này trong NUnit khá hữu ích nhÆ° một cách nhanh chóng để chỉ định các tham số kiểm tra mà không cần một phÆ°Æ¡ng thức riêng cho mỗi thá»­ nghiệm. I ran into this in a previous PR. What breaks if the culture is initially stored on the test, before being copied over to the execution context? Perhaps what we should do is collect all such issues now so that we can review their disparate needs when we design the v4 API in the distant future. Modified code below. The method must, of course take a single argument of the same type for this to work. @jnm2 I'd like to hear more about your feeling of hitting a ceiling. You signed in with another tab or window. . However, this reminds me of a very similar thread in which we trade places. (https://github.com/nunit/nunit/blob/master/src/NUnitFramework/framework/Internal/Builders/DefaultTestCaseBuilder.cs#L142-L150), Thought there must be something else too it - that's irritating! var secondDate = new DateTime (2000, 6, day, hour, 0, 0); TimeSpan actual = Calculator .SubtractDates (firstDate, secondDate); Assert .That (actual.Hours, Is .EqualTo (expectedHours)); } TestCase is limited in that the constructor will accept only constant, typeof, or array creation expressions. Perhaps I moved it to backlog too soon. I'd suggest the culture used is IApplyToDiscovery is the nicest idea suggested so far imo. close together in the source. Currently, this uses the Invariant culture. As an immediate fix, how do you fell about specifying the culture on each test case? Ideally, I would break it into two tests, one for passing test cases and one for failing test cases. TestCase arguments are used when we have to use same test case with different data. SendExpiryNotifications (new DateTime (2015, 4, 4, 14, 0, 0, DateTimeKind. FakeOrder was passed into the Purchase class to satisfy the requirements of the constructor. privacy statement. This order has never mattered before, because the property is not used for anything except being reported in the test result. We have 200+ outstanding issues, many quite important. Is there anything similar in MSTest? In xUnit, the most basic test method is a public parameterless method decorated with the [Fact] attribute. Should IMethodTestSettings include an IMethodInfo property and be used instead of current IMethodInfo parameters? nUnit test cases with dates. I can't imagine anyone would expect that, although they may have discovered it works that way and compensated for it. That would be a general solution for many cases and is consistent with the framework architecture. @ChrisMaddock @jnm2 While "How could we implement this" is interesting, I'm still at "Should we? If users really want to convert strings to dates using a culture, they can do it themselves in a TestCaseSource. In NUnit 2.5, individual test cases are sorted alphabetically and executed in that order. Maybe a notice on the nunit-discuss list with a specified time to respond? September 7, 2014 .NET. What is wrong with NUnit using invariant culture to parse the TestCase? This is when the arguments are accessed, so this is when the DateTime would be parsed. @morgen2009 Are you sure your tests fail? If I have a test case to test this method with 2 integers 3 and 4, the test would be called Multiply_3_And_4_Should_Be_12. A third interface (IApplyToDiscovery?) Especially as NUnit is already Modified comparisons to pass the Turkey test. date) { } Below is the example. In the example code above, all the user is effectively testing is how NUnit converts dates. ", While "How could we implement this" is interesting, I'm still at "Should we? So, not a big issue IMO.
