If we focus on how we wish we had done it, there will be a great many more that are "impossible" to do. Charlie, On Fri, Jan 27, 2017 at 12:25 PM, Chris Maddock ***@***. I can see the logic of your view. I prefer the latter. privacy statement. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. . You can check the details of Nunit from here. Yes - I think is should be fixed for @morgen2009's case when the culture is explicitly set. close together in the source. SendExpiryNotifications (new DateTime (2015, 4, 4, 14, 0, 0, DateTimeKind. I expect you, as my teammate, to make sure you see the logic of my view too. TestCase attribute and ValuesAttribute do a special conversion from string to DateTime when needed, because it's not possible to specify a DateTime value to an attribute. @jnm2 That would mean very big changes unless we added explicit knowledge of those attributes at load-time. To use it as a Mock, you could do something like this If we're going to write some unit tests, it's easiest to have something we want to test. It should have the following characteristics: It may be a field, a non-indexed property or a method taking no arguments. we often need to assert DateTime objects. at the beginning of a test has solved many similar issues for me. To fully "fix" this, the TestCase and Values attributes would have to be aware of the test property that SetCulture attribute. That's why I was envisioning an IMethodTestSettings because at the point where BuildFrom is called, the method-level test instance has not been instantiated yet. Requiring invariant for the data arguments is clear and consistent. lot of work to make the change - it's just not worth it. As I read the thread, Rob and I came out against the idea, you and Chris for it. If we made SetCultureAttribute implement IApplyToTest instead of IApplyToContext - would it be possible to ensure the attribute is evaluated in time, for the culture to be set on the parent, and then retrieved as the child tests are being built? culture definition here seems inconsistent. It would mean big changes which I'd be in favor of. ... [nunit-discuss] TestCase and ExpectedException in nunit v3. Required fields are marked *. 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. and also ensures that tests run the same way on all machines. Should IApplyToDiscovery be IApplyToTestCreation? As you see above, we provide some values in InlineData and xUnit will create two tests and every time populates the test case arguments with what we’ve passed into InlineData. They would have to anticipate that what the SetCulture attribute means and what it is going to do at the time the test is run. My guess is that we might find a dozen or so that are blocked by the basic design within which we are working. The test framework will call the test method one test case at a time with all the test case’s parameter values. Powered by WordPress and Stargazer. Testing software is always a real challenges for developers and testers, because many types of test cases exists and also come in so many different shapes and sizes. Install the nunit via nuget: PM> install-package nunit Successfully installed 'NUnit 2.6.0.12054'. to your account. This is when the arguments are accessed, so this is when the DateTime would be parsed. could be used to set the culture when the test is being loaded. It's very hard to figure out who is where on an issue in that case, so I can understand how anyone could get confused. This replaces the [Test] attribute we used before, and provides input data to pass to the test method via parameters: Is there anything similar in MSTest? There may have been discussion somewhere, without creating an issue. @jnm2 - just looking at that section of the TestBuilder you linked to - I wonder if the child tests need to be created before the ParameterizedMethodSuite, or if that could be created first, and passed down to BuildFrom so the culture information is available. As far as I am concerned, the culture that is set on the test should only change the behaviour of the test code itself. Definitely not suggesting we change that! Currently, this uses the Invariant culture. These options are a nice gateway to property-based testing as well. This sequence is followed at every level: assembly, class and method. If we do change - then it may cause issues for anyone who's previously encountered this problem and just worked around it - but my thoughts are that 'fixing' this would be a 'less-surprising' approach. At that point, the SetCulture attribute sets the current culture of the execution thread. Copyright © 2020 Ivan Krivyakov. This order has never mattered before, because the property is not used for anything except being reported in the test result. It's basically equivalent to setting the culture at the assembly level, which is already supported. Both attributes apply to the test method itself. TestCaseSource "just" for converting seems for me a bit overhead, I would prefer to have test parameter values closer to the test method header. IApplyToDiscovery is the nicest idea suggested so far imo. I'm also in favor of parsing them invariantly unless there is a SetCulture attribute and then using the given culture. Thanks. You're not using the FakeOrder in any shape or form during the assert. These test method are dependent on each other. good idea to bring CurrentCulture into this at all. Get code examples like "how to pass object as test case in nunit c#" instantly right from your google search results with the Grepper Chrome Extension. (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! . Is this not something of an implementation detail? nUnit test cases with dates. However, the framework’s built-in methods not always can help us. This allows tests to run on any machine no matter the culture. A third interface (IApplyToDiscovery?) 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. 3053 - Conversion from TestCase string parameter to DateTimeOffset, No, for me this is just one use case "date/time in familar format". If you compare your expected DateTime with the real one, they usually won’t be equal because of the seconds, milliseconds, etc. To discover or execute test cases, VSTest would call the test adapters based on your project configuration. Any attributes that modify the test case run. As far as I am concerned, the attributes that feed the test are NUnit code and should be invariant. Currently, for example, SetCulture implements two interfaces. IApplyToDiscovery.Apply should probably receive IMethodInfo and the parent suite too? The solution is to supply test data in runtime, using [ValueSource] attribute. Reply to this email directly, view it on GitHub Have a question about this project? This seems like a rather ugly solution! Unfortunately datetime.date is written in C, and so I couldn’t just monkey-patch out the static date.today() method. 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. <, TestCase and Values do not correctly convert DateTime string in current culture, CanConvertStringToDateTimeInCurrentCulture. Ideally, I would break it into two tests, one for passing test cases and one for failing test cases. I'm also inclined to think that backward compatibility is not a big problem in this case. We can't use various threads because until the test is constructed, we don't know how it is supposed to be run. I don't like [TestCase("12.10.1942", Culture="de-DE")] because it's pure noise for multiple test cases. For example if you want to compare: 2014.10.10 20:20:19 and 2014.10.10 20:20:20 These DateTimes are almost equal to a 1-second difference. test actually uses Invariant culture. I know I've been wrong in the past when I thought some change would not have an impact on many people. We’ll occasionally send you account related emails. I can't find such an issue - or even remember one. When the time comes to think about the next release, I want to be 100% focused on that. This has been working well for me until I recently come across TestCaseData from NUnit. NUnit Assert.AreEqual DateTime Tolerances, NUnit has also added built in support for this using the Within keyword DateTime now = DateTime.Now; DateTime later = now + TimeSpan. @jnm2 I'm not sure what you saw me supporting. Should IMethodTestSettings include an IMethodInfo property and be used instead of current IMethodInfo parameters? Constructing Test Cases. Already on GitHub? In this case, setting a property in the test. If it is a single value type - like numerics or DateTime - it is used directly as the sole argument to the method. I haven't investigated much at all - but I can see the method which converts the TestCaseAttribute parameters is also passed the parent suite Test. ", Sorry - I noticed I hadn't answered that question, but thought the conversation had moved on further. If you compare your expected DateTime with the real one, they usually won’t be equal because of the seconds, milliseconds, etc. Especially as NUnit is already Asking that the developer use invariant culture does not change the tests in any way and also ensures that tests run the same way on all machines. We can see the output below: The [Pairwise] attribute works similarly to the [Combinatorial] attribute, but rather than executing every input against each other, it reduces the test cases to only those that actually test a unique combination. CultureInfo.CurrentCulture = new CultureInfo("de-DE", false) This framework is very easy to work with and has user friendly attributes for working. @CharliePoole Gotcha. PM> Now we have to create a Moles file on the mscorlib assembly (This is the one DateTime sits in). 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. For example, in the above case, we fixed the age of employee as 60. 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. we often need to assert DateTimeobjects. If you do override ToString(), to preclude NUnit from skipping test cases it considers duplicates then you need to ensure the override of ToString() returns unique values for each object, or use the separate id parameter technique mentioned earlier. . Whichever is better for the test case. What breaks if the culture is initially stored on the test, before being copied over to the execution context? The sourceName, represents the name of the source that will provide the arguments. Maybe a notice on the nunit-discuss list with a specified time to respond? In mos… The TestCase Attribute. The method must, of course take a single argument of the same type for this to work. Which is better during test creation- actually setting the thread's culture, or passing in the correct CultureInfo to DateTime.Parse? So you could then use... Hmmm... that may be the solution. NUnit TestCase Execution Order. These provide two mechanisms that allow you to easily run the same test with multiple input data. If set to a non-empty string, then Ignore is assumed to be true. You can specify the date as a constant string in the TestCase attribute and then specify the type as DateTime in the method signature. Order of Execution. I'd suggest the culture used is If we could build it first, then the property would be accessible at the point where we are building the tests. What is wrong with NUnit using invariant culture to parse the TestCase? So, not a big issue IMO. Alternatively, you could use a TestCaseSource attribute on a method that yields DateTimes constructed in any way you like. Why to not use System.Globalization.CultureInfo.CurrentCulture instead of System.Globalization.CultureInfo.InvariantCulture? We have 200+ outstanding issues, many quite important. either invariant *or* explicitly set by the user - I don't think it's a As an immediate fix, how do you fell about specifying the culture on each test case? TestCaseData allows you to set as many arguments for the test as you want and allows you to have spaces in your test name.
