Was this related to my point Charlie? — 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. Notka: NUnit konwertuje typy za pomocą metody Convert.ChangeType. Letting a SetCulture change which culture is used for data arguments also If you compare your expected DateTime with the real one, they usually won’t be equal because of the seconds, milliseconds, etc. Modified code below. Another problem we have in these long-running threads is that we talk about multiple proposals that change over time. @nunit/core-team @nunit/framework-team please chime in with your thoughts. You can specify the date as a constant string in the TestCase attribute and then specify the type as DateTime in the method signature. NUnit will construct it using either the default constructor or - if arguments are provided - the appropriate constructor for those arguments. That would be a general solution for many cases and is consistent with the framework architecture. There may have been discussion somewhere, without creating an issue. I expect you, as my teammate, to make sure you see the logic of my view too. We could also change it to use the system culture, but that would not help either, since the culture you are trying to use may not be the system culture. This order has never mattered before, because the property is not used for anything except being reported in the test result. I'd also prefer to avoid doing anything based on current culture - we've been bit before by different cultures on different machines - sounds like we allowed this inside the test building logic, it could take a bit of untangling. The test builder interface is called to create the test. The first of these is the attribute. NUnit TestRunner will pick a string array from GetEnumerator method and pass one by one into the test method. Utc)); Making the clock a service. As far as I am concerned, the attributes that feed the test are NUnit code and should be invariant. 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. In the above example, FakeOrder is used as a stub. In this case, setting a property in the test. TestCase arguments are used when we have to use same test case with different data. @jnm2 I'm not sure what you saw me supporting. These test method are dependent on each other. Alternatively, you could use a TestCaseSource attribute on a method that yields DateTimes constructed in any way you like. The sourceName, represents the name of the source that will provide the arguments. So, not a big issue IMO. Should IApplyToDiscovery be IApplyToTestCreation? Any attributes that modify the test case run. https://github.com/nunit/nunit/blob/master/src/NUnitFramework/framework/Internal/Builders/DefaultTestCaseBuilder.cs#L142-L150, https://github.com/notifications/unsubscribe-auth/ACjfhUna3-JEQwWRJ6LxAF5pjcG4XtAyks5rWlLTgaJpZM4LtbZq. Furthermore, the DateTime.Now is a static property so a stub type can't be used here. @morgen2009 Are you sure your tests fail? [TestCase("2000-01-01")] public void Foo(DateTime? For example, in the above case, we fixed the age of employee as 60. Sign in @ChrisMaddock I was asking the question because it seems to me we should have some standard approach when we are about to make a change that could impact some people. That's not consensus. In the example code above, all the user is effectively testing is how NUnit converts dates. Thanks. That doesn't put me in agreement with you. I spend almost no time thinking about those flaws most of the time because there is too much to do. @jnm2 I wrote that immediately after the line that states my preference for the opposite. we often need to assert DateTimeobjects. What do you think about? The NUnit Project is a member of the .NET Foundation.NUnit is run by the core team, Rob Prouse, Charlie Poole, Terje Sandstrom, Chris Maddock, Joseph Musser and Mikkel Nylander Bundgaard.The .NET Foundation will provide guidance and support to help ensure the future of the project.. For convenience it'd be nice if TestCase supported nullable types so you could have for example a DateTime? Successfully added 'NUnit 2.6.0.12054' to MyTests. But of course, it's just an example you created to illustrate the problem. But by using the TestCase parameters we can use same test method for different ages. If we focus on how we wish we had done it, there will be a great many more that are "impossible" to do. I prefer the latter. Ideally, I would break it into two tests, one for passing test cases and one for failing test cases. Definitely not suggesting we change that! <, TestCase and Values do not correctly convert DateTime string in current culture, CanConvertStringToDateTimeInCurrentCulture. But that leaves a lot of work we can accomplish. IApplyToDiscovery is the nicest idea suggested so far imo. Assert DateTime the Right Way MSTest NUnit C# Code. However, this reminds me of a very similar thread in which we trade places. . Successfully merging a pull request may close this issue. 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. At a later stage - in the case of a gui, it could be much later - the test is executed. ***> wrote: As above, I'm less of a fan of using current culture for anything - now you mention it, backwards compatibility is another good reason not to do that. parameter instead of having to use TestCaseSource. But the more I think about it, the less obvious the decision between the two seems. Whichever is better for the test case. I've been noticing us hitting a ceiling with various aspects of the current system in recent issues and ever since one of my first PRs. Constructing Test Cases. 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? privacy statement. This would allow CurrentCulture to be used for all test where culture mattered, and CurrentCulture would be the culture set on the command line. I said there are some limitation on what we can pass in InlineDataattribute, look what happens when we try to pass a new instance of some object: We can pass this kind of data to our theory with Cl… As I read the thread, Rob and I came out against the idea, you and Chris for it. The IApplyToContext interface is used to set the culture of the thread being used to run the test when execution starts. Required fields are marked *. I find the TestCase feature in NUnit quite useful as a quick way to specify test parameters without needing a separate method for each test. We can't use various threads because until the test is constructed, we don't know how it is supposed to be run. Currently, this uses the Invariant culture. Are there other cases where that's not a valid solution? Testing this method is problematic because the program depends on DateTime.Now, a method that depends on the computer's clock, an environment-dependent, non-deterministic method. 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. Is this not something of an implementation detail? Already on GitHub? That's a bit surprising as I would expect them to be invalid due to a failure to convert from string to DateTime. Có But that's a different story. I know I've been wrong in the past when I thought some change would not have an impact on many people. . It should have the following characteristics: It may be a field, a non-indexed property or a method taking no arguments. The parent suite test is the grandparent of the test cases and the shared parent of each method, so for TestCaseAttribute it's always the entire fixture. Thanks in … It would mean big changes which I'd be in favor of. FakeOrder was passed into the Purchase class to satisfy the requirements of the constructor. I ran into this in a previous PR. Specifies the reason for ignoring this test case. If you used a string parameter and converted it in your test, it would work as you expect. My comments often tend toward pointing out how NUnit works right now, not because I think it's perfect, but only because it is what it is. I wouldn't do it, however, if it required a 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. I haven't looked at any other ITestBuilders to see if it would affect anything else. Nunit within datetime. . Powered by WordPress and Stargazer. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. For that, NUnit provides the Order attribute. (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! This replaces the [Test] attribute we used before, and provides input data to pass to the test method via parameters: This sequence is followed at every level: assembly, class and method. To discover or execute test cases, VSTest would call the test adapters based on your project configuration. I can't find such an issue - or even remember one. So NUnit.TestAdapter exists for that purposes. As far as I am concerned, the attributes that feed the test are NUnit code If users really want to convert strings to dates using a culture, they can do it themselves in a TestCaseSource. IApplyToDiscovery.Apply should probably receive IMethodInfo and the parent suite too? Is there anything similar in MSTest? We have 200+ outstanding issues, many quite important. With NUnit 2.5.1, the individual cases are not sorted, but are executed in the order in which NUnit … The problem here is that NUnit uses various attributes at different points in the life cycle of the test. Well, I can see both sides. 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. Since the cases are created by many different attributes, each one of them would need to be aware of the presence of a SetCultureAttribute and act on it. The test framework will call the test method one test case at a time with all the test case’s parameter values. 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. If it results in too much code duplication, you could always call a third private method. You can think of them like rows in a table containing values for each of the test’s parameters. Copyright © 2020 Ivan Krivyakov. You signed in with another tab or window. The IApplyToTest interface is used to set a property on the test, which indicates the culture used for reporting purposes. I can't imagine anyone would expect that, although they may have discovered it works that way and compensated for it. Especially as NUnit is already This avoids duplicate tests and longer executions. Ok... so having given some workarounds, which I agree are not ideal, are there options to "fix" this or is it something we don't want to fix. I can understand the confusion of defining a test to be de-DE, and then finding part of that test actually uses Invariant culture. [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. Your email address will not be published. Reply to this email directly, view it on GitHub Currently, this uses the Invariant culture. I expect that when I change the TestExecutionContext.CurrentCulture using SetCultureAttribute for test / test fixture, the converter should use the new culture info. Especially as NUnit is already implicitly converting the string to a DateTime - ignoring NUnit's own culture definition here seems inconsistent. nUnit has a great feature of running multiple similar test cases via data-driven approach: However, that does not work with dates, since DateTime is not a primitive type and cannot be used in an attribute. @jnm2 I'd like to hear more about your feeling of hitting a ceiling. ", While "How could we implement this" is interesting, I'm still at "Should we? test actually uses Invariant culture. These options are a nice gateway to property-based testing as well.

Definitely not suggesting we change that! Przepis jest następujący – Atrybutowi metody TestCase przypisujemy kolejno wartości, które są odwzorowaniem parametrów naszego testu. I'd suggest the culture used is PM> Now we have to create a Moles file on the mscorlib assembly (This is the one DateTime sits in). That also has the advantage of making the tests clearer. By implementing IApplyToDiscovery.Apply(IMethodTestSettings) or similar, SetCultureAttribute could modify IMethodTestSettings.CultureInfo. What breaks if the culture is initially stored on the test, before being copied over to the execution context? However, as I already explained, at the time we are doing the conversion, the culture has not yet been changed to match the SetCulture attribute. 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. NUnit uses the parameters to differentiate individual test cases. @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. When the time comes to think about the next release, I want to be 100% focused on that. . we often need to assert DateTime objects. I would vote to close this. [In this example, it would do the same thing that it does at execution time, but that might not be the case for every attribute.]. Or is it just a matter of being able to use the format you are familiar with? It would only apply if somebody used SetCulture on a parameterized method and actually expected the set culture to be ignored at load time and not used till run time. IMO we have a lot of power in the existing design along with a few flaws I would love to fix in some future major release. This framework is very easy to work with and has user friendly attributes for working. Otherwise, it should continue to use Invariant culture. In mos… Again, I saw your, Chris' and my support for the idea. I like IApplyToDiscovery. could be used to set the culture when the test is being loaded. To fully "fix" this, the TestCase and Values attributes would have to be aware of the test property that SetCulture attribute. SetCultureAttribute could set IMethodTestSettings.CultureInfo and TestCaseAttribute.BuildFrom could read it when converting strings to dates. How to run Nunit selected test cases through command line: Udhaya Kumar: 9/30/13 5:58 AM: Hi All, This will be more helpful to me if any idea to run Nunit selected test cases through command line. @CharliePoole It fails on assertion, because I expect the string date in DD.MM.YYYY format and converter interpretes it as MM.DD.YYYY, It fails on assertion, because I expect the string date in DD.MM.YYYY format and converter interpretes it as MM.DD.YYYY, I refuse to specify date formats at all unless I can put the year first, then the month, then the day.
