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. You are receiving this because you were mentioned. Any attributes that modify the test case run. It would mean big changes which I'd be in favor of. privacy statement. For convenience it'd be nice if TestCase supported nullable types so you could have for example a DateTime? [TestCase("2000-01-01")] public void Foo(DateTime? and also ensures that tests run the same way on all machines. Rob Prouse: What do you think about? Thank everyone for quick response. My guess is that we might find a dozen or so that are blocked by the basic design within which we are working. Because of that we need a better way to assert DateTimes with some delta. I saw again the TestCaseAttribute and ValuesAttribute classes. [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. <, TestCase and Values do not correctly convert DateTime string in current culture, CanConvertStringToDateTimeInCurrentCulture. 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'm also in favor of parsing them invariantly unless there is a SetCulture attribute and then using the given culture. 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. We could use the current culture as @morgen2009 suggests. FakeOrder was passed into the Purchase class to satisfy the requirements of the constructor. Install the nunit via nuget: PM> install-package nunit Successfully installed 'NUnit 2.6.0.12054'. [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.]. I wouldn't do it, however, if it required a @jnm2 I'm not sure what you saw me supporting. To discover or execute test cases, VSTest would call the test adapters based on your project configuration. Powered by WordPress and Stargazer. It should have the following characteristics: It may be a field, a non-indexed property or a method taking no arguments. Notka: NUnit konwertuje typy za pomocą metody Convert.ChangeType. Otherwise, it should continue to use Invariant culture. 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. The first of these is the attribute. Thanks in … confusion of defining a test to be de-DE, and then finding part of that 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. This would allow CurrentCulture to be used for all test where culture mattered, and CurrentCulture would be the culture set on the command line. 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. Should IApplyToDiscovery be IApplyToTestCreation? In the example code above, all the user is effectively testing is how NUnit converts dates. A third interface (IApplyToDiscovery?) 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. SetCultureAttribute could set IMethodTestSettings.CultureInfo and TestCaseAttribute.BuildFrom could read it when converting strings to dates. culture definition here seems inconsistent. That doesn't put me in agreement with you. If users really want to convert strings to dates using a culture, they can do it themselves in a TestCaseSource. and also ensures that tests run the same way on all machines. I expect you, as my teammate, to make sure you see the logic of my view too. Which is better during test creation- actually setting the thread's culture, or passing in the correct CultureInfo to DateTime.Parse? IApplyToDiscovery is the nicest idea suggested so far imo. In order to learn how to write good test cases, we must first understand what is a test case and why do we need it. 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. The IApplyToContext interface is used to set the culture of the thread being used to run the test when execution starts. nUnit has a great feature of running multiple similar test cases via data-driven approach: [TestCase ("", "")] [TestCase ("q", "q")] [TestCase ("xyz", "zyx")] public void TestStringReverse (string s, string expectedResult) { var result = Reverse (s); Assert.AreEqual (expectedResult, result); } However, that does not work with dates, since DateTime is not a primitive … nUnit test cases with dates. However, this reminds me of a very similar thread in which we trade places. I'm going to use the super-trivial and clichéd \"calculator\", shown below:The Add method takes two numbers, adds them together and returns the result.We'll start by creating our first xUnit test for this class. parameter instead of having to use TestCaseSource. Is this not something of an implementation detail? Since we can't actually instantiate the test until BuildFrom is finished, it would be cool if BuildFrom was passed some common currency such as IMethodTestSettings in addition to IMethodInfo. It's basically equivalent to setting the culture at the assembly level, which is already supported. In this case, setting a property in the test. I don't understand the point of this? If you compare your expected DateTime with the real one, they usually won’t be equal because of the seconds, milliseconds, etc. 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. But by using the TestCase parameters we can use same test method for different ages. NUnit will construct it using either the default constructor or - if arguments are provided - the appropriate constructor for those arguments. NUnit provides a feature called Parameterized Tests. The IApplyToTest interface is used to set a property on the test, which indicates the culture used for reporting purposes. As an immediate fix, how do you fell about specifying the culture on each test case? There's no threading issue here, since this is not run at execution time. However, the framework’s built-in methods not always can help us. By implementing IApplyToDiscovery.Apply(IMethodTestSettings) or similar, SetCultureAttribute could modify IMethodTestSettings.CultureInfo. It makes a significant difference to how this might be remedied. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Utc)); Making the clock a service. I'd suggest the culture used is either invariant or explicitly set by the user, This would be great, if would be possible (for example by specifying test assembly culture), ... ignoring NUnit's own culture definition here seems inconsistent, For me the unit tests like contract specification. Successfully merging a pull request may close this issue. Yes - I think is should be fixed for @morgen2009's case when the culture is explicitly set. You can think of them like rows in a table containing values for each of the test’s parameters. Nunit within datetime. I'm also inclined to think that backward compatibility is not a big problem in this case. If we could build it first, then the property would be accessible at the point where we are building the tests. So NUnit.TestAdapter exists for that purposes. As far as I am concerned, the attributes that feed the test are NUnit code 3053 - Conversion from TestCase string parameter to DateTimeOffset, No, for me this is just one use case "date/time in familar format". These test method are dependent on each other. 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. @jnm2 That would mean very big changes unless we added explicit knowledge of those attributes at load-time. I haven't looked at any other ITestBuilders to see if it would affect anything else. 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. If it results in too much code duplication, you could always call a third private method. You signed in with another tab or window. Maybe a notice on the nunit-discuss list with a specified time to respond? Another problem we have in these long-running threads is that we talk about multiple proposals that change over time. to your account. 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? In the case of this example, the SetCulture attribute would no longer be needed. The first set of attributes, TestCase and TestCaseSource, define complete test cases. Why to not use System.Globalization.CultureInfo.CurrentCulture instead of System.Globalization.CultureInfo.InvariantCulture? That would be a general solution for many cases and is consistent with the framework architecture. This has been working well for me until I recently come across TestCaseData from NUnit. 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. 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. For example, in the above case, we fixed the age of employee as 60. Are there other cases where that's not a valid solution? -> The fix is probably to have NUnit use this constructor for CultureInfo when applying a SetCulture attribute.
