•2. In NUnit 2.5, individual test cases are sorted alphabetically and executed in that order. While I’m not sure why you’d ever want to do this, the Values attribute can be applied to boolean parameters, allowing NUnit to automatically inject both true and false values. The first way to create data driven tests is by using the [TestCase] attribute that NUnit provides. This replaces the [Test] attribute we used before, and provides input data to pass to the test method via parameters: Here is an example of a test being run three Note that the [TestCase] attribute can take any number of parameters, including input and expected output. Replace the [Test] attribute with the [TestCase] attribute. TestCaseAttribute (NUnit 2.5) TestCaseAttributeserves the dual purpose of marking a method with parameters as a test method and providing inline data to be used when invoking that method. Using the TestCase Attribute. parameters as a test method and providing inline data to be used when The first project contains the math class with a factorial static method that helps you to calculate the factorial of a number. The Combinatorial attribute ensures that NUnit generates tests for all possible combinations of your test input. TestCase. Sometimes we need to execute test methods in a particular order. NUnit TestRunner will pick a string array from GetEnumerator method and pass one by one into the test method. These provide two mechanisms that allow you to easily run the same test with multiple input data. NUnit TestCase Execution Order. which may also carry other attributes providing test data, such as the It also provides the inline data that needs to be used when that particular method is invoked. Attribute used to provide descriptive text about a test case or fixture. •1. Code Inspection: NUnit. We use this workaround with TestCase for having a human-readable test name supplied by NUnit instead of coding a custom attribute. named parameters, which may be used as follows: Copyright © 2002-2015 NUnit.org. It is important to note that the InlineAutoData attribute suffers of the same restrictions of the TestCase attribute regarding which types can be used in the attribute. So we can use Ignore property to mark test case as ignore. •5. All NUnit attributes are contained … Note: Because arguments to .NET attributes are limited in terms of the Types that may be used, NUnit will make some attempt to convert the supplied values using Convert.ChangeType() before supplying it to the test. You could manually create TestCase entries to accomplish this, but what happens if a change to your inputs occurs? TestCase arguments are used when we have to use same test case with different data. All Rights Reserved. This inspection draws your attention to the fact that the expected result is missing in the Test or TestCase attribute for a test method with a return value. In our last tutorial, we learned about NUNit TestFixture attribute. TestCase attribute is used for two purposes. You can add multiple [TestCase] attributes for a single test method, and specify the combinations of input and expected output parameters that the test method should take. There are other NUnit attributes that enable you to write a suite of similar tests. All NUnit attributes are contained in the NUnit.Framework namespace. But by using ExpectedResult property, we can also specify different results for different parameters. It marks a method to Test Method. For that, NUnit provides the Order attribute. It can appear one or more times on the test method, with each appearance carrying values for the test case. the framework assembly, nunit.framework.dll. For different ages we have to write different test cases. The examples will be done with NUnit versions 2.6, but I’ve applied these same techniques to MBunit, XUnit, and am currently using them with the NUnit beta 3.0. This attribute tells the test runner what the result of the test method should be. Specifically the [TestCase] attribute so I can parameterise tests. And in many cases we use TestCase attribute for its intended purpose as well. Using the NUnit TestCase method-level attribute. In Part 1 of this series, we took a quick look at two common, mature tools for unit testing C# code - NUnit and Moq.We also covered some basic unit testing philosophies and ways to improve your code's testability. More practically, NUnit offers a Range attribute which works similarly to the Valuesattribute, but generates a range of possible values. Data-Driven Testing with NUnit.
