xUnit support two different types of unit test, Fact and Theory. We use xUnit Fact when we have some criteria that always must be met, regardless of data. For example, when we test a controller’s action to see if it’s returning the correct view. xUnit Theory on the other hand depends on set of parameters and its … Näytä lisää

Feb 25, 2017 · xUnit Theory With InlineData This is a simplest form of testing our theory with data, but it has its drawbacks, which is we don’t have much flexibility, let’s see how it works first. 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 .

Oct 4, 2022 · The following xUnit attributes enable writing a suite of similar tests: [Theory] represents a suite of tests that execute the same code but have different input arguments. [InlineData] attribute specifies values for those inputs. Rather than creating new tests, apply the preceding xUnit attributes to create a single theory.

Jul 13, 2016 · Both [Fact] and [Theory] attributes are defined by xUnit.net. The [Fact] attribute is used by the xUnit.net test runner to identify a 'normal' unit test: a test method that takes no method arguments. The [Theory] attribute, on the other, expects one or more DataAttribute instances to supply the values for a Parameterized Test's method arguments.
