When Should I Use Xunit Fact?
They test invariant conditions 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.
What is the difference between fact and theory tests in xUnit?
In an Xunit test class or fixture, there are two kinds of tests: Fact tests and Theory tests. The small, but very important, difference is that Theory tests are parameterized and can take outside input. Fact tests, however, are not parameterized and cannot take outside input.
What is the difference between inlinedata and theory in xUnit?
[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.
What is xUnit theory in testing?
xUnit Theory: Working With InlineData, MemberData, ClassData. 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.
What is difference between Fact and Theory in xUnit?
What is the difference between a fact and a theory in xUnit?
A Fact, in XUnit tests, is by definition a test method that has no inputs. Consequently, it is run as a single test: arrange once, act once, assert once. In contrast, a Theory in XUnit attribute specifies that a test method can have inputs, and that the method needs to be tested for many different combinations of inputs.
What is Fact in xUnit test?

What is Theory in unit testing?
What xUnit test type should you use to test an invariant condition?
Why is a fact test unnecessary in xUnit?
Why is it unnecessary, you ask? Because XUnit provides a way to do this kind of testing much more concisely using the [Theory] and [InlineData] attributes. A Fact, in XUnit tests, is by definition a test method that has no inputs. Consequently, it is run as a single test: arrange once, act once, assert once.
What is the difference between [teardown] and [fact] in xUnit?
The decision to do away with [TearDown] was made as the investors of xUnit felt that a lot of unnecessary code was run before every single test execution. This attribute is used when data-driven tests have to be executed. In such cases, [Theory] has to be used instead of [Fact] attribute
Which is better NUnit or xUnit?
What is the difference between xUnit and NUnit?
xUnit is a unit testing tool for .Net Framework which was released in 2007 as an alternative for Nunit. xUnit has attributes for the execution of tests but is not similar to NUnit. [Fact] and [Theory] attributes are similar to [Test]

What is the difference between a fact and a theory?
Facts are tests which are always true. They test invariant conditions Theories are tests which are only true for a particular set of data We use xUnit Fact when we have some criteria that always must be met, regardless of data.
What is the difference between information and truth?
It’s an object, an article, a fragment of information, a bit of trivia. Truth, on the other hand, is all about meaning. To put it another way, discerning truth is a matter of interpreting the facts.
