Inline data-driven testing is the most basic or simplest way of writing data-driven tests using the xUnit.net framework. Inline data-driven tests are written using the InlineData attribute, which is used to decorate the test method in addition to the Theory attribute:
[Theory, InlineData("arguments")]
Inline data-driven tests can be used when the test method requires parameters that are simple and does not accept class instantiation as an InlineData parameter. The major drawback of using the inline data-driven test is the lack of flexibility. Inline data used with a test cannot be reused with another test.
When you are using the InlineData attribute in a data theory, the data rows are hard-coded and passed inline into the test method. The desired data to be used for the test can be of any data type and is passed as a parameter into the InlineData...
