Maintain code quality of unit tests

One of the most powerful JetBrains Rider features, code inspection, comes in handy when you write unit tests. In addition to hundreds of general-purpose inspections, there is also a number of dedicated inspections that target problems specific to unit tests:

NUnit (30 inspections)

These inspections detect code issues related to NUnit tests.

Inspection

Default severity

NUnit. Async test method must return Task or Task<T>

Warning

NUnit. Cannot resolve symbol in TestCaseSource or ValueSource attribute

Warning

NUnit. Duplicate values

Warning

NUnit. Ignored parameter attribute

Warning

NUnit. Implicitly unspecified null values

Warning

NUnit. Incompatible argument type or incorrect argument value

Warning

NUnit. Incompatible expected result type or incorrect value

Warning

NUnit. Incorrect range bounds. 'to' must be greater than or equal to 'from'

Warning

NUnit. Mismatch of the range step sign

Warning

NUnit. Missing arguments in TestCase attribute

Warning

NUnit. Missing expected result for non-void test method

Warning

NUnit. No values provided in the attributes

Warning

NUnit. Non-public test method

Warning

NUnit. Range 'step' parameter value must be non-zero

Warning

NUnit. Redundant argument in TestCase attribute

Warning

NUnit. Redundant argument instead of ExpectedResult

Warning

NUnit. Redundant expected result for void test method

Warning

NUnit. Specified attribute values produce too many tests

Disabled

NUnit. Specified values are not compatible with the test parameter type

Warning

NUnit. Test case Result property duplicates ExpectedResult

Warning

NUnit. Test case Result property is obsolete

Warning

NUnit. Test case source must be field, property, or method

NUnit. Test case source must be non-abstract and implement IEnumerable

Warning

NUnit. Test case source must be static

Warning

NUnit. The maximum range value is not reachable with the step value

Warning

NUnit. Values for test method parameters are not provided

Warning

NUnit. Values in range do not fit the type of the test parameter

Warning

NUnit.AutoFixture. Incompatible argument type or incorrect argument value

Warning

NUnit.AutoFixture. Missed Test or TestFixture attribute

Warning

NUnit.AutoFixture. Redundant argument in InlineAutoData attribute

Warning
