Cause

An instance of [DataRow] is not following one or multiple points of the required DataRow layout.

MSTest turns each [DataRow] into arguments for a test-method invocation. The attribute doesn't declare a test by itself:

Requirement	Reason
Apply `[DataRow]` to a method marked with `[TestMethod]` or a derived attribute.	`[TestMethod]` identifies the test entry point. Without it, MSTest doesn't invoke the method as a test, regardless of the supplied data.
Supply an argument count that matches the method's parameters, including any supported `params` handling.	MSTest binds the row's values to the parameter list. Missing or extra arguments can prevent the test method from being invoked.
Supply values compatible with the parameter types.	The runner must pass each value to its corresponding parameter. An incompatible value causes an argument-binding failure instead of exercising the behavior the test intends to check.

For supported argument shapes and examples, see Data-driven testing.

Ensure that the DataRow instance matches the required layout described above.

Do not suppress a warning from this rule. If you ignore this rule, flagged instances will be either skipped or result in runtime error.

If you just want to suppress a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable MSTEST0014
// The code that's violating the rule is on this line.
#pragma warning restore MSTEST0014

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.
