xUnit1020 Error

MemberData must reference a property with a getter

Cause

This rule is triggered when your [MemberData] attribute points to a property without a public getter.

Reason for rule

[MemberData] attributes which point to write-only properties will fail at runtime, since the property value cannot be read to retrieve the data.

How to fix violations

To fix a violation of this rule, update the data member to have a getter.

Examples

Violates

using System.Collections.Generic;
using Xunit;

public class xUnit1020
{
    public static IEnumerable<object[]> TestData { private get; set; }

    [Theory]
    [MemberData(nameof(TestData))]
    public void TestMethod(string greeting, int age) { }
}

Does not violate

using System.Collections.Generic;
using Xunit;

public class xUnit1020
{
    public static IEnumerable<object[]> TestData { get; set; }

    [Theory]
    [MemberData(nameof(TestData))]
    public void TestMethod(string greeting, int age) { }
}
