Moq1001: Mocked interfaces cannot have constructor parameters

Item	Value
Enabled	True
Severity	Warning
CodeFix	False

---

Mocking interfaces requires generating a class on-the-fly that implements the interface. That generated class is constructed using the default constructor. To fix:

• Remove the constructor parameters

Examples of patterns that are flagged by this analyzer

interface IMyService
{
    void Do(string s);
}

var mock = new Mock<IMyService>("123"); // Moq1001: Mocked interfaces cannot have constructor parameters

Solution

interface IMyService
{
    void Do(string s);
}

var mock = new Mock<IMyService>();

Suppress a warning

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 Moq1001
var mock = new Mock<IMyService>("123"); // Moq1001: Mocked interfaces cannot have constructor parameters
#pragma warning restore Moq1001

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

[*.{cs,vb}]
dotnet_diagnostic.Moq1001.severity = none
