Code Inspection: NUnit. Missing expected result

tip

You can suppress this inspection to ignore specific issues, change its severity level to make the issues less or more noticeable, or disable it altogether.

This inspection draws your attention to the fact that the expected result is missing in the Test or TestCase attribute for a test method with a return value. ReSharper also suggests a quick-fix that adds the ExpectedResult argument with the default value of the compatible type, which you can then replace with a desired value.

[TestCase] // Warning: missing ExpectedResult
public async Task<int> Test()
{
    // do something
    return await Task.FromResult(100);
}

[TestCase(ExpectedResult = 0)]
public async Task<int> Test()
{
    // do something
    return await Task.FromResult(100);
}
