Xunit has a nice feature: you can create one test with a Theory attribute and put data in InlineData attributes, and xUnit will generate many tests, and test them all.

I want to have something like this, but the parameters to my method are not 'simple data' (like string, int, double), but a list of my class:

public static void WriteReportsToMemoryStream(
    IEnumerable listReport,
    MemoryStream ms,
    StreamWriter writer) { ... }
