Class AutoMemberDataSourceAttribute

Namespace: AutoFixture.TUnit
Assembly: AutoFixture.TUnit.dll

Provides a data source for a data theory, with the data coming from one of the following sources and combined with auto-generated data specimens generated by AutoFixture:

1. A static property
2. A static field
3. A static method (with parameters) The member must return test data in any shape supported by TUnit MethodDataSource (for example IEnumerable<object?[]>, IEnumerable<T>, tuples, or a single value).
