Question

Similar to What is the best format to store test data in a file? I want make some tests with data in my class.
This class must receive a list of data with date and value. So basically, I just need to store values and when I read I can say the initial date and just add a constant to get next correspondent date – value. Something like: 1234.56;6543.21;1111.22

I’m using csv right now, but I’m wondering if some xml, sqlite or pure IEnumerable in C# will be a better option. Some experience about this?

Answer 1

Choose the simplest thing that works and is maintainable. In order of preference

• If you your data is relatively simple (as depicted in the question), you could do it in-memory within the test-fixture class. Use factory methods / types to get the expected Data.
• If you want structured data that is easy to read/edit, use CSV (everyone knows how to use Excel) or YAML (another text-based format) or a custom text file.
• On the other hand, if you need structured schema-valid data, then you could choose something like XML or canned test-databases.
