TDD in a text file import project

Question

I’m just starting, and yes, I haven’t written any tests yet (I’m not a fundamentalist, I don’t like compilation errors just because there is no test), but I’m wondering where to start the project, which analyzes the records of flat files of a fixed length in accordance with XML mapping, into a class that is a superset of all file layouts before writing (with conversion) class information to a database table.

There are so many external factors, and I don’t want to make fun of them, so where and how would it be a good way to start the test managing this project?
