I have software that connects to several marketplace APIs such as Amazon, eBay, Etsy, and so on and imports it into our database.
I've written a basic test. The test provides an order number for each marketplace importer. Each importer attempts to import it's order number. The test then asserts if this order exists in the database.
On one hand, a single Amazon import will call several different functions and does many different things.
On the other hand, all these importers act independently from each other.
Is this unit testing or integration testing.
