  1. Infrastructure can be tested using integration tests. if you have a data ingestion and processing flow, you can feed it fake data from a blob containing test samples (or some other methods, depending on your case). TDD does not refer just to unit testing, it refers to testing in general.

  2. You can write any integration test for any codebase in its implementation language. He choose a BDD framework in this case to present the test case in a slightly more human readable way (using Cucumber), but the underlying code that does the actual testing has the same language as the codebase itself (in this case, Java)

  3. No. The good tests hide the implementation details of StringList. You do not check item addition by looking as size, you call a Size() method. You also do not ask the item using direct lookup, but through a method. This permits me to change the underlying implementation of StringList to whatever I like as long as that implementation is passing the tests.
