Testgetriebene Entwicklung heißt, Tests vor dem Produktivcode zu schreiben (Test-first). Aber auch Test-last führt zu stabilen Systemen. Was ist der Unterschied zwischen TDD und Test-First? Was macht einen Unit-Test aus? Dürfen Ressourcen in Unit Tests verwendet werden?

Test First Test First Forces you to Design for Testability Upfront VideoB2 First speaking test (from 2015) - Victoria and Edward
Effective modular design yields components that share traits essential for effective TDD. A key technique for building effective modular architecture is Scenario Modeling where a set of sequence charts is constructed, each one focusing on a single system-level execution scenario.
The Scenario Model provides an excellent vehicle for creating the strategy of interactions between components in response to a specific stimulus.
Each of these Scenario Models serves as a rich set of requirements for the services or functions that a component must provide, and it also dictates the order that these components and services interact together.
Scenario modeling can greatly facilitate the construction of TDD tests for a complex system. In a larger system the impact of poor component quality is magnified by the complexity of interactions.
This magnification makes the benefits of TDD accrue even faster in the context of larger projects. However, the complexity of the total population of tests can become a problem in itself, eroding potential gains.
It sounds simple, but a key initial step is to recognize that test code is also important software and should be produced and maintained with the same rigor as the production code.
Creating and managing the architecture of test software within a complex system is just as important as the core product architecture.

Or is it? So TDD's relationship to quality is problematic at best. Its relationship to productivity is more interesting. I hope there's a follow-up study because the productivity numbers simply don't add up very well to me.

By creating tests first your design will be influenced by a desire to test everything of value to your customer. Your design will reflect this by being easier to test.
There is a rhythm to developing software unit test first. You may then decide to make some design changes to the code, to make it easier to test.
During test driven development TDD you force yourself to think about both the contract as mentioned above , and the testability of the component, before you start implementing it.
This way you may naturally design components that are easier to test, rather than having to redesign them later. Once the unit test is implemented, you can implement the unit the component assert by assert.
In other words, you run your unit test, see which assert that fails, then implement whatever it takes to make that assert succeed, then move on to the next assert.
Sometimes, when developing the test after the components, you either forget, skip, or write less good tests.
