What you will gain after the course

  • The Development Environment Changed by LLM and the Role of Human Developers

  • The Meaning and Application of TDD as a Solution to Complement LLM Non-determinism

In the AI era,
what it means to live as a developer

AI coding tools have deeply permeated the daily routine of development. Simply describing functionality generates code immediately, and development speed and productivity have improved noticeably. Now, the act of 'writing code' itself is no longer a core responsibility of developers. However, this means we now face more fundamental questions as developers.

✅ "What are we building right now?" (Problem Definition)
✅ "Is this code really working as we expected?" (Result Verification)
✅ "When problems arise, where should we start checking and how can we improve?" (Refactoring)

While AI is handling many tasks for us, the responsibility to define what to build and validate the results still remains with developers . Now that we're collaborating with AI, the developer's role has become clearer, and we need practical and reliable ways to fulfill that responsibility.


Why TDD Now?

First, by writing tests before implementing functionality, you can more accurately define 'what to build' and communicate clear goals to AI as well.

Second, even if AI quickly generates code for you, whether that code works as expected is another matter entirely. Automated testing is the most reliable way to repeatedly verify this.

Third, most importantly, now AI also suggests test code. The barrier to starting TDD has been lowered, and an environment has been created where it can be practiced much more easily than before.


Session Introduction

✋ This lecture is a recorded video of a live meetup held in July 2025, consisting of Part 1 presentation session and Part 2 Q&A session.

Part 1. Presentation Session

The presentation session covers the changing development environment with the emergence of LLMs. As AI takes on many aspects of coding, the role of human developers is also changing, but the limitation of LLM non-determinism remains an area that humans must still take responsibility for. Test code is presented as one of the important solutions to this challenge, and we discuss new development approaches that AI and TDD will create together.

Part 2. Q&A Session

In the Q&A session, questions and answers about whether TDD can be applied in various environments will follow.
Through this, we will take time to revisit the essence and purpose of TDD and think together about why and how it should be applied.

Want to learn the world of TDD more deeply?!

      I learned about testing and LLM utilization, and how testing actually becomes more important.

        It seems that coding with LLMs isn't quite easy in practical work yet. I'd also like to learn much more going forward. :)
