Test-Driven Development (TDD) is a software development approach in which tests are written before the code. It's a valuable method that can lead to cleaner, more reliable software. However, like any approach, it has potential pitfalls. Here are a few:

1. **Time-consuming**: Writing tests before the code can be time-consuming. This can slow down the development process, especially in the early stages.

2. **Requires expertise**: TDD requires a certain level of expertise to be done effectively. Developers need to understand how to write good tests, which can be a challenge for those new to the practice.

3. **False sense of security**: Passing tests can give a false sense of security. Just because all tests pass doesn't mean the software is bug-free. Tests are only as good as their design and implementation.

4. **Maintenance**: As the codebase grows, maintaining all the tests can become a daunting task. This can lead to outdated tests that no longer accurately reflect the code they're supposed to be testing.

5. **Inflexibility**: TDD can be inflexible. It requires developers to stick to a rigid process of writing tests first, which can stifle creativity and limit the exploration of alternative solutions.

6. **Overemphasis on testing**: TDD can lead to an overemphasis on testing at the expense of other important aspects of software development, such as design and architecture.

In conclusion, while TDD has many benefits, it's important to be aware of these potential pitfalls and to use the approach judiciously.
