Editing Test-driven development (section)

=== Disadvantages ===

However, TDD is not without its drawbacks:

# '''Increased Code Volume''': Implementing TDD can result in a larger codebase as tests add to the total amount of code written.
# '''False Security from Tests''': A large number of passing tests can sometimes give a misleading sense of security regarding the code's robustness.<ref>{{Cite journal |last1=Parsa |first1=Saeed |last2=Zakeri-Nasrabadi |first2=Morteza |last3=Turhan |first3=Burak |date=2025-01-01 |title=Testability-driven development: An improvement to the TDD efficiency |url=https://www.sciencedirect.com/science/article/pii/S0920548924000461 |journal=Computer Standards & Interfaces |volume=91 |pages=103877 |doi=10.1016/j.csi.2024.103877 |issn=0920-5489}}</ref>
# '''Maintenance Overheads''': Maintaining a large suite of tests can add overhead to the development process.
# '''Time-Consuming Test Processes''': Writing and maintaining tests can be time-consuming.
# '''Testing Environment Set-Up''': TDD requires setting up and maintaining a suitable testing environment.
# '''Learning Curve''': It takes time and effort to become proficient in TDD practices.
# '''Overcomplication''': An overemphasis on TDD can lead to code that is more complex than necessary.
# '''Neglect of Overall Design''': Focusing too narrowly on passing tests can sometimes lead to neglect of the bigger picture in software design.
# '''Increased Costs''': The additional time and resources required for TDD can result in higher development costs.
