Introduction
There are many pushbacks when we want to introduce TDD in a new environment. People are pessimistic, conservative or just simply have negative experiences with applying TDD. Therefore convincing others to use TDD can be challenging. But fortunately, TDD has some superior characteristics which can help you to reason about the importance of applying TDD.
Convince the management to apply TDD
What our management and boss ultimately want is to deliver value to the customer. Shipping quality and bug-free products. They don’t care how many times you refactor, or whether you use TDD or any other technique. They care about the result, and not the process.
But the good thing is that TDD helps with all of the things that they want. By doing TDD we produce code where the number of bugs are minimized and the quality is maximized. By having a well-tested product we increase agility and speed while we reduce the time to market. All in all, TDD increases reputation and saves time and money in the long run.
Convince your fellow colleagues to use TDD
As responsible developers, we want to write code in the best possible way. We strive for producing bugless, useful and well-tested code while we want to spend the least amount of time on time-consuming activities such as debugging.
TDD has some superior characteristics which can not be achieved with TLD, such as:
Introducing trust in our test suite by seeing our tests failing which verifies that the tests are meaningful and unique
Efficiently producing test assertions for every path of the business logic, resulting in high mutation score and a strong safety net
Building the quality into the product during the development process as we can’t inspect quality after the fact
Preventing Geek-at-keyboard (GAK) activities such as debugging
Conclusion
TDD won't solve all of your problems. But it will prevent many of them. It is not about going much faster. It is about going much better. TDD is not a silver bullet. But it is a magnificent tool, with many unique selling points.
