Test-driven development (TDD) is a software development approach where you write tests for your code before you actually write the code itself. This helps ensure that your code works correctly from the very beginning. Here’s how it works in simple steps:
Let’s say you’re building a simple calculator that can add two numbers.
1,Write a Test: First, you write a test to check if the add function works.
def test_add():
assert add(2, 3) == 5This test checks if adding 2 and 3 gives you 5. Since you haven’t written the add function yet, this test will fail.
2.Write the Code: Now, you write the add function to pass the test.
def add(a, b):
return a + b
3.Run the Test: Run the test to see if it passes.
test_add() # This should pass4.Repeat: Next, you could write a test for another function, like subtraction, and go through the same steps.
This cycle helps ensure your code works correctly and makes it easier to find and fix bugs early in the development process.
Test-driven development (TDD) benefits include better code quality, clear documentation, confident refactoring, faster debugging, modular development, improved design, stakeholder confidence, team collaboration, predictability, regression prevention, easier onboarding, and long-term cost savings.
