How do I write effective unit tests for my code?

To write effective unit tests, start by identifying the smallest testable parts of your code, usually functions or methods.

What tools can I use for writing unit tests?

Popular tools include JUnit for Java, NUnit for .NET, and pytest for Python. Choose one based on your programming language.

How do I structure my unit tests?

Structure your tests with clear naming conventions, and use setup and teardown methods to prepare and clean up your test environment.

Can you give me an example of a unit test?

Sure! Here's a simple example in Python using pytest:

    return a + b

def test_add():
    assert add(2, 3) == 5
