What are some examples of deterministic tests?

Deterministic tests are tests that produce the same output given the same input. For example, a function that adds two numbers will always return the same result for the same inputs.

Can you give me a specific code example?

Sure! Here's a simple example in Python:

def add(a, b):
    return a + b

assert add(2, 3) == 5  # This is a deterministic test

What about non-deterministic tests?

Non-deterministic tests can yield different results even with the same input, often due to external factors like random number generation or time-based functions.

How can I ensure my tests are deterministic?

To ensure tests are deterministic, avoid using random values, external APIs, or any state that can change between test runs.
