Use CodeLlama to Support Test-Driven Development

Contributor Name: Federico Castanedo

Difficulty level: Easy

Test-driven development (TDD) is a software development approach in which the developers write tests before the actual code. The main idea is to define the requirements and functionality of the code through tests. TDD is primarily used to create clean, bug-free code and improve the reliability of software.

In the following example I am using a TDD approach to develop code to sort a numeric or character array in an increasing order. We will use the CodeLlama-34-B-Instruct service from Perplexity Labs:

Prompt: I want to do test driven development.

Create the test code for the following input->output test examples in Python

Input: [0] ->Output: [0]

Input: [1, 0] ->Output: [0, 1]

Input: [1, 0, 2] ->Output: [0, 1, 2]

Input: [1, 3, 7, 5] ->Output: [1, 3, 5, 7]

Input: [A, B, Z, X] -> Output: [A, B, X, Z]

CodeLlama-34B-Instruct:

import unittest class TestSort(unittest.TestCase): def test_empty_list(self): self.assertEqual(sort([]), []) def test_single_element_list(self): self.assertEqual(sort([1]), [1]) def test_two_element_list(self): self.assertEqual(sort([1, 0]), [0, 1]) def test_three_element_list(self): self.assertEqual(sort([1, 0, 2]), [0, 1, 2]) def test_four_element_list(self): self.assertEqual(sort([1, 3, 7, 5]), [1, 3, 5, 7]) def test_string_list(self): self.assertEqual(sort(['A', 'B', 'Z', 'X']),['A', 'B', 'X','Z']) if __name__ == '__main__': unittest.main() ...
