TestCodeo - GoCodeo's fine-tuned Language Model dedicated to Python unit test generation.

### Approach
Our team curated a unique dataset of 200,000 prompt-completion pairs in alpaca format, specifically designed for Python unit test generation.

### Two-Stage Finetuning Process
Stage 1: We fine-tuned the base Codellama 7B Python model with 25k easy and 75k medium instructions.

Stage 2: The resulting Test-Codeo-Base was further refined with the remaining medium-hard questions to develop TestCodeo.

### Evaluation Methodology
Utilizing OpenAI's human eval dataset, we generated test cases for 164 coding instructions and measured code coverage.

### Results
TestCodeo achieved an impressive 89% code coverage, surpassing Codellama's 17% and approaching GPT-3.5-turbo's 93%.
