- **Use Case**: Automated unit test generation for software engineering
- **Framework**: R2E-Gym ecosystem

## Usage

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "r2e-gym/R2E-TestgenAgent"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Use with R2E-Gym framework for best results
from r2egym.agenthub.agent.agent import Agent, AgentArgs
agent_args = AgentArgs.from_yaml("testing_agent_config.yaml")
agent = Agent(name="TestingAgent", args=agent_args)
```

## Training
