Importance of Testing in Code Development
Any code that has no tests is broken code. This statement underscores the critical importance of testing in software development. Without proper testing, code is prone to bugs, inefficiencies, and unexpected behaviors, which can lead to significant issues in production environments.
Evaluating LLM-Powered Applications
There are few skills more important than learning how to evaluate LLM-powered applications. While building an LLM demo is straightforward, every professional developer can attest to the challenges of creating production-grade systems that work reliably. This is where tools like DeepEval come into play.
Steps to Unit Test Your LLM-Powered Application
Here is how you can unit test your LLM-powered application (this works for agents, RAG, chatbots, anything):
- Install DeepEval using the command:
pip install deepeval - Write or generate a few LLM test cases
- Select the relevant metrics for testing
DeepEval is open source and can be found on GitHub. You can use it to benchmark your application’s performance against any criteria relevant to your use case. The library supports more than 14 research-backed metrics out of the box.
Generating Synthetic Test Data
One of the standout features of DeepEval is its ability to generate synthetic test data based on your knowledge base, thereby avoiding the need to write test cases manually. This is a significant time-saver and enhances the efficiency of the testing process.
Integration with Pytest
DeepEval integrates natively with Pytest, the most popular unit-testing library in the Python ecosystem. This integration allows you to use DeepEval in CI/CD pipelines, ensuring that your LLM-powered applications are thoroughly tested and reliable before deployment.
