  TestEval-LR is a benchmark dataset for evaluating unit test generation capabilities of models on low-resource programming languages (Rust, Go, and Julia). Each sample provides a focal function's source code and metadata for generating idiomatic test code.

# 📚 TestEval-LR: Unit Test Generation Benchmark for Low-Resource Languages

TestEval-LR is a **validation benchmark** designed to measure how well models can generate unit tests for **Low-Resource Programming Languages (LRPLs)** — specifically **Rust**, **Go**, and **Julia**.

## 📌 Purpose
Evaluate how well a model can generate test code, given a focal function's source code and context.

## 📂 Dataset Structure
Each example contains:
- **function_name**: Name of the focal function.
- **focal_code**: Raw source code of the function (used for context).
- **function_component**: Detail information about the function like function signature,arguments definition,line range,...  
- **file_content**: Content of file have the focal function.  
- **file_path**: Relative path to the file in the repository.  



### Dataset Size
The dataset contains **~372–412 samples** per language, depending on the source repository.

## 📝 Prompt Example for Test Generation

**Suffix syntax for each language:**
suffix syntax is to put in the end of the prompt ( after wrap in the chat template if need ) to generate the expected test function and avoid hallucination 
```plaintext
    "Rust":  "#[test]\nfn test_{function_name}() {"

    "Julia": "@testset \"{function_name} Tests\" begin"

    "Go":    "func Test{function_name_with_uppercase_first_letter}("
```
This dataset uses a structured prompt format for three programming languages: **Rust**, **Julia**, and **Go**.  
Each language has two variants:

- **`instruct`** → Full instruction prompt including explicit guidance to generate a unit test for a given function.
- **`base`** → Minimal version that only contains the function code and a short comment reminding to check correctness.

### Structure

```python
prompts = {
    "Rust": {
        "instruct": (
            "{function_code}\n"
            "Generate Rust unittest for {function_name} function in module {file_path}:\n"
        ),
        "base": (
            "{function_code}\n"
            "// Check the correctness for {function_name} function in Rust\n"
        ),
    },
    "Julia": {
        "instruct": (
            "{function_code}\n"
            "Generate Julia unittest for {function_name} function in module {file_path}:\n"
        ),
        "base": (
            "{function_code}\n"
            "# Check the correctness for {function_name} function in Julia\n"
        ),
    },
    "Go": {
        "instruct": (
            "{function_code}\n"
            "Generate Go unittest for {function_name} function in module {file_path}:\n"
        ),
        "base": (
            "{function_code}\n"
            "// Check the correctness for {function_name} function in Go\n"
        ),
    },
}
