Dataset Card for Open Source Code and Unit Tests
Dataset Details
Dataset Description
This dataset contains c++ code snippets and their corresponding ground truth unit tests collected from various open-source GitHub repositories. The primary purpose of this dataset is to aid in the development and evaluation of automated testing tools, code quality analysis, and LLM models for test generation.
- Curated by: Vaishnavi Bhargava
- Language(s): C++
Dataset Structure
from datasets import Dataset, load_dataset
# Load the dataset
dataset = load_dataset("Nutanix/cpp_unit_tests_benchmark_dataset")

DatasetDict({
train: Dataset({
features: ['ID', 'Language', 'Repository Name', 'File Name', 'File Path in Repository', 'File Path for Unit Test', 'Code', 'Unit Test - (Ground Truth)'],
num_rows: 2653
})
})
The dataset consists of the following columns:
ID: A unique identifier for each entry in the dataset. [Example: "0"]Language: The programming language of the file. [Example: "cpp"]Repository Name: The name of the GitHub repository, formatted as organisation/repository. [Example: "google/googletest"]File Name: The base name of the file (without extension) where the code or test is located. [Example: "sample1"]File Path in Repository: The relative path to the file within the GitHub repository. [Example: "googletest/samples/sample1.cc"]File Path for Unit Test: The relative path to the unit test file, if applicable. [Example: "googletest/samples/sample1_unittest.cc"]Code: The code content of the file, excluding any documentation or comments.Unit Test - (Ground Truth): The content of the unit test file that tests the code.
Dataset Sources
- Repository: The dataset is sourced from the following GitHub repositories: [Latest Commit before 2 July 24]
