Dataset Structure

from datasets import Dataset, load_dataset

# Load the dataset
dataset = load_dataset("Nutanix/cpp_unit_tests_benchmark_dataset")

# View dataset structure

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.
