## 1. 📖 Overview |
|
|
|
|
|
[🤗 MIGRATION-BENCH](https://huggingface.co/collections/AmazonScience/migrationbench-68125452fc21a4564b92b6c3) |
|
|
is a large-scale code migration benchmark dataset at the **repository** level, |
|
|
across multiple programming languages. |
|
|
|
|
|
- Current and initial release includes `java 8` repositories with the `maven` build system, as of May 2025. |
|
|
|
|
|
|
|
|
## 2. Datasets |
|
|
|
|
|
There are three datasets in [🤗 MIGRATION-BENCH](https://huggingface.co/collections/AmazonScience/migrationbench-68125452fc21a4564b92b6c3): |
|
|
- All repositories included in the datasets are available on GitHub, under the `MIT` or `Apache-2.0` license. |
|
|
|
|
|
| Index | Dataset | Size | Notes | |
|
|
|-------|-----------------------------------------------|-------|-----------------------------------------------------------------------------------------------------| |
|
|
| 1 | [🤗 `AmazonScience/migration-bench-java-full`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-full) | 5,102 | Each repo has a test directory or at least one test case | |
|
|
| 2 | [🤗 `AmazonScience/migration-bench-java-selected`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-selected) | 300 | A **subset** of [🤗 `migration-bench-java-full`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-full) | |
|
|
| 3 | [🤗 `AmazonScience/migration-bench-java-utg`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-utg) | 4,814 | The unit test generation (utg) dataset, **disjoint** with [🤗 `migration-bench-java-full`](https://huggingface.co/datasets/AmazonScience/migration-bench-java-full)| |
|
|
|
|
|

|
|
## 3. Metadata |
|
|
|
|
|
Metadata is provided in the `csv` file for each dataset: |
|
|
|
|
|
1. `repo (str)`: The original repo URL without the `https://github.com/` prefix |
|
|
1. `base_commit (str)`: Base commit id |
|
|
- At this commit with `java 8` and `maven`, the repository is able to (1) compile and (2) pass existing unit tests and integration tests if any |
|
|
- It is the starting point for code migration from `java 8` |
|
|
1. `num_java_files (int)`: Number of `*.java` files in the repository at `base_commit`, similarly for all other `num_*` columns |
|
|
1. `num_loc (int)`: Lines of code for the repository |
|
|
1. `num_pom_xml (int)`: Number of modules (`pom.xml` files) in the repository |
|
|
1. `num_src_test_java_files (int)`: Number of `*.java` files in the dedicated `src/test/` directory |
|
|
1. `num_test_cases (int)`: Number of test cases, based on running the `mvn -f test .` command in the root directory |
|
|
- Non negative values indicate number of test cases is parsed correctly from the output |
|
|
- Negative values means it's unable to parse the output: `[INFO] Results:` (`-2`) or `[INFO] Tests run:` (`-1`) regex is missing |
|
|
1. `license (str)`: The license of the repository, either `MIT` or `Apache2.0` for the whole dataset |
|
|
|
|
|
### 3.1 Parsing Java Test Cases |
|
|
|
|
|
Here is a sample `maven -f test .` command output to get valid `num_test_cases`: |
|
|
|
|
|
``` |
|
|
... |
|
|
[INFO] Results: |
|
|
[INFO] |
|
|
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 |
|
|
... |
|
|
``` |
