pytest-data-extractor

Pytest plugin intended for extracting test data and metadata and serializing it into a file. The plugin currently support json files.

This is a completely open source project so everyone are more than welcome to join and extended it.

Version 0.1.7

Use case

pip install the package to your project's virtual environment. Directly from plugin folder:

pip install -e .

or pip install it from Pypi:

pip install pytest-data-extractor

Go to a test file and now simply add upload_manager fixture in order to save a variable (except callable), Like so:

# test_foo.py

def test_bar(upload_manager):
    expected_value = upload_manager(1000)
    assert expected_value == 1000, "assert failed"

Activate the plugin with the pytest cli with the command:

pytest --output_test_data True

Now the data passed to upload_manager, as well as the test data that is specified at the TestData container will be stored in an external file. For a json file output:

[
  {
        "test_input": [
            {
                "test_file_path": "_20220719_21_00_10_806534.csv",
                "file_type": "csv"
            }
        ],
        "expected_result": null,
        "actual_result": null,
        "test_operator": null,
        "test_func": "test_bar",
        "test_status": 1,
        "test_duration": 0.046707000000000054,
        "meta_data": null
    }
]

In version 0.1.7 there's no recording of the expected_result, actual_result and test_operator since the test result is a PASS. Additionally, all objects passed to the upload_manager fixture will be saved as an external file that will be associated by test_file_path param. There's no garbage collection so be mindful how and where the files are stored.

* left- actual result.
* right- expected result.
