Allure Pytest-BDD

Allure Pytest-BDD pypi latest version

Generate beautiful HTML reports using Allure Report and your Pytest-BDD tests.

Allure Report Pytest-BDD Example

How to start

1. Prepare your project

  1. Install the Allure Report command-line tool, if it is not yet installed in your operating system. Note that Allure Report requires Java, see Installation.

  2. Open a terminal and go to the project directory. For example:

    Bash
    cd /home/user/myproject
  3. If necessary for your system configuration, activate the virtual Python environment for your project.

    For example, if the project uses a venv environment, the command to activate it may look like this:

    Bash
    source .venv/bin/activate

    This step is not necessary if you are using the system Python environment.

  4. Install the Allure Pytest-BDD adapter.

    Bash
    pip install allure-pytest-bdd

2. Run tests

When running your tests, specify a path for the test results directory in the --alluredir command-line argument. For example:

Bash
python -m pytest --alluredir allure-results

This will save necessary data into the test results directory. If the directory already exists, the new files will be added to the existing ones, so that a future report will be based on them all.

3. Generate a report

Finally, convert the test results into an HTML report. This can be done by one of two commands:

  • allure generate processes the test results and saves an HTML report into the allure-report directory. To view the report, use the allure open command.

    Use this command if you need to save the report for future reference or for sharing it with colleagues.

  • allure serve creates the same report as allure generate but puts it into a temporary directory and starts a local web server configured to show this directory's contents. The command then automatically opens the main page of the report in a web browser.

    Use this command if you need to view the report for yourself and do not need to save it.

Describe parametrized tests

Allure Pytest-BDD can display parameters passed to the tests via Examples tables, see the reference.

Gherkin
Feature: User management Scenario Outline: Registration When I go to the registration form And I enter my details: <login>, <password>, <name>, <birthday> Then the profile should be created Examples: | login | password | name | birthday | | johndoe | qwerty | John Doe | 1970-01-01 | | janedoe | 123456 | Jane Doe | 1111-11-11 |

Attach screenshots and other files

You can attach any sorts of files to your Allure report. For example, a popular way to make a report easier to understand is to attach a screenshot of the user interface at a certain point.

Allure Pytest-BDD provides various ways to create an attachment, both from existing files or generated dynamically, see the reference.

Python
import allure import requests from pytest_bdd import then @then("I open labels page") def test_labels(): ... png_bytes = requests.get('https://example.com/image.png').content allure.attach(png_bytes, name="my-image", attachment_type=allure.attachment_type.PNG) allure.attach.file('/path/to/image.png', name="my-image", attachment_type=allure.attachment_type.PNG)

Environment information

For the main page of the report, you can collect various information about the environment in which the tests were executed.

For example, it is a good idea to use this to remember the OS version and Python version. This may help the future reader investigate bugs that are reproducible only in some environments.

Allure Report Environments Widget

To provide environment information, put a file named environment.properties into the allure-results directory after running the tests. See the example in Environment file.

Note that this feature should be used for properties that do not change for all tests in the report. If you have properties that can be different for different tests, consider using Parametrized tests.
