Allure Behave

Allure Behave pypi latest version

Generate beautiful HTML reports using Allure Report and your behave tests.

Allure Report Behave 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 Behave adapter.

    Bash
    pip install allure-behave
  5. In the Behave configuration file (such as .behaverc or behave.ini), specify the Allure Behave as the output formatter and specify the path to the test results directory.

    For example:

    INI
    [behave] format=allure_behave.formatter:AllureFormatter outfiles=allure-results

2. Run tests

Run your behave tests the same way as you would run them usually. For example:

Bash
python -m behave

This will save necessary data into allure-results or other directory, according to the outfile option. 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.

Writing tests

The Allure Behave adapter extends the standard reporting features of behave by providing additional capabilities for crafting more informative and structured tests. This section highlights key enhancements that can be utilized:

In most cases, you need to indicate to Allure Behave that a certain property needs to be assigned to the test result. Most properties can be assigned via Gherkin tags or via the Runtime API.

  • Gherkin tags: use Gherkin tags to assign various data to a particular Scenario or a whole Feature. Note that due to a limitation in the Gherkin syntax, a tag cannot contain spaces.

    When using this approach, the data is guaranteed to be added to the test result regardless of how the test itself runs.

  • Runtime API: use Allure's functions to add data to the test result during the execution of its steps. This approach allows for constructing the data dynamically.

    Note that it is recommended to call the Allure's functions as close to the beginning of the test as possible. This way, the data will be added even if the test fails early.

There is a lot of metadata you can add to each test so that it would appear in the report. See reference for more details.

Gherkin
Feature: Labels @critical @allure.label.owner:JohnDoe @allure.link:https://dev.example.com/ @allure.issue:UI-123 @allure.tms:TMS-456 Scenario: Create new label for authorized user When I open labels page And I create label with title "hello" Then I should see label with title "hello"
Python
import allure from behave import then @then('I open labels page') def step_impl(context): allure.dynamic.link('https://dev.example.com/', name='Website') allure.dynamic.issue('UI-123') allure.dynamic.testcase('TMS-456') ...

Organize tests

As described in Improving navigation in your test report, Allure supports multiple ways to organize tests into hierarchical structures. Allure Behave provides functions to assign the relevant fields to tests either by adding decorators or “dynamically” (same as for the metadata fields).

To specify a test's location in the behavior-based hierarchy:

Gherkin
@allure.label.epic:WebInterface Feature: Labels @allure.label.story:Labels Scenario: Create new label for authorized user When I open labels page And I create label with title "hello" Then I should see label with title "hello"

To specify a test's location in the suite-based hierarchy:

Gherkin
Feature: Labels @allure.label.parentSuite:WebInterface @allure.label.suite:EssentialFeatures @allure.label.subSuite:Labels Scenario: Create new label for authorized user When I open labels page And I create label with title "hello" Then I should see label with title "hello"

To specify a test's location in the package-based hierarchy:

Gherkin
Feature: Labels @allure.label.package:org.example @allure.label.testClass:TestMyWebsite @allure.label.testMethod:TestLabels() Scenario: Create new label for authorized user When I open labels page And I create label with title "hello" Then I should see label with title "hello"

Divide a test into steps

Allure Behave provides two ways of creating steps and sub-steps: “decorated steps” and “context steps”, see reference.

Python
import allure from behave import then @then("I open labels page") def step_impl(context): step1() for val in ["val1", "val2", "val3"]: step2(val) @allure.step("Step 1") def step1(): ... @allure.step("Step 2 (with value {val})") def step2(val): ...
Python
import allure from behave import then @then("I open labels page") def step_impl(context): with allure.step("Step 1"): ... for val in ["val1", "val2", "val3"]: with allure.step(f"Step 2 (with value {val})"): ...

Describe parametrized tests

Allure Behave can display parameters passed to the tests via Examples tables, see 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 Behave provides various ways to create an attachment, both from existing files or generated dynamically, see reference.

Python
import allure from behave import then @then("I open labels page") def step_impl(context): ... with open('/path/to/image.png', 'rb') as png_file: png_bytes = png_file.read() allure.attach(png_bytes, name="img", attachment_type=allure.attachment_type.PNG)

Select tests via a test plan file

If the ALLURE_TESTPLAN_PATH environment variable is defined and points to an existing file, behave will only run tests listed in this file.

Here's an example of running tests according to a file named testplan.json:

Bash
export ALLURE_TESTPLAN_PATH=testplan.json python -m behave
powershell
$Env:ALLURE_TESTPLAN_PATH = "testplan.json" python -m behave

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.
