Python Test Frameworks

Note

Taken from Pytestomatio Reporter Readme

testomat.io plugin for pytest

uses testomat.io API:

• https://testomatio.github.io/check-tests/
• https://testomatio.github.io/reporter/

Installation

pip install pytestomatio

Usage

Synchronize tests to testomat.io and get back test id. Tests will not be executed

pytest --testomatio sync

Remove all test ids from source code. Tests will not be executed

pytest --testomatio remove

Run pytest and send test results into testomat.io.
Test can be sent to testomat.io without ids in your test code. If testomat.io failed to match tests by title, it will create new tests for the run

pytest --testomatio report

Run pytest with debug parameter to get test data collected in metadata.json file

pytest --testomatio debug

Configuration with environment variables

You can use environment variable to control certain features of testomat.io

Env variable	What it does	Examples
TESTOMATIO	Provides token for pytestomatio to access and push data to testomat.io	TESTOMATIO=tstmt_***** pytest —testomatio sync
TESTOMATIO_RUN	Name of a test run to create on testomat.io	TESTOMATIO_RUN=“Smoke test” pytest —testomatio report
TESTOMATIO_RUN_ID	Id of existing test run to use for sending test results to	TESTOMATIO_RUN_ID=98dfas0 pytest —testomatio report
TESTOMATIO_RUNGROUP_TITLE	Create a group (folder) for a test run	TESTOMATIO_RUNGROUP_TITLE=“Release 2.0” pytest —testomatio report
TESTOMATIO_ENV	Assign environment to a test run	TESTOMATIO_ENV=“linux,chrome,1920x1080” pytest —testomatio report
TESTOMATIO_LABELS	Assign labels to a test run	TESTOMATIO_ENV=“smoke,regression” pytest —testomatio report
TESTOMATIO_SYNC_LABELS	Assign labels to a test case when you synchronise test from code with testomat.io	TESTOMATIO_SYNC_LABELS=“number:1,list:one,standalone” pytest —testomatio report
TESTOMATIO_CODE_STYLE	If you are not sure, don’t set this variable. Default value is ‘default’	TESTOMATIO_CODE_STYLE=pep8 pytest —testomatio sync
TESTOMATIO_CI_DOWNSTREAM	If set, pytestomatio will not set or update build url for a test run. This is useful in scenarios where build url is already set in the test run by Testomat.io for test runs that a created directly on Testomat.io.	TESTOMATIO_CI_DOWNSTREAM=true pytest —testomatio report

Run groups parameter

There is environment variable TESTOMATIO_RUNGROUP_TITLE that can be used to specify run tests with specific group title.

pytest.ini

In case you are using private testomat.io service, create pytest.ini file in your project root directory. Specify testomat.io url in it

[pytest]
testomatio_url = https://app.testomat.io

Submitting Test Run Environment

to configure test environment, you can use additional option:

pytest --testomatio report --testRunEnv "windows11,chrome,1920x1080"

Environment values are comma separated, please use double quotation.

Submitting Test Artifacts

testomat.io does not store any screenshots, logs or other artifacts.

In order to manage them it is advised to use S3 Buckets (GCP Storage). https://docs.testomat.io/usage/test-artifacts/

Analyser needs to be aware of the cloud storage credentials. There are two options:

1. Enable Share credentials with testomat.io Reporter option in testomat.io Settings -> Artifacts.
2. Use environment variables ACCESS_KEY_ID, SECRET_ACCESS_KEY, ENDPOINT, BUCKET, BUCKET_PATH

You would need to decide when you want to upload your test artifacts to cloud storage

1. Upload page screenshot when test fails, using fixtures reference

# content of conftest.py
import pytest
import random
import os
from typing import Dict
from pytest import StashKey, CollectReport
from playwright.sync_api import Page

phase_report_key = StashKey[Dict[str, CollectReport]]()

@pytest.hookimpl(wrapper=True, tryfirst=True)
def pytest_runtest_makereport(item, call):
    rep = yield
    item.stash.setdefault(phase_report_key, {})[rep.when] = rep
    return rep


@pytest.fixture(scope="function")
def handle_artifacts(page: Page, request):
    yield
    report = request.node.stash[phase_report_key]
    if ("call" not in report) or report["setup"].failed or report["call"].failed:
        random_string = ''.join(random.choices(string.ascii_letters + string.digits, k=8))

        filename = f"{random_string}.png"
        screenshot_path = os.path.join(artifacts_dir, filename)
        page.screenshot(path=screenshot_path)
        # file_path - required, path to file to be uploaded
        # file_bytes - required, bytes of the file to be uploaded
        # key - required, file name in the s3 bucket
        # bucket_name - optional,name of the bucket to upload file to. Default value is taken from testomat.io
        artifact_url = pytest.testomatio.upload_file(screenshot_path, filename)
        # or
        # artifact_url = pytest.testomatio.upload_file_object(file_bytes, key, bucket_name)
        pytest.testomatio.add_artifacts(request.node, [artifact_url])
    page.close()

⚠️ Please take into account s3_connector available only after pytest_collection_modifyitems() hook is executed.

2. If you prefer to use pytest hooks - add pytest_runtest_makereport hook in your conftest.py file.

def pytest_runtest_makereport(item, call):
    artifact_url = pytest.testomatio.upload_file(screenshot_path, filename)
    pytest.testomatio.add_artifacts([artifact_url])

Clarifications

• tests can be synced even without @patest.mark.testomatio('@T96c700e6') decorator.
• test title in testomat.io == test name in pytest
• test suit title in testomat.io == test file name in pytest

Example of test

To make the experience more consistent, it uses standard pytest markers.
testomat.io test id is a string value that starts with @T and has 8 symbols after.

from pytest import mark


@mark.testomatio('@T96c700e6')
def test_example():
    assert 2 + 2 == 4

Test

• import into empty project
• updated test - (resync)
• test run
• test run into a folder
• test run labels, tags

TODO

• retry test run update with less attributes, we get 500 from api
• handler non configured s3 bucket error
• Fix test duration
