Project description

BLogger — Pytest Logging Plugin

Full README.md available at GitHub


Overview

BLogger is a Pytest plugin for enhanced test logging and generating convenient and lightweight reports.
It supports structured test steps, descriptions, info notes, known bugs, and automatic screenshots.
Works seamlessly with Selenium WebDriver and Playwright Page instances.
Integrates with Allure and Qase for fewer duplicates like .steps, .attach etc.

Report Examples

Sample HTML reports and screenshots are available in the GitHub repository.


Installation

pip install pytest-b-logger

Setup

!!! Add blog.config.yaml file to the root of your project. !!!

project_name

Bare minimum for everything to work is project_name:

project_name: 'Project Name'

Can be changed later via CLI when running tests

pytest --blog-project-name '...'

timezone

Then you can set the desired Time Zone (IANA format e.g. Europe/Moscow, UTC, America/New_York).
The list of available timezones: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

project_name: 'Project Name'

tz: 'Europe/Moscow'

integrations

By default, integrations are turned off.
If you are using Allure and want steps, info, description etc. to be duplicated to Allure, simply add integrations block and set allure: True

project_name: 'Project Name'

tz: 'Europe/Moscow'

integrations:
  allure: True

hide_passwords

By default, passwords inside parameters are hidden.

If you want passwords to be shown simply set hide_passwords: False

project_name: 'Project Name'

tz: 'Europe/Moscow'

integrations:
  allure: True

hide_passwords: False

env and base_url

You can add env and base url here.

project_name: 'Project Name'

tz: 'Europe/Moscow'

integrations:
  allure: True

hide_passwords: True

env: 'prod' # optional
base_url: 'https://base-url.com' # optional

Which, could also be passed as command line options on test run, e.g. when using CI/CD:

pytest --blog-env 'prod' --blog-base-url 'https://base-url.com'

!!! Note !!! Options apply in the following order: blog.config.yaml > blog methods inside code > Command Line Arguments

Now you are all set up.
Simply run pytest and b_logs folder will be generated with blog_report.html and blog_summary.html
For more advanced usage please review BLogger API

BLogger API

Set Base URL

blog.set_base_url(base_url: str)

Set base_url for the entire Run

from b_logger import blog

blog.set_base_url('https://base-url.com')

Can also be added in blog.config.yaml:

base_url: 'https://base-url.com'

Or via command line options:

pytest --blog-base-url 'https://base-url.com'

Set Env

blog.set_env(env: str)

Set env for the entire Run

from b_logger import blog

blog.set_env('env')

Can also be added in blog.config.yaml:

env: 'prod'

Or via command line options:

pytest --blog_env 'prod'

Set Browser

set_browser(browser: "RemoteWebDriver | WebDriver | Page")

Set browser in a browser init fixture or in a test

If browser init fixture name is "driver", "page", "selenium_driver", "driver_init", "playwright_page" then it will be detected and applied automatically.
If browser is set it will also automatically make error screenshots on test fails and attach them to current step and error info.

import pytest
from selenium import webdriver
from b_logger import blog

@pytest.fixture()
def selenium_driver():
    driver = webdriver.Chrome()

    blog.set_browser(driver)  # <-- Manual browser instance setup

    yield driver

    driver.quit()

or

def test_playwright(page):  # <-- Will be detected automatically
    ...

Description

description(description: str)

Add Test Description
Will be added to the Overview Tab

Can be used as marker @blog.description() as well as function blog.description()
Usage inside a test expands description inside marker

from b_logger import blog

@blog.description(
    'Test with base functionality, '
    'this description can be modified inside the test'
)
def test_main_functionality():
    blog.description('This description will also be added')

Info

info(**kwargs)

Leave any important info or note about Test or Step
Will be added to the Overview Tab and Current Step

Can be used as marker @blog.info(k=v) as well as function blog.info(k=v)\

k is a name of an info block
v supports any data type, but {} is most readable and convenient

Any amount of info blocks is allowed: @blog.info(k=v, k=v, k=v, ...)

from b_logger import blog

@blog.info(
    meta={'platform': 'linux', 'python_version': 3.12},
    additional_parameters=['param 1', 'param 2'],
    some_info='some info'
)
def test_main_functionality():
    blog.info(a='a')
    
    with blog.step('Step 1'):
        blog.info(
            step_1_info={'b': 2, 'c': 3}
        )

Link

link(**kwargs)

Attach links to Test or Step
Will be added to the Overview Tab and Current Step

Can be used as marker @blog.link(k=v) as well as function blog.link(k=v)

k is a name of a link
v is a URL

Any amount of links is allowed: @blog.link(k=v, k=v, k=v, ...)

from b_logger import blog

@blog.link(
    first_link='http://aaa.com',
    second_link='http://bbb.com'
)
def test_main_functionality():
    blog.link(third_link='http://ccc.com')

Known Bug

known_bug(url: str, description: str)

Add known bug for Test or Step.
Will be added to the Overview Tab and Current Step

from b_logger import blog

@blog.known_bug(
    'https://link-to-your-bug/1.com',
    'Test Bug 1'
)
def test_main_functionality():
    blog.known_bug(description='Test Bug 2')

    with blog.step('Step Title'):
        blog.known_bug('https://link-to-your-bug/3.com')

Step

step(title: str, expected: str = None)

Wrap a code block into a Step.
Will be displayed in Setup, Steps and Teardown blocks depending on a test stage.

Info, Known Bugs, Links, Screenshots, Prints, Attachments will be added to a current step if made inside a step context.

from b_logger import blog

with blog.step('Step Title', 'Expected Result'):
    ...

Print

print(data)

Print any message (str, dict, list, object, etc.)
Will be added to a Current Step and stdout.txt

from b_logger import blog

data = {"a": 1, "b": 2}
blog.print(f'Some important data: {data}')

blog.print(f'Probably too long str\n'
            'can be newlined like that')

Screenshot

screenshot(name: str = None, is_error: bool = False)

Make screenshot

Will be added to the Attachments Tab and Current Step
Will do nothing if no browser is used

is_error flag adds "err_scr_" prefix to a scr name

from b_logger import blog

blog.screenshot('scr_name')
blog.screenshot('err_scr_name', True)

Attach

attach(content: Union[bytes, Path, BinaryIO, str, dict, list, int, float, bool, None], name: str = None)

Attach file or data
Will be added to the Attachments Tab and Current Step

Add extension to file name to save as a particular type. Example: 'excel_file.xlsx'

from b_logger import blog
from pathlib import Path

blog.attach({"a": 1, "b": 2}, 'some_data')
blog.attach(Path('path/to/your/file.ext'))
blog.attach(excel_data, 'excel_file.xlsx')

Usage examples

Publishing to CI/CD

Jenkins

To post results to Jenkins you could simply use the HTMLpublisher utility and the following command:

publishHTML([
    reportName: 'BLog Report',
    reportDir: 'b_logs',
    reportFiles: 'blog_report.html',
    icon: 'static/icon.svg',
    allowMissing: false,
    keepAll: true,
    alwaysLinkToLastBuild: true
])

However, you may face the problem of CSP (Content Security Policy) blocking .js and .css.
In order not to affect CSP you can set up Resource Root URL: https://www.jenkins.io/doc/book/security/user-content/#resource-root-url

BLog Report then will be available via https://jenkins.../job/.../BLog_20Report/

Also, you can store b_logs as artifact for the build:

archiveArtifacts artifacts: 'b_logs/**', fingerprint: true, allowEmptyArchive: true
zip zipFile: 'b_logs.zip', archive: true, dir: 'b_logs/'

Useful Features

Notes

Add blog.notes.yaml to the root of your project

You can add style block if you want notes to be formatted in blog_summary.html.
Inside simple css styles like color and font-size

style: # optional
  color: red
  font-size: 20px

notes:
  - 'Here you can add any useful info about project'
  - 'For example floating bugs or specifications'
