Generating Test Reports with PyTest and Allure

 In automated testing, generating clear and informative test reports is essential for understanding test results, identifying failures, and communicating with stakeholders. PyTest, a powerful Python testing framework, can be integrated with Allure, a flexible reporting tool, to produce beautiful and detailed test reports.

Here's a step-by-step guide to generating test reports using PyTest and Allure.


What is Allure?

Allure is an open-source framework designed to create interactive and visually rich test reports. It shows test results in a readable format with:

  • Steps and logs
  • Screenshots
  • Attachments
  • Timelines and test history


Install Required Packages

Make sure Python and PyTest are installed, then install Allure-related packages:

pip install pytest allure-pytest

You also need to download Allure Commandline from the official site and add it to your system path.


Write Sample PyTest Script

Create a test file like test_sample.py:

import pytest

import allure

@allure.title("Test for addition")

@allure.description("Verify if 2 + 2 equals 4")

def test_addition():

    assert 2 + 2 == 4

@allure.title("Test for division")

@allure.description("Verify division by zero")

def test_divide_by_zero():

    with pytest.raises(ZeroDivisionError):

        result = 1 / 0


Run Tests and Generate Allure Results

Run your tests with the following command to generate results:

pytest --alluredir=allure-results

This creates a folder allure-results that stores raw data for the report.


Generate Allure Report

Now use the Allure CLI to generate the HTML report:

  • allure generate allure-results -o allure-report --clean
  • To open the report in a browser:
  • allure open allure-report

Report Features

Allure test reports provide:

Overview Dashboard – pass/fail stats, history, environment

Detailed Test Cases – with descriptions, logs, and screenshots

Timeline View – to analyze parallel test execution

Categories and Suites – organize tests for better readability


Conclusion

Combining PyTest with Allure helps testers produce clean, comprehensive, and interactive test reports. It improves visibility into test results and makes debugging much easier. If you're looking to enhance your test reporting in Python automation, Allure is a great choice to add to your workflow.

Understanding Tosca TestCases and Modules

 Tosca by Tricentis is a powerful model-based test automation tool widely used for functional and regression testing. One of its biggest strengths lies in its no-code approach to test creation, enabling testers to build robust automated tests without needing deep programming skills. At the heart of Tosca’s architecture are Modules and TestCases, two essential components that help in designing, executing, and maintaining automated tests efficiently. In this blog, we’ll explore what Tosca Modules and TestCases are, how they work, and how they contribute to effective test automation. What Are Tosca Modules? Modules in Tosca represent the building blocks of your test automation framework. They are reusable components that store the technical information about the UI elements (like buttons, fields, checkboxes) or APIs under test. Modules are created by scanning the application and capturing its elements. There are two types of modules: Standard Modules: These are created by scanning the...

How Tosca Handles TestData Parameterization

Tosca by Tricentis is a powerful test automation tool that provides robust support for test data parameterization, enabling reusable and maintainable test cases. Parameterization in Tosca allows testers to replace hardcoded values with dynamic data, making it easier to run the same test with multiple data sets. Here’s how Tosca handles test data parameterization: Using TestCase-Level Parameters You can define TestCase parameters to pass values dynamically into a test case. Steps: Right-click the TestCase and choose "Create TestCase Parameter". Assign a name (e.g., Username) and a default value. In your TestStep, reference the parameter using the syntax ={ParameterName}. Example: ={Username} You can override these parameters when calling the TestCase in another TestCase or in the TestCase folder. Using TestSheet/TestDataService (TDS) Tosca allows parameterization via TestSheets, a part of the Tosca TestCase Design module. This is the most scalable and maintainable way to manag...
