Streamlining Sanity Testing with Playwright Automation

Introduction

Automation has become a crucial asset for ensuring software quality, especially during critical stages such as production deployment. In this blog post, we explain how our company harnessed the power of Playwright automation to enhance sanity testing in a significant client project. We achieved improved efficiency, accuracy, and overall software quality by automating sanity test cases and integrating them into the pre-production deployment pipeline.

The Power of Playwright Automation

Playwright is a modern and versatile automation framework. Its robust capabilities allowed us to simulate user interactions, perform browser automation, and validate expected behaviors across multiple web applications. Playwright’s support for various browser engines and programming languages ensured flexibility and adaptability in our automation efforts.

Key Features of Playwright

Playwright comes with a variety of features. Here are some of them:

  • Multi-browser Support: Playwright’s unique selling point lies in its capability to work across multiple browsers, ensuring maximum test coverage and browser compatibility.
  • Headless and Headful Mode: Playwright allows tests to be executed in both headless and headful modes, providing flexibility in running tests locally or in a headless environment.
  • Cross-browser Parallel Testing: With Playwright, you can parallelize your tests across multiple browsers, significantly reducing test execution time.
  • Rich Element Interaction: Playwright offers intuitive APIs for handling complex scenarios such as interacting with iframes, pop-ups, and shadow DOM elements.
  • Network Interception and Mocking: Testers can intercept and mock network requests, enabling them to simulate various server responses and test application behavior under different network conditions.
  • Playwright Test Runner: The built-in test runner in Playwright offers seamless test execution and powerful reporting capabilities, making it easy to analyze test results.
Integrating Sanity Testing into the Deployment Pipeline

The project demanded a robust and streamlined approach to quality assurance. Given the project’s complexity and importance, a comprehensive sanity testing process was essential to catch potential regressions and issues before they reached production. To ensure the highest quality standards, we integrated automated sanity tests into the pre-production deployment pipeline. This strategic move allowed us to identify and rectify potential issues at an early stage, significantly reducing the risk of defects reaching the end users.

Creating Sanity Test Cases

We meticulously crafted a suite of sanity test cases tailored to the unique functionalities and features of the project. Each test case simulated real-world user interactions, validating critical workflows, data integrity, and user interface components.

Benefits and Outcomes

The implementation of Playwright automation for sanity testing yielded several remarkable benefits:

  • Enhanced Efficiency: Automated sanity tests executed rapidly, enabling quick feedback on code changes, and ensuring a swift development lifecycle.
  • Reduced Human Error: Automated tests are consistently executed without human intervention, minimizing the risk of human errors that can occur during manual testing.
  • Regression Detection: By repeatedly running sanity tests, we caught subtle regressions and integration issues that might have gone unnoticed through manual testing alone.
  • Early Issue Identification: Defects and issues were identified and addressed during the development phase, significantly reducing the cost and effort associated with fixing them post-production.
Lessons Learnt and Future Prospects

The success of Playwright automation for sanity testing in our client project demonstrates the potential of automation in ensuring software quality. As we move forward, we are exploring opportunities to expand the application of Playwright to other projects, optimizing our testing processes and accelerating development cycles.

Integration with Azure DevOps

Azure DevOps is a popular DevOps platform that provides robust capabilities for source control, build automation, release management, and more. Integrating Playwright into the Azure DevOps pipeline enhances the automation process and streamlines the end-to-end software development lifecycle.

Steps for Integration
  • Version Control: Ensure that your Playwright tests are properly version-controlled using a Git repository. This allows you to track changes, collaborate with team members, and ensure consistency in test scripts.
  • Build and Test Script: In your Azure DevOps pipeline, set up a build script to install dependencies including Playwright, and execute the tests. This step ensures that your tests are run automatically whenever there is a code commit or pull request.
  • Parallel Execution: Leverage Playwright’s built-in parallel execution capabilities to distribute your tests across multiple agents in Azure DevOps. This reduces the overall test execution time, enabling quicker feedback on code changes.
  • Test Reporting: Integrate Playwright’s test runner with Azure DevOps’ reporting and analytics tools. This allows you to generate comprehensive test reports, track test results, and analyze test trends over time.
  • Continuous Integration: Set up continuous integration triggers in Azure DevOps to automatically run your Playwright tests on each code push, ensuring immediate feedback on potential issues.
  • Integration with Azure Pipelines: Use Azure pipelines to deploy and execute your Playwright tests on various environments including staging and production. This ensures that your tests are run against the application in real-world scenarios.
  Benefits of Playwright-Azure DevOps Integration
  • Increased Test Coverage: Playwright’s multi-browser support combined with parallel execution, enables teams to achieve higher test coverage, identifying browser-specific issues early in the development cycle.
  • Quick Feedback Loop: The integration allows developers to receive rapid feedback on their code changes, facilitating quicker bug detection and resolution.
  • Consistency and Reliability: Playwright’s robustness ensures stable test execution, contributing to more reliable test results and increased confidence in the application’s quality.
  • Cost and Time Savings: Automated testing with Playwright reduces the need for manual testing efforts, leading to cost and time savings in the long run.Related articles:
