Automation has become an essential tool for streamlining processes and improving efficiency. Playwright, a powerful automation framework, provides a robust platform for automating web applications. By combining Playwright with data-driven testing, we can create a framework that is accessible to non-technical users, allowing them to easily modify test data and automate their tasks.
This post explains the process of creating a data-driven Playwright framework that fetches data from an Excel sheet and executes tests based on the provided inputs. This framework will be designed to be user-friendly, with non-technical users able to modify the Excel sheet to drive the automation.
Setting Up the Environment
- Install Node.js and Create a New Project.
- Install Playwright ExcelJS (for reading Excel data) (npm install --save-dev playwright exceljs)
Creating the Excel Sheet
Create an Excel sheet named test_data.xlsx with the following columns:
Creating the Playwright Framework
Read Excel Data: Use ExcelJS to read data from the Excel sheet:
Execute Tests: Define your test logic based on the data in each row of the Excel sheet.
Running the Tests
Configure Playwright: In playwright.config.js file, specify browser options and other settings.
Run Tests: Use Playwright's CLI to run the tests:
npx playwright test
Parallel Execution:
To run tests in parallel, configure Playwright's workers option in the configuration file:
Additional improvements that we can do is,
Test Data Management: Use a database or other data management solution for larger datasets.
Test Reporting: Generate test reports to track test results and identify failures.
Data-Driven Parameters: Use data-driven parameters to dynamically pass values to your tests.
Conclusion:
By following these steps, we can create a powerful data-driven Playwright framework that empowers non-technical users to easily automate their testing tasks. This framework provides a flexible and scalable solution for automating web applications based on data-driven inputs.
