Running Multiple Test Cases from a CSV File Using Playwright and TypeScript.

In the world of automated testing, maintaining flexibility and scalability is crucial—especially when it comes to validating functionality across multiple data inputs. Data-driven testing enables QA professionals to decouple test scripts from the input data, allowing the same test flow to run with multiple sets of inputs.

This tutorial explains how to set up data-driven tests in Playwright using TypeScript, where external CSV files provide varying input data for each scenario.

This approach is highly effective for validating login scenarios, form submissions, and any functionality that depends on multiple sets of data.

Why Use Data-Driven Testing?

Data-driven testing provides several benefits:

• Reduced Code Duplication: Instead of writing multiple similar tests, a single test reads various inputs from an external file.
• Improved Maintainability: Test data can be modified independently of the test logic.
• Scalability: Enables easier scaling of testing across a wide range of input combinations.
