Does Playwright Test support globalThis? (TypeScript/JavaScript)
When working with Playwright Test, you may come across the need to access the globalThis
object. The globalThis
object provides a way to access the global scope, regardless of the environment (browser or Node.js). However, due to the differences in how Playwright Test runs tests, there are some considerations to keep in mind.
By default, Playwright Test runs tests in a browser context using the Playwright library. In this context, the globalThis
object is not available. If you try to access it directly, you will encounter an error.
However, there are a couple of workarounds to access the globalThis
object in Playwright Test:
1. Using the window
object
In a browser context, you can access the globalThis
object through the window
object. The window
object represents the global scope in a browser environment.
// TypeScript
const globalThisObject = (window as any).globalThis;
// JavaScript
const globalThisObject = window.globalThis;
This code snippet demonstrates how to access the globalThis
object using the window
object. By casting window
as any
in TypeScript, you can access the globalThis
property.
2. Using the global
object in Node.js
In a Node.js context, you can access the globalThis
object through the global
object. The global
object represents the global scope in a Node.js environment.
// TypeScript/JavaScript
const globalThisObject = global.globalThis;
This code snippet demonstrates how to access the globalThis
object using the global
object in Node.js. You can directly access the globalThis
property.
It’s important to note that the availability of the globalThis
object may vary depending on the version of Playwright Test and the environment you are running your tests in. Always refer to the Playwright Test documentation and the specific environment requirements for the most up-to-date information.
In conclusion, while Playwright Test does not directly support the globalThis
object, you can still access it using the window
object in a browser context or the global
object in a Node.js context. These workarounds allow you to access the global scope and utilize the globalThis
object as needed in your Playwright Test scripts.
