How to set disableSameOriginPolicy to true for the happy-dom environment?

[FSou1]

We have a unit test that is failing within the following lines:

happy-dom/packages/happy-dom/src/fetch/Fetch.ts

Lines 217 to 232 in cf74f5f

	if (!this.disableSameOriginPolicy) {
	const compliesWithCrossOriginPolicy = await this.compliesWithCrossOriginPolicy();
	if (!compliesWithCrossOriginPolicy) {
	this.#browserFrame.page.console.warn(
	`Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at "${this.request.url}".`
	);
	throw new this.#window.DOMException(
	`Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at "${this.request.url}".`,
	DOMExceptionNameEnum.networkError
	);
	}
	}
	return await this.sendRequest();
	}

So apparently, we want to set disableSameOriginPolicy: true for the happy-dom environment with the vitest.

Is there a way to set it up without using the Global Registrator?

This is how you do it for Vitest:

export default defineConfig({
  test: {
    environment: 'happy-dom',
    environmentOptions: {
      happyDOM: {
        settings: {
          fetch: {
            disableSameOriginPolicy: true
          }
        }
      }
    }
  }

You can read more about the various settings in the API Documentation.
