How to fix TS2339: Property 'browser' does not exist on type 'Global'?

Dear jest-puppeteer community,

I am using typescript and configured jest-puppeteer using next configuration: (without configuring custom setup and teardown)

jest-puppeteer.config.js

module.exports = {
    launch: {
        headless: false,
    }
}

jest.breakpoints.config.js

module.exports = {
    preset: 'jest-puppeteer',
    testRegex: './breakpoints/',
}

And test file:

beforeAll(async () => {
    //  Getting TS2339: Property 'browser' does not exist on type 'Global
    page = await global.browser.newPage();
    script = `getComputedStyle(document.querySelector('img[alt="Google"]', null)).display`;
});

afterAll(async () => {
    await page.close();
});

describe('Breakpoint test', () => {
    it('should not display right nav at mobile breakpoint', async () => {
        page.setViewport({ width: 400, height: 600 });
        await page.goto('https://www.google.com/');
        const result = await page.evaluate(script);
        expect(result).not.toBeNull()
    }, 10000);
});

And it works. but I am getting this TS2339 tslint error. Could someone, please, help me to understand how to fix it without disabling TS-lint on this line.

Thank you!

it’s not an elegant solution, but you can add this line to solve this problem.

declare var global: any
