Hi Kaushik it solved by Updating Dependencies in Package.json like "devDependencies": {
"jest": "^27.5.1",
"jest-playwright-preset": "^1.7.0",
"playwright": "^1.19.2",
"ts-jest": "^27.1.3",
"typescript": "^4.6.2"
}, This will help others also if they face same issue.. Thanks Kaushik for this series.

Nice video!!

Question: Can we alter the jest-playwright.config.js file at runtime? Specifically altering the browsers under test. This would be required/useful when running in CI. Deciding to run on one two or three browsers

Thanks again

Hi Koushik, very nice videos. I have a jest-playwright-config.js file as below. I'm specifying the recordVideo section in the file but its not recording any videos. I have double checked the path and it is correct, but don't know why its not working, any inputs?

module.exports = {
browsers: ["chromium"],
contextOptions: {
viewport: null,
acceptDownloads: true,
recordVideo: {dir: "./videos"
}
},
exitOnPageError: false,
launchOptions: {
args:["--start-maximized"],
headless: false,
slowMo: 100
}
}
