Research direction

Start with the Playwright helper configuration in conf.js, especially windowSize, chromium.args, and viewport, and reproduce the behavior on Windows 11 with CodeceptJS 3.6.7 and Node.js 20.12.2. Done means the configured Playwright browser reliably opens maximized without requiring a separately launched browser or manual page replacement.

Written by the indexing model from the issue text.

Description

I want to maximize the window where my app fit to the entire screen perfectly

By using the option (windowSize = "maximize") in conf.js file does not work.

  • CodeceptJS version: 3.6.7
  • NodeJS Version: 20.12.2
  • Operating System: Windows 11
  • playwright
  • Configuration file:
    const { default: test } = require("playwright/test");

exports.config = {
output: './output',
tests: './other_tests/**.test.js',
helpers: {
Playwright: {
browser: 'chromium',
url: 'localhost:3000',
show: true,
getPageTimeout: 180000,
waitForTimeout: 180000,
waitForNavigation: "networkidle0",
restart: "session",
keepBrowserState: true,
keepCookies: true,
windowSize: "maximize",
chromium: {
args: ['--start-maximized'],
viewport: null
}
},
Generics: {
require: "./helpers/generics.js"
},
ExpectHelper: {}
},
include: {
I: './steps_file.js'
},
timeout: 560,
gherkin: {
features: './features/*.feature',
steps: ['./step_definitions/steps.js'],
},
plugins: {
screenshotOnFail: {
enabled: true
},
tryTo: {
enabled: true
},
allure: {
enabled: true,
require: '@codeceptjs/allure-legacy',
}
},
name: 'test_Automation'
}

I even tried to extend playwright method where I able to maximize the window but not sure how to reuse the new context as I need to close the one created by codeceptjs fixture.

const { chromium } = require('playwright');

Feature('Maximize Browser Window');

Scenario('Maximize window using Playwright', async ({ I }) => {
I.amOnPage('http://localhost'); // Replace with your URL

I.usePlaywrightTo('maximize browser window', async ({ page }) => {
// Close the existing browser context
const browser = page.context().browser();
await browser.close();

// Launch a new browser instance with the --start-maximized argument
const newBrowser = await chromium.launch({
  headless: false,
  args: ["--start-maximized"],
});

// Create a new browser context with a maximized viewport
const context = await newBrowser.newContext({ viewport: null });
const newPage = await context.newPage();

// Navigate to the specified URL
await newPage.goto('http://localhost'); // Replace with your URL

// Set the new page for further CodeceptJS steps
I._setPage(newPage);

});

// Continue with your test steps using the new page
I.see('Welcome');
});
