For some reason when I run my tests at work the browser is maximized, but when I run them at home it only opens a browser window of about 50% width. This causes some discrepancies with scrolling down, etc., so I'd ideally like to have it open a browser window of the same size on every machine the tests are run on. What's the best way to do this?
(I've found some answers for other languages, but I haven't been able to adapt them to JavaScript)
Adding
browser.executeScript('window.moveTo(0,0);' +
'window.resizeTo(screen.width, screen.height);');
does nothing (apparently window.moveTo
and window.resizeTo
are not supported by Google Chrome).
You can also use your config. js to set window size: // config. js specs: [ ... ], capabilities: { browserName: 'chrome', chromeOptions: { args: ['--window-size=800,600'] // THIS! } } // ....
Protractor allows setting the custom browser window size. Custom width and height can be mentioned in the Set Size function, the browser window will be resized to the mentioned width and height. Purpose: The function setSize() in the Window class is used to resize the browser window.
You can also get the WINDOW width and height, avoiding browser toolbars and other stuff. It is the real usable area in browser's window. To do this, use: window. innerWidth and window.
You can set the default browser size by running:
var width = 800;
var height = 600;
browser.driver.manage().window().setSize(width, height);
To maximize the browser window, run:
browser.driver.manage().window().maximize();
To set the position, run:
var x = 150;
var y = 100;
browser.driver.manage().window().setPosition(x, y);
If you get an error:
WebDriverError: unknown error: operation is unsupported with remote debugging
Operation not supported when using remote debugging Some WebDriver commands (e.g. resizing the browser window) require a Chrome extension to be loaded into the browser. ChromeDriver normally loads this "automation extension" every time it launches a new Chrome session.
However ChromeDriver can be instructed to connect to an existing Chrome session instead of launching a new one. This is done using 'debuggerAddress' in the Capabilities (aka ChromeOptions) object. Since the automation extension is only loaded at startup, there are some commands that ChromeDriver does not support when working with existing sessions through remote debugging.
If you see the error "operation not supported when using remote debugging", try rewriting the test so that it launches a new Chrome session. This can be done by removing 'debuggerAddress' from the Capabilities object.

You can also use your config.js
to set window size:
// config.js
specs: [
...
],
capabilities: {
browserName: 'chrome',
chromeOptions: {
args: ['--window-size=800,600'] // THIS!
}
}
// ....
If the preferred method:
browser.driver.manage().window().maximize();
doesn't work for you (for example running Protractor tests in Xvfb), then you can also maximize window this way (protractor.conf.js):
onPrepare: function() {
setTimeout(function() {
browser.driver.executeScript(function() {
return {
width: window.screen.availWidth,
height: window.screen.availHeight
};
}).then(function(result) {
browser.driver.manage().window().setSize(result.width, result.height);
});
});
},
TypeScript version:
import {Config, browser} from "protractor";
export let config: Config = {
...
onPrepare: () => {
setTimeout(() => {
browser.driver.executeScript<[number, number]>(() => {
return [
window.screen.availWidth,
window.screen.availHeight
];
}).then((result: [number, number]) => {
browser.driver.manage().window().setSize(result[0], result[1]);
});
});
}
};
I simply added the code below in my protractor.conf.js file and it did work fine.
onPrepare: function() {
var width = 1600;
var height = 1200;
browser.driver.manage().window().setSize(width, height);
},
What purpose does the setTimeout and executeScript serve in your answer? I struggle to find best practices in the protractor documentation...
To my mind, using directly maximize() is a bad idea and should not be the preferred method, since it would not set the same size on every machine where the tests are executed and could break responsive behaviours.
