Chromedriver memory leak

[R J]

Hello,

my chromedriver blocks 2-4 megabytes for each opening of the driver / url, which leads to a memory leak during massive unit tests.

Following command frees the issue

echo 3 | sudo tee /proc/sys/vm/drop_caches  

 

Env:

Driver.quit() is executed...

Chromedriver 91

Used Windows WSL

Are there any threads or fixes for this?

TestCode following:

const chrome = require('selenium-webdriver/chrome.js')

const sd = require('selenium-webdriver')

const Builder = sd.Builder

const Capabilities = sd.Capabilities

async function getDriver() {

    const service = new chrome.ServiceBuilder("./selenium/chromedriver");

    const options = new chrome.Options();

    const chromeCapabilities = Capabilities.chrome()

    const driver = new Builder()

        .withCapabilities(chromeCapabilities)

        .setChromeService(service)

        .setChromeOptions(options)

        .build();

    return driver;

}

async function Main(){

    const url = "http://127.0.0.1"

    for (let i = 0; i < 1000; i++) {

        const driver =  await getDriver()

        await driver.get(url);

        driver.quit()

    }

}

Main()

Hi,

Not really, but the memory handling of Linux do this automatically for me I got the same runtime if I had unlimited memory as well I used a test system with only 100mb memory.

But to use and work on my dev environment further you can regular clear your cache manually or coded  in Linux wsl.windows Subsystem via 

echo 3 | sudo tee /proc/sys/vm/drop_caches
