'Managing memory using TestNG framework while running selenium webdriver testings
I encounter memory issues where the automation suite which I am running is stuck at some point in a way that I cannot explain or understand, I am using TestNG framework to run my automation test suite the test is using 10 threads (configured in testng.xml file with selenium 3) and the test itself is running of jenkins (I am using docker to run the project), this is my testng.xml setup:
<?xml version="1.0" encoding="UTF-8" ?>

</suite>
and I am using docker compose file to run the automation suite on top of it and this is the docker compose file:
version: '3'
services:
cywar-test-automation:
image: markhobson/maven-chrome:jdk-11
stop_signal: SIGKILL
stdin_open: true
tty: true
privileged: true
user: root
working_dir: /opt/neo
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- ./:/opt/neo
- /dev/shm:/dev/shm
command: mvn clean test -Pregression
environment:
- MAVEN_OPTS=-Xms24g -Xmx24g
When I am running the automation suite I see that not all chrome processes are being closed after the test is over although I am using 'driver.quit'
this is how my webdriver initialization looks like:
public class BaseUiTest extends BaseApiTest {
private final Browser BROWSER = Browser.valueOf(EnvConf.getProperty("ui.browser.type"));
protected String ADMIN_USERNAME;
protected final String ADMIN_PASSWORD = EnvConf.getProperty("hackeruso.admin.user.password");
protected DriverFactory driver;
protected LoginPage loginPage;
protected CmsPage cmsPage;
protected UpperManagementToolBar upperManagementToolBar;
protected WebSiteCommonPage webSiteCommonPage;
@BeforeClass(alwaysRun = true)
@Parameters({"username"})
public final void BaseUiSetup(ITestContext context, @Optional String username){
if(username!=null) {
this.ADMIN_USERNAME = username; //For running tests using maven command with testng xml file
}else{
this.ADMIN_USERNAME = EnvConf.getProperty("hackeruso.admin.user.email"); //For running tests locally from IDE
}
open();
}
protected void open() {
driver = DriverFactory.open(BROWSER, TEST_DOWNLOAD_FOLDER);
loginPage = new LoginPage(driver);
cmsPage = new CmsPage(driver);
webSiteCommonPage = new WebSiteCommonPage(driver);
upperManagementToolBar = new UpperManagementToolBar(driver);
}
protected void navigateTo(String url) {
driver.get(url);
Log.i("Successfully navigated to =[%s]", url);
}
@AfterClass(alwaysRun = true)
public final void baseTeardown() {
Date testEndTime = new Date();
if (driver != null) {
printBrowserLog();
driver.quit();
}
Log.i("testEndTime=[%s]", testEndTime);
}
public DriverFactory getDriver() {
return driver;
}
}
