How can I use a Webdriver Testcontainer in Bitbucket Pipelines? - webdriver

Question

When trying to use a Webdriver Testcontainer in Bitbucket Pipelines, I get the following error messages:
[main] WARN 🐳 [selenium/standalone-chrome:4.1.1] - Unable to mount a file from test host into a running container. This may be a misconfiguration or limitation of your Docker environment. Some features might not work.
[main] ERROR 🐳 [selenium/standalone-chrome:4.1.1] - Could not start container
com.github.dockerjava.api.exception.DockerException: Status 403: {"message":"authorization denied by plugin pipelines: -v only supports $BITBUCKET_CLONE_DIR and its subdirectories"}
My testcontainers version is 1.17.6
Here is the code I'm using while trying to troubleshoot:
package com.byzpass.demo;
import org.junit.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testcontainers.containers.BrowserWebDriverContainer;
public class SeleniumTest {
public ChromeOptions chromeOptions = new ChromeOptions().addArguments("--no-sandbox").addArguments("--headless").addArguments("--disable-dev-shm-usage");
#Rule
public BrowserWebDriverContainer<?> driverContainer = new BrowserWebDriverContainer<>().withCapabilities(chromeOptions);
#Test
public void openWikipedia() {
WebDriver driver = new RemoteWebDriver(driverContainer.getSeleniumAddress(), chromeOptions);
driver.navigate().to("https://www.wikipedia.org/");
String subtitleText = driver.findElement(By.cssSelector("#www-wikipedia-org h1 strong")).getText();
assert subtitleText.equals("The Free Encyclopedia");
driver.quit();
System.out.println("Finished opening wikipedia. 📖 🤓 🔍 👍 ✨");
}
}
Here is my bitbucket-pipelines.yml:
pipelines:
default:
- step:
image: amazoncorretto:11
services:
- docker
script:
- export TESTCONTAINERS_RYUK_DISABLED=true
- cd selenium-test ; bash ./mvnw --no-transfer-progress test
definitions:
services:
docker:
memory: 2048
By setting a breakpoint in my test method and using docker inspect -f '{{ .Mounts }}' I was able to discover that the container for the selenium/standalone-chrome:4.1.1 image has [{bind /dev/shm /dev/shm rw true rprivate}]
I thought that using the --disable-dev-shm-usage argument in my chrome options would prevent that, but it didn't. I don't know whether that's what's causing my issue in Bitbucket Pipelines though.

I found that it worked after setting shm size to zero. Here's the code that worked:
package com.byzpass.demo;
import org.junit.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testcontainers.containers.BrowserWebDriverContainer;
import java.util.ArrayList;
public class SeleniumTest {
#Test
public void openWikipedia() {
ChromeOptions chromeOptions = new ChromeOptions().addArguments("--no-sandbox").addArguments("--headless").addArguments("--disable-dev-shm-usage");
BrowserWebDriverContainer driverContainer = new BrowserWebDriverContainer<>().withRecordingMode(BrowserWebDriverContainer.VncRecordingMode.SKIP, null);
driverContainer.setShmSize(0L);
driverContainer.start();
WebDriver driver = new RemoteWebDriver(driverContainer.getSeleniumAddress(), chromeOptions);
driver.navigate().to("https://www.wikipedia.org/");
String subtitleText = driver.findElement(By.cssSelector("#www-wikipedia-org h1 strong")).getText();
assert subtitleText.equals("The Free Encyclopedia");
driver.quit();
driverContainer.stop();
System.out.println("Finished opening wikipedia. 📖 🤓 🔍 👍 ✨");
}
}
