使用 maven 和 WebDriverManager 在 Jenkins 上找不到 Chrome 二进制错误

Question

I'm trying to run my test (Selenium+junit+cucumber+Maven) on Jenkins. In my definition class I'm not pointing to Chrome binary but rather use WebDriverManager:

@Given("^I navigate to page$")

public void i_navigate_to_webpage() throws Throwable {

    String url = Helper.getPropValue("landing", "navigation");

    WebDriverManager.chromedriver().setup();
    driver = new ChromeDriver();
    wait = new WebDriverWait(driver,20);

    driver.manage().window().maximize();
    driver.get(url);

}

It works fine on my machine (Win), but when I'm trying to execute this on Jenkins (Ubuntu box), I get error:

org.openqa.selenium.WebDriverException: unknown error: cannot find Chrome binary (Driver info: chromedriver=2.35.528139 (47ead77cb35ad2a9a83248b292151462a66cd881),platform=Linux 4.4.0-1047-aws x86_64) (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 687 milliseconds Build info: version: '2.48.2', revision: '41bccdd10cf2c0560f637404c2d96164b67d9d67', time: '2015-10-09 13:08:06' System info: host: 'ip-172-31-12-150', ip: '172.31.12.150', os.name: 'Linux', os.arch: 'amd64', os.version: '4.4.0-1047-aws', java.version: '1.8.0_151' Driver info: org.openqa.selenium.chrome.ChromeDriver at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.openqa.selenium.remote.

I was under impression that WebDriverManager should have covered that how it does on my Windows machine. Isn't it so?

Answer 1

Your chrome on Ubuntu is not installed into default location:

More detail

you can add the chrome binary to PATH environent variable or reinstall it to default location.

Make sure chromedriver compatible with chrome browser, check this link to get compatible mapping

Chromedriver 2.35 Supports Chrome v62-64

When run script from Linux terminal tunnel, like run by Jenkins. In general, Linux terminal tunnel not have display screen, but run script with headful model require a physical or virtual display.

Option 1: run with headless model when not setup virtual display by xWindow/xvbf

ChromeOptions options = new ChromeOptions();
options.addArguments("headless");
// Must maximize Chrome by `start-maximized`
options.addArguments("start-maximized");

//Dont maximize Chrome by below line, because has no display
driver.manage().window().maximize()

Option 2: run with headful model, but need setup virtual display for the user which Jenkins used to connect to your Ubuntu box or you setup for all users if you can't know which user.

Please read document about Xvbf or other xWindow to setup virtual display.

Answer 2

您可以在 Jenkins 的构建设置中设置 chrome 路径作为目标：

-Dselenide.browserBinary="chrome/path_to_exe"
