如何在 Mac OS 和 Eclipse 中使用 FireFox 运行简单的 Selenium 自动化测试

Question

Im having an issue with running automation test with Selenium in Firefox adding the Geckodriver to my Java project that I have downloaded. Whatever jar files I'm adding I'm getting the same error message in the Eclipse console.

I have downloaded these following files to my project in Eclipse from

https://www.seleniumhq.org/download/ :

Java file

Geckodriver

So I assume that these above files should be the latest ones?

However when Im running the small Java program below:

    public static void main(String[] args) {

    System.setProperty("webdriver.gecko.driver", "/Users/myName/Desktop/geckodriver");
    System.setProperty("webdriver.firefox.bin", "/Applications/Firefox.app/Contents/MacOS/firefox-bin");

    WebDriver driver = new FirefoxDriver();

    driver.get("http://www.google.com");


}

...Im getting the following error:

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)V at org.openqa.selenium.remote.service.DriverService.checkExecutable(DriverService.java:146) at org.openqa.selenium.firefox.GeckoDriverService.access$000(GeckoDriverService.java:44) at org.openqa.selenium.firefox.GeckoDriverService$Builder.usingFirefoxBinary(GeckoDriverService.java:160) at org.openqa.selenium.firefox.FirefoxDriver.toExecutor(FirefoxDriver.java:187) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.Z93F725A07 423FE1C889F448B33D21F46Z:147) at org.openqa.selenium.firefox.FirefoxDriver.(FirefoxDriver.java:125) at test.SeleniumTest.main(SeleniumTest.java:14)

These are the jars in my Build path: Build path in Eclipse

My Eclipse version: Oxygen.3a Release (4.7.3a)
My Firefox Version: Firefox Quantum (69.0.34, 64-bit)
My Mac OS Version: OS X El Capitan (10.11.6)

Im still confused why because I just followed a lot of tutorials out there explaining it on how to achieve the automation test.

Did I just missed to add something to my project?

All help and advice would be highly appreciated

Read this trouble ticket . You have an outdated version of guava.

Update guava here .

You should be able to add the guava JAR file to your Eclipse project by right clicking on the project name and selecting Build Path > Libraries > Add External JAR.
