我正在用IntelliJ编写Selenium Junit测试。如果我直接从测试中触发，则测试运行正常。但是，如果我使用JunitCore触发了来自TestRunnerSuite的测试，则会遇到以下奇怪的错误，在谷歌搜索后我找不到解决方案。关于DriverService $ builder的类似问题，但不是我的错误类型。

我正在使用Selenium 3.5.3和chrome76。 --->已更新为Selenium 3.141.59，范围为main。

我的项目文件夹结构是
.src
...main
.....java
.......projectname
.........constantsFolder
.........utilFolder
...........util1.java
...........util2.java
.........Test1.java
.........TestRunnerSuite.java
.........WebDrivers.java
如果我从Test1.java开始测试，尽管有警告，测试仍会正常运行
[main] INFO projectname.util.util1 - Set up chrome driver.
Starting ChromeDriver 75.0.3770.90 (a6dcaf7e3ec6f70a194cc25e8149475c6590e025-refs/branch-heads/3770@{#1003}) on port 28755
Only local connections are allowed.
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

但是，在添加如下所示的testSuiteRunner之后。
@RunWith(Suite.class)
@Suite.SuiteClasses({ Test1.class })
public class TestSuiteRunner {
public static void main(String[] args) {
Result result = JUnitCore.runClasses(Test1.class);
// print erros, exit etc omitted
}
}
现在，我得到了奇怪的错误，无法启动chromedriver。 我拥有的Webdriver是Singleton
public class WebDrivers {
private static WebDriver driver = null;
public static WebDriver getInstance(){
if (driver == null) {
driver = new ChromeDriver();
}
return driver;
}
}
这是我第一次尝试从地面进行一切设置。我不确定是pom依赖问题，单例webdriver问题还是其他原因。谁能对此发表看法并提供一些线索？非常感激。

此错误消息...
java.lang.AbstractMethodError: org.openqa.selenium.remote.service.DriverService$Builder.createArgs()Lcom/google/common/collect/ImmutableList;
...表示您使用的二进制版本之间特别存在 guava 依赖。 >
您正在使用以下内容：
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-chrome-driver</artifactId>
<version>3.5.3</version>
<scope>test</scope>
</dependency>
您的 Selenium Client 版本是 3.5.3 ，比版本 2 年还早。
因此 Selenium Client v3.5.3 和 Chrome浏览器v76.0
之间显然不匹配但是根据以下讨论：
由于不兼容的 Guava 依赖性，这些问题浮出水面。
selenium-java-3.141.59中使用的当前 guava 版本是 guava-25.0-jre
确保：
@Test。driver.quit()方法内调用tearDown(){}，以优雅地关闭和销毁 WebDriver 和 Web Client 实例。大概是您对错误的主要疑问：
java.lang.AbstractMethodError: org.openqa.selenium.remote.service.DriverService$Builder.createArgs()Lcom/google/common/collect/ImmutableList;
已已解决。恭喜你
现在，根据您看到的错误更新您的问题：
java.lang.NoClassDefFoundError: org/apache/http/auth/Credentials
有两个方面。
http/auth： http / auth 的痕迹表明 http client 仍在使用中，正如CHANGELOG反映的那样：
HttpClient实现细节不属于HttpCommandExecutor。OkHttp 而不是 Apache HttpClient 。Apache HttpClient 从selenium-server-standalone中被彻底删除，
减少了硒服务器分发软件包的大小。apache-backed httpclient也已删除。答案 1 :(得分：2)
从POM中删除范围。 测试 或主要 不需要运行测试
答案 2 :(得分：0)
在最新的 testng 7.3 中使用了这个 gauva jar。解决了这个错误也不要单独配置任何 testNG。如果我们在 pom.xml
