所以我最近在尝试使用IDE运行现有测试套件时开始面对TestNGException。最近我的意思是更新intelliJ和依赖项以尝试处理最新版本。失败的代码和堆栈跟踪如下 -
代码使用
ITests.java -
public class ITests extends BaseTest {
private final Action action = new Action();
}
BaseTest （只是为了分享语法） -
public class BaseTest {
// where in this class does not use any instance of Http
}
Action.java -
public class Action {
private final Http http = Http.getInstance();
}
Http.java -
public class Http {
private static final Http INSTANCE = new Http(); //line 36
public static Http getInstance() {
return INSTANCE;
}
private Http() {
PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(); //line 43
connectionManager.setMaxTotal(100);
connectionManager.setDefaultMaxPerRoute(100);
RequestConfig defaultRequestConfig = RequestConfig.custom()
.setSocketTimeout(60000)
.setConnectTimeout(60000)
.setConnectionRequestTimeout(60000)
.build();
this.client = HttpClients.custom().setDefaultRequestConfig(defaultRequestConfig)
.setConnectionManager(connectionManager).build();
}
}
Maven依赖 -
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.2</version>
</dependency>

注意 - 我们的项目基于maven，所以当我使用maven exec:java执行测试时，执行顺利。
请询问所需的任何其他信息。

正如@hunter所要求的那样，调试以获取加载位置的Cpool的确切路径。评估 -
Class.forName("org.apache.http.impl.conn.CPool").getResource("CPool.class")
结果 -
文件：/Users/xyz/.m2/repository/org/apache/httpcomponents/httpclient/4.5.2/httpclient-4.5.2.jar /org/apache/http/impl/conn/CPool.class < / p>

答案 0 :(得分：3)
在IDEA， Maven项目标签中，点击显示依赖关系按钮（它将显示图表），然后在该图表中按Ctrl+ F并输入httpcore并检查版本。如果它显示的版本低于4.4，则可以分析依赖关系的解析方式。在此基础上，您可以调整pom来纠正依赖关系。由于它在命令行中使用mvn，因此这可能是该IDEA通过其maven插件解析maven依赖项的错误行为。
