java - 运行与安全管理器相关的 EvoSuite 测试时出现异常

问题描述

我正在尝试使用本教程运行 EvoSuite 测试。

我能够生成测试类并使用 java 8 编译它们。但是，当尝试使用以下命令运行它时，会引发异常。

java  -cp ".\log4j.jar;.\ojdbc6.jar;.\commons-codec-1.3.jar;.\slf4j-log4j12-1.7.16.jar;.\slf4j-api-1.7.16.jar;D:\proj\target\classes;.\evosuite-tests;.\evosuite-standalone-runtime-1.0.6.jar;.\junit-4.12.jar;.\hamcrest-core-1.3.jar;"   org.junit.runner.JUnitCore  com.u.g.KeyClient_ESTest

抛出异常：

    FAILURES!!!
    Tests run: 2,  Failures: 1

有人可以帮助/指导我解决这个问题吗？提前致谢。

附加信息：

测试类是一个单例，它使用 JDBC API 连接到数据库以检索某些值。

标签： javaevosuitejava-security-manager

解决方案

这是对我有用的解决方案。解决方案是使用以下 cmd 选项生成测试类

-Dsandbox_mode=OFF

生成测试类的完整命令是

C:\java8\jdk1.8.0_102\bin\java  -jar evosuite-master-1.0.6.jar -Dsandbox_mode=OFF -class com.u.g.KeyClient -projectCP ".\log4j.jar;.\ojdbc6.jar;.\commons-codec-1.3.jar;.\target\classes;"

对应的 KeyClient_ESTest_scaffolding 类会有 RuntimeSetting 关闭沙箱

@BeforeClass 
public static void initEvoSuiteFramework() { 
org.evosuite.runtime.RuntimeSettings.className = "com.ultimatix.gdpr.KeyClient"; 
org.evosuite.runtime.GuiSupport.initialize(); 
org.evosuite.runtime.RuntimeSettings.maxNumberOfThreads = 100; 
org.evosuite.runtime.RuntimeSettings.maxNumberOfIterationsPerLoop = 10000; 
org.evosuite.runtime.RuntimeSettings.mockSystemIn = true; 
org.evosuite.runtime.RuntimeSettings.sandboxMode = org.evosuite.runtime.sandbox.Sandbox.SandboxMode.OFF; 
org.evosuite.runtime.sandbox.Sandbox.initializeSecurityManagerForSUT(); 
org.evosuite.runtime.classhandling.JDKClassResetter.init();
setSystemProperties();
initializeClasses();
org.evosuite.runtime.Runtime.getInstance().resetRuntime();

}

希望它可以帮助面临类似问题的人。
