java - 如何正确使用Java集成库中的越狱进行junit测试？

我正在使用Java的manifold扩展库进行junit测试，即使完全按照其docs进行操作，我也无法弄清楚自己在做什么。

// My Class
package practice_junit;

public class SomeClass
{
    public SomeClass()
    {

    }

    private String get_string()
    {
        return "ABCDE";
    }
}

// My Unit Test Class -- first way
package practice_junit;

import manifold.ext.api.Jailbreak;
import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class SomeClassTest
{
    public SomeClassTest()
    {

    }

    @Test
    public void assert_equals_true_test()
    {
        @Jailbreak SomeClass sc = new SomeClass();
        assertEquals("Error equals","ABCDE",sc.get_string());
    }
}

// My Unit Test Class -- second way
package practice_junit;

import manifold.ext.api.Jailbreak;
import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class SomeClassTest
{
    public SomeClassTest()
    {

    }

    @Test
    public void assert_equals_true_test()
    {
        SomeClass sc = new SomeClass();
        assertEquals("Error equals","ABCDE",sc.jailbreak().get_string());
    }
}

在两种情况下，我都会得到相同的错误日志:

PS C:\Users\> gradle build

> Task :compileTestJava FAILED
C:\Users\SomeClassTest.java:19: error: get_string() has private access in SomeClass
                assertEquals("Error equals","ABCDE",sc.get_string());
                                                      ^

我正在使用gradle和歧管扩展依赖项作为https://mvnrepository.com/artifact/systems.manifold/manifold-ext/2019.1.12中的compile group: 'systems.manifold', name: 'manifold-ext', version: '2019.1.12'

最佳答案

您正在使用什么版本的Java？如果是Java 9或更高版本，是否正在使用JPMS(模块)？如果您发布Gradle脚本，我会帮助您正确设置它。更好的是post an issue on the manifold github，其中包含指向您的项目的链接。可能未明确设置--module-path，这是使用Java 9+的Gradle脚本的一个非常普遍的问题。以下是相关的位:

dependencies {
    compile group: 'systems.manifold', name: 'manifold-ext', version: '2019.1.12'
    testCompile group: 'junit', name: 'junit', version: '4.12'

    // Add manifold to -processorpath for javac (for Java 9+)
    annotationProcessor group: 'systems.manifold', name: 'manifold-ext', version: '2019.1.12'
}

compileJava {
    doFirst() {
        // If you DO NOT define a module-info.java file:
        options.compilerArgs += ['-Xplugin:Manifold']

        // if you DO define a module-info.java file:
        //options.compilerArgs += ['-Xplugin:Manifold', '--module-path', classpath.asPath]
        //classpath = files()
    }
}

Manifold项目倾向于在任何地方使用Maven。 Gradle设置文档不够完善。
