Java Randoop junit生成器为参数值指定空值

java junit

Java Randoop junit生成器为参数值指定空值,java,junit,randoop,Java,Junit,Randoop,我使用Randoop生成Junit，当参数不是前置类型时，它总是传递空值。例如，我有一个类ClassA，它的参数是非前置类型的方法，例如当methodString（String str，Entity Entity）测试生成的Junits具有传递的实体值的空值，并且它不创建可以传递的有效对象 编辑：我正在使用eclipse运行测试，因此我添加了在类路径中运行Randoop所需的JAR，下面是我传递的参数 gentests--testclass=test.ClassA--time limit=60

我使用Randoop生成Junit，当参数不是前置类型时，它总是传递空值。例如，我有一个类ClassA，它的参数是非前置类型的方法，例如当methodString（String str，Entity Entity）测试生成的Junits具有传递的实体值的空值，并且它不创建可以传递的有效对象

编辑：我正在使用eclipse运行测试，因此我添加了在类路径中运行Randoop所需的JAR，下面是我传递的参数

gentests--testclass=test.ClassA--time limit=60

注意：我还不能添加图像。因此，我无法共享eclipse运行命令窗口

如何配置Randoop为Junit测试传递非空值

    public void method(String str, Calendar date) {

        if(entity.getName().equals("Sting")) {

            System.out.println("email");

实体类

问题在于Randoop无法为抽象类生成测试用例，在本例中为java.util.Calendar

您可以在命令行或类列表文件中提供扩展抽象类的类的名称。例如，您可以使用--classlist=myclasses而不是--testclass=test.ClassA执行Randoop；在myclasses文件（名称中没有任何扩展名）中，放入：

我这样做，Randoop生成一些测试，如：
