Junit在surefire中运行失败

Question

我面临着另一个问题。我的项目中有5个测试类（junit），它们都能够进行参数化测试。我可以用eclipse单独测试这些类，那时它工作得很好。当我通过maven（sure fire）运行它们时，它们失败了。错误消息看起来像org。朱尼特。跑步者。参数化。ParametersMethodReturnedErrorType（参数化。java:340）。请帮忙。

代码片段：

@Parameters
    public static List<Browser> getBrowserDetails() {
        ConfigReader reader = new ConfigReader();
        return reader.getParameter(ProjectTest.class.getCanonicalName());
    }

堆栈跟踪：

Answer 1

ProjectTest.getBrowserDetails() must return an Iterable of arrays

你有你的理由。方法返回的列表不包含数组，但包含浏览器对象。

在JUnit 4.11之前，该方法的正确签名将是：

public static List<Browser[]> getBrowserDetails()
