无法将json测试数据文件读入我的stepDef

Question

无法读取json测试数据文件到我的stepDef。当我试图在maven中执行此操作时，我会收到下面的错误消息。

我的场景大纲：JSON关键字示例，假设我在github登录页面#，输入“”和“”，输入用户名和密码

Examples: {'datafile':'./src/main/resources/data/testData.json'}

我的测试数据。json

[
  { "username" : "jsonuser1" , "password":"jsonpass1" , "isvalid":"false" }
]

分步定义

@And("^I enter usernames and passwords$")
public void iEnterUsernamesAndPasswords(Map<Object, Object> data) {
    System.out.println("*************************"+ data.get("username") + data.get("password"));
    
}

错误msg：

对于任何需要参数的步骤，在定义步骤时需要指定参数占位符，并且需要提供调用时间的值。在您的情况下，请尝试更新步骤定义，如下所示：

@And("^I enter usernames and passwords \"([^\"]*)\"$")
public void iEnterUsernamesAndPasswords(Map<Object, Object> data) {
System.out.println("*************************"+ data.get("username") + data.get("password"));
}

在步骤调用时传递数据，
