无法将 json 测试数据文件读入我的 stepDef。当我尝试在 Maven 中执行此操作时，我收到以下错误消息。

我的场景场景大纲：JSON 关键字示例给定我在 github 登录页面 #And I enter "" and "" And I enter users and passwords

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

我的 testData.json

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

步骤定义

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

错误信息：

对于任何需要参数的步骤，您需要在定义步骤时指定参数占位符，并且需要提供调用时间的值。在您的情况下，尝试如下更新步骤定义：

@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，

My Scenario

    Given I am on github login page
    And I enter usernames and passwords "${args[0]}"

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