JAVA 中的 DDT Json 与 Selenium

Question

我正在尝试使用 Json 来参数化程序。

数据以简单文本格式存储在data.JSON中

我已经添加了所有依赖项。

当我尝试运行时，下面的代码给了我失败。请让我知道为什么这段代码可能是错误的。

JSONDataClass

public class JsonDataClass {

    @Test
         public List<HashMap<String, String>> getJsonDataToMap() throws IOException
        {
        String FileDir = System.getProperty("user.dir")+"//src//DDT//data.json";
        System.out.println(FileDir);
        
        String jsonContent = FileUtils.readFileToString(new File(System.getProperty("user.dir")+"//src//DDT//data.json"),StandardCharsets.UTF_8);
        System.out.println(jsonContent);
        //List<HashMap<String, String>> data = mapper.readValue(jsonContent, new TypeReference<List<HashMap<String, String>>>());
         List<HashMap<String, String>> dataHashMap = new Gson()
                    .fromJson(jsonContent, 
                        new TypeToken<List<HashMap<String, 
                            String>>>() {}.getType());
                return dataHashMap; 
        }

        
   
    
    @DataProvider
    public Object[][] getData() throws IOException{
        List<HashMap<String, String>> pdata =getJsonDataToMap();
    
        return new Object[][]{{pdata.get(0)},{pdata.get(1)}};
    }
    
    
    
    
    
    @Test(dataProvider="getData")

    public void fetchingdata(HashMap<String, String> input) 
    {
        System.out.println(input.get("email"));
        System.out.println(input.get("username"));
        System.out.println(input.get("password"));
    }
    
}

数据.JSON

[
    {
        "email":"[email protected]",
        "username":"[email protected]",
        "password":"pass123"
    }

    {
        "email":"[email protected]",
        "username":"[email protected]",
        "password":"pass2222"
    }
]
