用Java中的TestNG读取JSON中的测试数据

import org.testng.annotations.Test;
import org.testng.annotations.DataProvider;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
import java.io.FileReader;
import java.io.IOException;

@DataProvider(name = "testdata")
public Object[][] testData() throws IOException, ParseException {
    // 读取JSON文件
    FileReader reader = new FileReader("testdata.json");
    JSONParser jsonParser = new JSONParser();
    JSONObject jsonObject = (JSONObject) jsonParser.parse(reader);

    // 获取测试数据
    JSONObject testData = (JSONObject) jsonObject.get("testdata");
    int rowCount = testData.size();
    Object[][] data = new Object[rowCount][2];

    // 将测试数据存储到二维数组中
    int index = 0;
    for (Object key : testData.keySet()) {
        String input = (String) key;
        String expectedOutput = (String) testData.get(key);
        data[index][0] = input;
        data[index][1] = expectedOutput;
        index++;
    }

    return data;
}

@Test(dataProvider = "testdata")
public void testMethod(String input, String expectedOutput) {
    // 执行测试逻辑
    // ...
    // 断言实际输出与期望输出是否一致
    // ...
}

{
  "testdata": {
    "input1": "expectedOutput1",
    "input2": "expectedOutput2",
    "input3": "expectedOutput3",
    ...
  }
}
