我正在使用 request.batch 运行 K6 测试，其中每个测试的请求数都可以改变。

req = [req0, req1, req2, ...];
let res = http.batch(req);

然后，我尝试为每个请求运行“检查”，并使用 while 循环来执行此操作。

while (i < req.length) {
    check(
      res[i],
      {" ${i} - status 200": (r) => r.status === 200 }
    );
    i++;
}

但是 K6 将所有“检查”测试结果累积在一个测试中，因为测试消息不会解析我通过的变量。输出在测试结束时打印此消息：

done [===============] 10s / 10s
✓  ${i} - status 200

我尝试使用不同的方式添加参数，但没有用：

{ i + " - status 200": (r) => r.status === 200 }
{' ${i} - status 200': (r) => r.status === 200 }
{` ${i} - status 200`: (r) => r.status === 200 }
{" %d - status 200", i : (r) => r.status === 200 }

我想知道是否有任何原因要在此处传递自定义消息。

不确定您是否已经有了答案，但对于其他人，您可以使用括号表示法来分配属性名称。请参阅下面的示例和以下链接：如何从 JavaScript 中的变量值创建对象属性？

import http from "k6/http";
import { check } from "k6";

export default function() {
    let response = http.get("https://test.loadimpact.com");
    let test = "x";
    check(response, {
        [test + " - status 200"]: (r) => r.status === 200
    });
};

这将产生以下输出：

done [==========================================================] 1 / 1i

✓ x - status 200
