我正在使用RequestsScala模块发出HTTP请求，如下所示：

object AEMUtility {
    ....
    def getJWTToken() {
    ....
    val response = requests.post(
      s"$imsExp/ims/exchange/jwt/",
      headers = Map(
        "Content-Type" -> "application/x-www-form-urlencoded"
      ),
      params = Map(
        "client_id" -> clientId,
        "client_secret" -> clientSecret,
        "jwt_token" -> token
      )
    )
    }
}

我想通过以下方式模拟POST请求函数来编写单元测试：检查Mock函数中传递的参数并返回伪响应。
有没有办法在Scala中模拟安装的依赖关系？
我试过：

"authorize" should "return JWT token if request is valid" in {
    val postMock = mock[requests.post]

  }

但这给了我错误：Cannot resolve symbol post
