Taurus 在 Windows 上执行 apachebenchmark 失败答案

【问题标题】：Taurus failed execute apachebenchmark on windowsTaurus 在 Windows 上执行 apachebenchmark 失败
【发布时间】：2018-12-08 09:21:56
【问题描述】：

我正在使用 Winsows 7 并下载最新的 Taraus 安装，从 ApacheServer 安装下载更新的 ApacheBenchmark。

我正在尝试使用 Taraus 的 Simplest working example 执行 ApacheBenchmark

调用bzt config.yaml，但使用Invalid number of requests 失败

execution:
- executor: ab
  scenario: simple

scenarios:
  simple:
    requests:
    - http://blazedemo.com/

但是失败了

16:16:07 ERROR: ab STDERR:

Invalid number of requests

当我尝试第二个示例时 hold-for 使用示例 taurus 打开并崩溃

是否存在 taraus Windows 问题或已知限制？因为我缺少配置/执行参数？

注意，我在安装新版本之前卸载了旧版本，并且 config.yaml 是有效的 yaml 文件

ApacheBenchmark 独立运行，例如在执行时

ab http://blazedemo.com/

如果你坐在一个有缺陷的版本上，你可以像这样简单地获得 Taurus v1.13.1：

pip install bzt==1.13.1

万一有Taurus Support Forum 可以联系到 Taurus 开发人员和维护人员，在那里获得更专业答案的机会要高得多。

【讨论】：

如果 ab.exe 是 windows 路径的一部分，-o 是否必要？

【解决方案2】：

Taurus 论坛回应称这是一个需要修复的错误并提出了解决方法：

现在您可以使用显式并发和迭代作为解决方法：
execution:
 - executor: ab
   iterations: 1
   concurrency: 1
