基于Python在MacOS上安装robotframework-ride

Robotframework是一个框架，是一个可以用于关键字测试驱动的框架。而RIDE（robotframework-ride）就是可以使得写robot测试用例更加方便快捷的IDE图形操作工具。

安装

因为是基于python的，所以其可以运行在多个操作系统上。这里主要介绍一下RIDE在MacOS上的使用方式。

OS版本

MacOS版本：10.13.2

wxpython

由于RIDE是基于wxpython的应用，所以首先需要保证wxpython已经得到了安装。安装命令如下：

安装命令：brew install wxpython

defaulting this GNU Readline installation to keg-only.

版本确认

liumiaocn:~ liumiao$ brew info wxpython
wxpython: stable 3.0.2.0 (bottled)
Python bindings for wxWidgets

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/wxpython.rb
==> Dependencies
Required: python@2 ✔, wxmac ✔
liumiaocn:~ liumiao$

暂定对应1：wxpython安装之后，目前的版本还缺少一个软连接才能正常动作，根据日志可以看到此次安装的wxpython版本为wxpython-3.0.2.0_1, 按照如下操作创建软连接即可

创建链接

liumiaocn:bin liumiao$ pwd
/usr/local/bin
liumiaocn:bin liumiao$ ls wx
ls: wx: No such file or directory
liumiaocn:bin liumiao$ ln -s ../Cellar/wxpython/3.0.2.0_1/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx wx
liumiaocn:bin liumiao$

确认方式

liumiaocn:~ liumiao$ python -c "import wx; print wx.VERSION"
/usr/local/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/_core.py:16633: UserWarning: wxPython/wxWidgets release number mismatch
 warnings.warn("wxPython/wxWidgets release number mismatch")
(3, 0, 2, 0, '')
liumiaocn:~ liumiao$

虽然仍然提示warning信息，但是已经能够正常继续动作了。

安装robotframework-ride

使用pip安装robotframework-ride, 安装命令如下

安装命令：pip install robotframework-ride

启动确认

通过ride.py启动RIDE，当前版本出现了如下错误信息

liumiaocn:bin liumiao$ ride.py
Wrong wxPython version.
You need to install wxPython 2.8.12.1 with unicode support to run RIDE.
wxPython 2.8.12.1 can be downloaded from http://sourceforge.net/projects/wxpython/files/wxPython/2.8.12.1/
liumiaocn:bin liumiao$

原因确认：经过定位代码中错误出现的位置，确认到如下文件：

liumiaocn:local liumiao$ find . -name '*.py' |xargs grep 'You need to install wxPython'
./lib/python2.7/site-packages/robotide/__init__.py:You need to install wxPython 2.8.12.1 with unicode support to run RIDE.
liumiaocn:local liumiao$ view ./lib/python2.7/site-packages/robotide/__init__.py
liumiaocn:local liumiao$ grep supported_versions ./lib/python2.7/site-packages/robotide/__init__.py
supported_versions = ["2.8"]
    supported_versions.append("2.9")
  wxversion.select(supported_versions)
liumiaocn:local liumiao$

对应方法1：直接将支持的版本号修改为当前的版本

liumiaocn:~ liumiao$ diff /usr/local/lib/python2.7/site-packages/robotide/__init__.py /usr/local/lib/python2.7/site-packages/robotide/__init__.py.org
37,38c37
< #supported_versions = ["2.8"]
< supported_versions = ["3.0.2.0"]
---
> supported_versions = ["2.8"]
liumiaocn:~ liumiao$

对应方法2：添加supported_versions

liumiaocn:~ liumiao$ diff /usr/local/lib/python2.7/site-packages/robotide/__init__.py /usr/local/lib/python2.7/site-packages/robotide/__init__.py.org
44d43
<     supported_versions.append("3.0.2.0")
liumiaocn:~ liumiao$

实际上在如下行添加了对当前版本的支持

try:
   import wxversion
   from wxversion import VersionError
   if sys.platform == 'darwin':
     supported_versions.append("2.9")
     supported_versions.append("3.0.2.0")
   wxversion.select(supported_versions)
   import wx

安装robotframework

使用pip install robotramework进行robotframework的安装

liumiaocn:~ liumiao$ pip install robotframework

liumiaocn:~ liumiao$

启动RIDE

在命令行输入ride.py并回车，便可启动RIDE

安装pygments

Text Edit的tab提示需要安装高亮显示用的包pygments

使用pip install pygments进行安装

liumiaocn:~ liumiao$ pip install pygments
Collecting pygments

liumiaocn:~ liumiao$

再次启动ride.py，已经可以正常动作了。
