如何使用Robot Framework在控制台输出中放置颜色 [英] How can I put colors in console output with Robot Framework

问题描述

我想在RobotFramework的控制台输出中添加一些颜色。

I would like to put some colors in the console output of RobotFramework.

我尝试使用控制台颜色代码，例如：

I tried to use the console color codes like:

${message}=  Set Variable  hello world!
Log To Console  \\e[0;36;49m${message}\\e[0;39;49m

（在Linux控制台中， echo -e \e [0; 36; 49mHello world！\e [0; 39; 49m 打印 Hello world！青色）

(In a linux console, echo -e "\e[0;36;49mHello world!\e[0;39;49m" print Hello world! in cyan)

（我也尝试过使用一个 \ 以及 \033 [31m，\033 [0m，... 代码）

(I also tried with one \ and also \033[31m, \033[0m, ... codes)

但是它不起作用...

But it doesn't work...

因此，是否有可能执行以下操作：

So, is it possible to do something like:

${message}=  Set Variable  hello world!
Log To Console ${message.red}

我发现此模块，但我没有找到有关使用方法的任何信息它：（

I found this module but I didn't found anything on how to use it :(

我尝试过：

Log To Console ${message.red}  robot.output.console.highlighting

和

${message}=  Evaluate  ${message}.red  robot.output.console.highlighting
Log To Console ${message}

但没有效果：'（

推荐答案

由于机器人框架对 \的解释，登录控制台\\033 [31mRed文本\\033 [0m ]为输出着色。

Because of Robot Framework interpretation of '\', Log To Console \\033[31mRed Text\\033[0m doesn't color the output.

要解决此问题，必须登录变量 Evaluate 才能登录控制台：

To solve this problem, you have to Evaluate the variable before to log in to console:

${message}=  Evaluate  "\\033[31mRed Text\\033[0m"
Log To Console  ${message}

我最终获得了以下内容解决方案，我觉得它很干净：

I ended up with the below solution, which I find quite "clean":

*** Variables ***
${BLACK}  "\\033[30m"
${RED}    "\\033[31m"
# More colors ANSI codes...

*** Keywords ***
Initialize Colors
  ${black}=  Evaluate  ${BLACK}
  Set Test Variable  ${black}
  ${red}=  Evaluate  ${RED}
  Set Test Variable  ${red}
  # More colors...

然后，您只需在套件/测试用例设置中使用上一个关键字，您就可以为输出着色，如下所示：

Then, you just have to use the previous keyword in a Suite/Test Case Setup and you can colorize your outputs like below:

Log To Console  ${cyan}Some Text in cyan and a ${red}${variable}${cyan} in red${default}
