首先来个截图。

green是unittest 众多runner中功能比较丰富的一个。

官方的featrue介绍如下：

Clean - Low redundancy in output. Result statistics for each test is vertically aligned.
Colorful - Terminal output makes good use of color when the terminal supports it.
Fast - Tests run in independent processes. (One per processor by default. Does not play nicely with gevent)
Powerful - Multi-target + auto-discovery.
Traditional - Use the normal unittest classes and methods for your unit tests.
Descriptive - Multiple verbosity levels, from just dots to full docstring output.
Convenient - Bash-completion and ZSH-completion of options and test targets.
Thorough - Built-in integration with coverage.
Embedded - Can be run with a setup command without in-site installation.
Modern - Supports Python 3.5+. Additionally, PyPy is supported on a best-effort basis.
Portable - macOS, Linux, and BSDs are fully supported. Windows is supported on a best-effort basis.
Living - This project grows and changes. See the changelog

简单来说，green的一些优势有：

• 简单高效
• 命令行输出支持各种高亮
• 一直在维护
• 支持python3
• 集成了代码覆盖率

安装

pip install green

简单使用

我们可以用官方的例子来简单玩一下。

git clone https://github.com/CleanCut/green.git
cd green/example/proj
green -vvv --run-coverage

运行结果

Green 3.0.0, Coverage 4.5.4, Python 2.7.15

proj.test.test_foo
  TestAnswer
.   answer() returns 42
.   answer() returns an integer
  TestSchool
.   test_age
.   test_food

Ran 4 tests in 0.123s using 8 processes

OK (passes=4)

因为我是纯文本贴出来的，所以没能体现出高亮的效果。大家可以自己试着运行一下，在mac上还是很好看的。windows上表现怎么样还不是很清楚。

适用场景

• green支持跟django集成，可以替换django的默认testrunner
• green支持的配置很多，可以敲green -h来看，可以作为自己测试项目的基础框架，从而实现更多功能
