如何使用Atom编辑器运行Python单元测试？

Question

我正在尝试使用Atom编辑器，并想知道如何使用键盘快捷键运行Python单元测试。

Answer 1

Installation

1. Install the Atom editor

2. Install the Script package like this:

   a) Start Atom

   b) Press Ctrl + Shift + P , type "install packages and themes" and press Enter to open the package view

   c) Search for "script" and install the package

Unit test example test.py

3. Write a unit test and save it as test.py .

    import unittest class MyTest(unittest.TestCase): def test_pass(self): pass def test_fail(self): call_method_that_does_not_exist() if __name__ == '__main__': unittest.main() 

Run unit test

4. Now, press Ctrl + I to run the Python script ( see documentation )

Console output

Because the unit test test_fail will fail, this will be the console output:

E.
======================================================================
ERROR: test_fail (__main__.MyTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/Lernkurve/Desktop/PythonDemos/a.py", line 9, in test_fail
    call_method_that_does_not_exist()
NameError: global name 'call_method_that_does_not_exist' is not defined

Answer 2

You could use the Atom Python Test plug-in. It supports:

• Run the test under cursor
• Run all tests of a module
• Run doc tests

It also supports adding additional arguments to test execution and allows to run unitttest.TestCase too.
