  • pytest学习(1)

    pytest是python的一个测试框架,主要是用来进行一些小的测试。

    在pycharm中,缺省用的是unittest,这里说明如何设置为pytest。

    当然,第一部是安装pytest

    pip3 install pytest

    然后,在pycharm中,files-》settings-》tools=》python integrated tools=》设定default test runner

    然后,写一个简单的py程序(记住,test_*.py or *_test.py):

    def inc(x):
        return x + 1
    
    def test_answer():
        assert inc(3) == 5
    
    def test_wcf():
        assert inc(3) > 5
    
    def test_hy():
        assert inc(3) < 5
    

      运行后:

    C:Python35python.exe C:UserswcfAppDataLocalJetBrainsToolboxappsPyCharm-Pch-0171.4694.67helperspycharm\_jb_pytest_runner.py --path C:/fitme/work/nltk/test_5.py

    E       assert 4 == 5
    E        +  where 4 = inc(3)
    
    test_5.py:5: AssertionError

    test_5.py:6 (test_wcf)
    def test_wcf():

    E       assert 4 > 5
    E        +  where 4 = inc(3)
    
    test_5.py:8: AssertionError
    .

    E        +  where 4 = inc(3)
    
    test_5.py:8: AssertionError
    ===================== 2 failed, 1 passed in 0.05 seconds ======================
    
    Process finished with exit code 0
    

     如果只运行pytest,则对当前目录下所有的test_*.py or *_test.py文件都进行测试。
