项目介绍

从oracle迁移数据到mysql

• 代码位置： db/oracle 文件：config.py transfer_db.py

• 测试环境：CentOS release 6.6 (Final) 64 python2.7

• 运行依赖： python外部库cx_Oracle、mysql-connector-python

• 功能：迁移oracle数据到mysql，需要先行在mysql创建表。特别注意，有清空mysql表的动作。

python批量清空数据库

• 简介：使用python批量清空数据库，基于mysql python api和python标准库configparser，实现可配置地批量清空mysql表。

• 支持版本：python2.7/3.*

• 后期规划：通过argparse支持指定配置文件，增加delete、truncate、rename等选项。

• 代码 db/mysql del_db.py db.conf

在oracle中插入假数据

• 简介：在oracle中插入假数据

• 测试环境：CentOS release 6.6 (Final) 64 python2.7

• 代码 db/oracle oracle_add.py

简介

pytest是强大的python单元测试框架。由于python的胶水语言特性，实质上pytest在接口测试、自动化测试等方面也广泛使用。

• 成熟全功能的Python测试工具

  • 支持POSIX / Windows， Python的2.6-3.5， PyPy和Jython - 2.5.1(也可能支持更高版本)
  • 免费、开源，基于MIT license
  • 1000测试用例自测。
  • pytest升级时有很好的向后兼容性
  • 丰富的在线和PDF文档 comprehensive onlinePDF documentation
  • 大量的第三方插件和内置帮助builtin helpers, third party plugins
  • 在许多小型和大型项目和组织使用，many small and large projects and organisations
  • 许多测试实例，tested examples

• 灵活

  • 易学，有多种用法
  • assert语句断言
  • traceback 和失败断言报告
  • 打印调试和测试执行期间可以捕获标准输出

• 适合简单的单元测试到复杂的功能测试

  • 模块化和参数化的平台
  • 参数化的测试函数

入门基础

使用和调用

• python -m pytest调用：

  • python -m pytest [...] 效果和py.test [...] 一样

• 获取版本，选项名，环境变量

  • py.test --version 看版本
  • py.test --fixtures 查看内置函数参数
  • py.test -h | --help 命令行和配置文件帮助

• 失败后停止执行

  • 首次失败后停止执行：py.test -x
  • py.test --maxfail=2 两次失败之后停止执行

• 执行选择用例

  • py.test test_mod.py，执行模块中的用例
  • py.test somepath，执行路径中用例
  • py.test -k stringexpr，执行字符串表达式中的用例，比如"MyClass and not method""，选择TestMyClass.test_something，排除了TestMyClass.test_method_simple。
  • py.test --pyargs pkg，导入pkg，使用其文件系统位置来查找和执行用例。执行pypkg目录下的所有用例。
  • py.test test_mod.py::test_func  指定模块和函数
  • py.test test_mod.py::TestClass::test_method 指定模块和类及方法

• 调试输出：

  • py.test --showlocals 在traceback中显示本地变量
  • py.test -l 在traceback中显示本地变量（快捷方式）
  • py.test --tb=auto 默认格式，首尾为long，其他为short
  • py.test --tb=long 详细的traceback信息格式化形式
  • py.test --tb=native 标准库格式化形式
  • py.test --tb=short 更短的traceback格式
  • py.test --tb=line 每个错误一行
  • py.test --tb=no 无traceback
  • py.test --full-trace 最详细的格式

• 失败时调用PDB (Python Debugger)：

Python带有一个内置的Python调试器称为PDB。pytest可以在命令行选项指定调用：

py.test --pdb

这将每次失败时调用Python调试器。

py.test -x --pdb # 失败时调用pdb，然后退出测试。 py.test --pdb - maxfail=3＃ 前3次失败调用pdb。

异常信息保存在sys.last_value, sys.last_type和``sys.last_traceback，交互式情况可以调试：

>>> import sys
>>> sys.last_traceback.tb_lineno
42
>>> sys.last_value
AssertionError('assert result == "ok"',)

• 设置断点：

import pytest
def test_function():
    ...
    pytest.set_trace()    # invoke PDB debugger and tracing

2.0.0以前的版本中只有通过py.test-s禁用命令行捕捉才可以进入pdb调试。2.0.0及以后版本在进入pdb调试时自动禁用输出捕捉。

2.4.0 支持使用importpdb;pdb.set_trace()进入pdb。

• Profiling测试执行时间：得到最执行慢的10个测试：

py.test --durations=10

• 创建JUnitXML格式的文件

创建Jenkins或其他持续集成服务器的结果文件：

py.test --junitxml=path

• record_xml_property

2.8新增

在xml文件中记录额外信息

def test_function(record_xml_property):
    record_xml_property("example_key", 1)
    assert 0

效果如下：

试验功能，与pytest-xdist不兼容，还有可能破坏模式验证，与一些CI集成可能会有问题。

• 创建resultlog格式的文件

要创建纯文本的机器可读的结果文件，用于PyPy-testweb展示等。

py.test --resultlog=path

• 发送测试报告给在线pastebin服务

bpaste可以为你的文本生成url连接，下面为创建每个测试失败创建一个url：

py.test --pastebin=failed

py.test --pastebin=all py.test --pastebin=failed -x　# 只发送一次

目前只支持：http://bpaste.net

• 禁用插件

  py.test -p no:doctest

• 在python代码中调用pytest

  2.0新增　用exitcode代替了SystemExit。 pytest.main([’-x’, ’mytestdir’]) pytest.main("-x mytestdir")

  # 指定插件

  # content of myinvoke.py
  import pytest
  class MyPlugin:
      def pytest_sessionfinish(self):
          print("*** test run reporting finishing")
  
  pytest.main("-qq", plugins=[MyPlugin()])
  

执行结果：

$ python myinvoke.py
*** test run reporting finishing

好的集成实践

• 使用虚拟环境

#virtualenv . New python executable in ./bin/python Installing setuptools, pip...done. root@AutoTest:[/data/code/python/pytest]#source bin/activate (pytest)root@AutoTest:[/data/code/python/pytest]#pip install pytest Downloading/unpacking pytest Downloading pytest-2.5.2.tar.gz (608kB): 608kB downloaded Running setup.py (path:/data/code/python/pytest/build/pytest/setup.py) egg_info for package pytest

• 测试布局和导入规则

测试布局的方法有2种。一为放置在应用代码之外，适用于有很多功能测试等情况。

setup.py # your distutils/setuptools Python package metadata mypkg/ __init__.py appmodule.py tests/ test_app.py ...

二为嵌入测试目录到应用，当(单元)测试和应用之间的有直接关系，并想一起发布时有用：

setup.py # your distutils/setuptools Python package metadata mypkg/ __init__.py appmodule.py ... test/ test_app.py

部分使用pytest的项目

参见：Project examples

使用与实例

http://stackoverflow.com/search?q=pytest 上有很多例子。

断言

简单断言

# content of test_assert1.py
def f():
    return 3

def test_function():
    assert f() == 4

执行结果：

$ py.test test_assert1.py

• 异常断言

import pytest

def test_zero_division():
    with pytest.raises(ZeroDivisionError):
        1 / 0

获取异常信息：

def test_recursion_depth():
    with pytest.raises(RuntimeError) as excinfo:
        def f():
            f()
        f()
    assert 'maximum recursion' in str(excinfo.value)

xfail中也可以指定异常类型：

import pytest

@pytest.mark.xfail(raises=NameError)
def test_f():
    f()

pytest.raises适用于故意产生异常，@pytest.mark.xfail适用于处理bug。

上下文比较

# content of test_assert2.py def test_set_comparison(): set1 = set("1308") set2 = set("8035") assert set1 == set2

基本模式和实例

命令行传参数

下面函数中的cmdopt，需要从命令行读取：

# content of test_sample.py
def test_answer(cmdopt):
    if cmdopt == "type1":
        print ("first")
    elif cmdopt == "type2":
        print ("second")
    assert 0 # to see what was printed

设置_conftest.py_

# content of conftest.py
import pytest

def pytest_addoption(parser):
    parser.addoption("--cmdopt", action="store", default="type1",
        help="my option: type1 or type2")

下面用例，如果打了slow标签，则会需要添加选项--runslow才能执行。

配置

# content of conftest.py

import pytest
def pytest_addoption(parser):
    parser.addoption("--runslow", action="store_true",
        help="run slow tests")

用例：

# content of test_module.py

Fixture

python中经典的xunit风格的setup是2005年首先出现在pytest，后面被nose和unittest采用。建议优先使用fixture，因为它有依赖注入，更强大。

• 模块级别

def setup_module(module):
    """ setup any state specific to the execution of the given module."""

def teardown_module(module):
    """ teardown any state that was previously setup with a setup_module
    method.
    """

• 类级别

​

@classmethod
def setup_class(cls):
    """ setup any state specific to the execution of the given class (which
    usually contains tests).
    """

@classmethod
def teardown_class(cls):
    """ teardown any state that was previously setup with a call to
    setup_class.
    """

​

• 方法和函数级别

​

@classmethod
def setup_class(cls):
    """ setup any state specific to the execution of the given class (which
    usually contains tests).
    """

@classmethod
def teardown_class(cls):
    """ teardown any state that was previously setup with a call to
    setup_class.
    """

​ ​

def setup_function(function):
    """ setup any state tied to the execution of the given function.
    Invoked for every test function in the module.
    """

def teardown_function(function):
    """ teardown any state that was previously setup with a setup_function
    call.
    """

​

临时目录和文件

tmpdir fixture

tmpdir是py.path.local对象，提供了os.path等的方法。

test_tmpdir.py

# content of test_tmpdir.py

生成的目录一般在系统临时目录下面，格式为pytest-NUM，比如/tmp/pytest-of-andrew/pytest-0/test_create_file0，每次测试执行时NUM会增加，3个以前的目录会清除。如下方式会指定为其他目录：py.test --basetemp=mydir。

tmpdir_factory fixture

2.8新增

tmpdir_factory基于session，可创建任意临时目录。

例如，假设test suite需要大文件：

# contents of conftest.py
import pytest

@pytest.fixture(scope='session')
def image_file(tmpdir_factory):
    img = compute_expensive_image()
    fn = tmpdir_factory.mktemp('data').join('img.png')
    img.save(str(fn))
    return fn

# contents of test_image.py
def test_histogram(image_file):
    img = load_image(image_file)
    # compute and test histogram

相关方法：

TempdirFactory.``mktemp(basename, numbered=True)[source]

TempdirFactory.``getbasetemp()[source]

捕捉输出

默认stdout/stderr/stdin捕捉行为

默认捕捉stdout/stderr，如果test或者setup方法失败，traceback会打印相关内容。

stdin为null，读取会报错，因为自动化测试鲜有交互式输入。

默认捕捉为写入到底层文件，可以捕捉print语言输出到test中的subprocess输出。

设置捕捉

默认捕捉方式为file descriptor (FD)级捕捉。捕捉所有到操作系统的1,2输出。

syslevel级捕捉只捕捉python的sys.stdout和sys.stderr。

py.test -s            # disable all capturing
py.test --capture=sys # replace sys.stdout/stderr with in-mem files
py.test --capture=fd  # also point filedescriptors 1 and 2 to temp file

使用print进行调试　

默认捕捉stdout/stderr：

# content of test_module.py

def setup_function(function):
    print ("setting up %s" % function)

def test_func1():
    assert True

def test_func2():
    assert False

执行结果：
