1. 简介
nose是python开发的测试框架。nose扩展了unittest，他让测试更加容易。
1.1 编写用例更简单
nose可以收集继承于unittest.TestCase类中的测试例，当然，你也可以编写简单的测试函数，编写并不是继承于unittest.TestCase的测试类。nose也提供了许多帮助函数，用于编写定时测试例，用于异常的测试，和其他一些公共的使用情况。
1.2 运行用例更简单
只要你按照一些简单的要求组织你的测试库和代码，nose就可以自动收集测试用例。并没有必要手动收集测试case到测试suites中。运行测试响应迅速，因为nose在加载第一个测试模块后立即开始运行测试
1.3 初始化测试环境更简单
nose组件支持package，module，class和case级别，因此初始化操作很容易完成。
1.4 做所想的事更简单
nose配备了一些内置插件，以帮助你捕获输出，反思错误，覆盖代码，文档测试，等等。它还配备了用于加载、运行测试，在测试例运行时，查看和报告测试。如果您不喜欢默认收集方案，或者它不适合你的项目，或者你需要不同于unittest标准的格式报告，或者需要收集有关测试的额外信息（如代码覆盖或数据分析），您可以编写插件来让nose做这些事。

注意：nose支持python3，但nose下的部分第三方插件本不支持python3，所以使用的时候要注意，本文中提到的均为python3
3. nose命令
nosetests -h
Usage: nosetests [options]
Options:
-h, --help show this help message and exit
-V, --version Output nose version and exit
-p, --plugins Output list of available plugins and exit. Combine
with higher verbosity for greater detail
-v, --verbose Be more verbose. [NOSE_VERBOSE]
--verbosity=VERBOSITY
Set verbosity; --verbosity=2 is the same as -v
-q, --quiet Be less verbose
-c FILES, --config=FILES
Load configuration from config file(s). May be
specified multiple times; in that case, all config
files will be loaded and combined
-w WHERE, --where=WHERE
Look for tests in this directory. May be specified
multiple times. The first directory passed will be
used as the working directory, in place of the current
working directory, which is the default. Others will
be added to the list of tests to execute. [NOSE_WHERE]
--py3where=PY3WHERE Look for tests in this directory under Python 3.x.
Functions the same as 'where', but only applies if
running under Python 3.x or above. Note that, if
present under 3.x, this option completely replaces any
directories specified with 'where', so the 'where'
option becomes ineffective. [NOSE_PY3WHERE]
-m REGEX, --match=REGEX, --testmatch=REGEX
Files, directories, function names, and class names
that match this regular expression are considered
tests. Default: (?:^|[\b_\.\-])[Tt]est
[NOSE_TESTMATCH]
--tests=NAMES Run these tests (comma-separated list). This argument
is useful mainly from configuration files; on the
command line, just pass the tests to run as additional
arguments with no switch.
-l DEBUG, --debug=DEBUG
Activate debug logging for one or more systems.
Available debug loggers: nose, nose.importer,
nose.inspector, nose.plugins, nose.result and
nose.selector. Separate multiple names with a comma.
--debug-log=FILE Log debug messages to this file (default: sys.stderr)
--logging-config=FILE, --log-config=FILE
Load logging config from this file -- bypasses all
other logging config settings.
-I REGEX, --ignore-files=REGEX
Completely ignore any file that matches this regular
expression. Takes precedence over any other settings
or plugins. Specifying this option will replace the
default setting. Specify this option multiple times to
add more regular expressions [NOSE_IGNORE_FILES]
-e REGEX, --exclude=REGEX
Don't run tests that match regular expression
[NOSE_EXCLUDE]
-i REGEX, --include=REGEX
This regular expression will be applied to files,
directories, function names, and class names for a
chance to include additional tests that do not match
TESTMATCH. Specify this option multiple times to add
more regular expressions [NOSE_INCLUDE]
-x, --stop Stop running tests after the first error or failure
-P, --no-path-adjustment
Don't make any changes to sys.path when loading tests
[NOSE_NOPATH]
--exe Look for tests in python modules that are executable.
Normal behavior is to exclude executable modules,
since they may not be import-safe [NOSE_INCLUDE_EXE]
--noexe DO NOT look for tests in python modules that are
executable. (The default on the windows platform is to
do so.)
--traverse-namespace Traverse through all path entries of a namespace
package
--first-package-wins, --first-pkg-wins, --1st-pkg-wins
nose's importer will normally evict a package from
sys.modules if it sees a package with the same name in
a different location. Set this option to disable that
behavior.
--no-byte-compile Prevent nose from byte-compiling the source into .pyc
files while nose is scanning for and running tests.
-a ATTR, --attr=ATTR Run only tests that have attributes specified by ATTR
[NOSE_ATTR]
-A EXPR, --eval-attr=EXPR
Run only tests for whose attributes the Python
expression EXPR evaluates to True [NOSE_EVAL_ATTR]
-s, --nocapture Don't capture stdout (any stdout output will be
printed immediately) [NOSE_NOCAPTURE]
--nologcapture Disable logging capture plugin. Logging configuration
will be left intact. [NOSE_NOLOGCAPTURE]
--logging-format=FORMAT
Specify custom format to print statements. Uses the
same format as used by standard logging handlers.
[NOSE_LOGFORMAT]
--logging-datefmt=FORMAT
Specify custom date/time format to print statements.
Uses the same format as used by standard logging
handlers. [NOSE_LOGDATEFMT]
--logging-filter=FILTER
Specify which statements to filter in/out. By default,
everything is captured. If the output is too verbose,
use this option to filter out needless output.
Example: filter=foo will capture statements issued
ONLY to foo or foo.what.ever.sub but not foobar or
other logger. Specify multiple loggers with comma:
filter=foo,bar,baz. If any logger name is prefixed
with a minus, eg filter=-foo, it will be excluded
rather than included. Default: exclude logging
messages from nose itself (-nose). [NOSE_LOGFILTER]
--logging-clear-handlers
Clear all other logging handlers
--logging-level=LOGCAPTURE_LEVEL
Set the log level to capture
--with-coverage Enable plugin Coverage: Activate a coverage report
using Ned Batchelder's coverage module.
[NOSE_WITH_COVERAGE]

Restrict coverage output to selected packages
[NOSE_COVER_PACKAGE]
--cover-erase Erase previously collected coverage statistics before
run
--cover-tests Include test modules in coverage report
[NOSE_COVER_TESTS]
--cover-min-percentage=COVER_MIN_PERCENTAGE
Minimum percentage of coverage for tests to pass
[NOSE_COVER_MIN_PERCENTAGE]

--with-doctest Enable plugin Doctest: Activate doctest plugin to
find and run doctests in non-test modules.
[NOSE_WITH_DOCTEST]
--doctest-tests Also look for doctests in test modules. Note that
classes, methods and functions should have either
doctests or non-doctest tests, not both.
[NOSE_DOCTEST_TESTS]
--doctest-extension=EXT
Also look for doctests in files with this extension
[NOSE_DOCTEST_EXTENSION]
--doctest-result-variable=VAR
Change the variable name set to the result of the last
interpreter command from the default '_'. Can be used
to avoid conflicts with the _() function used for text
translation. [NOSE_DOCTEST_RESULT_VAR]

resets the contents of sys.modules after each test
module or package runs to its state before the test.
PLEASE NOTE that this plugin should not be used with
the coverage plugin, or in any other case where module
reloading may produce undesirable side-effects.
[NOSE_WITH_ISOLATION]
-d, --detailed-errors, --failure-detail
Add detail to error output by attempting to evaluate
failed asserts [NOSE_DETAILED_ERRORS]
--no-skip Disable special handling of SkipTest exceptions.
--with-id Enable plugin TestId: Activate to add a test id (like
#1) to each test name output. Activate with --failed
to rerun failing tests only. [NOSE_WITH_ID]
--id-file=FILE Store test ids found in test runs in this file.
Default is the file .noseids in the working directory.
--failed Run the tests that failed in the last test run.
--processes=NUM Spread test run among this many processes. Set a
number equal to the number of processors or cores in
your machine for best results. Pass a negative number
to have the number of processes automatically set to
the number of cores. Passing 0 means to disable
parallel testing. Default is 0 unless NOSE_PROCESSES
is set. [NOSE_PROCESSES]
--process-timeout=SECONDS
Set timeout for return of results from each test
runner process. Default is 10. [NOSE_PROCESS_TIMEOUT]
--process-restartworker
If set, will restart each worker process once their
tests are done, this helps control memory leaks from
killing the system. [NOSE_PROCESS_RESTARTWORKER]
--with-xunit Enable plugin Xunit: This plugin provides test results
in the standard XUnit XML format. [NOSE_WITH_XUNIT]
--xunit-file=FILE Path to xml file to store the xunit report in. Default
is nosetests.xml in the working directory
[NOSE_XUNIT_FILE]
--xunit-testsuite-name=PACKAGE
Name of the testsuite in the xunit xml, generated by
plugin. Default test suite name is nosetests.
--all-modules Enable plugin AllModules: Collect tests from all
python modules. [NOSE_ALL_MODULES]
--collect-only Enable collect-only: Collect and output test names
only, don't run any tests. [COLLECT_ONLY]
4. 基本用法
使用notetests脚本
nosetests [options] [(optional) test files or directories]
除了使用命令行参数外，你还可以在测试目录下配置.noserc或者nose.cfg文件。该配置文件是标准的.ini配置文件。把你的配置写在[nosetests]部分，如下：
[nosetests]
verbosity=3
with-doctest=1
也有不能使用配置文件的情况（如运行nose时你不想让使用nose的全局配置文件）。为了忽略这个配置文件，我们可以设置一个环境变量NOSE_IGNORE_CONFIG_FILES。
除了使用notetests外，我们还可以使用其他方法运行nose，如下：
import nose
nose.main()
如果你不想使用unittest框架测试结束时这种显示方式，可以在脚本中使用以下方式：
import nose
result = nose.run()
4.1 nose测试实践
- 函数形式的测试用例
#coding:utf-8
def setUp():
print("test_setUp")
def test_task_1():
print("test_task_1")
def test_task_2():
print("test_task_2")
def test_task_3():
print("test_task_3")
def tearDown():
print("test_teardown")
test_task_1.teardown=test_task_3.teardown= tearDown
运行的结果如下：
PS C:\Users\dell\Desktop\test\nose> nosetests -v -s test_case.test_case_1
test_setUp
test_case_1.test_task_1 ... test_task_1
test_teardown
ok
test_case_1.test_task_2 ... test_task_2
ok
test_case_1.test_task_3 ... test_task_3
test_teardown
ok
test_teardown
----------------------------------------------------------------------
Ran 3 tests in 0.002s
OK
最后面加了一句test_task_1.teardown=test_task_3.teardown= tearDown，说明在运行完成后就执行tearDown操作，所以这里的执行顺序是：setUp-->test_task_1-->teardown-->test_task_2-->test_task_3-->teardown-->teardown
因次，在函数或者函数式的用例组织中，setUp和tearDown只会执行一次，分别是开始及结束。
- 类形式的测试用例
# coding=utf-8
class TestClass():
def setUpClass():
print("TestClass.setUpClass")
def setUp(self):
print("TestClass.setup")
def Testfunc1(self):
print("TestClass.Testfunc1")
def test_func1(self):
print("TestClass.test_func1")
def Testfunc2(self):
print("TestClass.Testfunc2")
def test_func2(self):
print("TestClass.test_func2")
def tearDown(self):
print("TestClass_setup_teardown")
def tearDownClass():
print("TestClass.tearDownClass")
运行结果：
PS C:\Users\dell\Desktop\test\nose> nosetests -v -s test_case.test_case_2
TestClass.setUpClass
test_case_2.TestClass.Testfunc1 ... TestClass.setup
TestClass.Testfunc1
TestClass_setup_teardown
ok
test_case_2.TestClass.Testfunc2 ... TestClass.setup
TestClass.Testfunc2
TestClass_setup_teardown
ok
test_case_2.TestClass.test_func1 ... TestClass.setup
TestClass.test_func1
TestClass_setup_teardown
ok
test_case_2.TestClass.test_func2 ... TestClass.setup
TestClass.test_func2
TestClass_setup_teardown
ok
TestClass.tearDownClass
----------------------------------------------------------------------
Ran 4 tests in 0.003s
OK
从运行结果中可以看出，每个用例都会分别执行setUp及tearDown，但是与unittest一样，在类中的测试用例顺序变更了，由字母排序了。而setUpClass和tearDownClass两个函数功能，只运行一次。
- 包形式运行
我们创建包的时候需要同时新建__init__.py，添加内容如下：
def setUp():
print("全部开始")
def tearDown():
print("全部结束")
然后再次执行包文件，结果如下：
PS C:\Users\dell\Desktop\test\nose> nosetests -v -s test_case.test_case_2
全部开始
TestClass.setUpClass
test_case.test_case_2.TestClass.Testfunc1 ... TestClass.setup
TestClass.Testfunc1
TestClass_setup_teardown
ok
test_case.test_case_2.TestClass.Testfunc2 ... TestClass.setup
TestClass.Testfunc2
TestClass_setup_teardown
ok
test_case.test_case_2.TestClass.test_func1 ... TestClass.setup
TestClass.test_func1
TestClass_setup_teardown
ok
test_case.test_case_2.TestClass.test_func2 ... TestClass.setup
TestClass.test_func2
TestClass_setup_teardown
ok
TestClass.tearDownClass
全部结束
----------------------------------------------------------------------
Ran 4 tests in 0.002s
OK
从结果中可以看出，在执行前执行了__init__.py中的setUp函数，在执行最后执行了teardown函数。
- with_setup修饰器
nose支持在每个用例前使用with_setup来自定义测试用例的setUp及tearDown功能，如下：
# coding=utf-8
from nose.tools import with_setup
def setup_func():
print("set up test fixtures")
def teardown_func():
print("tear down test fixtures")
@with_setup(setup_func, teardown_func)
def test_1():
print("test_1")
def test_2():
print("test_2")
test_2.setup = setup_func
test_2.teardown = teardown_func
运行结果：
PS C:\Users\dell\Desktop\test\nose> nosetests -v -s test_case.test_case_3
全部开始
test_case.test_case_3.test_1 ... set up test fixtures
test_1
tear down test fixtures
ok
test_case.test_case_3.test_2 ... set up test fixtures
test_2
tear down test fixtures
ok
全部结束
----------------------------------------------------------------------
Ran 2 tests in 0.002s
OK
除了with_setup的方法@with_setup(setup_func, teardown_func)，还可以这样写
test_2.setup = setup_func
test_2.teardown = teardown_func
- 多文件执行nose
如下，有三个可执行的文件
test_case
|--__init__.py
|--test_case_1.py
|--test_case_2.py
|--test_case_3.py
运行结果：
PS C:\Users\dell\Desktop\test\nose> nosetests -w test_case test_case_2
....
----------------------------------------------------------------------
Ran 4 tests in 0.001s
OK
4.2 nose运行方式
unittest 所支持的用例发现和执行能力，nose 均支持。 nose 支持用例自动（递归）发现：
默认发现当前目录下所有包含 test 的测试用例，但不包括以 _ 开头的用例，使用 nosetests 命令，通过 -w 参数指定要自动发现的目录， -m 参数指定用例文件、目录、函数、类的名称模式（正则匹配），nosetests -w project_directory "test_.+"。
nose 也支持执行指定用例：
- 指定测试模块
nosetests test_case.test_case_1
- 指定测试类
nosetests test_case.test_case_2:TestClass
- 指定测试方法
nosetests test_case.test_case_2:TestClass.Testfunc1
- 指定测试文件路径
nosetests C:/Users/dell/Desktop/test/nose/test_case/test_case_1.py
- 指定测试文件路径+测试类或测试函数（这是
unittest所不支持的）
nosetests C:/Users/dell/Desktop/test/nose/test_case/test_case_2.py:TestClass
nosetests C:/Users/dell/Desktop/test/nose/test_case/test_case_2.py:TestClass.Testfunc1
nosetests C:/Users/dell/Desktop/test/nose/test_case/test_case_1.py:test_task_1
5. 子测试/测试生成器
nose 除了支持 unittest 中的 TestCase.subTest，还支持一种更为强大的子测试编写方式，也就是 测试生成器（Test generators），通过 yield 实现。
在下面的示例中，定义一个 test_evens 测试函数，里面生成了 5 个子测试 check_even：
def test_evens():
for i in range(0, 5):
yield check_even, i, i*3
def check_even(n, nn):
assert n % 2 == 0 or nn % 2 == 0
此外，相较于 unittest.TestCase.subTest 多个子测试只能执行一次测试前置和清理，nose的 测试生成器 可以支持每个子测试执行一次测试前置和清理，如：
def test_generator():
# ...
yield func, arg, arg # ...
@with_setup(setup_func, teardown_func)
def func(arg):
assert something_about(arg)
如下是一个例子：
# coding=utf-8
def setUp():
print('testSetUp')
def tearDown():
print('testTearDown')
def test_evens():
for i in range(0, 5):
yield check_even, i, i*3
def check_even(n, nn):
assert n % 2 == 0 or nn % 2 == 0
运行结果：
PS C:\Users\dell\Desktop\test\nose> nosetests -v -s test_case.test_case_5
全部开始
testSetUp
test_case.test_case_5.test_evens(0, 0) ... ok
test_case.test_case_5.test_evens(1, 3) ... FAIL
test_case.test_case_5.test_evens(2, 6) ... ok
test_case.test_case_5.test_evens(3, 9) ... FAIL
test_case.test_case_5.test_evens(4, 12) ... ok
testTearDown

6. nose的测试工具集
nose.tools模块提供了一系列的小工具，包括测试执行时间、异常输出及unittest框架中所有的assert功能。
为了使写用例更加容易，nose.tools提供了部分便利的功能函数，下面写几个常用的，如下：
6.1 nose.tools.ok_(expr, msg=None)
标准的assert，例子如下：
from nose.tools import ok_
def test_lean_2():
print "test_case_2"
ok_(4==3,msg="Error")
运行结果如下：
PS C:\Users\dell\Desktop\test\nose> nosetests -v test_case.test_case_4:test_task_1
test_case.test_case_4.test_task_1 ... FAIL

from nose.tools import assert_in
from nose.tools import set_trace
def test_task_4():
set_trace()
assert_in("aaa",'bbb',msg="test in failed")

7. 插件
nose 相较于 unittest 一个最大的优势就是插件体系，自带了很多有用的插件，也有丰富的第三方插件。这样就能做更多的事情。
其中，自带插件如下：
- AllModules：在所有模块中收集用例。
- Attrib：给用例打标签，并可运行含指定标签的用例
- Capture：捕获用例的标准输出
- Collect：快速收集用例
- Cover：统计代码覆盖率
- Debug：用例失败时进入 pdb 调试
- Deprecated：标记用例为弃用
- Doctests：运行文档用例
- Failure Detail：断言失败时提供上下文信息
- Isolate：保护用例避免受一些副作用的影响
- Logcapture：捕捉 logging 输出
- Multiprocess：并行执行用例
- Prof：使用热点分析器进行分析
- Skip：标记用例为跳过
- Testid：为输出的每个用例名称添加测试 ID
- Xunit：以 xunit 格式输出测试结果
还有很多第三方库，如用来生成 HTML 格式测试报告的 nose-htmloutput 等，这里不再赘述。
nose 得益于丰富的插件生态，当 nose 本身不能够完全满足我们的测试需求时，可以通过安装插件，并在 nosetests 命令行指定该插件所提供的特定参数即可非常容易的使用插件。 相较于 unittest，就能省去很多自己开发额外测试逻辑的精力。
