assert

https://github.com/ActivisionGameScience/assertpy assertpy是基于python的断言库 简介 安装 pip install assertpy 引用 from assertpy import assert_that 可用于python的pytest、nose等单元测试框架 可用于断言strings、numbers、lists、tuples、dicts、sets、Booleans、dates、files、object等 匹配字符串 类型判断 assert_that(’’).is_not_none()#不是null assert_that(’’).is_empty()#是空 assert_that(’’).is_false()#是false assert_that(’’).is_type_of(str)#是str的类型 assert_that(’’).is_instance_of(str)#是str的实例 常用 assert_that(‘foo’).is_length(3)#字符串长度是3 assert_that(‘foo’).is_not_empty()#不是空的 assert_that(‘foo’).is_true()#是true assert_that(‘foo’).is_alpha()#是字母 assert_that(

Could you give an example where static_assert(...) 'C++0x' would solve the problem in hand elegantly? I am familiar with run-time assert(...) . When should I prefer static_assert(...) over regular assert(...) ? Also, in boost there is something called BOOST_STATIC_ASSERT , is it the same as static_assert(...) ? Off the top of my head... #include "SomeLibrary.h" static_assert(SomeLibrary::Version > 2, "Old versions of SomeLibrary are missing the foo functionality. Cannot proceed!"); class UsingSomeLibrary { // ... }; Assuming that SomeLibrary::Version is declared as a static const, rather than

What does assert mean in JavaScript? I’ve seen something like: assert(function1() && function2() && function3(), "some text"); And would like to know what the method assert() does. There is no assert in JavaScript (yet; there's talk of adding one , but it's at an early stage). Perhaps you're using some library that provides one. The usual meaning is to throw an error if the expression passed into the function is false; this is part of the general concept of assertion checking . Usually assertions (as they're called) are used only in "testing" or "debug" builds and stripped out of production

How can one check if a variable is an instance method or not? I'm using python 2.5. Something like this: class Test: def method(self): pass assert is_instance_method(Test().method) Tom Dunham inspect.ismethod is what you want to find out if you definitely have a method, rather than just something you can call. import inspect def foo(): pass class Test(object): def method(self): pass print inspect.ismethod(foo) # False print inspect.ismethod(Test) # False print inspect.ismethod(Test.method) # True print inspect.ismethod(Test().method) # True print callable(foo) # True print callable(Test) #

Nunit安装 首先说下，nunit2.X与3.X版本需要安装不同的vs扩展。 nunit2.x安装 安装如上3个，辅助创建nunit测试项目与在vs中运行单元测试用例 . 1.Nunit2 Test Adapter 帮助在vs中能够运行调试测试用例。 2.Test Generator Nunit extension 帮助生成用例。 3.Nunit Vs Templates 帮助创建Nunit项目和用例模板。 安装完之后，就可以做基本的测试啦。如果想用如下的Client辅助测试 。 https://github.com/nunit/nunitv2/releases/tag/2.6.4 目前只支持的版本为2.6.4最高，使用客户端的话，不支持Nunit3.X版本。 使用客户端界面调试 添加外部工具 工具->外部工具 nunit3.x安装 3.x与client不兼容。安装如下3个，在vs中运行即可。 Nunit属性 TestFixture 它标记一个类包含测试，申明该类是用来测试的。一般用在class的定义之前； Test 一般是放在method之前，表示对该方法的测试，中添加Description参数可以给我们测试的功能添加描述信息 TestCase(arguments) 属性标记有参数无返值方法为测试方法(泛型方法一样标记),想要多次测试可用逗号隔开([TestCase(1,2),
