例如,正则表达式 test 将会精确地匹配到 test。(你可以启用不区分大小写模式,让这个正则也匹配 Test 或TEST ,稍后会详细介绍。) 但该规则有例外。有些字符是特殊的 元字符(metacharacters),并不匹配自身。它们表示匹配一些非常规的内容,或者通过重复它们或改变它们的含义来影响正则的其他部分。 元字符包括:. ^ $ * + ? {
Likewise, keeping your unit-tests efficient and performant means keeping as much “slow code” out of the automated test runs, namely filesystem andnetwork access. For our first example, we’ll refactor a standard Python test case from original form to one usingmock. We’ll demonstrate how wr...

就已selenium ide录制百度搜索,来引入单元测试,打开百度,在搜索输入框中输入框webdriver,点击百度一下安装,见录制的截图: 点击selenium ide的文件下拉框,点击Export Test Case As,点击Python 2/unittest/webdriver,见截图: 保存文件为demo.py文件,打开demo.py文件,可以看到如下的代码: # -*- coding: utf-8 -*- ...
如果你已经把my_abs()的函数定义保存为abstest.py文件了,那么,可以在该文件的当前目录下启动Python 解释器,用from abstest import my_abs来导入my_abs()函数,注意abstest是文件名(不含.py扩展名)。 定义一个什么事也不做的空函数,可以用pass语句: def nop(): pass pass语句什么都不做,实际上它可以用作为...

Let's see a simple example of how to write a Locust load test: ImportHttpUser,task,timeandclasses. Createclass = AuthenticateUserthat takes an argument of theHttpUserclass. Create a variable calledtimerthat adds 10 seconds between every executed task. ...
for_stmt: 'for' exprlist 'in' testlist ':' suite ['else' ':' suite] Where exprlist is the assignment target. This means that the equivalent of {exprlist} = {next_value} is executed for each item in the iterable. An interesting example that illustrates this: for i in range(4):...
Interpreted language. Python is an interpreted language, which means the code is executed line by line. This can make debugging easier because you can test small pieces of code without having to compile the whole program. Open source and free. It’s also an open-source language, which means...
