全功能Python测试框架:pytest   python通用测试框架大多数人用的是unittest+HTMLTestRunner,这段时间看到了pytest文档,发现这个框架和丰富的plugins很好用,所以来学习下pytest. image.png pytest是一个非常成熟的全功能的Python测试框架,主要有以下几个特点: 简单灵活,容易上手 支持参数化 能够支持简单的单元测试和复杂的功能测试,还可以用来做selenium/appnium等自动化测试、接口自动化测试(pytest+requests) pytest具有很多第三方插件,并且可以自定义扩展,比较好用的如pytest-selenium(集成selenium)、pytest-html(完美html测试报告生成)、pytest-rerunfailures(失败case重复执行)、pytest-xdist(多CPU分发)等 测试用例的skip和xfail处理 可以很好的和jenkins集成 report框架----allure 也支持了pytest 安装pytest: pip install -U pytest 验证安装的版本: pytest --version 几个pytest documentation中的例子: 例子1: import pytest # content of test_sample.py def

How to handle AssertionError in Python and find out which line or statement it occurred on?

拈花ヽ惹草 提交于 2019-11-29 20:14:48
I want to handle AssertionError s both to hide unnecessary parts of the stack trace from the user and to print a message as to why the error occurred and what the user should do about it. Is there any way to find out on which line or statement the assert failed within the except block? try: assert True assert 7 == 7 assert 1 == 2 # many more statements like this except AssertionError: print 'Houston, we have a problem.' print print 'An error occurred on line ???? in statement ???' exit(1) I don't want to have to add this to every assert statement: assert 7 == 7, "7 == 7" because it repeats

Is using assert() in C++ bad practice?

橙三吉。 提交于 2019-11-29 20:13:57
I tend to add lots of assertions to my C++ code to make debugging easier without affecting the performance of release builds. Now, assert is a pure C macro designed without C++ mechanisms in mind. C++ on the other hand defines std::logic_error , which is meant to be thrown in cases where there is an error in the program's logic (hence the name). Throwing an instance might just be the perfect, more C++ish alternative to assert . The problem is that assert and abort both terminate the program immediately without calling destructors, therefore skipping the cleanup, whereas throwing an exception

C# - What does the Assert() method do? Is it still useful?

I am debugging with breakpoints and I realize the assert call? I thought it was only for unit tests. What does it do more than breakpoint? Since I can breakpoint, why should I use Assert? Patrick Desjardins In a debug compilation, Assert takes in a Boolean condition as a parameter, and shows the error dialog if the condition is false. The program proceeds without any interruption if the condition is true. If you compile in Release, all Debug.Assert 's are automatically left out. juan From Code Complete 8 Defensive Programming 8.2 Assertions An assertion is code that’s used during development

Assert statement in Verilog

风流意气都作罢 提交于 2019-11-29 18:00:45
问题 I'm completely new to Verilog, so bear with me. I'm wondering if there is an assert statement in Verilog. In my testbench, I want to be able to assert that the outputs of modules are equal to certain values. For example, mymodule m(in, out); assert(out == 1'b1); Googling gave me a few links, but they were either too complex or didn't seem to be what I wanted. 回答1: There is an open source library for assertions called OVL. However, it's pretty heavy. One trick I nicked from there is creating a

0x01 代码执行 1.1 概念 远程代码执行实际上是调用服务器网站代码进行执行。 1.2 常见执行方法 eval eval():将字符串当做函数进行执行(需要传入一个完整的语句) demo: <?php eval('echo "hello";'); ?> assert assert():判断是否为字符串,是则当成代码执行 demo: 低版本: <?php assert($_POST['a']);?> php官方在php7中更改了assert函数。在php7.0.29之后的版本不支持动态调用。 7.0之后的demo: <?php $a = 'assert'; $a(phpinfo()); ?> call_user_func call_user_func():回调函数,可以使用is_callable查看是否可以进行调用 demo: <?php highlight_file(__FILE__); $a = 'system'; $b = 'pwd'; call_user_func($a,$b); call_user_func('eval','phpinfo()'); ?> 其中基本可以传递任何内置的和用户自定义的函数, 除了语言结构:array、echo、empty、eval... call_user_fuc_array call_user_fuc_array():回调函数,参数为数组

do{...} while(0)

前段时间看公司项目源码时,发现一个很有意思的地方,就是在很多宏函数定义里会出现do{...} while(0)。 #define ASSERT_ARRAY_EQ(expect, actual) do { / ASSERT_EQ(sizeof(expect), sizeof(actual)); / for( size_t i = 0; i < sizeof(expect)/sizeof(int); i++) / { / ASSERT_EQ(expect[i], actual[i]); / } / } while(0) 开始的时候百思不得其解,写不写这个循环似乎都只会跑一次,那是不是多此一举呢。后来仔细想了想,这么做在实际的工程项目中的确是非常有用的。 如果不使用do{...} while(0),在非嵌套使用的情况下,使用这个宏是不会出现什么问题的。 /* ...........code............ */ ASSERT_ARRAY_EQ(expected, actual); /* ...........code............ */ 上面这段代码里中间那一行会被宏函数直接替换。 然而,考虑下面这种情况: if(...) ASSERT_ARRAY_EQ(expected, actual); else ... 如果没有do{...} while(0)

Is Groovy's assert a good idea for production code, unlike Java's assert?

旧街凉风 提交于 2019-11-29 11:13:32
问题 In Java it's known that using the assert keyword is usually a bad idea, as its behavior is dependant on the runtime enviornment (it doesn't do anything by default, unless the -enableassertion is passed to the java runtime). Is Groovy's assert different? Is it always executed in production code, and is it recommended to use in production code? (In Java you would use something like Preconditions instead) From my sanity tests it seems that by default assert works well without any flags, and that
