这次给大家带来unittest+coverage怎么进行单元测试覆盖,unittest+coverage进行单元测试覆盖的注意事项有哪些,下面就是实战案例,一起来看一下。
基于上一篇文章,这篇文章是关于使用coverage来实现代码覆盖的操作实例,源代码在上一篇已经给出相应链接。
本篇文章字用来实现代码覆盖的源代码,整个项目的测试框架如下:
就是在源代码的基础上加了一个CodeCover.py文件,执行该文件会在目录CoverageReport生成相应的覆盖报告。如下是CodeCover.py的源码:
#coding=utf8 import os import time def findTestWithPath(): current_dir=os.getcwd() folderName=os.listdir(current_dir) #print folderName #获取到测试文件所在目录 TestSuit=[suite for suite in folderName if not suite.find("TestSuit")] #用来保存测试文件 testfile=[] withPathFile=[] for suite in TestSuit: #获取测试目录下的所有测试文件 testfile=testfile+os.listdir(".\\"+suite) for withPath in testfile: withPath=current_dir+"\\"+suite+"\\"+withPath withPathFile.append(withPath) del testfile #把testfile中的py文件挑选出来 withPathFile=[name for name in withPathFile if not "pyc" in name] #print testfile print withPathFile return withPathFile def codeCoverage(): now = time.strftime("%Y%m%d%H%M") htmlReport=os.getcwd()+"\\"+"CoverageReport" htmlCmd="coverage html -d " + htmlReport +"\\"+now for pyfile in findTestWithPath(): runPyCmd="coverage run " + pyfile if os.path.exists(htmlReport) : os.system(runPyCmd) os.system(htmlCmd) else: os.mkdir(htmlReport) os.system(runPyCmd) os.system(htmlCmd) if name=="main": codeCoverage()

The above is the detailed content of How unittest+coverage performs unit test coverage. For more information, please follow other related articles on the PHP Chinese website!

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
