Python单元测试框架unittest简明使用实例
测试步骤
1. 导入unittest模块
import unittest
2. 编写测试的类继承unittest.TestCase
class Tester(unittest.TestCase)
3. 编写测试的方法必须以test开头
def test_add(self)
def test_sub(self)
4.使用TestCase class提供的方法测试功能点
5.调用unittest.main()方法运行所有以test开头的方法
if __name__ == '__main__':
unittest.main()
实例如下
被测试类
#!/usr/bin/python
#coding=utf-8
class Computer(object):
@staticmethod
def add(a, b):
return a + b;
@staticmethod
def sub(a, b):
return a - b;
测试类
#!/usr/bin/python
#coding=utf-8
import unittest
from Testee import Computer
class Tester(unittest.TestCase):
def test_add(self):
self.assertEqual(Computer.add(2, 3), 5, "test add function")
def test_sub(self):
self.assertEqual(Computer.sub(5, 1), 4, "test sub function")
if __name__ == '__main__':
unittest.main()
运行结果:

Python is widely used in the fields of web development, data science, machine learning, automation and scripting. 1) In web development, Django and Flask frameworks simplify the development process. 2) In the fields of data science and machine learning, NumPy, Pandas, Scikit-learn and TensorFlow libraries provide strong support. 3) In terms of automation and scripting, Python is suitable for tasks such as automated testing and system management.

You can learn basic programming concepts and skills of Python within 2 hours. 1. Learn variables and data types, 2. Master control flow (conditional statements and loops), 3. Understand the definition and use of functions, 4. Quickly get started with Python programming through simple examples and code snippets.

It is impossible to view MongoDB password directly through Navicat because it is stored as hash values. How to retrieve lost passwords: 1. Reset passwords; 2. Check configuration files (may contain hash values); 3. Check codes (may hardcode passwords).

As a data professional, you need to process large amounts of data from various sources. This can pose challenges to data management and analysis. Fortunately, two AWS services can help: AWS Glue and Amazon Athena.

The steps to start a Redis server include: Install Redis according to the operating system. Start the Redis service via redis-server (Linux/macOS) or redis-server.exe (Windows). Use the redis-cli ping (Linux/macOS) or redis-cli.exe ping (Windows) command to check the service status. Use a Redis client, such as redis-cli, Python, or Node.js, to access the server.

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

Question: How to view the Redis server version? Use the command line tool redis-cli --version to view the version of the connected server. Use the INFO server command to view the server's internal version and need to parse and return information. In a cluster environment, check the version consistency of each node and can be automatically checked using scripts. Use scripts to automate viewing versions, such as connecting with Python scripts and printing version information.

Navicat's password security relies on the combination of symmetric encryption, password strength and security measures. Specific measures include: using SSL connections (provided that the database server supports and correctly configures the certificate), regularly updating Navicat, using more secure methods (such as SSH tunnels), restricting access rights, and most importantly, never record passwords.
