3.8-3.12 Review of learning situation

In the first week, I learned the main framework of testing skills, the basic structure of Internet companies, the difference between human senses and machine language when visiting websites, and simple HTML web page production

1. The main framework of testing skills

Contains four parts: test process, test case, software defect bug, and quality model:

1. Testing process The function of the testing process is to know the process of software development and how testers can participate and cooperate with other functions that can only be completed; the testing process includes test analysis, test planning, test preparation, test execution, and test summary. It is control ability.
2. Test cases The role of test cases is to help us examine software problems more comprehensively and in detail; test cases include test case design, test case review, test case execution, and test case optimization.
3. After completing the execution of the test case, the software defect bug should be recorded to facilitate the repair and tracking; specifically, it includes four steps of defect report writing, analysis, tracking, and regression testing.
4. The quality model provides testers with an overall thinking about product quality.

2. The basic structure of Internet companies

Contains the company's basic attributes, team, and products:

1. Basic attributes of the company Company name, industry, and vision.
2. Team
   3. Product Contains product name, blueprint, version planning, MVP products, new features, optimized experience, and bug fixes.

Three, visit the website

The difference between human senses and machine language (take Baidu as an example):

1. Human senses Open the browser-enter the website URL in the browser's address bar: www.baidu.com-press the Enter key-the browser display area displays the content of the Baidu page.
2. The machine language runs a software that can access and display web pages: Firefox browser-enter the domain name: www.baidu.com-call the DNS server, resolve the domain name into the IP address of the actual Baidu server-the server returns a web page we requested Resource file: xx.html-the browser receives the page source code, and the browser (rendering) displays the page represented by the source code.
   [Remarks]: DNS server is equivalent to a logbook, which records the IP address corresponding to each domain name; query method: Windows+R——input cmd——input domain name can query IP (space+ping+www.baidu.com) — —Get Baidu IP: 14.215.177.38 — Enter the IP directly in the browser address bar to directly visit the Baidu homepage.

Four, HTML webpage production

1. HTML definition Web page language HTML is a tag-based language that can help us better transmit information through the Internet.
2. Tool HBuilder.
3. Steps Double-click to open-file-new-project-basic HTML project-create a special folder for storage (the file name should not be in Chinese)
   [Remarks: common code] to be added
