If you want to change your career to take the test, I advise you to understand these contents first

Today, I'd like to introduce some basic attempts in the software industry , I hope it can help you have a general understanding .

Software testing needs to consider the possible problems of software from many aspects ：

Requirements testing ：

For example, we want to develop an e-commerce platform , Need another shopping cart , Product list , Customer service chat

Payment and other functions , We will put these requirements into a document .  This document is called the requirements document

A verification of our requirements document / The process of verification is called ： Requirements testing

A functional test ：

The functions we need , Make a verification , Whether the function can be used normally .

Safety test ：

Bank , negotiable securities , Government agencies . Whether the software is safe or not , Can you prevent others from invading , And modify the data

An elevator , I asked him to start from 1-15 Building use 2 Minutes can only complete , And smooth , smooth .

Reliability test ：

Can meet my requirements

Usability testing ：

I'm only responsible for getting you from 1 From the first floor to 15 floor , But I don't promise to 2 Within minutes , There's no guarantee

Smooth and smooth , It's possible to wobble .
