Software testing is a post that has only begun to rise in recent years , I write some common questions here , I hope I can help you .

Friends who like software testing are welcome to communicate with me in private letters .

1、 Test thinking I understand

QA Value is reflected in the ability to catch anomalies that others cannot catch

for instance , Vote on company resolutions

1、 The pass rate is not reached , Then voting continues
2、 The opposition ratio reached ( 1 - P ) Then the voting ends
3、 The general manager exercised a veto

In this function , The anomaly lies in , Determine whether voting has ended , It is determined by looking for fields in the database

When you make a request , The database will not be verified

Thus, there are the following particularly tricky scenes

It's one vote away from passing the resolution
here , The employee and the general manager opened the voting interface at the same time

Then the general manager will first implement a veto , The vote is over

But the employee interface has not been refreshed ,【 Support 】 The button is still on the interface

Then the employee clicks 【 Support 】, It covers the result of one vote veto by the general manager

As for the consequences , Salary deduction is still a small matter , If heavy losses are caused by the resolution , More trouble

Here's another example , Baidu online disk uploads files to the cloud , Design test cases according to this function

（1） Account type
Account cancelled ; Normal use account ; Baidu online disk member users
（2） The choice of uploading files
Type of uploaded file 、 Number

Check ABC, The uploaded file is ABC

target file type （ Public folder / Private folder ）
The file has been occupied by other processes in the operating system
（3） The size of the remaining space

There's plenty of room left 、 Insufficient

Insufficient situation , Batch upload , Enough to pass two , But not all
（4） Upload process
Pause many times to continue ; Network interruption ; During the uploading process, the online disk membership expires ;
In the process of uploading ： Add transfer file
In the transmission list , Clear those that have not been uploaded 、 Uploaded 、 Uploading
In the operating system , Delete the files that have not started uploading 、 Uploading file （ Capture exception ）
（5） Upload results
Prompt upload successful , Is really successful , Prompt failure, really fail

2、 My understanding of work

（1） Why software testing is needed ,QA What value can be created

QA The value created , As written in the part of testing thinking

Find some tricky user scenarios to test , Discover software defects

So as to improve the software quality

（2） The importance of interface testing , Not lower than interface testing , It is inconclusive who is important

The importance of interface testing is no longer described , Let's imagine , Button not available , Or display dislocation and so on

Interface testing is about system security , The most serious problem is that the interface exceeds its authority , Get the data that the current user does not have permission to access

3、 Engaged in software testing , What kind of abilities are needed ？ How to go further ？

The most direct , We should agree QA The value of , from QA Value finds a sense of professional achievement

Because testing itself is also a boring job , Only oneself agree , To go further

Then it is also more core , Is to test thinking

A lot of people are new to the business , That is to say, we should engage in Automation 、 Do test development 、 Engage in penetration testing

first-class QA It doesn't mean mastering how advanced the testing framework is , Instead, you can find unexpected test corners of others

because Automation is only an auxiliary means of testing , It's a bonus , More important than bonus items , It is the thinking of solving problems

Besides , We should also constantly learn new technologies

（1） Testing tools

（2） The test framework （ Use automation to do things that are done repeatedly by hand ）

（3） Test technique （ Use interface 、SQL Quickly create test data ）

（4） Basic skills of computer （ For example, computer network 、Linux、 Microservice load balancing 、 Branch management ）
（5） Basic skills of the test （ Write use cases ）

We should also continue to accumulate experience

（1） Test thinking , Constantly accumulate some tricky bug, Good questions from others , Broaden your mind

（2） Ability to analyze influence surface , After the test , Quickly judge the influence surface , Improve test efficiency

（3） Evaluate the impact of version launch

There are also some general abilities in the workplace

（1） communication skills , Presentation skills , Ability to follow up problem solving

（2）100% Sense of responsibility , For every new feature , Every line of code is skeptical

4、 What are some problems that are easy to encounter in the process of work ？

（1） I don't think so bug, It's hard to fix

This is a very common problem , How to deal with the problem , I think there are many solutions

（1） Ask the product manager for confirmation , Let the product manager decide

（2） If there is no product manager , Manually evaluate bug Influence degree

（ Number of groups , Frequency of use , severity , Repair bug The human cost of ）

If none of the functions are used , Then no matter how perfect it is

If it is used frequently , Small optimization will also bring huge benefits

In addition, there is no need to make contradictions with development because of some problems , The relationship between colleagues is also very important

（2） Quality is difficult to control , Anxious to go online , Short test time

Only enough time can be left to test , If the time is too short , Have the right to refuse to put the test online

（3） It is difficult to communicate with developers , For the way to solve the problem , Easy to disagree

Same as the first point , Let the product manager decide , There's no need to waste time if you can't communicate

（4） How to deal with occasional bug problem

A lot of times ,QA The staff raised some occasional questions , The developer will not accept

This is a good question , Welcome to leave comments and discuss

（5） The test environment is difficult to test , It needs to be verified in the production environment

I'll add this later , I have something to do first

5、 Career planning of testers

This is also added later , Get busy first

In addition, you are welcome to discuss the software testing industry with me
