3 years of testing experience. I don't even understand what I really need on my resume. I need 20K to open my mouth?

2022-06-25 02:15:00 【Xiaowu knock code】

I recently read about 15 resumes , They are all applying for the position of test engineer in my team . But none of them made it clear how he conducted the test .

Below I excerpt some Information ：

Almost all the candidates listed a list of familiar “ technology ”（ Including but not limited to ….Net, Unix, SQL, XML, MS Office）

Then they listed a lot of testing tools that looked a little outdated （ Including but not limited to …TestDirector, LoadRunner, QuickTest Pro, SilkTest, BugZilla）

however … I don't even know how they test it .

All resumes have lists of test terms and nouns … for example ,“ Understand white box testing 、 Grey box testing 、 Black box testing 、 Pressure test 、 Performance testing 、 A functional test 、 Integration testing 、 Usability testing 、 Smoke testing 、 regression testing 、 Manual testing 、 Automated testing and acceptance testing .”

Whenever I see this tone , I just wanted to “ ok , Do you know the glass box test ？ That's what we really need .”

Some candidates will even include in their resumes “ I wrote 50 Page test report ”, perhaps “ The enterprise projects I tested have more than 1000 Users ”.

ok , How on earth do you test ？ For the sake of fairness , It is difficult to answer this question with only a few resumes , On the other hand , Maybe I lack the ability to mine information between these lines , So it's really hard for me to judge who should be chosen for the interview . however , If his resume contains the following , That will probably win my favor ：

The testing process of the project I participated in is as follows …

Visit my testing blog to learn more about my understanding of testing …

My favorite test books and blogs are as follows …

I like testing because …

alas , I think a modern resume may not be very useful for identifying candidates . That explains why interview questions are so important . I have prepared a series of good questions for tomorrow's interview to judge whether they are good The tester of . One of them is ：“ If you want to test the light switch on the back wall completely , How are you going to do ？”

All these problems add up , Or the basic grasp is not reliable , The knowledge framework is flawed , Closure not completed , Lack of certain project experience

I have summarized the following points through induction , You can also use it as a review reference .

In fact, the interviews of software testing posts are almost the same . These knowledge points often asked , In order of importance , I think it can be arranged like this ：

Theoretical basis
Linux Basics
MySQL Base to
Web test
The interface test
App test
Performance testing

Now I have sorted out a study note in this order of importance

Test theory ：

The goal of software testing

Find as many mistakes as possible , Testing is the process of running a program to find errors .

A good test case is a use case that is likely to find errors that have not been found so far .

A successful test is a test that reveals errors that have not been discovered so far .

How many categories does software have ？

Depending on the function , Computer software can be roughly divided into four levels ：

The closest thing to computer hardware is some small software . They implement some of the most basic functions , Usually “ curing ” In a read only memory chip , Therefore, it is called firmware .
System software includes operating system and compiler software . The system software and hardware together provide a “ platform ”. They manage and optimize the use of computer hardware resources .
Support software . Including graphical user interface 、 Software development tools 、 Software evaluation tool 、 Database management system 、 Middleware etc. .
There are many kinds of application software , Including office software 、 E-commerce software 、 communication software 、 Industry software , Game software, etc .

Linux Basics

stay Linux In the system , Access to a file is 755

755 Indicates that the owner of the file has read access to the file 、 Write 、 Executive authority , Users in the group of the file owner and other users have read and execute permissions on the file .

How to view the end of a file 50 That's ok ？

see /etc/profile Before 10 Row content , Should be ： # head -n 10 /etc/profile

see /etc/profile Last 50 Row content , Should be ： # tail -n 50 /etc/profile

MySQL Basics

What is a database ？

database (Database) It's organized according to the data structure 、 Warehouse for storing and managing data

What is a relational database , Primary key , Foreign keys , What are the indexes ？

Relational database is a database composed of many two-dimensional row and column tables that can be connected with each other

Key words (primary key) Is one or more fields in a table , Its value is used to uniquely identify a record in the table

A foreign key represents a correlation between two relationships . A table whose primary key is a foreign key of another relationship is called the primary table , With this foreign key

The table of is called the slave table of the master table . Foreign key is also called foreign key

In a relational database , The index is a separate 、 A storage structure that physically sorts the values of one or more columns in a database table ,

It is a collection of one or more column values in a table and a corresponding list of logical pointers to the data pages in the table that physically identify these values

Web test

nginx,tomcat,apache What are they ？

Nginx (engine x) Is a high-performance HTTP And reverse proxy , Also a IMAP/POP3/SMTP The server .

Apache HTTP Server Is a modular server , From the NCSAhttpd The server

Tomcat The server is a free open source Web application server , Application servers are lightweight , Is development and debugging JSP Program preference .

The interface test

What is an interface

Interface refers to the interaction point between external systems and internal subsystems .

Including external interfaces 、 Internal interface , The internal interface also includes ： Interface between upper layer service and lower layer service 、 Peer interface .

If the module requests http Change it to https , How the test plan should be developed , modify ？

Use them separately http also https Log in and try . If you use https Can log in normally , The address bar shows a lock , So this website is deployed SSL Of . If http and https Can log in normally , It further explains that the website does not have mandatory https Sign in , Or no settings http Link auto jump https link ; On the contrary, if you use http Sign in , Results jump to https page , It shows that the website has deployed SSL, And set up http Automatic jump https.

App test

What is? Android Four components ？

Android The four components of the include ：Activity、Service、BroadcasReceiver、ContentProvider

Face the

Many questions have been forgotten , The most impressive questions are the following ：

According to your work experience , Tell me about your understanding of quality assurance ？
The difference between non relational database and relational database , Talk about their advantages ？
What mature solutions are there in Automation , Have you ever done secondary development ？
If the quality department needs to customize a quality system platform , What questions would you consider ？
I have sorted out the answers for you ：

1. According to your work experience , Tell me about your understanding of quality assurance ？

This is a comprehensive basic knowledge problem , Test your experience after working in the testing industry for several years , Whether there is a test thinking , Make your position clear . You can talk about how you think to do well in testing ？ How to measure quality ？ How do you focus on software quality improvement , Help the team iterate quickly and deliver high quality

2. The difference between non relational database and relational database , Talk about their advantages ？

I don't need to repeat the importance of database in testing , You need to understand the principles of common relational databases and non relational databases , And sum up their previous differences

3. What mature solutions are there in Automation , Have you ever done secondary development ？

Test engineers cannot do without a keyword ,“ automation ”, Automated testing technology is more or less used in any type of project . About front and rear end automation technology , Is there a complete test framework , Technical system . In the understanding of open source automated testing framework , Have certain development thinking , Can be encapsulated , Secondary development on open source framework . Be able to flexibly create a test framework suitable for the team according to the project , It's a watershed for test engineers

4. If the quality department needs to customize a quality system platform , What questions would you consider ？

Tell the truth , The interviewer asked the question of the test platform , You may not be able to carry it . Anyone who has done test development should know , Construction of test platform , In addition to the technical difficulties . You have to think about how to promote this work ？ After the development of the test platform , It is a big problem to promote and operate this platform in the whole testing department . From the perspective of functional testers , Use an immature test platform to test , If you increase your workload , It doesn't have much value for your own work and Technology , Generally, they are not very active to cooperate , How to promote the operation of the test platform is a difficult problem . You should let everyone feel the difference between using and not using this test platform .
