That's what software testing is all about?!

1、 What is software testing ?

Check whether the functions on the software are in accordance with the expected results , Whether the actual result is the same as the expected result .

The highest level of software testing is prevention bug.

2、 Professional development of software testing

  • A functional test
  • automated testing ( Test Development 、 Continuous integration 、testops)
  • Performance testing ( Advanced performance testing 、 Architects )
  • Switch ( Development 、 product 、 Operations etc. )

3、 Classification of software testing

1、 According to the method :

  • Black box testing ( Check whether the input and output are correct , There's no need to understand the principle )
  • White box testing ( Understand the internal structure , Look at the code, right )
  • Grey box testing ( Black box and white box )

2、 In the direction of :

  • A functional test
  • Performance testing ( Pressure test —— Find software performance bottlenecks 、 The load test 、 Concurrent test —— Many people do the same thing at the same time , For example, will the second kill 2 People grab at the same time )
  • Security testing —— hackers

3、 By stage :

  • unit testing —— Method 、 function 、 class
  • Integration testing —— Interface
  • The system test —— function 、 Security 、 performance 、 Compatibility (web、app)、 Ease of use ( User experience )、 stability (7*24 Whether the hours are stable )、UI( Interface )
  • The acceptance test

4、 By object :

  • APP test
  • WEB test
  • Internet of things testing
  • Internet of vehicles test
  • Applet testing
  • Embedded testing
  • Big data test
  • AI test

5、 By status :

  • The static test ( White box look at the code )
  • Dynamic testing ( Black box or grey box )

6、 other : Smoke testing ( The test before the test )、 regression testing ( Check bug Has it been modified )、α test ( Internal measurement )、β test ( Public survey )

4、 R & D management model

1、 The waterfall flow :

3、W Font type :

4、 Agile model : Efficient work 、 Timely communication 、 daily 、 Whiteboard 、 Morning meeting / Standing will 、 Centralized office

5、 Testing process

1、 Demand analysis stage :

  • Demand analysis —— The requirements document 、 prototype 、 Dictation ;
  • Learning business processes ;
  • Extract function points ;
  • Write requirement analysis specification ; What to do without demand —— Refer to the implementation of the same type of products that have been mature on the market

2、 Test design stage :

  • test plan ——5W1H, The emphasis is on the arrangement and allocation of time and personnel and resources
  • Test plan : The focus is on how to test for each test content 、 What test plan to use 、 What testing tools
  • The test strategy : Which test items should be tested first 、 What content is tested after 、 What are the criteria for starting and ending testing
  • The test case : Use case number ( Unique )、 Use case name ( simply , Use the minimum number of words to describe what this use case does )、 precondition ( Before executing this use case , The software must meet the requirements )、 priority ( The time to execute this use case requires urgent registration )、 Importance level ( The importance level of the function under test in the system )、 Test data 、 testing procedure 、 Expected results 、 The actual result

3、 Test execution phase

  • Compare the expected result with the actual result , If it's the same, go through , If not, there are problems
  • Submit bug
  • regression testing : In version 2 Check on the version 1 Have the problems found on have been solved

4、 Test summary stage
Write test report :

  • A summary of the work
  • Yes BUG Statistical analysis of : test 、 Development 、 Software modules 、 Grade 、 The time to fix it 、 Each version 、 state
  • Evaluation of the quality of the software under test : First and second class BUG It's all closed , Level three BUG Shut down the 80%, Level Four BUG It doesn't matter

6、 The test method

  • Equivalence class : Represent the majority by a few parts
    Invalid equivalence class 、 Effective equivalence class

  • The boundary value

  • Scene method

  • Cause and effect diagram

  • Decision table

  • Path coverage

7、 review

  • Peer review
  • Group review
  • Department review
  • Project review
  • Third party review
  • Mail review

8、BUG Management of

  • BUG Management platform / System / Tools
    ZenTao 、BUGFree、ALM/QC、JIRA

  • BUG The six elements of
    1、 Number

    2、BUG The name of ( simply , When you see the title, you know what the problem is )

    3、BUG The priority of the ( According to the actual situation , This BUG Need priority , High school low )

    4、BUG Level of ( Deadly —— Affect the normal use of the core process of the product , Cause the software to hang up 、 Flash back 、 Collapse , It's about money ; serious —— The function cannot be used normally ; General —— There's something wrong with some of the features ; Slight —— Something suggestive , Such as user experience ,UI On the problem )

    5、BUG The steps to reproduce
    You can copy the steps of the use case 、 Expected results 、 The actual result

    6、 The attachment
    Screenshot / journal / video ( The purpose is to BUG evidence )

  • BUG Life cycle of
     Insert picture description here

  • BUG The state of
    newly build 、 open 、 Confirmed 、 resolved 、 Refuse 、 Reopen 、 close 、 Postpone processing 、 repeat BUG

  • BUG Level of

9、 The test application

1、APP test

  • install / uninstall
  • Message push
  • to update
  • Weak network test (2G/3G/4G/5G/WIFI)
  • Scenario interaction testing ( There's a call 、 Listening to music 、 Call camera 、 Switching between the front and back stations )
  • Authority test
  • Offline testing

2、WEB test

10、 Software architecture

1、B/S
browser browser
server The server

2、C/S
client client ( Separate installation required , such as APP)
server The server

11、 Version of the iteration

  1. Over time / The promotion of the number of tests , There will be many releases , The version number is constantly superimposed
  2. Incremental testing : Only test the functions that are known to change
  3. Full test : Test all functions of the software
