Seven principles that should be known by software testers

2022-06-11 02:10:00 【Xiaowu knock code】

The principle of software testing is to help the test team effectively use their time and energy to discover the hidden of the test project bug Guidelines for . From practice and research, the following conclusions can be drawn 7 Basic principles of software testing , So that testers can be widely used in the field of software testing .

1、 Testing proves that the software is defective -

Testing shows presence of defects

● Testing can only prove that there are defects in the software , But it does not prove that there are no defects in the software .

● Software testing is to reduce the possibility of defects , Even if no defect is found , Nor can it prove that the software is perfect .

2、 It's impossible to run out of tests -

Exhaustive testing is impossible

● It's impossible to run out of tests . Such as addition of calculator - Functional testing .

● Now the scale of software is getting larger and larger , More and more complicated , It's impossible to test completeness . In the test phase , Testers can conduct centralized testing according to risks and priorities , So as to ensure the quality of the software . Insert picture description here
3、 Test early intervention -Testing early

● Why should the test intervene as soon as possible , Simply put, it is to ensure software quality , Reduce risk and cost .

● Testers usually get involved in the requirements phase , Enable defects to be found in the requirements or design stage , The earlier the defect is found , The smaller the cost of repair . Insert picture description here
4、 Defect clustering （2/8 principle ）-

Defect clustering

● This is also a matter of experience , It is generally believed , Per cent 80 Of the defects are concentrated in 20 The core functional area of . Once you find a defect in a functional module , Most of the relevant nearby functions will also have problems .

● In the actual combat of the project , When writing defect report , Make a horizontal comparison , Compare similar functions , Similar modules , edition , Model . When specifying regression testing strategies , You can also focus on testing .

5、 pesticide paradox （ Insecticide effect ）-

Pesticide Paradox

● Repeated use of the same insecticide will cause pests to become immune to the insecticide and cannot kill the pests . The same goes for software testing . If you always use the same test method or means , You may not find new bug.

● To solve this problem , Test cases should be reviewed and revised regularly , Add new or different test cases to help find more defects . Testers cannot always rely on existing testing techniques , We should constantly improve the test methods to improve the test efficiency . Insert picture description here
6、 Test activity depends on test content -

Testing is context dependent

● Depending on the business , Software testing is also divided into different industries , Like the game industry 、 Electricity industry 、 Financial industry . Different industries , Testing activities are carried out differently , Such as testing technology 、 Selection of test tools , The testing process is different , Therefore, the development of software testing activities depends on the tested content .

● such as ： You test at a financial company , Security comes first . E-commerce testing , Functionality is more important .

7、 The fallacy that there is no defect -

Absence of error

● Software testing is not just about finding out Bug Activities that exist , Instead, we need to confirm whether the software meets the expectations and needs of users , If the product can not meet the needs of users , Even if there are no defects , This product also failed .

●“ There is no mistake ” It is not our pursuit , In the age of the Internet , It is our tireless pursuit to create maximum value for users all the time .
