Fundamentals of software testing

1. Coding habits

Code file naming ： Don't use numbers . Symbol . It starts in Chinese , Symbol except （_）, Try to use English names

id.name.class Property value ： Try not to use Chinese and pure numbers

When creating a folder ： Remember to use 1.2.3

1. When deleting software, you must uninstall it through the control panel , Then delete the remaining files

2. If you want to change the directory when installing the software , Usually uninstall first , reinstall （ Be careful not to cut ）

3. Descendant selector

Concept ： First locate the ancestor element , Limit the search scope , Then go to find the target element

expression ： Selection expression of ancestor element The selection expression of the target element

Example ：

4. Child Selector

      Concept ： First locate the parent element , Limit the search scope , Then go to find the specific target sub element

      expression ： Selection expression of ancestor element > Selector expression of the target element

5. Summary

 5.js Writing position

Inline

  embedded

  Outer chain

 7.js Modify page elements

 8. Software architecture

cs framework ： client - The server

      cs Architecture software , For different software environments, corresponding versions need to be developed independently

        For this feature , Software testers need to know cs Software implementation and installation of architecture / Uninstall test ;

       Cs Architecture software has high requirements for developers and development costs , Inconvenient to maintain ;

BS framework ： browser - The server

        BS Architecture software , Just consider the compatibility on different browsers ;

        BS Architecture software cannot formulate personalized functions ;

     ( back ) difference ：

      efficiency ：c/s Efficient , Some content is already installed in the system ,b/s Load the latest data every time

      upgrade ：b/s Seamless upgrade ;c/s Delete the old version and install the new version

    Security ：c/s More secure , Need to install , register . Sign in ;b/s You can use it with a browser , Low level of safety

    Development costs ：b/s The cost is low ;c/s Different systems need different developers , The high cost

9. The server

The server is to provide customers with all components of the product server ;

Hardware server ： Hardware server ： The hardware server is a high configuration . Expensive price . A good computer ;

Software server ： Product based . Software provides function processing software program ;

database server ：mysql.Oracle.Sql Server

web The server ：Nginx. Apache

application server ：Tomcat. WebLogic.jboss

Who will use these software

Based on software test deployment , At that time, you need to learn the software server deployment used by the company's system deployment environment in time in your work ;

Deployment environment , General development and writing will deploy documents in detail ;
