Jenkins -- continuous integration server

1. Continuous integration ：

1.1 Concept

Continuous integration ,Continuous integration , abbreviation CI.

Integrate ： All of our project code is hosted in SVN Server . Each project has several unit tests , And there's a so-called integration test . The so-called integration test is to run all unit tests and other tests that can be completed automatically . Only the code that has passed the integration test on the local computer can be uploaded to SVN Server , Ensure that there is no problem with the uploaded code . therefore , Integration refers to -- Integration testing .

continued ： Persistence refers to -- Long term integration testing of project code . Since it is a long-term , That must be automatic , otherwise , Manual execution is not guaranteed , And it takes manpower . Regarding this , We have a server , It will start from SVN Check out the code , And compile , Then run the integration test . The results of each integration test will be recorded . To complete this work is the following Jenkins Software . Of course , It does more than that . In our project , The cycle of executing this work is 1 God . That is to say , Server every 1 Every day will be on time SVN The latest code on the server automatically performs an integration test .

1.2 characteristic

• It's an automated, periodic integration testing process , Check out code from 、 Compiling and constructing 、 Run the test 、 Result record 、 Test statistics, etc. are all done automatically , No manual intervention required ;
• A dedicated integration server is needed to perform integration builds ;
• Need to be supported by code hosting tools ;

1.3 effect

• Ensure the quality of code submitted by team developers , Reduce the pressure of software release ;
• Any part of continuous integration is done automatically , No need for too much human intervention , It helps to reduce the number of repetitive processes to save time 、 Cost and workload ;

Through the following respectful service, the old man is comparing the functions of the above two items, which is very vivid ！ He has provided us with considerate continuous integration services ！ We don't need to worry too much about project integration. Just leave it to them ！

 

2.Jenkins

2.1Jenkins Introduce

Jenkins, Original name Hudson,2011 Changed its name to its present name , it It is an open source software tool for continuous integration . Official website ：​ ​http://jenkins-ci.org/​​.

Jenkins Be able to implement errors in monitoring integration , Provide detailed log files and reminders , It can also show the trend and stability of project construction in the form of chart .

2.2Jenkins characteristic

• Easy to install ： Just one.  java -jar jenkins.war, After downloading the file from the official website , Direct operation , No additional installation is required , There is no need to install the database ;
• Easy to configure ： Offer friendly GUI Configuration interface ;
• Change support ：Jenkins From the code warehouse （Subversion/CVS） Get and generate the code update list and output it to the compilation output information ;
• Support permanent links ： The user is through web To visit Jenkins Of , And these web The link address of the page is a permanent link address , therefore , You can use this link directly in various documents ;
• Integrate E-Mail/RSS/IM： When an integration is completed , These tools can tell you the integration results in real time （ as far as I am concerned , Building an integration takes time , With this function , You can wait for the results , Do something else ）;
• JUnit/TestNG Test report ： That is to provide detailed test report functions in the form of charts ;
• Support distributed build ：Jenkins Integration building and other work can be distributed to multiple computers ;
• File fingerprint information ：Jenkins Which integration builds will be saved and what results jars file , Which integration build uses which version of jars Documents and other construction records ;
• Support for third-party plug-ins ： bring Jenkins Become more and more powerful ;

Other integration tools

Other well-known continuous integration tools are ：CruiseControl,TeamCity,Continuum etc. .
