Use Python to do your own automated tests--do unit tests on Java Code (2)-Import third-party jar packages

Use Jython to do unit testing of Java, of course, in order to test the development of Java code. This involves the introduction of a third package, how to import a third party package? You can use the implemented function http://blog.csdn.net/powerccna/article/details/37739207 here to scan the jar package under the specified folder, and then pass the Sys.path.append () The function is added to the Sys.path of Jython.

For Jar_file in Scan_files ("/home/jim/java_jar", postfix= ". Jar"):    sys.path.append (Jar_file)

Import third party package, must first append come in after the talent enough import, otherwise will be reported not to find the package. Some people say in the use of the same time to add to the classpath inside. When I use it. Just MySQL driver this jar package needs to be added to the classpath inside, the other directly added to the sys.path inside can be used.

Here is a demo sample third party package is commons-net-3.3, can always download the jar package here, http://commons.apache.org/proper/commons-net/download_net.cgi

Note here from org.apache.commons.net.ftp import ftpclient, or cpython a bit different, ftpclient here is a file, the corresponding CPython inside called a module, In CPython to initialize the FtpClient class. It should be ftp=ftpclient.ftpclient (), because Ftpclient.ftpclient is the real class. But this is ftp=ftpclient (), Jython is implemented in Java. Adhere to the rules of Java more points.

#!/usr/bin/env jython#coding=utf-8import sysimport osimport javaimport unittestimport Time#scan_files is a function implemented in another place, Here the implementation of the function is removed for everyone to see the unit test this clear for Jar_file in Scan_files ("/home/jim/java_jar", postfix= ". Jar"): Sys.path.append (Jar_ File) #print sys.pathfrom com.mysql.jdbc import driverimport java.sql.Connectionfrom java.sql Import Drivermanagerimport org.apache.commons.net.ftp.ftp;from org.apache.commons.net.ftp Import Ftpclientimport Org.apache.commons.net.ftp.FTPReplydef mysql_driver_test (): Java.lang.Class.forName (' Com.mysql.jdbc.Driver ') conn = Drivermanager.getconnection ("Jdbc:mysql://192.168.19.21:3306/mysql", "root", "root"), Class Ftpclienttest ( UnitTest.
