Use python for automated testing-unit test for Java code (2)-import a third-party jar package

Using Jython to perform unit tests on Java is of course to test the java code developed by the company. This involves importing the third package. How can I import a third-party package? You can use the functions implemented here in the http://blog.csdn.net/powerccna/article/details/37739207 to scan the jar package under the specified directory, and then add it to the sys. path of jython through the sys. path. append () function.

for jar_file in scan_files("/home/jim/java_jar",postfix=".jar"):    sys.path.append(jar_file)

Import a third-party package. You must append the package before you can import it. Otherwise, the package cannot be found. Some people say that they want to add the jar package of mysql driver to CLASSPATH at the same time. When I use it, I only need to add the jar package of mysql driver to CLASSPATH, while others are directly added to sys. path.

Note: from org.apache.commons.net. ftp import FTPClient is still a bit different from cpython. FTPClient is a file here. It corresponds to a module in Cpython and the FTPClient class needs to be initialized in Cpython. It should be ftp = FTPClient. FTPClient () Because FTPClient. FTPClient is the real class, But here ftp = FTPClient (), Jython is implemented in java, so follow the java rules.
