Once Ant is working, you'll need to obtain copies of both JUnit and HTTPUnit. JUnit is a framework to automate the running of unit tests, and HTTPUnit provides an abstraction layer for HTTP. These are both needed to compile the unit tests. Again, make sure your classpath is up to date.
The final step is to replace the server properties in the build.xml file so it will know how to talk to your server. You will need to give it a base URL, a username, and password for that user. are the "JVMARG" lines in the "JUNIT" section. ). In the near future, this will be moved out of the subdirectories and either into the toplevel build.xml file or into a configuration file.
You should now be ready to run the tests. Go to your server's
"packages" directory and type source ./paths.sh to set
up your classpath. Now type ant. Ant should find the
toplevel build.xml file, check that it can see JUnit, compile your
java files, and finally call Ant on each of the sub-directory
build.xml files to run the tests. You should be shown a report of
which tests failed and which succeeded.
Within the function, a typical unit test involves requesting a page, saving the result, checking the HTTP return code, then parsing out various strings to check for page functionality. The return code should be checked with "assertEquals", and any other checks should be performed with "assert". Use of "assert", "assertEquals", and exceptions allow JUnit to accurately report where a test fails.
If you need to create a set of tests for a module, the first step is to create a directory tree beneath the module directory. The current convention is to put all .java files in a "/java/src/com/arsdigita/acs/module name/test" directory. The module name should be the ACS module name, but with all dashes removed and with appropriate capitilization. All .java files that you create that contain test cases must have the word Test in the filename. All of the classes you create should be in the com.arsdigita.acs.module name.test package, and should import "com.dallaway.jsptest.*" and "junit.framework.*" (and optionally, if needed, com.arsdigita.acs.acsKernel.ACSCommon). Next, the public class needs to extend "TestCase", and provide new method definitions for "suite()" and the constructor. Typically, in the constructor, you should extract the system property "system.url" to determine which server to test against.
