Overview

This product allows developers to create TTW Selenium test suites inside their Zope instance, in order to do browser-based functional testing of their site.

Installing the Product

1. Unpack the tarball in a temporary location.
2. Copy or move the Zelenium directory to the Products directory of your INSTANCE_HOME.
3. Restart Zope.

Using Zelenium

You can add a Zuite object at any location within your Zope site. It behaves as a standard ordered folder, with a couple of differences:

• It's index_html is the "TestRunner.html" view familiar from Selenium.
• It derives the test suite (in the upper left corner iframe) from all OFS.Image.File objects whose names start with test. You can use the OrderedFolder support to modify the order in which the test case files are run.
• It provides a "Zip" action, which allows you to export the test suite, all test cases, and the supporting Selenium Javascript / CSS files as a single, self-contained zipfile.

Adding Tests

Tests are just File instances whose names begin with test. They should have a content type of text/html, and should contain a table which defines the steps which make up the test case.

See http://selenium.thoughtworks.com/testrunner.html for documentation on the table structure and the Selenese language.

Using Additional Metatypes as Test Cases

On the "Properties" tab of your test suite, you can add / modify the list of meta_types which the suite will allow as test cases. Adding "Script (Python)", for instance, allows you to define test cases in PythonScripts.

Nesting Test Suites

Each test suite automatically includes the test cases of any suite it contains. You can take advantage of this feature to organize your test cases in a hierarchy, running them in separate segments, or all at once.

Including Tests from the Filesystem

Test suites now have a property, 'filesystem_path'; if set, the suite will recursively load testcases from files in / under the directory pointed to by that path.

The list of files to be included is computed via the following rules:

• If the directory contains a file, .objects, it is presumed to contain a list of files to be included, one per line; only those files / subdirectories (if present) will be included. In this case, the test cases will be presented in the order indicated in the file, followed by any test cases from subdirectories.
• Otherwise, if the suite's property, filename_glob is non-empty, it will be expanded (via Python's glob.glob) to compute the list of filenames. The test cases will be presented in alphabetical order, followed by any test cases from subdirectories.
• Otherwise, any file will be considered a testcase. The test cases will be presented in alphabetical order, followed by any test cases from subdirectories.

Exporting an Archive

On the "Zip" tab, supply a filename and click the "Download" button. The Zuite object will construct a zip file with the following contents:

index.html

the "TestRunner.html" framework page

TestSuite.html

the list of test case files (rendered as static HTML)

'test*"

your test case files (appending .html if the IDs do not have extensions)

Each of the supporting .js and .css files which drive the browserbot.

Creating a Snapshot

On the "Zip" tab, supply a filename and click the "Download" button. The Zuite object will construct a zip file with the same contents described above, and then save it as a File object in its own contents.

Generating Testcases using tcpwatch

1. Download the tcpwatch product from Shane Hathaway's site:

http://hathawaymix.org/Software/TCPWatch

1. Unpack and run tcpwatch in its "HTTP proxy" mode, with recoring turned on. E.g., the following command runs the proxy on port 9999, recording the request / response data to the directory '/tmp/recorded_scenario':

           $ python /path/to/tcpwatch/ tcpwatch.py \
               -p 9999 -r /tmp/recorded_scenario 
   

2. Configure your browser to use an HTTP proxy on localhost, port 9999.
3. Click through your site, exercising the features you are testing.
4. Stop the proxy. Run the generator.py script, pointing to the directory where tcpwatch was recording:

           $ python /path/to/Zelenium/generator.py \
              --logfile-directory=/tmp/recorded_scenario \
              --output-file=test_case_name.html
   

5. Edit the generated test case, removing / correcting the various steps.
6. Upload the test case to a Zelenium Zuite and run it.

Capturing Results from the Test Run

Selenium has a feature which allows the testrunner to upload result data from an automated test run to the server.

Invoke the test suite from your browser as usual, but append the query string ?auto=1, to the URL, e.g.::

http://localhost:8080/test_suite?auto=1

Selenium will run all test cases, and then upload its result data to the postResults method of your suite. (Note that you no longer need the postResults PythonScript in the root of your site, because the latest version of Selenium posts to that name relative to the test suite).
