Introduction. This is a publication / release version of the WebCGM 2.1 Test Suite (WebCGM21TS). This release covers all of the functionality of the WebCGM20TS, plus the additional functionality has been added to the 2.1 version of WebCGM profile. Please download the ZIP file and see the Release Notes.

Future releases are anticipated, with further improvements, bug fixes, etc.

Copyright & License. The WebCGM21TS adds 42 new tests to the existing 300 tests of WebCGM20TS. These tests were developed by the OASIS CGM Open WebCGM Technical Committee. OASIS copyright rules apply to these tests, Copyright � OASIS Open 2009-2010. All Rights Reserved.

The core of the WebCGM 2.1 Test Suite (WebCGM21TS) is the WebCGM 2.0 Test Suite (WebCGM20TS). The core of the WebCGM20TS is the WebCGM10TS. The WebCGM10TS was developed by Lofton Henderson and NIST (National Institute of Standards and Technology). CGM Open has provided a Web location for free distribution of the WebCGM10TS since its first publication. Copyright of the WebCGM10TS is held by Lofton Henderson. License terms for use and redistribution are free, subject to a no-modification restriction (to preserve the integrity of WebCGM10TS materials). See the WebCGM10TS copyright & license document.

Other than those tests that comprise the WebCGM10TS, all tests in the WebCGM21TS were developed by the OASIS CGM Open WebCGM Technical Committee. OASIS copyright rules apply to these tests, Copyright � OASIS Open 2006-2010. All Rights Reserved.

About.

Composition. The composition of the WebCGM 2.1 test suite is as follows:

• WebCGM21TS (~345 tests)
  • WebCGM21 add-on module (~42 tests)
  • WebCGM20TS (~300 tests)
    • WebCGM20 add-on module (~43 tests)
    • WebCGM10TS (~257 tests)
      • WebCGM10 static tests (~232 tests)
      • WebCGM10 dynamic tests (~25 tests)

Test versions. In the WebCGM 2.1 profile, there is a conformance rule that the metafile must be identified by the "ProfileEd:2.1" string. A similar rule is present in the WebCGM 2.0 profile ("ProfileEd:2.0"), and the WebCGM 1.0 profile ("ProfileEd:1.0"). Except for this requirement, most valid 1.0 and 2.0 metafiles would be valid 2.1 metafiles. I.e., if their identifer string were changed to 2.1, they would be valid 2.1 metafiles.

In the initial releases of the WebCGM21TS, most of the files in the previous editions -- WebCGM10TS and WebCGM20TS metafiles -- have been left "as is". I.e., their identifiers have not been changed to "ProfileEd:2.1". Exceptions have been made in cases where WebCGM 2.1 has changed the associated conformance requirements in the test. In such cases, the ProfileEd has been changed to 2.1. In other words, the ProfileEd in any test of the WebCGM21TS actually denotes the oldest edition of the WebCGM profile for which the test is valid.

It is planned that a future release of this WebCGM21TS will change all files to contain "ProfileEd:2.1". Please see the Release Notes (in the downloadable ZIP file) for up-to-date information about particular Test Suite releases.

Caveats.

Please check the Release Notes (in the downloadable ZIP file) for any up-to-date information about the following Test Suite caveats.

1. Some of the dynamic tests (of WebCGM10TS subset) involve HTML as either a source or destination of hyperlinks. In some cases, the HTML text was borrowed from the WebCGM 1.0 specification. Some of these HTML snippets have not yet been updated by the corresponding snippets from WebCGM 2.1. Although the tests are functionally correct, the ultimate goal is to update all of those snippets for clarity and cosmetic reasons.
2. Some CGMs and PNG reference images still reflect pre-release version numbers, e.g.," 0.9". The tests are functionally correct, and this cosmetic defect may be fixed in a future release.
3. The Dynamic (hyperlinking) tests (of WebCGM10TS subset) may not look very good if you are running on a small screen, or at less that 1024x768 resolution. (At higher resolutions, there may also be some frame-layout issues).
4. In a some cases, production of reference images was problematical for WebCGM20TS (as well as WebCGM10TS), due to limited access to high-resolution systems and tools. This may be addressed in a future release. This is not a critical criterion for the dynamic10 tests, in particular, and there is a caveat at the end of each Operator Script.

Installation Instructions. To view WebCGM21TS, all you have to do is unzip the downloadble ZIP file into a local directory. Be sure to pay attention to these details when un-zipping:

• The destination directory should be the local directory which you want to be the root of your installation of the test suite.
• Sub-directories 'static10', 'dynamic10', '20tests', and 'new21tests' will be created, and there will be further sub-directories in these.
• Be sure that your unzip operation is done with the option "Use folder names", or equivalent, so that the sub-directories are created and populated.

After you have successfully unzipped the contents:

1. open "introPage.html" in a browser, or navigate there from this page (Overview.html)
2. click the link to the dynamic module, the static-graphics module, the 20tests, or the new21tests
3. If you choose "Dynamic", this will display a Table of Contents of test cases. Select any one.
4. If you choose "20tests", this will display a Table of Contents of test cases of the WebCGM20 add-on module (see About). Select any one.

   If you choose "21tests", this will display a Table of Contents of new WebCGM 2.1 test cases. Select any one.

5. You will need a WebCGM plug-in at this point (selecting tests from the TOCs).
6. If you select "Static", then you will be taken to a Javascript page (this will not work in older versions of Netscape Navigator -- you may have to switch to Internet Explorer or another browser).
7. You can navigate to any one of the 200+ static tests, by one of several selection categories.
8. The Operator Script will be displayed, plus a button to display the (raster) reference image. You will have to cause your viewer (plugin, or standalone, or...) to display the CGM.

Dynamic10 Contents. Test cases have names like: linking-basicH2C-BE-01. The first bit is the functional category, the second is the specific focus, the third is test type (all of these are BE, Basic Effectivity), the 4th is a sequence (within category): category-focus-BE-nn.. All of the tests are BE tests. They try to provide a complete coverage of V4 functionality at a basic level of detail -- no drill down or detailed testing (DT).

When you select a test in the TOC, a 4-frame screen will come up.

• The top frame contains the test case name, and a link (not yet implemented) to the spec reference associated with the test case.
• The bottom frame contains the navigation bar, which allows you to go to the previous test, next test, or back to the TOC (the child and parent buttons are not implemented). Also, the Operator Script, which tells you how to execute the test and what to look for in the way of pass/fail.
• The right frame is generally where the test root will appear (HTML or CGM file).
• The left frame initially displays a PNG reference image of a correct result of executing the test. (In some cases, it will also subsequently be the target frame for linked content.)

For information (but not relevant to viewing and using the test suite), the test cases are each driven off of an XML test case description instance, and XSLT stylesheets generate the test harnesses.

There are many files associated with each test case. You don't need to worry much about most of them. But a couple of files might interest you. The test content root file will generally be named "category-focus-BE-nn" with extension .cgm or .html. If the test case has a target file for a link, it will be named something line "category-focus-BE-nn-target", with extension .cgm or .html. All of the files with bits like "-dyn" as a suffix to the name are associated with the harness, and you shouldn't need to worry about them.

WebCGM 2.0 tests. The majority of these are DOM and XCF tests, that each start with an HTML page. Typically there is a reference picture (PNG) on one side, a frame for display of the subject source metafile the other side, and an HTML table below, with interactive buttons for triggering DOM calls.

WebCGM 2.1 tests. These are mostly tests for the functionality added to WebCGM by the 2.1 edition. Each start with an HTML page. Typically there is a reference picture (PNG) on one side, a frame for display of the subject source metafile the other side, and an HTML table below, with interactive buttons for triggering the various sub-tests.

Download. You can download a ZIP file and install the test suite on a local computer.

View Intro Page. Download the ZIP file, install it per the above instructions, and initiate viewing at introPage.html. Either way, if you view the Intro page, it will have links that take you to the various parts of the suite. Please note viewer and browser requirements discussed above.
