It tests the LayoutEngine's 19API and reads an XML file that contains test cases to test some of 20the features of the LayoutEngine. These test cases are not 21comprehensive, but they do test the most important features of 22 the LayoutEngine. When you have successfully run letest, you 23can use the ICU LayoutEngine in you application knowing that the 24basic functionality is working correctly.<br> 25<p>gendata is a program that is used by the ICU team to build the 26file letest.xml which contains the test cases. Unless you have 27changed your copy of the LayoutEngine and want to validate the 28changes on other platforms, there's no reason for you to run this 29program.</p> 30<p>(The ICU team first runs a Windows application which uses the 31ICU LayoutEngine to display the text that letest uses. Once it has 32been verified that the text is displayed correctly, gendata is run 33to produce letest.xml, and then letest is run on Windows to verify 34that letest still works with the new data.)<br></p> 35<h2>How do I build letest?</h2> 36First, you need to build ICU, including the LayoutEngine. 37<p>On Windows, letest is part of the allinone project, so a normal 38build of ICU will also build letest. On UNIX systems, connect to 39<top-build-dir>/test/letest and do "make all" .<br></p> 40<h2>How do I run letest?</h2> 41Before you can run letest, you'll need to get the fonts it uses. 42For legal reasons, we can't include most of them with ICU, but you 43can download them from the web. To do this, you'll need access to a 44computer running Windows. All of the fonts should be stored in 45<icu>/source/test/testdata. Here's how to get the fonts: 46<p>Download a recent version of the Java 2 Platform, Standard 47Edition (J2SE) from <a href= 48"http://java.sun.com/javase/downloads/index.html">java.sun.com</a>. 49Click on the "Download" button for the version of Java that you 50want to download. The page offers both JDKs and JREs. (The JRE is 51sufficient for letest.) The download page will have a link to the 52license agreement. Be sure to read and understand the license 53agreement, and then click on the Accept button. Download the 54package and install it. You'll need one font. On Windows, it will 55be in, for example, "C:\Program Files\Java\jdk1.6.0\jre\lib\fonts". 56The file you want is "LucidaSansRegular.ttf". Copy this file into 57the directory from which you'll run letest.<br></p> 58<p>Next is the Hindi font. Go to the NCST site and download 59<a href="http://tdil.mit.gov.in/download/Raghu.htm">raghu.ttf</a>. 60When you hit the DOWNLOAD button on the page, it will open another 61window which contains a disclaimer and a license agreement. Be sure 62that you understand and agree to all of this before you download 63the font. You can download raghu.ttf into the directory from which 64you'll run letest.<br></p> 65<p>Then download the Thai font. Go to <a href= 66"http://www.into-asia.com/thai_language/thaifont/">into-asia.com</a> 67and click on the link for the Angsana font. This will download a 68.ZIP file. Extract the font file, angsd___.ttf, into the directory 69from which you will run letest.<br></p> 70<p>There's still one more font to get, the Code2000 Unicode font. 71Go to James Kass' <a href="http://www.code2000.net/">Unicode 72Support In Your Browser</a> page and click on the link that says 73"Click Here to download Code2000 shareware demo Unicode font." This 74will download a .ZIP file which contains CODE2000.TTF and 75CODE2000.HTM. Expand this .ZIP file and put the CODE2000.TTF file 76in the directory from which you'll run letest.<br></p> 77<p><span style="font-weight: bold;">Note:</span> The Code2000 font 78is shareware. If you want to use it for longer than a trial period, 79you should send a shareware fee to James. Directions for how to do 80this are in CODE2000.HTM.</p> 81<p>letest.xml references three other fonts:</p> 82<ul> 83<li>ARIALUNI.TTF is Microsoft's Arial Unicode MS font, which is 84distributed with Microsoft Office and is licensed only for use on 85the Windows operating system.</li> 86<li>Devamt.ttf is a proprietary font which cannot be freely 87downloaded.</li> 88<li>TestFont1.otf is included with ICU.</li> 89</ul> 90To run letest type CTRL+F5 in Visual Studio, or "make check" in 91UNIX. If everything's OK you should see something like this: 92<blockquote><tt> /<br> 93 /api/<br> 94 ---[OK] ---/api/ParameterTest<br> 95 ---[OK] ---/api/FactoryTest<br> 96 /layout/<br> 97 ---[OK] ---/layout/AccessTest<br> 98 ---[OK] ---/layout/DataDrivenTest<br> 99 /c_api/<br> 100 ---[OK] ---/c_api/ParameterTest<br> 101 ---[OK] ---/c_api/FactoryTest<br> 102 /c_layout/<br> 103 ---[OK] ---/c_layout/AccessTest<br> 104 ---[OK] ---/c_layout/DataDrivenTest<br> 105<br> 106[All tests passed successfully...]<br> 107Elapsed Time: 00:00:00.351<br></tt></blockquote> 108If letest cannot open a font, it will print a warning message and 109skip the test. letest will also check the version of the font you 110have to make sure it's the same one that was used to generate the 111test case. If the version doesn't match, letest will print a 112warning message and proceed with the test.<br> 113</body> 114</html> 115
