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