|
<p>The cintltst Test Suite contains all the tests for International
|
|
Components for Unicode C API. These tests may be automatically run by typing
|
|
"cintltst" or "cintltst -all" at the command line. It
|
|
depends on the C Test Framework. <br>
|
|
"cintltst"<br>
|
|
or<br>
|
|
"cintltst -all"</p>
|
|
|
|
<h3>C Test FrameWork</h3>
|
|
|
|
<h4>Purpose:</h4>
|
|
|
|
<p>To enable the writing of tests entirely in C. The Framework has been
|
|
designed to make creating tests or converting old ones as simple as possible,
|
|
with a minimum of framework overhead. A sample test file, <a href="#demo.c">"demo.c"</a>
|
|
is included at the end of this document. For more information regarding C test
|
|
framework, please see the directory \intlwork\source\tools\ctestfw.</p>
|
|
|
|
<h4>Writing Test Functions</h4>
|
|
|
|
<p>The format of the test functions is like the following,</p>
|
|
|
|
<pre>void some_test()</pre><pre>{</pre><pre>}</pre>
|
|
|
|
<p>Output from the test is accomplished with three printf-like functions:</p>
|
|
|
|
<pre>void log_err ( const char *fmt, ... );</pre><pre>void log_info ( const char *fmt, ... );</pre><pre>void log_verbose ( const char *fmt, ... );</pre>
|
|
|
|
<p><strong>log_info() </strong>simply writes to the console, for informational
|
|
messages.<br>
|
|
<strong>log_verbose()</strong> writes to the console ONLY if the VEBOSE flag is
|
|
turned on (or the -v option to the command line). It's useful for debugging. By
|
|
default, VERBOSE flag is turned OFF.<br>
|
|
<strong>log_error()</strong> is what should be called when a test failure is
|
|
detected. The error will be then logged and error count will be incremented by
|
|
one.</p>
|
|
|
|
<h4>Building a tree of tests</h4>
|
|
|
|
<p>To use the tests you must link them into a hierarchical structure. The root
|
|
of the structure will be allocated for you.</p>
|
|
|
|
<pre>TestNode *root = NULL; /* empty */</pre><pre>addTest( &root, &some_test, "/test");</pre>
|
|
|
|
<p>The function pointer and an absolute 'path' to the test are supplied. Paths
|
|
may be up to 127 chars in length and may be used to group tests.<br>
|
|
<br>
|
|
The calls to addTest should be placed in a function or a hierarchy of functions
|
|
(perhaps mirroring the paths), please see the following demo.c example for more
|
|
details.</p>
|
|
|
|
<h4>Running the tests</h4>
|
|
|
|
<p>A subtree may be extracted from another tree of tests for programmatic
|
|
running of subtests</p>
|
|
|
|
<pre>TestNode* sub;</pre><pre>sub = getTest(root, "/mytests");</pre>
|
|
|
|
<p>And a tree of tests may be run simply by:</p>
|
|
|
|
<pre>runTests( root ); /* or 'sub' */</pre>
|
|
|
|
<p>Similarly, showTests() will list out the tests.<br>
|
|
<br>
|
|
However, it is easier to simply run at the command prompt with the Usage
|
|
specified below.</p>
|
|
|
|
<h4>Globals</h4>
|
|
|
|
<p>The command line parser will manage resetting the error count, and printing
|
|
a summary of the failed tests. But if you call runTest directly, for instance,
|
|
you will need to manage these yourself.<br>
|
|
<strong>ERROR_COUNT</strong> contains the number of times log_err was called.
|
|
runTests resets it to zero before running the tests.<br>
|
|
<strong>VERBOSITY</strong> should be 1 to allow log_verbose() data to be
|
|
displayed otherwise 0 (default).</p>
|
|
|
|
<h3>Building</h3>
|
|
|
|
<p>To compile this test suite using MSVC, follow the instructions in <a
|
|
href="../readme.html#HowToInstall">icu/source/readme.html#HowToInstall</a> for
|
|
building the "allC" workspace. This builds the libraries as well as
|
|
the cintltst executable.</p>
|
|
|
|
<h3>Executing</h3>
|
|
|
|
<p>To run the test suite from the command line, change directories to
|
|
"icu/source/test/cintltst/Debug" for the debug build, (or
|
|
"icu/source/test/cintltst/Release" for the releawse build) then type:<br>
|
|
"cintltst".</p>
|
|
|
|
