<dt><b>DESCRIPTION</b></dt>
|
|
<dd>
|
|
<b>jsDriver.pl</b> is normally used to run a series of tests against
|
|
one of the JavaScript shells. These tests are expected to be laid out
|
|
in a directory structure exactly three levels deep. The first level
|
|
is considered the <b>root</b> of the tests, subdirectories under the
|
|
<b>root</b> represent <b>Test Suites</b> and generally mark broad
|
|
categories such as <i>ECMA Level 1</i> or <i>Live Connect 3</i>. Under the
|
|
<b>Test Suites</b> are the <b>Test Categories</b>, which divide the
|
|
<b>Test Suite</b> into smaller categories, such as <i>Execution Contexts</i>
|
|
or <i>Lexical Rules</i>. Testcases are located under the
|
|
<B>Test Categories</b> as normal JavaScript (*.js) files.
|
|
<p>
|
|
If a file named <b>shell.js</b> exists in either the
|
|
<b>Test Suite</b> or the <b>Test Category</b> directory, it is
|
|
loaded into the shell before the testcase. If <b>shell.js</b>
|
|
exists in both directories, the version in the <b>Test Suite</b>
|
|
directory is loaded <i>first</i>, giving the version associated with
|
|
the <b>Test Category</b> the ability to override functions previously
|
|
declared. You can use this to
|
|
create functions and variables common to an entire suite or category.
|
|
<p>
|
|
Testcases can report failures back to <b>jsDriver.pl</b> in one of
|
|
two ways. The most common is to write a line of text containing
|
|
the word <code>FAILED!</code> to <b>STDOUT</b> or <b>STDERR</b>.
|
|
When the engine encounters a matching line, the test is marked as
|
|
failed, and any line containing <code>FAILED!</code> is displayed in
|
|
the failure report. The second way a test case can report failure is
|
|
to return an unexpected exit code. By default, <b>jsDriver.pl</b>
|
|
expects all test cases to return exit code 0, although a test
|
|
can output a line containing <code>EXPECT EXIT <i>n</i></code> where
|
|
<i>n</i> is the exit code the driver should expect to see. Testcases
|
|
can return a nonzero exit code by calling the shell function
|
|
<code>quit(<i>n</i>)</code> where <code><i>n</i></code> is the
|
|
code to exit with. The various JavaScript shells report
|
|
non-zero exit codes under the following conditions:

|

Bugzilla URL. When a testcase writes a line in the format
|
|
<code>BUGNUMBER <i>n</i></code> to <b>STDOUT</b> or <b>STDERR</b>,
|
|
<b>jsDriver.pl</b> interprets <code><i>n</i></code> as a bugnumber
|
|
in the <a href="http://bugzilla.mozilla.org">BugZilla</a> bug
|
|
tracking system. In the event that a testcase which has specified
|
|
a bugnumber fails, a hyperlink to the BugZilla database
|
|
will be included in the output by prefixing the bugnumber with the
|
|
URL specified here. By default, URL is assumed to be
|
|
"http://bugzilla.mozilla.org/show_bug.cgi?id=".

Classpath to pass the the Java Virtual Machine. When running tests

against the <b>Rhino</b> engine, PATH will be passed in as the value

|
to an argument named "-classpath". If your particular JVM
|
|
does not support this option, it is recommended you specify your

class path via an environment setting. Refer to your JVM

documentation for more details about CLASSPATH.

<dt><b>-f FILE, --file=FILE</b></dt>

<dd>
|

Generate html output to the HTML file named by FILE. By default,
|
|
a filename will be generated using a combination of the engine type
|
|
and a date/time stamp, in the format:
|
|
<code>results-<i><engine-type></i>-<i><date-stamp></i>.html</code>

<dd>
|

Set the location of the Java Virtual Machine to use when running

tests against the <b>Rhino</b> engine. This can be used to test
|
|
against multiple JVMs on the same system.
|

<br>
|

<br>
|
|
<dt><b>-k, --confail</b></dt>
|
|
<dd>
|
|
Log failures to the console. This will show any failures, as they
|
|
occur, on <b>STDERR</b> in addition to creating the HTML results
|
|
file. This can be useful for times when it may be
|
|
counter-productive to load an HTML version of the results each time
|
|
a test is re-run.
|
|
<br>
|
|
<br>
|
|
<dt><b>-l FILE ..., --list=FILE ...</b></dt>
|
|
<dd>
|
|
Specify a list of tests to execute. FILE can be a plain text file
|
|
containing a list of testcases to execute, a subdirectory
|
|
in which to
|
|
<a href="http://www.instantweb.com/~foldoc/foldoc.cgi?query=grovel">grovel</a>
|
|
for tests, or a single testcase to execute. Any number of FILE
|
|
specifiers may follow this option. The driver uses the fact that a
|
|
valid testcase should be a file ending in .js to make the distinction
|
|
between a file containing a list of tests and an actual testcase.
|
|
<br>
|
|
<br>
|
|
<dt><b>-L FILE ..., --neglist=FILE ...</b></dt>
|
|
<dd>
|
|
Specify a list of tests to skip. FILE has the same meaning as in
|
|
the <b>-l</b> option. This option is evaluated after
|
|
<b>all</b> <b>-l</b> and <b>--list</b> options, allowing a user
|
|
to subtract a single testcase, a directory of testcases, or a
|
|
collection of unrelated testcases from the execution list.
|
|
<br>
|
|
<br>
|
|
<dt><b>-p PATH, --testpath=PATH</b></dt>
|

<dd>

default this is ./

|
|
<br>
|
|
<dt><b>-s PATH, --shellpath=PATH</b></dt>
|
|
<dd>
|
|
Directory holding the JavaScript shell. This can be used to override
|
|
the automatic shell location <b>jsDriver.pl</b> performs based on
|
|
you OS and engine type. For Non <b>Rhino</b> engines, this
|
|
includes the name of the executable as well as the path. In
|
|
<b>Rhino</b>, this path will be appended to your
|
|
<a href="#classpath">CLASSPATH</a>. For the
|
|
<b>SpiderMonkey</b> shells, this value defaults to
|
|
../src/<Platform-and-buildtype-specific-directory>/[js|jsshell],
|
|
for the
|
|
<b>LiveConnect</b> shells,
|
|
../src/liveconnect/src/<Platform-and-buildtype-specific-directory>/lschell
|
|
and for the <b>xpcshell</b> the default is the value of your
|
|
<code>MOZILLA_FIVE_HOME</code> environment variable. There is no
|
|
default (as it is usually not needed) for the <b>Rhino</b> shell.
|
|
<br>
|
|
<br>
|
|
<dt><b>-t, --trace</b></dt>
|
|
<dd>
|
|
Trace execution of <b>jsDriver.pl</b>. This option is primarily
|
|
used for debugging of the script itself, but if you are interested in
|
|
seeing the actual command being run, or generally like gobs of
|
|
useless information, you may find it entertaining.

<dt><b>-u URL, --lxrurl=URL</b></dt>

|
|
<b>jsDriver.pl</b> requires the
|
|
<a href="http://search.cpan.org/search?module=Getopt::Mixed">Getopt::Mixed</a>
|
|
perl package, available from <a href="http://www.cpan.org">cpan.org</a>.
|
|
<br>
|
|
<br>
|
|
<dt><b>EXAMPLES</b></dt>
|
|
<dd>
|
|
<code>perl jsDriver.pl -e smdebug -L lc*</code><br>
|
|
Executes all tests EXCEPT the liveconnect tests against the
|
|
SpiderMonkey debug shell, writing the results
|
|
to the default result file. (NOTE: Unix shells take care of wildcard
|
|
expansion, turning <code>lc*</code> into <code>lc2 lc3</code>. Under
|
|
a DOS shell, you must explicitly list the directories.)
|
|
<p>
|
|
<code>perl jsDriver.pl -e rhino -L rhino-n.tests</code><br>
|
|
Executes all tests EXCEPT those listed in the
|
|
<code>rhino-n.tests</code> file.
|
|
<p>
|
|
<code>perl -I/home/rginda/perl/lib/ jsDriver.pl -e lcopt -l lc2
|
|
lc3 -f lcresults.html -k</code><br>
|
|
Executes ONLY the tests under the <code>lc2</code> and <code>lc3</code>
|
|
directories against the LiveConnect shell. Results will be written to
|
|
the file <code>lcresults.html</code> <b>AND</b> the console. The
|
|
<code>-I</code> option tells perl to look for modules in the
|
|
<code>/home/rginda/perl/lib</code> directory (in addition to the
|
|
usual places), useful if you do not have root access to install new
|
|
modules on the system.
