the name of an internal Scilab module ("core", "time", ...), a sub-module (e.g. "optimization|neldermead").
the name of an ATOMS module ("module_lycee", "nisp", ...). To be taken into account, the module must be loaded when test_run() is called.
the absolute directory path of a module containing test/unit_tests or test/nonreg_tests.
A string array or
"": The names of the tests to execute during this run. If

The error output stream is not checked. This option can be used when Scilab complains about the localization being not available.

Does not display statistics nor execution time after execution (only number of executed, passed, failed and skipped tests will be displayed on a single line).
Export to a XML file the result of the test. This file follows the specification of the XUnit format. Note that the usage of this option enables
If the file pointed by
exportToFilealready exists, the new results are appended to the existing file.
Boolean value Returns %t if no error has been detected Returns %f if any error has been detected
Search for .tst files in the unit test and non-regression test library, execute them, and display a report about success or failures. The .tst files are searched in directories ~/tests/unit_tests" and ~/tests/nonreg_tests" where "~" is the root directory of targeted modules.
test_run checks that a test does not produce an error.
test_run checks that the output and commands of a script are
identical to the reference file. Whenever a test is executed, a
file is generated which contains
the full list of commands executed along with messages that appear in the
console output. When the script is done, the
.dia file is compared with
.dia.ref file which is expected to be in the same directory
as the .tst file. If the two file are different, the test fails.
Special tags may be inserted in the .tst file, which help to control the processing of the corresponding test. These tags are expected to be found in Scilab comments.
These are the available tags:
<-- INTERACTIVE TEST --> This test will be skipped because it is interactive.
<-- LONG TIME EXECUTION --> This test will be skipped because it needs long-time duration. To enable the test, call test_run with the following option: "enable_lt"
<-- NOT FIXED --> This test will be skipped because it is a known, but unfixed bug.
<-- TEST WITH GRAPHIC --> This test will be executed with scilab -nw. (default mode)
<-- NO TRY CATCH -->
<-- NO CHECK ERROR OUTPUT --> The error output file is not checked
<-- NO CHECK REF --> The .dia and the .dia.ref files are not compared.
<-- ENGLISH IMPOSED --> This test will be executed with the -l en_US option.
<-- FRENCH IMPOSED --> This test will be executed with the -l fr_FR option.
<-- CLI SHELL MODE --> (was <-- JVM NOT MANDATORY --> and is obsolete) This test will be executed with scilab -nwni. All tests without this, will not be executed in "mode_mwni".
<-- WINDOWS ONLY --> If the operating system isn't Windows, the test is skipped.
<-- UNIX ONLY --> If the operating system isn't an Unix OS, the test is skipped.
<-- LINUX ONLY --> If the operating system isn't GNU/Linux, the test is skipped.
<-- MACOSX ONLY --> If the operating system isn't Mac OS X, the test is skipped.
<-- XCOS TEST --> This test will launch all the necessary Xcos libs. This test will be launched in nw mode.
Each test is executed in a separated process, created with the "host" command. That enables the current command to continue, even if the test as created an unstable environment. It also enables the tests to be independent from one another.
It may happen that the output of a test depends on the platform on which it is
executed. In this case, the
.ref file cannot be correct for
all platforms and unit tests may fail for some platform. In this case, we can
create a default
.ref and create additional
file for each platform.
The various platform-specific
.ref files must have one of the following extensions.
.unix.dia.reffor Unix platform,
.linux.dia.reffor GNU/Linux platform,
.linux32.dia.reffor GNU/Linux platform with 32bits processors,
.win.dia.reffor Windows platform,
.win32.dia.reffor Windows platform with 32bits processors,
.macosx.dia.reffor Mac OS X platform.
The algorithm is the following.
.ref is considered. If this file does not exist,
platform.ref file is examined depending on the current platform.

The tests are performed in the temporary directory, not in the directory which originally contain the tests files.
The .tst script is not run as is. Instead, a header and a footer are inserted at the beginning and at the end of the .tst at the time the script is copied into the temporary directory. The role of this modification is to redirect the output messages into the .dia file, so that the user can have a log file once the test is performed.
An execution timeout delay (watchdog timer) is setup to 5 minutes
for each regular test. To ignore this timeout use the long-time
