erlang module named <c>ct</c>. The ct_run program
is compiled for the underlying operating system (e.g. Unix/Linux
or Windows) during the build of the Erlang/OTP system, and is
@@ -43,67 +43,10 @@
The <c>ct</c> interface functions can be called from the Erlang shell,
or from any Erlang function, on any supported platform.</p>
- <p>A legacy Bourne shell script - named run_test - exists,
- which may be manually generated and installed. This script may be used
- instead of the ct_run program mentioned above, e.g. if the user
- wishes to modify or customize the Common Test start flags in a simpler
- way than making changes to the ct_run C program.</p>
-
<p>The Common Test application is installed with the Erlang/OTP
system and no additional installation step is required to start using
- Common Test by means of the ct_run executable program, and/or the interface
- functions in the <c>ct</c> module. If you wish to use the legacy Bourne
- shell script version run_test, however, this script needs to be
- generated first, according to the instructions below.</p>
-
- <note><p>Before reading on, please note that since Common Test version
- 1.5, the run_test shell script is no longer required for starting
- tests with Common Test from the OS command line. The ct_run
- program (descibed above) is the new recommended command line interface
- for Common Test. The shell script exists mainly for legacy reasons and
- may not be updated in future releases of Common Test. It may even be removed.
- </p></note>
-
- <p>Optional step to generate a shell script for starting Common Test:</p>
- <p>To generate the run_test shell script, navigate to the
- <c><![CDATA[common_test-<vsn>]]></c> directory, located among the other
- OTP applications (under the OTP lib directory). Here execute the
- <c>install.sh</c> script with argument <c>local</c>:</p>
-
- <p><c>
- $ ./install.sh local
- </c></p>
-
- <p>This generates the executable run_test script in the
- <c><![CDATA[common_test-<vsn>/priv/bin]]></c> directory. The script
- will include absolute paths to the Common Test and Test Server
- application directories, so it's possible to copy or move the script to
- a different location on the file system, if desired, without having to
- update it. It's of course possible to leave the script under the
- <c>priv/bin</c> directory and update the PATH variable accordingly (or
- create a link or alias to it).</p>
-
- <p>If you, for any reason, have copied Common Test and Test Server
- to a different location than the default OTP lib directory, you can
- generate a run_test script with a different top level directory,
- simply by specifying the directory, instead of <c>local</c>, when running
- <c>install.sh</c>. Example:</p>
-
- <p><c>
- $ install.sh /usr/local/test_tools
- </c></p>
-
- <p>Note that the <c><![CDATA[common_test-<vsn>]]></c> and
- <c><![CDATA[test_server-<vsn>]]></c> directories must be located under the
- same top directory. Note also that the install script does not copy files
- or update environment variables. It only generates the run_test
- script.</p>
-
- <p>Whenever you install a new version of Erlang/OTP, the run_test
- script needs to be regenerated, or updated manually with new directory names
- (new version numbers), for it to "see" the latest Common Test and Test Server
- versions.</p>

+ When a test case (or configuration function) fails
+ because of an exit signal from a linked process, Common
+ Test previously passed only the reason for process
+ termination to the CT post hook functions and the event
+ handlers (in the tc_done event). This has been changed so
+ that now the tuple {'EXIT',ReasonForProcessTermination}
+ is passed instead. This makes it much easier in the CT
+ post hook functions to distinguish a failure of this sort
+ from other types of errors and from the return value of a

+ buffer. The polling is controlled by two new telnet
+ config values, which are documented in the ct_telnet
+ reference manual. The polling mechanism is disabled by
+ default (making the get_data/1 function backwards
+ compatible).</p>
