=head1 DESCRIPTION

The B<xcattest> command runs test cases to verify the xCAT functions. It can be used to ensure the code changes you made do not break the existing commands; to run acceptance test for new build you got; to verify the xCAT snapshot build or development build before putting it onto your production system. The B<xcattest> command is part of the xCAT package I<xCAT-test>.

The root directory for the I<xCAT-test> package is I</opt/xcat/share/xcat/tools/autotest/>. All test cases are in the sub directory I<testcase>, indexed by the xCAT command, you can add your own test cases according to the test cases format below. The subdirectory I<bundle> contains all the test cases bundle definition files, you can customize or create any test cases bundle file as required. The testing result information will be written into the subdirectory I<result>, the timestamps are used as the postfixes for all the result files. I<xCAT-test> package ships two configuration file templates: I<aix.conf.template> and I<linux.conf.template> for AIX and Linux environment, you can use the template files as the starting point of making your own configuration file.

=head1 OPTIONS

=over 10

=item B<-?|-h>

Display usage message.

=item B<-f> I<configure file>

Specifies the configuration file with full-path. If not specified, an example config file: I</opt/xcat/share/xcat/tools/autotest/linux.conf.template> is used by default. If B<System> tag is used, only I<[System]> section in the configuration file will be used. If B<System> is not used, all other sections of the configuration file will be used, like I<[Table]>, I<[Object]>, etc.

=item B<-b> I<testcase bundle list>

Comma separated list of test case bundle files, each test cases bundle can contain multiple lines and each line for one test case name. The bundle files should be placed in I</opt/xcat/share/xcat/tools/autotest/bundle>.

=item B<-t> I<testcase name list>

Comma separated list of test cases to run.

=item B<-c> I<testcase command list>

Comma separated list of commands which will be tested, i.e., all the test cases under the command sub directory will be run.

=item B<-s> I<filter expression>

Run testcases with testcase B<label> attribute matching I<filter expression>. Operators B<|>, B<+>, and B<-> can be used. Expresson I<"label1+label2-label3|label4|label5"> will match testcases that have B<label> attribute matching "label1" and "label2", but not "label3" or testcases that have B<label> attribute matching "label4" or testcases that have B<label> attribute matching "label5"

=item B<-l {caselist|caseinfo|casenum|bundleinfo}>

Display rather than run the test cases. The B<caselist> is a default and will display a list of testcase names. B<caseinfo> will display testcase names and descriptions. B<casenum> will display the number of testcases. B<bundleinfo> will display testcase bundle names and descriptions.


=item B<-r>

Back up the original environment settings before running test, and restore them after running test.

=item B<-q>

Do not print output of test cases to STDOUT, instead, log output to I</opt/xcat/share/xcat/tools/autotest/result>.

=head1 RETURN VALUE

0 The command completed successfully.

1 An error has occurred.

=head1 TEST CASE FORMAT

The xCAT-test test cases are in flat text format, the testing framework will parse the test cases line by line, here is an example of the test case:

  #required, case name
  start:case name
  #optional, description of the test case
  description: what the test case is for?
  #optional, environment requirements
  os:AIX/Linux
  #optional, environment requirements
  arch:ppc/x86
  #optional, environment requirements
  hcp:hmc/mm/bmc/fsp
  #optional, label
  label:label1
  #required, command need to run
  cmd:comand
  #optional, check return code of last executed command
  check:rc == or != return code
  #optional, check output of last executed command
  check:output== or != or =~ or !~ output check string
  end

B<Note>: Each test case can have more than one I<cmd> sections and each I<cmd> section can have more than one I<check:rc> sections and more than one I<check:output> sections, the I<output check string> can include regular expressions.

=head1 EXAMPLES

=over 4

=item 1.

To run all  test cases related command rpower:

  xcattest -f /tmp/config -c rpower

=item 2.

To run customized bundle with /tmp/config file:

  xcattest -c lsdef -l  > /opt/xcat/share/xcat/tools/autotest/bundle/custom.bundle
  Modify custom.bundle
  xcattest -f /tmp/config -b custom.bundle

=item 3.

To run specified test cases with /tmp/config file:

  xcattest -f /tmp/config -t lsdef_t_o_l_z

=item 4.

To add a new case to test B<chvm>. In the example, we assume that the min_mem should not be equal to 16 in the lpar profile of computenode. The case name is chvm_custom. It create a test lpar named testnode firstly, that change the min_mem of the lpar to 16 using chvm, then check if min_mem have changed correctly. At last, the testnode be remove to ensure no garbage produced in the cases.

  add a new test case file in /opt/xcat/share/xcat/tools/autotest/chvm
  edit filename
  start:chvm_custom
  hcp:hmc
  cmd:lsvm $$CN > /tmp/autotest.profile
  check:rc==0
  cmd:mkdef -t node -o testnode mgt=hmc groups=all
  cmd:mkvm testnode -i $$MaxLparID -l $$CN
  check:rc==0
  cmd:perl -pi -e 's/min_mem=\d+/min_mem=16/g' /tmp/autotest.profile
  cmd:cat /tmp/autotest.profile|chvm testnode
  check:rc==0
  cmd:lsvm testnode
  check:output=~min_mem=16
  cmd:rmvm testnode
  cmd:rm -f /tmp/autotest.profile
  end

=item 5.

To run all test cases that have I<label:kdump> or I<label:parallel_cmds>:

  xcattest -s kdump|parallel_cmds

=item 6.

To display all bundles and their descriptions:

  xcattest -l bundleinfo

=back

=head1 INLINE FUNCTIONS

The xCAT-test testing framework provides some inline functions. The inline functions can be called in test cases as __FUNCTIONNAME(PARAMTERLIST)__ to get some necessary attributes defined in the configuration file. The inline functions can be used in I<cmd> section and the I<check:output> section.

=over 4

=item 1. 

B<GETNODEATTR(nodename, attribute)> To get the value of specified node's attribute

=item 2. 

B<INC(digit)> To get value of digit+1.

For example, to run B<rscan> command against the hardware control point of compute node specified in the configuration file:

  rscan __GETNODEATTR($$CN, hcp)__ -z

=item 3. 

B<GETTABLEVALUE(keyname, key, colname, table)> To get the value of column where keyname == key in specified table.
