NAME

       jtreg - Regression Test Harness

DESCRIPTION

Usage:
jtreg options... tests...

Tests can be given as files or folders containing test files, or by means of test groups. Long lists of
options and tests may be encapsulated in "at-files".

Verbose Options

These options control the amount of output written to the console while running tests

-v | --v:<value> | -verbose | --verbose:<value>
Increase the amount of output written to the console. A value, or selected combinations of values
separated by commas, may be given to select the type of output desired.

default
Three lines of output per test: start, end, status

summary
One line of output per test: status, test name

all Selected contents of JTR file for all tests (includes stdout/stderr)

pass Selected contents of JTR file for passed tests

fail Selected contents of JTR file for failed tests

error Selected contents of JTR file for errored tests

nopass Suppress output for tests that passed

time Elapsed time per action

multirun
Updates for each testsuite when tests from more than one are being executed.

-v1 Short for -verbose:summary

-va Short for -verbose:all

-ve Short for -verbose:error

-vf Short for -verbose:fail

-vp Short for -verbose:pass

-vt Short for -verbose:time

Documentation Options

Options for additional documentation

--help [words...] | -h [words...] | -help [words...] | -usage [words...]
Command line help. Give words to see help info containing those or use "-help all" to see all
available help.

-n | -relnote
Release notes

-t | -tagspec
Tag specification supported by this implementation

-version
Give information about the version of jtreg in use.

General Options

-allowSetSecurityManager | --allowSetSecurityManager:<boolean-value>
Allow sameVM tests to set a security manager. Default is "yes" if option not given or no value
given for option.

yes Allow sameVM tests to set a security manager

no Do not allow sameVM tests to set a security manager

on Allow sameVM tests to set a security manager

off Do not allow sameVM tests to set a security manager

true Allow sameVM tests to set a security manager

false Do not allow sameVM tests to set a security manager

-c | -check
Verify correctness of test descriptions. Does NOT run tests.

-conc:<factor> | -concurrency:<factor>
concurrency factor

-dir:<dir>
Specify a base directory for test files and directories

-e:name[=value][,name[=value]...]
Specify additional environment variables to be passed to each test. If a value is not given for a
name, the current value of the environment variable will be used. Standard environment variables,
like DISPLAY, LANG, windir, SystemRoot, etc, will automatically be given to each test, if they are
set in the current environment.

-g | -gui
Access regression extensions via the standard JavaTest harness gui

-ignore:<value>
Specify how to handle tests containing an @ignore tag.

quiet Completely ignore such tests.

error (Default.) Execute the actions up to the @ignore tag, then give an "Error" result.

run Run the test, as though the @ignore tag were not present.

-l | -listtests
List the tests that would be executed instead of executing them.

-lock:<file>
Lock file to use for tests in "exclusive access" directories when running tests in multiple
concurrent instances of jtreg.

-nativepath:<path>
Path to location of native libraries and programs needed by the tests.

-noignore
suppress the effect of any @ignore tags, allowing the test to proceed as if the @ignore tags were
not present. Deprecated: see the -ignore option.

-nr | -noreport
Do not generate a final report.

-o:<classname> | -observer:<classname>
Specifies the class to observe the progress of a test suite; the class must implement a specific
interface; contact a developer for details. E.g. -o:SampleRegressionObserver

-od:<path> | -observerDir:<path> | -op:<path> | -observerPath:<path>
Specifies the pathname of a directory or .jar file in which the observer class is located. The
given pathname is simply appended to the CLASSPATH used for the tests, thus care should be taken
when naming an observer not to collide with the names of classes internal to the JavaTest harness
or the JRE, e.g., put the observer class in its own named package.

-r:<directory> | -reportDir:<directory>
All report files placed here; "./JTreport" is default

-retain | --retain:<pass,fail,error,all,file-pattern>,...
Specify files to be retained after each test completes executing. If -retain is not specified,
only the files from the last test executed will be retained. If -retain is specified with no
argument, all files will be retained. Otherwise, the files may be described by one or more of the
following values:

none Do not retain any of the files generated by each test

pass Retain files generated by tests that pass

fail Retain files generated by tests that fail

error Retain files generated by tests that caused an error

all Retain all files generated by each test

file-pattern
Retain files that match a specific filename. The name may contain '*' to match any sequence of
characters. For example, result.* or *.err.

-ro | -reportOnly
Generate report for previously executed tests. This does not re-run any tests. A work directory
containing the results of the executed tests must be provided. The default location is "./JTwork".
To specify an alternate directory, use -workDir.

-show:Name of information in the results file, such as "rerun".
Show selected information from the results file for a test

-showGroups
Show the expansion (to files and directories) of the groups given on the command line. To see the
expansion of all the groups in a test suite, specify the name of the test suite.

-startHttpd
Start the http server to view test results

-w:<directory> | -workDir:<directory>
Location for .class files, .jtr files, etc. "./JTwork" is default

-xml | --xml:verify
Create ant/junit xml files into the workDir. Optionally verify if the file is well formed.

Timeout Options

These options control the behavior when tests run longer than their specified timeout value.

-th:<classname> | -timeoutHandler:<classname>
Specifies the class to handle timeouts. The class must extend
com.sun.javatest.regtest.TimeoutHandler. E.g. -th:MyHandler

-thd:<path> | -timeoutHandlerDir:<path>
Specifies the pathname of a directory or .jar file in which the timeout handler class is located.
The given pathname is simply appended to the CLASSPATH used for the tests, thus care should be
taken when naming an timeout handler not to collide with the names of classes internal to the
JavaTest harness or the JRE, e.g., put the timeout handler class in its own named package.

-thtimeout:<#seconds> | -timeoutHandlerTimeout:<#seconds>
Specifies execution time limitation for the timeout handler. If the timeout handler does not
finish its actions within the specified period of time, it will be interrupted. Non-positive
values mean no limitation. The default value is 5 minutes (300 seconds).

-timeout:<number> | -timeoutFactor:<number>
A scaling factor to extend the default timeout of all tests. Typically used when running tests on
slow systems or systems with slow file systems.

-tl:<#seconds> | -timelimit:<#seconds>
Do not run tests which specify a timeout longer than a given value. The comparison is done against
any values specified in the test, before any timeout factor is applied.

Test Selection Options

These options can be used to refine the set of tests to be executed.

-a | -automatic | -automagic
Any test with /manual will not be run

-bug:<bugid>
Run only those tests which apply to the given bugid.

-exclude:<file> | -Xexclude:<file>
Provide a file specifying tests not to be run

-k:<keywordExpr> | -keywords:<keywordExpr>
A keyword boolean expression for test selection. The expression can contain keyword names,
combined with & (and), | (or), ! (not) and parentheses.

-m | -manual
Only tests with /manual will be run

-noshell
Any tests which contain shell actions will not be run

-shell Only tests which contain shell actions will be run

-status:<value>,...
Select tests according to their result in an earlier run. The value can be one or more of the
following values, separated by commas.

pass Tests that passed

fail Tests that failed

notRun Tests that have not been run

error Tests that could not be run because of errors, or tests that were ignored

Test Mode Options

Each test consists of a series of steps, called actions. The jtreg harness provides different
modes, which determine the JVM to use to execute each action. The default is to run each action in
a new JVM.

-avm | -agentvm
Execute each action using a pool of reusable JVMs, except when an action specifies otherwise. It
provides good performance, and reasonable isolation between actions: if a JVM can be reset to a
standard state after it has been used, it will be returned to the pool for reuse; otherwise, it
will be discarded and replaced if and when necessary. This mode is generally recommended for all
use. The JDK to use can be specified with -testjdk or -jdk, except for @compile actions, which
use -compilejdk or -jdk. If values are not provided, the environment variable JAVA_HOME is used.

-ovm | -othervm
Execute every action in a new JVM. This is the default. It provides the maximum isolation between
actions, at a significant cost in performance. The JDK to use can be specified with -testjdk or
-jdk, except for @compile actions, which use -compilejdk or -jdk. If values are not provided, the
environment variable JAVA_HOME is used.

-s | -svm | -samevm
Execute each action in the same JVM as the jtreg harness, except when an action specifies
otherwise. It provides the maximum performance, but the least isolation between actions, such that
a bad test can cause all subsequent tests in the test run to fail. This mode is only suitable for
well-behaved test suites, and cannot be used in conjunction with the -concurrency option. It is no
longer recommended for general use. The JDK version used may be specified with -testjdk or -jdk.
If a value is not provided, then the JDK version will be determined by the environment variable
JT_JAVA if it is set. Otherwise, the environment variable JAVA_HOME is used.

JDK-related Options

By default, tests will be run using the default JVM in the test JDK. You can pass all applicable
JVM options via using -vmoption; in addition, many common JVM options are also supported directly.
For full details of any option, consult the documentation for that version of the JDK, or try
using "java -help" or "java -X". If an option is not applicable to a particular platform or JDK
release, it will be rejected.

--add-modules <module>(,<module>)*
root modules to resolve in addition to the initial module

-addmods <module>(,<module>)*
root modules to resolve in addition to the initial module

-agentlib:<libname><[=<options>]
Load native agent library

-agentpath:<pathname><[=<options>]
Load native agent library by full pathname

-compilejdk:<java.home>
Compile all tests using specified JDK. If not specified, tests are compiled with the JDK used to
run the tests. See also -jdk. e.g. -jdk:/usr/local/java/jdk1.5/solaris-sparc

-cpa:<path> | -classpathappend:<path>
Append the provided classPath to the CLASSPATH of every test. This is designed to be used
primarily for tests which require non-core JDK functionality. For example, to test Swing, which is
not part of core JDK1.1, the following addition to the the CLASSPATH would be necessary:
-cpa:/usr/local/java/swing-1.0.3/swingall.jar

-D<name>=<value>
Define a system property

-debug:<option>...
Use this to specify VM options to attach a debugger to a VM running a test. It is similar to
-vmoptions except that it is not used when starting VMs used to query the properties of that VM.
See also -javaoptions and -vmoptions.

-enableassertions | --enableassertions:* | -ea | --ea:* | -disableassertions

| --disableassertions:* | -da | --da:*
Enable or disable assertions

-enablesystemassertions | -esa | -disablesystemassertions | -dsa

-javacoption:<option>
Additional compiler option. You can give this option multiple times. Any embedded filenames must
be given with absolute paths.

-javacoptions:<option>...
Additional compiler options. You can give this option multiple times, or give many values
together, separated by spaces. If you give multiple values, you may need to enclose them in
quotes, depending on the shell you use. Any embedded filenames must be given with absolute paths.
Warning: do not use this form if any of the options has an argument such as a filename that might
contain spaces. In that case, use one or more -javacoption options instead.

-javaoption:<option>
Additional java option for running test classes. You can give this option multiple times. Any
embedded filenames must be given with absolute paths. See also -vmoption.

-javaoptions:<option>...
Additional java options for running test classes. You can give this option multiple times, or give
many values together, separated by spaces. If you give multiple values, you may need to enclose
them in quotes, depending on the shell you use. Any embedded filenames must be given with absolute
paths. Warning: do not use this form if any of the options has an argument such as a filename that
might contain spaces. In that case, use one or more -javaoption options instead. See also
-vmoptions.

-jdk:<java.home> | -testjdk:<java.home>
Run all tests using specified JDK. e.g. -jdk:/usr/local/java/jdk1.5/solaris-sparc

-jit Enable the JIT for the tests. The JIT is turned on by default.

separated by spaces. If you give multiple values, you may need to enclose them in quotes,
depending on the shell you use. Any embedded filenames must be given with absolute paths. Warning:
do not use this form if any of the options has an argument such as a filename that might contain
spaces. In that case, use one or more -vmption options instead. This option will be used when
compiling and running classes. See also -javaoptions.

-X* Non-standard VM Options.

-Xbootclasspath:<path>
Set search path for bootstrap classes and resources

-Xbootclasspath/a:<path>
Append to end of bootstrap class path

Options for running jcov

-XX* | -Xms* | -Xmx*
Non-standard VM Options

Tests Specifying collections of tests.

at-files
Long lists of options and tests may be encapsulated in "at-files". Place the options and/or tests
in a file and specify the name of the file on the command line with @file. Options or tests that
include white space should be enclosed within either single or double quote characters. Comments
may be included in the file by prefixing them with '#'. To specify an option beginning with '@' on
the command line, use "@@" to avoid @file expansion.

Groups A test suite may define named groups of tests. To specify the name of a group of tests on the
command line, use test-suite-dir:group-name, where test-suite-dir is a path to the root directory
of the test suite (i.e the directory containing the TEST.ROOT file), and where group-name is the
name of the group of tests defined in the test suite. If test-suite-dir is omitted it defaults to
the value of the -dir option, if given, or to the current directory otherwise. (Note: on Windows,
to avoid confusion with absolute path names including a drive specifier, the test-suite-dir must
not be specified with a relative path consisting of a single letter.)

Groups are defined in a test suite using one or more Java
properties files. The names of these files must be listed in the "groups" entry in TEST.ROOT. If
the filename is enclosed in square brackets, no error message will be given if the file cannot be
found. Within the property files, each entry specifies items to be included or excluded from the
group. To include a test or directory of tests, simply specify the name of the test or directory.
To exclude a test or directory of tests, use '-' followed by the name of the test or directory. To
include the contents of another group, use ':' followed by the name of the group. There must be no
spaces between the "-" or ":" and the name that follows.
