*Target Audience:* Those interested in running the testsuite or a subset
thereof, with various configuration options.

[[running-the-testsuite]]
== Running the testsuite

The tests can be run using:

* `build.sh` or `build.bat`, as a part of WildFly build.
** By default, only smoke tests are run. To run all tests, run build.sh
install -DallTests.
* `integration-tests.sh` or `integration-tests.bat`, a convenience
script which uses bundled Maven (currently 3.0.3), and runs all parent
testsuite modules (which configure the AS server).
* pure maven run, using `mvn install`.

The scripts are wrappers around Maven-based build. Their arguments are
passed to Maven (with few exceptions described below). This means you
can use:

* build.sh (defaults to install)
* build.sh install
* build.sh clean install
* integration-tests.sh install
* ...etc.

[[supported-maven-phases]]
=== Supported Maven phases

Testsuite actions are bounds to various Maven phases up to `verify`.
Running the build with earlier ﻿phases may fail in the submodules due to
missed configuration steps. Therefore, the only Maven phases you may
safely run, are:

* clean
* install
* site

The `test` phase is not recommended to be used for scripted jobs as we
are planning to switch to the `failsafe` plugin bound to the
`integration-test` and `verify` phases. See
https://issues.redhat.com/browse/WFLY-625[WFLY-625] and
https://issues.redhat.com/browse/WFLY-228[WFLY-228].

[[test-groups]]
=== Test groups

To define groups of tests to be run, these properties are available:

* `-DallTests` - Runs all subgroups.
* `-DallInteg` - Runs all integration tests. Same as
`cd testsuite/integration; mvn clean install -DallTests`
* `-Dts.integ` - Basic integration + clustering tests.
* `-Dts.clustering` - Clustering tests.
* `-Dts.iiop` - IIOP tests.
* `-Dts.multinode `- Tests with many nodes.
* `-Dts.manualmode` - Tests with manual mode Arquillian containers.
* `-Dts.bench` - Benchmark tests.
* `-Dts.stress` - Stress tests.
* `-Dts.domain` - Domain mode tests.
* `-Dts.compat` - Compatibility tests.

[[examples]]
== Examples

* `integration-tests.sh [install] ` `` `-- Runs smoke tests.`
* `integration-tests.sh clean install -- Cleans the target directory, then runs smoke tests.`
* `integration-tests.sh install -Dts.smoke ` `` `-- Same as above.`
* `integration-tests.sh install -DallTests ` ``
`-- Runs all testsuite tests.`
* `integration-tests.sh install -Dts.stress -- Runs smoke tests and stress tests.`
* `integration-tests.sh install -Dts.stress -Dts.noSmoke -- Runs stress tests only.`

*Pure maven* - if you prefer not to use scripts, you may achieve the
same result with:

* `mvn ... -rf testsuite`

The `-rf ...` parameter stands for "resume from" and causes Maven to run
the specified module _and all successive_.

It's possible to run only a single module (provided the ancestor modules
were already run to create the AS copies) :

* `mvn ... -pl testsuite/integration/cluster`

The `-pl ...` parameter stands for "project list" and causes Maven to
run the specified module _only_.

[[output-to-console]]
=== Output to console

[source,java,options="nowrap"]
----
-DtestLogToFile
----

[[other-options]]
=== Other options

`-DnoWebProfile` - Run all tests with the _full_ profile (
`standalone-full.xml`). By default, most tests are run under _web_
profile ( `standalone.xml`).

`-Dts.skipTests` - Skip testsuite's tests. Defaults to the value of
`-DskipTests`, which defaults to `false`. To build AS, skip unit tests
and run testsuite, use `-DskipTests -Dts.skipTests=false`.

[[timeouts]]
=== Timeouts

[[surefire-execution-timeout]]
==== Surefire execution timeout

Unfortunatelly, no math can be done in Maven, so instead of applying a
timeout ratio, you need to specify timeout manually for Surefire.

[source,java,options="nowrap"]
----
-Dsurefire.forked.process.timeout=900
----

[[in-test-timeout-ratios]]
==== In-test timeout ratios

Ratio in prercent - 100 = default, 200 = two times longer timeouts for
given category.

Currently we have five different ratios. Later, it could be replaced
with just one generic, one for database and one for deployment
operations.

[source,java,options="nowrap"]
----
-Dtimeout.ratio.fsio=100
-Dtimeout.ratio.netio=100
-Dtimeout.ratio.memio=100
-Dtimeout.ratio.proc=100
-Dtimeout.ratio.db=100
----

[[running-a-single-test-or-specified-tests]]
=== Running a single test (or specified tests)

Single test is run using *-Dtest=...* . Examples:

* `./integration-tests.sh install` `+-Dtest='*Clustered*'+` `-Dintegration.module` `-Dts.clustering`
* `./integration-tests.sh clean install -Dtest=org` `/` `jboss` `/` `as`
`/` `test` `/` `integration` `/` `ejb/async/*TestCase.java`
`-Dintegration.module` `-Dts.basic`
* `cd testsuite; mvn install` `+-Dtest='*Clustered*'+`
`-Dts.basic`
`# No need for -Dintegration.module - integration module is active by default.`

The same shortcuts listed in "Test groups" may be used to activate the
module and group profile.

Note that `-Dtest=` overrides `<includes>` and `<exludes>` defined in
pom.xml, so do not rely on them when using wildcards - all compiled test
classes matching the wildcard will be run.

*Which Surefire execution is used?*

Due to Surefire's design flaw, tests run multiple times if there are
multiple surefire executions. +
To prevent this, if `-Dtest=`... is specified, non-default executions
are disabled, and standalone-full is used for all tests. +
If you need it other way, you can overcome that need:

* `basic-integration-web.surefire with standalone.xml - Configure standalone.xml to be used as server config.`
* `basic-integration-non-web.surefire - For tests included here, technically nothing changes.`
* `basic-integration-2nd.surefire - Simply run the second test in another invocation of Maven.`

[[running-against-existing-as-copy-not-the-one-from-buildtargetjboss-as-]]
=== Running against existing AS copy (not the one from
build/target/jboss-as-*)

*-Djboss.dist=<path/to/jboss-as>* will tell the testsuite to copy that
AS into submodules to run the tests against.

For example, you might want to run the testsuite against AS located in
`/opt/wildfly-8` :

[source,java,options="nowrap"]
----
./integration-tests.sh -DallTests -Djboss.dist=/opt/wildfly-8
----

The difference between jboss.dist and jboss.home:

jboss.dist is the location of the tested binaries. It gets copied to
testsuite submodules.

jboss.home is internally used and points to those copied AS instances
(for multinode tests, may be even different for each AS started by
Arquillian).

[[running-against-a-running-jboss-as-instance]]
==== Running against a running JBoss AS instance

Arquillian's WildFly {wildflyVersion} container adapter allows specifying
`allowConnectingToRunningServer` in `arquillian.xml`, which makes it
check whether AS is listening at `managementAddress:managementPort`, and
if so, it uses that server instead of launching a new one, and doesn't
shut it down at the end.

All arquillian.xml's in the testsuite specify this parameter. Thus, if
you have a server already running, it will be re-used.

[[running-against-jboss-enterprise-application-platform-eap-6.0]]
==== Running against JBoss Enterprise Application Platform (EAP) 6.0

To run the testsuite against AS included JBoss Enterprise Application
Platform 6.x (EAP), special steps are needed.

Assuming you already have the sources available, and the distributed EAP
maven repository unzipped in e.g. `/opt/jboss/eap6-maven-repo/` :

1) Configure maven in settings.xml to use only the EAP repository. This
repo contains all artifacts necessary for building EAP, including maven
plugins. +
The build (unlike running testsuite) may be done offline. +
The recommended way of configuring is to use special settings.xml, not
your local one (typically in .m2/settings.xml).

[source,xml,options="nowrap"]
----
   <mirror>
      <id>eap6-mirror-setting</id>
      <mirrorOf>
         *,!central-eap6,!central-eap6-plugins,!jboss-public-eap6,!jboss-public-eap6-plugins
      </mirrorOf>
      <name>Mirror Settings for EAP 6 build</name>
      <url>file:///opt/jboss/eap6-maven-repo</url>
    </mirror>
  </mirrors>
----

\2) Build EAP. You won't use the resulting EAP build, though. The
purpose is to get the artifacts which the testsuite depends on.

[source,java,options="nowrap"]
----
mvn clean install -s settings.xml -Dmaven.repo.local=local-repo-eap
----

\3) Run the testsuite. Assuming that EAP is located in `/opt/eap6`, you
would run:

[source,java,options="nowrap"]
----
./integration-tests.sh -DallTests -Djboss.dist=/opt/eap6
----

[[running-with-a-debugger]]

[IMPORTANT]

JBoss AS is started by Arquillian, when the first test which requires
given instance is run. Unless you pass *-DtestLogToFile=false,* *there's
(currently) no challenge text in the console*; it will look like the
first test is stuck. This is being solved in
http://jira.codehaus.org/browse/SUREFIRE-781.

[IMPORTANT]

Depending on which test group(s) you run, multiple AS instances may be
started. In that case, you need to attach the debugger multiple times.

[[running-tests-with-custom-database]]
=== Running tests with custom database

To run with different database, specify the `-Dds` and use these
properties (with the following defaults):

[source,java,options="nowrap"]
----
-Dds.jdbc.driver=
-Dds.jdbc.driver.version=
-Dds.jdbc.url=
-Dds.jdbc.user=test
-Dds.jdbc.pass=test
-Dds.jdbc.driver.jar=${ds.db}-jdbc-driver.jar
----

`driver` is JDBC driver class. JDBC `url`, `user` and `pass` is as
expected.

`driver.version` is used for automated JDBC driver downloading. Users
can set up internal Maven repository hosting JDBC drivers, with
artifacts with

GAV = `jdbcdrivers:${ds.db}:${ds.jdbc.driver.version`}

Internally, JBoss has such repo at
http://nexus.qa.jboss.com:8081/nexus/content/repositories/thirdparty/jdbcdrivers/
.

The `ds.db` value is set depending on ds. E.g. `-Dds=mssql2005` sets
`ds.db=mssql` (since they have the same driver). `-Dds.db` may be
overriden to use different driver.

[line-through]*In case you don't want to use such driver, set just
-Dds.db= (empty) and provide the driver to the AS manually.* +
_Not supported; work in progress on parameter to provide JDBC Driver
jar._

[[default-values]]
==== Default values

For WildFly continuous integration, there are some predefined values for
some of databases, which can be set using:

[source,java,options="nowrap"]
----
-Dds.db=<database-identifier>
----

Where database-identifier is one of: `h2`, `mysql51`

[[running-tests-with-ipv6]]
=== Running tests with IPv6

`-Dipv6` - Runs AS with
`-Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Addresses=true`

and the following defaults, overridable by respective parameter:

[cols=",,,",options="header"]
|=======================================================================
|Parameter |IPv4 default |IPv6 default | 

|-Dnode0 |127.0.0.1 |::1 |Single-node tests.

|-Dnode1 |127.0.0.1 |::1 |Two-node tests (e.g. cluster) use this for the
2nd node.

|-Dmcast |230.0.0.4 |ff01::1 |ff01::1 is IPv6 Node-Local scope mcast
addr.

|-Dmcast.jgroupsDiag |224.0.75.75 |ff01::2 |JGroups diagnostics
multicast address.

|-Dmcast.modcluster |224.0.1.105 |ff01::3 |mod_cluster multicast
address.
|=======================================================================

Values are set in AS configuration XML, replaced in resources (like
ejb-jar.xml) and used in tests.

[[running-tests-with-security-manager-custom-security-policy]]
=== Running tests with security manager / custom security policy

`-Dsecurity.manager` - Run with default policy.

`-Dsecurity.policy=<path>` - Run with the given policy.

`-Dsecurity.manager.other=<set of Java properties>` - Run with the given
properties. Whole set is included in all server startup parameters.

Example:

[source,options="nowrap"]
----
./integration-tests.sh clean install -Dintegration.module -DallTests \
\"-Dsecurity.manager.other=-Djava.security.manager \
-Djava.security.policy==$(pwd)/testsuite/shared/src/main/resources/secman/permitt_all.policy \
-Djava.security.debug=access:failure \"
----

Notice the \" quotes delimiting the whole `-Dsecurity.manager.other`
property.

[[creating-test-reports]]
=== Creating test reports

Test reports are created in the form known from EAP 5. To create them,
simply run the testsuite, which will create Surefire XML files.

Creation of the reports is bound to the `site` Maven phase, so it must
be run separatedly afterwards. Use one of these:

[source,options="nowrap"]
----
./integration-tests.sh site
cd testsuite; mvn site
mvn -pl testsuite site
----

Note that it will take all test results under `testsuite/integration/` -
the pattern is `**/*TestCase.xml`, without need to specify `-DallTests`.

[[creating-coverage-reports]]
=== Creating coverage reports

*Jira:* https://issues.redhat.com/browse/WFLY-585

Coverage reports are created by
http://www.eclemma.org/jacoco/trunk/index.html[JaCoCo].

During the integration tests, Arquillian is passed a JVM argument which
makes it run with JaCoCo agent, which records the executions into
`${basedir}/target/jacoco` .

In the `site` phase, a HTML, XML and CSV reports are generated. That is
done using `jacoco:report` Ant task in `maven-ant-plugin` since JaCoCo's
maven report goal doesn't support getting classes outside
target/classes.

[[usage-integration-testsuite]]
==== Usage

[source,options="nowrap"]
----
./build.sh clean install -DskipTests
./integration-tests.sh clean install -DallTests -Dcoverage
./integration-tests.sh site -DallTests -Dcoverage ## Must run in separatedly.
----

Alternative:

[source,options="nowrap"]
----
mvn clean install -DskipTests
mvn -rf testsuite clean install -DallTests -Dcoverage
mvn -rf testsuite site -DallTests -Dcoverage
----

[[cleaning-the-project]]
=== Cleaning the project

To have most stable build process, it should start with:

* clean target directories
* only central Maven repo configured
* clean local repository or at least:
** free of artefacts to be built
** free of dependencies to be used (especially snapshots)

To use , you may use these commands:

[source,options="nowrap"]
----
mvn clean install -DskipTests -DallTests  ## ...to clean all testsuite modules.
mvn dependency:purge-local-repository build-helper:remove-project-artifact -Dbuildhelper.removeAll
----

In case the build happens in a shared environment (e.g. network disk),
it's recommended to use local repository:

[source,java,options="nowrap"]
----
cp /home/hudson/.m2/settings.xml .
sed "s|<settings>|<settings><localRepository>/home/ozizka/hudson-repos/$JOBNAME</localRepository>|" -i settings.xml
----

Or:

[source,java,options="nowrap"]
----
mvn clean install ... -Dmaven.repo.local=localrepo
----
