[[WildFly_Testsuite_Overview]]
= WildFly Testsuite Overview

WARNING: This section has not been updated for a long time and some sections are out of date. Contributions are welcome.

This document will detail the implementation of the testsuite
integration submodule as it guides you on adding your own test cases.

The WildFly integration test suite has been designed with the following
goals:

* support execution of all identified test case use cases
* employ a design/organization which is scalable and maintainable
* provide support for the automated measurement of test suite quality
(generation of feature coverage reports, code coverage reports)

In addition, these requirements were considered:

* identifying distinct test case runs of the same test case with a
different set of client side parameters and server side parameters
* separately maintaining server side execution results (e.g. logs, the
original server configuration) for post-execution debugging
* running the testsuite in conjunction with a debugger
* the execution of a single test (for debugging purposes)
* running test cases against different container modes (managed in the
main, but also remote and embedded)
* configuring client and server JVMs separately (e.g., IPv6 testing)

[[test-suite-organization]]
== Test Suite Organization

The testsuite module has a few submodules:

* *benchmark* - holds all benchmark tests intended to assess relative
performance of specific feature
* *domain* - holds all domain management tests
* *integration* - holds all integration tests
* *stress* - holds all stress tests

It is expected that test contributions fit into one of these categories.

The `pom.xml` file located in the testsuite module is inherited by all
submodules and is used to do the following:

* set defaults for common testsuite system properties (which can then be
overridden on the command line)
* define dependencies common to all tests (Arquillian, junit or testng,
and container type)
* provide a workaround for `@Resource(lookup=...)` which requires
libraries in jbossas/endorsed

It should not:

* define module-specific server configuration build steps
* define module-specific surefire executions

These elements should be defined in logical profiles associated with
each logical grouping of tests; e.g., in the pom for the module which
contains the tests. The submodule poms contain additional details of
their function and purpose as well as expanded information as shown in
this document.

[[profiles]]
== Profiles

You should not activate the abovementioned profiles by -P, because that
disables other profiles which are activated by default.

Instead, you should always use activating properties, which are in
parentheses in the lists below.

Testsuite profiles are used to group tests into logical groups.

* all-modules.module.profile (all-modules)
* integration.module.profile (integration.module)
* compat.module.profile (compat.module)
* domain.module.profile (domain.module)
* benchmark.module.profile (benchmark.module)
* stress.module.profile (stress.module)

They also prepare WildFly instances and resources for respective
testsuite submodules.

* jpda.profile - sets surefire.jpda.args (debug)
* ds.profile - sets database properties and prepares the datasource (ds=<db id>)
** Has related database-specific profiles, like mysql51.profile etc.

Integration testsuite profiles configure surefire executions.

* smoke.integration.tests.profile
* basic.integration.tests.profile
* clustering.integration.tests.profile

== Integration tests

[[smoke--dts.smoke--dts.nosmoke]]
=== Smoke `-Dts.smoke`

Contains smoke tests.

Runs by default; use `-Dts.noSmoke` to prevent running.

Tests should execute quickly.

Divided into two Surefire executions:

* One with full platform
* Second with web profile (majority of tests).

[[basic--dts.basic]]
=== Basic `-Dts.basic`

Basic integration tests - those which do not need a special configuration
like cluster.

Divided into three Surefire executions:

* One with full platform,
* Second with web profile (majority of tests).
* Third with web profile, but needs to be run after server restart to
check whether persistent data are really persisted.

[[cluster--dts.clustering]]
=== Clustering `-Dts.clustering`

Contains all tests relating to clustering aspects of the application server, such as:

* web session clustering,
* Jakarta Enterprise Beans session clustering,
* command dispatcher,
* web session affinity handling,
* and other areas.

Tests should leverage shared testing logic by extending `org.jboss.as.test.clustering.cluster.AbstractClusteringTestCase`.
The test case contract is that before executing the test method, all specified servers are started and all specified
deployments are deployed. This allows Arquillian resource injection into the test case.

There are four WildFly server instances, one load-balancer (Undertow) and one datagrid (Infinispan server) available
for the tests.

==== Maven profiles and Parallelization

There are maven profiles that might come in handy for testing:

* `ts.clustering.common.profile` prepares server configurations used by test execution profiles
* `ts.clustering.cluster.ha.profile` runs tests against `standalone-ha.xml` profile
* `ts.clustering.cluster.fullha.profile` runs tests which require `standalone-full-ha.xml` profile; e.g. tests requiring JMS subsystem
* `ts.clustering.cluster.ha-infinispan-server.profile` runs tests against `standalone-ha.xml` profile with Infinispan Server provisioned via `@ClassRule`
* `ts.clustering.single.profile` runs clustering tests that are using a non-HA server profile
* `ts.clustering.byteman.profile` runs clustering tests that require installation of byteman rules

For instance, to only run tests that run against full-ha profile, activate clustering tests with `-Dts.clustering` and exclude
the other profiles with `-P`:

    $ ./integration-tests.sh clean install -Dts.noSmoke -Dts.clustering -P \!ts.clustering.cluster.ha.profile,\!ts.clustering.single.profile,\!ts.clustering.byteman.profile

If the testsuite can be run on multiple runners in parallel, the main execution (which takes the majority of the execution time)
can be split by packages using `-Dts.surefire.clustering.ha.additionalExcludes` property.
This property feeds a regular expression to exclude sub-packages of the `org.jboss.as.test.clustering.cluster` package.
The sub-packages at the time of writing are `affinity`, `cdi`, `dispatcher`, `ejb`, `ejb2`, `group`, `jms`, `jpa`,
`jsf`, `provider`, `registry`, `singleton`, `sso`, `web`, and `xsite`.
For instance, to parallelize testsuite execution on two machines (e.g. when using GitHub actions scripting or alike) the following commands
could be used to split the clustering tests into two executions of similar execution time, the first node can run the first half of the tests in sub-packages, e.g.:

    $ ./integration-tests.sh clean install -Dts.noSmoke -Dts.clustering -P="-ts.clustering.cluster.fullha.profile,-ts.clustering.cluster.ha-infinispan-server.profile,-ts.clustering.byteman.profile,-ts.clustering.single.profile" -Dts.surefire.clustering.ha.additionalExcludes=affinity\|cdi\|dispatcher\|ejb\|ejb2\|group\|jms\|jpa

while another node can concurrently run all the other profiles and the other half of sub-packages:

    $ ./integration-tests.sh clean install -Dts.noSmoke -Dts.clustering -Dts.surefire.clustering.ha.additionalExcludes=jsf\|provider\|registry\|singleton\|sso\|web\|xsite

If the test packages get out of sync with the excludes this will result in a test running multiple times, rather than tests being omitted.

==== Running a single test

To run a single test, specifying `-Dtest=foo` is the standard way to do this. However, this overrides the includes/excludes
section of the surefire maven plugin execution. So, in case of the clustering testsuite, the profile which this test belongs
to, needs to be specified as well. For instance, to run a single test from the 'single' test execution, exclude the other
test profiles:

    $ ./integration-tests.sh clean install -Dts.noSmoke -Dts.clustering -P="-ts.clustering.cluster.ha.profile,-ts.clustering.cluster.fullha.profile,-ts.clustering.cluster.ha-infinispan-server.profile,-ts.clustering.byteman.profile,-ts.clustering.single.profile" -Dtest=org.jboss.as.test.clustering.single.dispatcher.CommandDispatcherTestCase

=== Running Infinispan Server tests against custom distribution

To run the Infinispan Server-based tests against a custom distribution, a custom location can be specified with `-Dinfinispan.server.home.override=/foo/bar`
and `-Dinfinispan.server.profile.override=infinispan-13.0.xml` to use a corresponding server profile.
The distribution is then copied over to the build directories and patched with user credentials.

    $ ./integration-tests.sh clean install -Dts.noSmoke -Dts.clustering -P="-ts.clustering.cluster.ha.profile,-ts.clustering.cluster.fullha.profile,-ts.clustering.single.profile,-ts.clustering.byteman.profile,-ts.clustering.single.profile" -Dinfinispan.server.home.override=/Users/rhusar/Downloads/redhat-datagrid-8.3.0-server

Should it be required, the Infinispan Server driver version can be also overridden by `-Dversion.org.infinispan.server.driver=13.0.0.Dev03`.

==== Skipping clustering tests

To skip execution of all clustering tests use `-Dts.noClustering`.
