Model testsuite
|
|
===============
|
|
|
|
Model testsuite runs tests on raw `KeycloakSessionFactory` which is
|
|
initialized only with those providers that are explicitly enabled
|
|
in a used profile via `keycloak.model.parameters` system property.
|
|
|
|
This allows writing tests and running those in different
|
|
configurations quickly, e.g. once with legacy JPA storage,
|
|
second time with purely new Hot Rod implementation.
|
|
|
|
The valid parameters are names of classes in `org.keycloak.testsuite.model.parameters`
|
|
package, and it is possible to combine those by providing multiple class names
|
|
separated by comma.
|
|
|
|
To simplify matters, common combinations of parameters are defined as maven profiles.
|
|
|
|
|
|
Test coverage
|
|
-------------
|
|
|
|
To see test coverage via jacoco, set `jacoco.skip` property to `false`, e.g.:
|
|
|
|
```
|
|
mvn test -Pjpa -Dtest=ClientModelTest -Djacoco.skip=false
|
|
```
|
|
|
|
Then you can generate the coverage report by using the following command:
|
|
|
|
```
|
|
mvn org.jacoco:jacoco-maven-plugin:0.8.7:report \
|
|
-Djacoco.skip=false -Djacoco.dataFile=target/jacoco.exec
|
|
```
|
|
|
|
The test coverage report is then available from `target/site/jacoco/index.html` file.
|
|
|
|
Profiling
|
|
---------
|
|
|
|
If you have [Async Profiler](https://github.com/jvm-profiling-tools/async-profiler/)
|
|
installed, you can generate flame graphs of the test run for profiling purposes.
|
|
To do so, you set `libasyncProfilerPath` system property to the location of the
|
|
async profiler library:
|
|
|
|
```
|
|
mvn test -Pjpa -Dtest=ClientModelTest \
|
|
-DlibasyncProfilerPath=/usr/local/async-profiler/build/libasyncProfiler.so
|
|
```
|
|
|
|
The results are available in the `target/profile.html` file.
|
|
|
|
Usage of Testcontainers
|
|
-----------------------
|
|
|
|
Some profiles within model tests require running 3rd party software, for
|
|
example, database or Infinispan. For running these we are using
|
|
[Testcontainers](https://www.testcontainers.org/). This may require some
|
|
additional configuration of your container engine.
|
|
|
|
#### Podman settings
|
|
|
|
For more details see the following [Podman guide from Quarkus webpage](https://quarkus.io/guides/podman).
|
|
|
|
Specifically, these steps are required:
|
|
```shell
|
|
# Enable the podman socket with Docker REST API (only needs to be done once)
|
|
systemctl --user enable podman.socket --now
|
|
|
|
# Set the required environment variables (need to be run everytime or added to profile)
|
|
export DOCKER_HOST=unix:///run/user/${UID}/podman/podman.sock
|
|
```
|
|
|
|
Testcontainers are using [ryuk](https://hub.docker.com/r/testcontainers/ryuk)
|
|
to cleanup containers after tests. To make this work with Podman add the
|
|
following line to `~/.testcontainers.properties`
|
|
```shell
|
|
ryuk.container.privileged=true
|
|
```
|
|
Alternatively, disable usage of ryuk (using this may result in stale containers
|
|
still running after tests finish. This is not recommended especially if you are
|
|
executing tests from Intellij IDE as it [may not stop](https://youtrack.jetbrains.com/issue/IDEA-190385)
|
|
the containers created during test run).
|
|
```shell
|
|
export TESTCONTAINERS_RYUK_DISABLED=true #not recommended - see above!
|
|
```
|
|
|
|
#### Docker settings
|
|
|
|
To use Testcontainers with Docker it is necessary to
|
|
[make Docker available for non-root users](https://docs.docker.com/engine/install/linux-postinstall/).
|
|
|
|
Running HotRod tests with external Infinispan
|
|
---------------------------------------------
|
|
|
|
By default, Model tests with `hot-rod` profile spawn a new Infinispan container
|
|
with each test execution. It is also possible, to configure Model tests to
|
|
connect to an external instance of Infinispan. To do so, execute tests with
|
|
the following command:
|
|
```shell
|
|
mvn test -Phot-rod \
|
|
-Dhot-rod.start-container=false \
|
|
-Dhot-rod.connection.host=<host> \
|
|
-Dhot-rod.connection.port=<port> \
|
|
-Dhot-rod.connection.username=<username> \
|
|
-Dhot-rod.connection.password=<password>
|
|
```
