+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.
