== test-app



=== Purpose


Runs all Grails unit and integration tests and generates reports. The command returns appropriate response codes for embedding with continuous integration servers.


=== Examples


[source,groovy]
----
grails test-app
grails test-app Foo
grails test-app Foo Bar
----


=== Description


Usage:
[source,groovy]
----
grails <<environment>>* test-app <<names>>* [-unit|-integration]
----

Fired Events:


Executes the Grails unit and integration tests located in the `src/test/groovy` and `src/integration-test/groovy` directories. By default all tests are executed, but you can specify the names of the tests (without the "Tests" or other test type suffix) as argument to the command:

[source,groovy]
----
grails test-app *Foo*
grails test-app *Foo* *Bar*
----

The first example will execute a test called `FooSpec.groovy` whilst the second will execute `FooSpec.groovy` and `BarSpec.groovy` if they exist.

The task of finding tests that match the pattern you provide is passed to Gradle. Take a look at the section in their docs titled link:https://docs.gradle.org/current/userguide/java_plugin.html#test_filtering[Test filtering] for more information.

You can also choose to only run the unit or integration tests:

[source,groovy]
----
grails test-app -unit
grails test-app -integration
----

If you only wish to re-run failed tests use the -rerun flag

[source,groovy]
----
grails test-app -rerun
----

See the link:{guidePath}testing.html[Testing] section for examples on how to combine the different options to target tests.
