+## Test Clojure applications
+
+This example will guide you how to run tests in your Clojure application.
+
+You can checkout the example [source](https://gitlab.com/dzaporozhets/clojure-web-application) and check [CI status](https://ci.gitlab.com/projects/6306).
+
+### Configure project
+
+This is what the `.gitlab-ci.yml` file looks like for this project:
+
+```yaml
+variables:
+  POSTGRES_DB: sample-test
+  DATABASE_URL: "postgresql://postgres@postgres:5432/sample-test"
+
+before_script:
+  - apt-get update -y
+  - apt-get install default-jre postgresql-client -y
+  - wget https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
+  - chmod a+x lein
+  - export LEIN_ROOT=1
+  - PATH=$PATH:.
+  - lein deps
+  - lein migratus migrate
+
+test: 
+  script: 
+    - lein test
+```
+
+In before script we install JRE and [Leiningen](http://leiningen.org/). 
+Sample project uses [migratus](https://github.com/yogthos/migratus) library to manage database migrations. 
+So we added database migration as last step of `before_script` section
+
+You can use public runners available on `gitlab.com` for testing your application with such configuration.
