#### 3. Clone Test Data

Required for SearchApiTests:

    $ git clone https://github.com/codelibs/fess-testdata.git /tmp/fess-testdata

#### 4. Run Integration Tests

    $ mvn test -P integrationTests -Dtest.fess.url="http://localhost:8080" -Dtest.search_engine.url="http://localhost:9201"

To run a single test case:
