Test your application

In order to write integration tests for your application, you need ability to spin up a geode cluster from your test and then run tests for your application that work against the cluster. Geode now ships with a JUnit Rule to help.

You can this GfshRule like so:

public class LibraryTest {
    @Rule
    public GfshRule gfshRule = new GfshRule();

    @Test
    public void testSomeLibraryMethod() {
        Library classUnderTest = new Library();
        GfshScript.of("start locator --name=loc",
            "start server --name=serv1",
            "create region --name=test --type=REPLICATE").execute(gfshRule);
        classUnderTest.doPut();
        assertEquals("one", classUnderTest.doGet());
    }
}

Step-by-step guide

You need to follow the following steps to get this to work:

1. Specify geode-junit as a compile dependency for your tests by adding the following in your build.gradle

   testCompile 'org.apache.geode:geode-junit:geodeVersion'

    

2. Specify the gradle plugin that will download and install the Geode distribution to be used by GfshRule by adding the following to your build.gradle file 
   

   apply plugin: 'geode-integration-test-gradle-plugin'

    

3. Write your integration tests by spinning up a Geode cluster using gfsh commands as shown above.
