Class GuiceyHooksRule

java.lang.Object

org.junit.rules.ExternalResource

ru.vyarus.dropwizard.guice.test.GuiceyHooksRule

All Implemented Interfaces:

org.junit.rules.TestRule

public class GuiceyHooksRule
extends org.junit.rules.ExternalResource

Junit rule for changing application configuration (remove some components or register test specific (e.g. mocks)). Supposed to be used in conjunction with DropwizardAppRule or GuiceyAppRule. Must be used ONLY with RuleChain because normally rules order is not predictable:

 static GuiceyAppRule RULE = new GuiceyAppRule(App.class, null);
    {@literal @}ClassRule
    public static RuleChain chain = RuleChain
            .outerRule(new GuiceyHooksRule((builder) -> builder.modules(...)))
            .around(RULE);
 

To declare common extensions for all tests, declare common rule in test class (without @ClassRule annotation!) and use it in chain:

 public class BaseTest {
         static GuiceyHooksRule BASE = new GuiceyHooksRule((builder) -> builder.modules(...))
     }

     public class SomeTest extends BaseTest {
         static GuiceyAppRule RULE = new GuiceyAppRule(App.class, null);
         {@literal @}ClassRule
         public static RuleChain chain = RuleChain
            .outerRule(BASE)
            .around(new GuiceyHooksRule((builder) -> builder.modules(...)) // optional test-specific staff
            .around(RULE);
     }
 

IMPORTANT: rule will not work with spock extensions (because of lifecycle specifics)! Use UseGuiceyHooks or new hooks attribute in UseGuiceyApp or UseDropwizardApp instead.

Rule is thread safe: it is assumed that rule will be applied at the same thread as test application initialization.
