Auto-configuration is one of the most powerful features of Spring Boot. Tests for auto-configuration classes usually follow the same pattern. Most tests start up an ApplicationContext with the auto-configuration class under test and depending on the test, also load additional configuration to simulate user behavior. The recurrence of this pattern can add a lot of repetition in the code base.

Spring Boot 2.0 provides a suite of new test helpers for easily configuring an ApplicationContext to simulate auto-configuration test scenarios. The following example configures an ApplicationContextRunner to test the UserServiceAutoConfiguration:

Milestone 4 of Spring Boot 2.0 brings important changes to the security auto-configuration provided by Spring Boot.

Problem Statement

Until Spring Boot 1.x, the default auto-configuration secured all of the application endpoints using basic authentication. If actuator was on the classpath, there was a separate security configuration that applied to the actuator endpoints. The way these two auto-configurations would turn on and off was completely independent. Because of this, users wanting to provide custom security found themselves fighting ordering issues with WebSecurityConfigurerAdapters.

The third milestone of Spring Boot 2.0 is available now from the Spring milestone repository. This milestone ensures compatibility with Spring Framework 5.0.0.RC3 and contains a number of other dependency upgrades. This release closes over 100 issues and pull requests, thanks to all that contributed!

For a complete list of changes, and upgrade instructions, see the Spring Boot 2.0.0.M3 Release Notes on the WIKI and the updated reference documentation.
