Spring boot does not allow custom properties from application.properties during integration tests

My Spring test boot file configuration is as follows:

@RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = {TestEnd2EndIntegrationConfiguration.class}) @WebAppConfiguration @ActiveProfiles(Profiles.TEST)//=="test" @Transactional public abstract class AbstractEnd2EndIntegrationTest { }

Then from application-test.properties I have the following custom properties:

 database.hibernate.dialect=org.hibernate.dialect.H2Dialect database.hibernate.hbm2ddl.auto=create database.hibernate.logSqlInfo=true

What I use as follows:

 @Value("${database.hibernate.dialect}") private String hibernateDialect;

However, custom properties are not allowed, and I get exceptions, such as:

 com.bignibou.it.controller.signup.SignupRestControllerTest > shouldRejectUnavailableEmailAddress FAILED java.lang.IllegalStateException Caused by: org.springframework.beans.factory.BeanCreationException Caused by: org.hibernate.boot.registry.selector.spi.StrategySelectionException

Here is my gradle configuration:

  sourceSets { main { output.resourcesDir = output.classesDir } integrationTest { java.srcDirs = ['src/it/java'] resources.srcDirs = ['src/it/resources', 'src/main/resources'] compileClasspath = sourceSets.main.output + configurations.testRuntime runtimeClasspath = output + compileClasspath } } task integrationTest(type: Test) { description "Run the integration tests." testClassesDir = sourceSets.integrationTest.output.classesDir classpath = sourceSets.integrationTest.runtimeClasspath reports.html.destination = file("$reports.html.destination/integration") reports.junitXml.destination = file("$reports.junitXml.destination/integration") }

When I run tests from the IDE (intellij), I get another error:

Here is the detailed reason from gradle integrationTest

It can be seen that the properties are not expanded ... Why is this?

In fact, the problem was the following line of code:

 @SpringApplicationConfiguration(classes = {TestEnd2EndIntegrationConfiguration.class})

TestEnd2EndIntegrationConfiguration not a Spring boot application with the main one and, most importantly, it is not annotated with the @EnableAutoConfiguration annotation.

I changed to:

 @Configuration @EnableAutoConfiguration(exclude = { ManagementWebSecurityAutoConfiguration.class, ... MailSenderAutoConfiguration.class }) @ComponentScan(basePackages = {"com.bignibou.configuration", "com.bignibou.it.configuration"}) public class TestApplication { public static void main(String[] args) throws Exception { SpringApplication.run(TestApplication.class, args); } }

and my abstract test class:

 @RunWith(SpringJUnit4ClassRunner.class) @SpringApplicationConfiguration(classes = {TestApplication.class})//Notice the change @WebAppConfiguration @ActiveProfiles(Profiles.TEST) @Transactional public abstract class AbstractIntegrationTest { }

Tests now run as a Spring boot application, and custom properties in application.properties also allowed.

You need 3 things so that your properties are automatically added to your integration test classes:

  • PropertySource Annotations. It seems like you are missing it. You can add something like this to your abstract integration test class:
 @PropertySource(value= {"classpath:*.properties"})
  1. The properties file should be in your classpath. I recommend adding a separate folder for test and test test properties. Create the integration-test-resources directory in src/main and copy your properties files there, and then configure the build manager to add them as class resources.

Here is an example of how to do this in Gradle:

 sourceSets { integrationTest { resources { srcDir "integration-test-resources" } } }
  1. Annotate your property with @Value . It looks like you are already doing this.

I believe that you should use spring.jpa.hibernate.dll-auto if you want to put your Hibernate properties in the application-${profile}.properties properties file application-${profile}.properties , i.e. Spring

In addition, you should use spring.jpa.database-platform=org.hibernate.dialect.H2Dialect .

I use Spring Boot with this configuration, and I never needed any @PropertySource annotations.
