Spring-boot utilizes Spring profiles which allow for instance to have separate config for different environments. One way I use this feature is to configure test database to be used by integration tests. I wonder however is it necessary to create my own profile 'test' and explicitly activate this profile in each test file? Right now I do it in the following way:
Create application-test.properties inside src/main/resources Write test specific config there (just the database name for now) In every test file include: @ActiveProfiles("test")
Is there a smarter / more concise way? For instance a default test profile?
Edit 1: This question pertains to Spring-Boot 1.4.1
As far as I know there is nothing directly addressing your request - but I can suggest a proposal that could help:
You could use your own test annotation that is a meta annotation comprising @SpringBootTest
and @ActiveProfiles("test")
. So you still need the dedicated profile but avoid scattering the profile definition across all your test.
This annotation will default to the profile test
and you can override the profile using the meta annotation.
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@SpringBootTest
@ActiveProfiles
public @interface MyApplicationTest {
@AliasFor(annotation = ActiveProfiles.class, attribute = "profiles") String[] activeProfiles() default {"test"};
}
Another way to do this is to define a base (abstract) test class that your actual test classes will extend :
@RunWith(SpringRunner.class)
@SpringBootTest()
@ActiveProfiles("staging")
public abstract class BaseIntegrationTest {
}
Concrete test :
public class SampleSearchServiceTest extends BaseIntegrationTest{
@Inject
private SampleSearchService service;
@Test
public void shouldInjectService(){
assertThat(this.service).isNotNull();
}
}
This allows you to extract more than just the @ActiveProfiles
annotation. You could also imagine more specialised base classes for different kinds of integration tests, e.g. data access layer vs service layer, or for functional specialties (common @Before
or @After
methods etc).
You could put an application.properties file in your test/resources folder. There you set
spring.profiles.active=test
This is kind of a default test profile while running tests.
src/test/resources/application.properties
file, src/main/resources/application.properties
content is ignored when running tests.
application-test.properties
for tests and override only the properties you need.
spring.profiles.active=test
like the answer says.
There are two approaches.
Load from config/
(2022 update, tested against Spring Boot 2.6)
Along with the approach below, you can also add config to src/test/resources/config/application.yml
src/
├── main/
│ ├── java/
│ │ └── ...
│ └── resources/
│ └── application.yml <- default properties, always loaded
└── test/
├── java/
│ └── ...
└── resources/
└── config/
└── application.yml <- test properties, will override the defaults
Spring Boot will automatically find and load application.properties and application.yaml files from the following locations when your application starts: From the classpath The classpath root The classpath /config package From the current directory The current directory The /config subdirectory in the current directory Immediate child directories of the /config subdirectory The list is ordered by precedence (with values from lower items overriding earlier ones). Documents from the loaded files are added as PropertySources to the Spring Environment.
Manual import using spring.config.import
(original answer from 2021, tested against Spring Boot 2.4)
One solution is to have 3 properties files and to import
src/main/resources/application.yml - contains the application's default props
src/test/resources/application.yml - sets the profile to 'test', and imports properties from 'main'
src/test/resources/application-test.yml - contains test-specific profiles, which will override 'main'
Here is the content of src/test/resources/application.yml
:
# for testing, set default profile to 'test'
spring.profiles.active: "test"
# and import the 'main' properties
spring.config.import: file:src/main/resources/application.yml
For example, if src/main/resources/application.yml
has the content
ip-address: "10.7.0.1"
username: admin
and src/test/resources/application-test.yml
has
ip-address: "999.999.999.999"
run-integration-test: true
Then (assuming there are no other profiles)...
when running tests,
profiles=test
--
ip-address=999.999.999.999
username=admin
run-integration-test=true
and when running the application normally
profiles=none
--
ip-address=10.7.0.1
username=admin
run-integration-test <undefined>
Note: if src/main/resources/application.yml
contains spring.profiles.active: "dev"
, then this won't be overwritten by src/test/resources/application-test.yml
src/test/resources/application.yml
file, environment.getActiveProfiles()
will still return the correct test profile but if I get the active profile via @Value("${spring.profiles.active:}")
annotation, it will be null.
A delarative way to do that (In fact, a minor tweek to @Compito's original answer):
Set spring.profiles.active=test in test/resources/application-default.properties. Add test/resources/application-test.properties for tests and override only the properties you need.
application.properties
in the classpath gets parsed too, then the test/resources/application-default.properties
and then, because the profile "test" is detected, the test/resources/application-test.properties
gets parsed? Otherwise it would not solve @ciastek's issue as commented under @Compito's answer.
You can put your test specific properties into src/test/resources/config/application.properties
.
The properties defined in this file will override those defined in src/main/resources/application.properties
during testing.
For more information on why this works have a look at Spring Boots docs.
If you use maven, you can add this in pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<configuration>
<argLine>-Dspring.profiles.active=test</argLine>
</configuration>
</plugin>
...
Then, maven should run your integration tests (*IT.java) using this arugument, and also IntelliJ will start with this profile activated - so you can then specify all properties inside
application-test.yml
and you should not need "-default" properties.
To activate "test" profile write in your build.gradle:
test.doFirst {
systemProperty 'spring.profiles.active', 'test'
activeProfiles = 'test'
}
In my case I have different application.properties depending on the environment, something like:
application.properties (base file)
application-dev.properties
application-qa.properties
application-prod.properties
and application.properties contains a property spring.profiles.active to pick the proper file.
For my integration tests, I created a new application-test.properties
file inside test/resources
and with the @TestPropertySource({ "/application-test.properties" })
annotation this is the file who is in charge of picking the application.properties I want depending on my needs for those tests
@ActiveProfiles
, not @TestPropertySource
.
Another programatically way to do that:
import static org.springframework.core.env.AbstractEnvironment.DEFAULT_PROFILES_PROPERTY_NAME;
@BeforeClass
public static void setupTest() {
System.setProperty(DEFAULT_PROFILES_PROPERTY_NAME, "test");
}
It works great.
If you simply want to set/use default profile at the time of making build through maven then, pass the argument -Dspring.profiles.active=test
Just like
mvn clean install -Dspring.profiles.active=dev
I've usually done a base class for all integration tests with common code and annotations. Do not forget make it abstract
in order not to instatiate. E.g:
@SpringBootTest
@Transactional
@AutoConfigureMockMvc
@ActiveProfiles("test")
public abstract class AbstractControllerTest {
@Autowired
protected MockMvc mockMvc;
protected ResultActions perform(MockHttpServletRequestBuilder builder) throws Exception {
return mockMvc.perform(builder);
}
}
// All annotations are inherited
class AccountControllerTest extends AbstractControllerTest {
....
The best solution I have found is the last suggestion here: https://inspeerity.com/blog/setting-default-spring-profile-for-tests-with-override-option/ The author also desribes the problem very clearly and discusses the downside of every other approach I can think of.
Create a file application-default.properties
in your test resources, containing a single line:
spring.profiles.active=test
This takes advantage of the fact that Spring automatically enables a "default" profile if no other profiles were explicitly set. Now, your application-test.properties
file will be used by default, for all tests.
Add spring.profiles.active=tests
in your application.properties file, you can add multiple properties file in your spring boot application like application-stage.properties
, application-prod.properties
, etc. And you can specify in your application.properties file while file to refer by adding spring.profiles.active=stage
or spring.profiles.active=prod
you can also pass the profile at the time running the spring boot application by providing the command:
java -jar
-Dspring.profiles.active=local
build/libs/turtle-rnr-0.0.1-SNAPSHOT.jar
According to the profile name the properties file is picked up, in the above case passing profile local
consider the application-local.properties
file
