I have a #Service class where i'm caching some table data. I don't want those queries to run while building mvn install. Is there a way to ignore the file while building and it only execute when i start the server ?
It's a spring-boot application.
Here is background of my issue. I have initialized the spring boot app from http://start.spring.io/ site, which actually adds dummy application test file with SpringBootTest annotation and default contextLoads() with Test annotation, with an intention to initialize and execute all test cases, which needs to initialize and execute all code base. In my opinion this is not required, as we can have respective Test classes per controller/manager, which will give more controlled environment to hook up your Test setups and executions.
I have removed the default application Test file and included respective test classes for code coverage and quality. This way my beans are not executed at server startup time rather build time.

I've just installed Cypress to run e2e tests and that requires my Spring Boot app running so it can plug into the browser to run tests.
I already have an application.properties file under test/resources which creates an H2 memory database populated from a test/resources/data.sql to run my unit and integration tests.
I want to start my app using those test resources so I can run Cypress tests with my testing environment, is that poosible?
I tried changing SPRING_PROFILES_ACTIVE env variable to test but it doesn't take my config files under the test folder, what can I do?
test/resources/application.properties is, as far as I understand it, purely for use in (unit/integration/service) tests that live in test/.
Try creating an additional application-test.properties file in main/resources. This should be used when you have the test Spring profile activated (although it might be better to choose another name for the profile to avoid confusion).
Say I have 10 spring boot test class (annotated with #RunWith(SpringRunner.class) and #SpringBootTest)
Each test needs to launch spring container for like 10 seconds, although the container might do the same init.
So I may need 100 seconds for "mvn test".
Is there a way I can group my 10 test class into 1 suite, and let the container only start once.
So I can:
Only run the suite for "mvn test". (with proper naming for individual test class)
Optionally run individual test in IDE.
Spring uses Cache Management to cache the Application Context between tests:
By default, once loaded, the configured ApplicationContext is reused for each test. Thus, the setup cost is incurred only once per test suite, and subsequent test execution is much faster. In this context, the term “test suite” means all tests run in the same JVM — for example, all tests run from an Ant, Maven, or Gradle build for a given project or module. In the unlikely case that a test corrupts the application context and requires reloading (for example, by modifying a bean definition or the state of an application object) the TestContext framework can be configured to reload the configuration and rebuild the application context before executing the next test. (https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/testing.html#integration-testing)
So this mechanism tries to execute your integration tests on an already running Application Context if possible. As you see multiple Application Context launches, this indicates your tests somehow use a different setup e.g. different profiles active, test properties, MockBeans etc.
The Spring documentation provides an overview on which indicators it puts an Application Context in its cache: https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/testing.html#testcontext-ctx-management-caching
If you e.g. don't change any test property for your integration tests, Spring can run all of them on only one Application Context and be extremely efficient.
Another indicator for your current behaviour might be the use of #DirtiesContext which leads to a fresh Application Context after your test executes.
I was reading through the guide for using Spring Boot Test and there was a paragraph that got me confused.
“As our profiles get richer, it's tempting to swap every now and then in our integration tests. There are convenient tools to do so, like #ActiveProfiles. However, every time we pull a test with a new profile, a new ApplicationContext gets created.”
https://www.baeldung.com/spring-tests
So it assumes that if all tests are run under the same profile, there is only one ApplicationContext created — but how is it possible? I thought that all the objects are recreated for each test suite anyway. Am I missing something?
The official reference says that it's cached.
https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/testing.html#testing-ctx-management
But how does it get loaded into the JUnit runner or Spock one across multiple test suites?
What was missing in my understanding is the fact that all the test suites are run as a part of a single program, so it's easy to cache any objects that are required by all of them, including Spring context.
I've written some test-cases inside a single TestNG Test which extends AbstractTestNGSpringContextTests. The ApplicationContext is correctly setup and I can use it inside my test-cases.
The problem is that the setting up of the applicationContext can take some time and I don't want to do this for every test-class I have, as this would take some time which is unnecessary from my point of view.
So my question is: Is it possible to run more than one TestNG test-class using the same Spring ApplicationContext which is setup only once?
Thanks and best regards,

How about using a #BeforeSuite?
Spring may cache and re-use ApplicationContext when you use similar locations in #ContextConfiguration annotations. See related article from Tomasz Nurkiewicz (#tomasz-nurkiewicz) at http://nurkiewicz.blogspot.com/2010/12/speeding-up-spring-integration-tests.html
Once the TestContext framework loads an ApplicationContext (or WebApplicationContext) for a test, that context will be cached and reused for all subsequent tests that declare the same unique context configuration within the same test suite.
The Spring TestContext framework stores application contexts in a static cache. This means that the context is literally stored in a static variable. In other words, if tests execute in separate processes the static cache will be cleared between each test execution, and this will effectively disable the caching mechanism.
To benefit from the caching mechanism, all tests must run within the same process or test suite. This can be achieved by executing all tests as a group within an IDE. Similarly, when executing tests with a build framework such as Ant, Maven, or Gradle it is important to make sure that the build framework does not fork between tests. For example, if the forkMode for the Maven Surefire plug-in is set to always or pertest, the TestContext framework will not be able to cache application contexts between test classes and the build process will run significantly slower as a result.
I have a set of integration JUnit test cases that I want to run under 2 or more separate spring application contexts. Application contexts differ in configuration settings and bean wirings. However, if I specify the application context file name using the #ContextConfiguration annotation at the top of the JUnit classes then I am only able to run these test cases once for the specified application context. Is it possible to run the same JUnit test cases with different application contexts?
Also, I am interested to execute the test cases once for each application context in the same test run - mvn test.
Put your test code in an abstract class and use subclasses with different #ContextConfigurations. See http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/testing.html#testing-examples-petclinic
You can use a master test application context file that just includes a specific context file by using Maven resource filtering
e.g.
#ContextConfiguration("classpath:test-context.xml")
where src/main/resources/test-context.xml is:
<beans>
<import resource="${project.test.context}" />
</beans>
Then run mvn test -Dproject.test.context=context1.xml, mvn test -Dproject.test.context=context2.xml etc.
If you do that, you should also set a default maven property project.test.context in your POM.
By the way, if these are integration tests, they should by convention be called ...IT.java rather than ...Test.java, and should be run by failsafe (using mvn verify), not surefire.
