Micronaut Test
This project provides testing extension for JUnit 5, Spock and Kotest to make it easier to test Micronaut applications.
For more information see the Latest or Snapshot Documentation.
Example Spock Test:
import io.micronaut.test.annotation.MicronautTest
import spock.lang.*
import jakarta.inject.Inject
@MicronautTest // Declares the test as a micronaut test
class MathServiceSpec extends Specification {
@Inject
MathService mathService // Dependency injection is used to supply the system under test
@Unroll
void "should compute #num times 4"() { // This is the test case. #num will be replaces by the values defined in the where: block
when:
def result = mathService.compute(num)
then:
result == expected
where:
num | expected
2 | 8
3 | 12
}
}
Example JUnit 5 Test:
import io.micronaut.test.annotation.MicronautTest;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;
import jakarta.inject.Inject;
@MicronautTest // Declares the test as a micronaut test
class MathServiceTest {
@Inject
MathService mathService; // Dependency injection is used to supply the system under test
@ParameterizedTest
@CsvSource({"2,8", "3,12"})
void testComputeNumToSquare(Integer num, Integer square) {
final Integer result = mathService.compute(num); // Injected bean can be used in test case
Assertions.assertEquals(
square,
result
);
}
}
Snapshots and Releases
Snaphots are automatically published to JFrog OSS using Github Actions.
See the documentation in the Micronaut Docs for how to configure your build to use snapshots.
Releases are published to JCenter and Maven Central via Github Actions.
A release is performed with the following steps:
- Update the draft release.
- Monitor the Workflow to check it passed successfully.
- Celebrate!
