It brings code coverage analysis directly into the Eclipse workbench.
Installation:
(Marketplace Client) https://marketplace.eclipse.org/content/eclemma-java-code-coverage
(Update Site) https://update.eclemma.org
Usage:
Verified w/ Spring Tool Suite 4.8 and 4.15
& w/ Eclipse 4.5
From the new icon "Coverage", execute:
Coverage As > JUnit Test
it will change to green color the code lines with coverage.
Nota: It applies over the selected item (a method, a class, all the project)
The new tab 'Coverage' indicates the coverage by packages and classes.
Override Spring Boot 3 default JUnit 5 by JUnit 6:
<properties>
<junit-jupiter.version>6.0.0</junit-jupiter.version>
<junit-platform.version>6.0.0</junit-platform.version>
<junit-vintage.version>6.0.0</junit-vintage.version>
</properties>
Tested with Spring Boot 2.4.3:
<!-- imports both Spring Boot test modules as well has JUnit, AssertJ, Hamcrest and other useful libraries -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>

<!-- (at)WithMockUser, etc. -->

<artifactId>spring-security-test</artifactId>
<scope>test</scope>

Import for JUnit 5 asserts:
import static org.junit.jupiter.api.Assertions.*;
assertThrows sample:
@Test
void getAppkvNoRecordExpected() {
this.securityContextWithSuper();
UUID uuid = UUID.randomUUID();
Assertions.assertThrows(NotFoundAppException.class, () -> {
this.techController.getAppkv("Bearer jwt27", "en", uuid,
AppKV.KEY_DAILY_NIGHT_PROCESS_LAST_STACKTRACE);
});
}
assertDoesNotThrow sample:
assertDoesNotThrow( () -> this.myService.myMethod(myArgument) );
Note: See also @WithSecurityContext, @WithUserDetails, @WithAnonynousUser at
import org.springframework.security.test.context.support.WithMockUser;
@Test
@WithMockUser(authorities = { "ROLE_ADMIN" })
void getCalendartfShiftBbcRecordingsUrlsTest() {
//whatever
}
@ParameterizedTest
@ValueSource(ints = {1, 3, 5, -3, 15, Integer.MAX_VALUE}) // six numbers
void isOdd_ShouldReturnTrueForOddNumbers(int number) {
assertTrue(Numbers.isOdd(number));
