问题
I tried to run the mathService example presented under:
https://micronaut-projects.github.io/micronaut-test/latest/guide/#junit5
which should explain testing a micronaut service with junit5.
I added
testAnnotationProcessor "io.micronaut:micronaut-inject-java"
testCompile "io.micronaut.test:micronaut-test-junit5:1.1.3"
testCompile "org.mockito:mockito-junit-jupiter:2.22.0"
testRuntime "org.junit.jupiter:junit-jupiter-engine:5.1.0"
to my dependencies.
I coded MathService, MathServiceImpl in src/main/java and MathServiceTest in src/test/java
Syntax check while editing works fine, gradlew build blames
package org.junit.jupiter.params.provider does not exist
package io.micronaut.test.annotation does not exist
what is contrary to editing where the import of these packages works fine.
junit5 Test runs into error message:
org.junit.jupiter.engine.execution.ConditionEvaluationException: Failed to evaluate condition [io.micronaut.test.extensions.junit5.MicronautJunit5Extension]: @MicronautTest used on test but no bean definition for the test present. This error indicates a misconfigured build or IDE. Please add the 'micronaut-inject-java' annotation processor to your test processor path (for Java this is the testAnnotationProcessor scope, for Kotlin kaptTest and for Groovy testCompile). See the documentation for reference: https://micronaut-projects.github.io/micronaut-test/latest/guide/

this error messgae contains the link
https://micronaut-projects.github.io/micronaut-test/latest/guide/
which is exactly where I came from.
Can somene give me some more useful information how to test a micronaut service with junit5 ?
