How to run kotlin test files with mvn test?

Question

I want to run multiple kotlin test files in multiple folders within src/test/kotlin. The problem is when I run mvn test then some tests are running but not all of them. I tried different solutions like adding kotlin-maven-plugin and adding source directory to pom.xml. I also added regExp to recognize all tests. How can I run mvn test so all kotlin tests will be recognized?

Also I use Junit jupiter api therefore this dependency.

import org.junit.jupiter.api.Test  

to all test files and added annotation @Test

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-api</artifactId>
    <scope>test</scope>
</dependency>

This was my solution. I don't have Java in the project.

<build>
        <sourceDirectory>${project.basedir}/src/main/kotlin</sourceDirectory>
        <testSourceDirectory>${project.basedir}/src/test/kotlin</testSourceDirectory>
        <plugins>
            <plugin>
                <artifactId>kotlin-maven-plugin</artifactId>
                <groupId>org.jetbrains.kotlin</groupId>
                <version>${kotlin.version}</version>
                <executions>
                    <execution>
                        <id>compile</id>
                        <goals>
                            <goal>compile</goal>
                        </goals>
                    </execution>

                    <execution>
                        <id>test-compile</id>
                        <goals>
                            <goal>test-compile</goal>
                        </goals>
                        <configuration>
                            <sourceDirs>
                                <sourceDir>${project.basedir}/src/test/kotlin</sourceDir>
                            </sourceDirs>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>3.0.0-M3</version>
                <configuration>
                    <includes>
                        <include>Test*</include>
                        <include>*Test</include>
                        <include>*TestCase</include>
                    </includes>
                </configuration>
            </plugin>
...
</build>

I tried to run mvn test, but only few passed. Even the files that recognize few tests, have more tests.

You seem to be doing everything correctly. Does your IDE run the tests at the method/class/package level? Yes, this is a different execution method, but it might help you highlight where the problem comes from.

I assume you have no @Disabled kind of annotations.

My Maven config for a small project follows - note how I don't have surefire nor any of the filters you have, and I too am using the org.junit.jupiter.api.Test annotation on the tests.
