Maven failsafe recognizes integration test class but not tests in class

Question

I have a multi-module Maven project and I'm trying to setup integration testing tooling with the failsafe plugin.

I added the following to the project's parent pom.xml:

<profiles>
    <profile>
        <id>failsafe</id>
        <build>
            <plugins>
                <plugin>
                    <artifactId>maven-failsafe-plugin</artifactId>
                    <version>2.22.0</version>
                    <executions>
                        <execution>
                            <goals>
                                <goal>integration-test</goal>
                                <goal>verify</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>

I also added that exact same snippet to the child module's pom.xml where the initial tests were added along with this snippet:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Here is the directory structure of the module where the initial integration test has been added:

parent
-aws-service-utils
--src
---main
----java
-----com
------lorem
-------ipsum
--------S3
---------S3.java (dummy class)
---test (in same directory as main)
----java
-----com
------lorem
-------ipsum
--------dolor
---------tests
----------S3IT.java (test class for dummy class)

Here's what S3.java looks like, excluding the imported packages:

public class S3 {
   public int confirmAdd() {
      int sum = 2 + 2;
      return sum;
   }
}

Here's what S3IT.java looks like, again excluding imported packages:

public class S3IT {
  @Test
  public void confirmAdd() {
     int sum = 2+2;
     assertTrue(sum == 4);
  }
}

I run mvn verify -Pfailsafe followed by mvn failsafe:integration-test and get no test output for all of the other classes, as expected. Then the following comes up for the aws-service-utils module:

So it appears to be recognizing the integration test class S3IT.java but not the test inside. I went through the proposed solutions in a similar Stack Overflow post and none of them worked. My primary resource for setting up integration tests with Maven can be found here.
