Gradle Changes

The build.gradle file includes the library for JUnit5 parameterized tests:

dependencies {
    // Use JUnit Jupiter API for testing.
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.2', 'org.hamcrest:hamcrest:2.2', 'org.junit.jupiter:junit-jupiter-params'

    // Use JUnit Jupiter Engine for testing.
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine'

    // This dependency is used by the application.
    implementation 'com.google.guava:guava:29.0-jre'
}
