InteractionObjectTestBuilder is a non-test file under the test directory. Test utilities should be in a testing directory under main, not test, or be in the dedicated testing module.

This issue can be resolved by moving this file to package org.oppia.android.app.player.state.testing.

• All usages must have the imports updated(automatically done by Android Studio).
• Ktlint formatting check java -jar ../oppia-android-tools/ktlint -F --android domain/src/**/*.kt utility/src/**/*.kt data/src/**/*.kt app/src/**/*.kt testing/src/**/*.kt scripts/src/**/*.kt instrumentation/src/**/*.kt should be run to ensure unused imports are removed, and imports are ordered correctly.
• Tests using this util should build correctly in Bazel.
