IntelliJ automatically hides stacktrace elements from the `org.gradle` package, which makes running/debugging tests more difficult. You can disable this behavior by changing IntelliJ Preferences under Editor -> General -> Console. In the "Fold lines that contain" section, remove the `org.gradle` entry.

    Map<K, V> map = new LinkedHashMap<>();
    for (Entry<K, V> entry : entries) {
      map.put(entry.getKey(), entry.getValue());
