### Question:
DMNImportTypesHelperImpl implements DMNImportTypesHelper { @Override public boolean isPMML(final Path path) { return matchesExtension(path, DMNImportTypes.PMML); }  @Override boolean isDMN(final Path path); @Override boolean isPMML(final Path path); @Override boolean isJava(final Path path);  }### Answer:
@Test public void testIsPMML() { assertThat(helper.isPMML(dmnPath)).isFalse(); assertThat(helper.isPMML(pmmlPath)).isTrue(); assertThat(helper.isPMML(javaPath)).isFalse(); }
