### Question:
FSActionBuilder extends NodeBuilderBaseImpl<FSActionBuilder> implements Builder<FSAction> { public FSActionBuilder clearMkdirs() { attributesBuilder.clearMkdirs(); return this; } FSActionBuilder(final Node action,
                    final ActionAttributesBuilder attributesBuilder); static FSActionBuilder create(); static FSActionBuilder createFromExistingAction(final Node action); FSActionBuilder withNameNode(final String nameNode); FSActionBuilder withJobXml(final String jobXml); FSActionBuilder withoutJobXml(final String jobXml); FSActionBuilder clearJobXmls(); FSActionBuilder withConfigProperty(final String key, final String value); FSActionBuilder withDelete(final Delete delete); FSActionBuilder withoutDelete(final Delete delete); FSActionBuilder clearDeletes(); FSActionBuilder withMkdir(final Mkdir mkdir); FSActionBuilder withoutMkdir(final Mkdir mkdir); FSActionBuilder clearMkdirs(); FSActionBuilder withMove(final Move move); FSActionBuilder withoutMove(final Move move); FSActionBuilder clearMoves(); FSActionBuilder withChmod(final Chmod chmod); FSActionBuilder withoutChmod(final Chmod chmod); FSActionBuilder clearChmods(); FSActionBuilder withTouchz(final Touchz touchz); FSActionBuilder withoutTouchz(final Touchz touchz); FSActionBuilder clearTouchzs(); FSActionBuilder withChgrp(final Chgrp chgrp); FSActionBuilder withoutChgrp(final Chgrp chgrp); FSActionBuilder clearChgrps(); @Override FSAction build();  }### Answer:
@Test public void testClearMkdirs() { final FSActionBuilder builder = getBuilderInstance(); for (final Mkdir mkdir : MKDIRS) { builder.withMkdir(mkdir); } builder.clearMkdirs(); final FSAction fsAction = builder.build(); assertTrue(fsAction.getMkdirs().isEmpty()); }
