### Question:
SortRowsMeta extends BaseStepMeta implements StepMetaInterface, Serializable { int getDefaultCollationStrength() { return getDefaultCollationStrength( Locale.getDefault() ); } SortRowsMeta(); boolean[] getAscending(); void setAscending( boolean[] ascending ); String getDirectory(); void setDirectory( String directory ); String[] getFieldName(); void setFieldName( String[] fieldName ); String getPrefix(); void setPrefix( String prefix ); @Override void loadXML( Node stepnode, List<DatabaseMeta> databases, IMetaStore metaStore ); void allocate( int nrfields ); @Override Object clone(); @Override void setDefault(); @Override String getXML(); @Override void readRep( Repository rep, IMetaStore metaStore, ObjectId id_step, List<DatabaseMeta> databases ); @Override void saveRep( Repository rep, IMetaStore metaStore, ObjectId id_transformation, ObjectId id_step ); @Override void getFields( RowMetaInterface inputRowMeta, String name, RowMetaInterface[] info, StepMeta nextStep,
      VariableSpace space, Repository repository, IMetaStore metaStore ); @SuppressWarnings( "WeakerAccess" ) void assignSortingCriteria( RowMetaInterface inputRowMeta ); @Override void check( List<CheckResultInterface> remarks, TransMeta transMeta, StepMeta stepMeta, RowMetaInterface prev,
      String[] input, String[] output, RowMetaInterface info, VariableSpace space, Repository repository,
      IMetaStore metaStore ); @Override StepInterface getStep( StepMeta stepMeta, StepDataInterface stepDataInterface, int cnr, TransMeta transMeta,
      Trans trans ); @Override StepDataInterface getStepData(); String getSortSize(); void setSortSize( String sortSize ); boolean getCompressFiles(); void setCompressFiles( boolean compressFiles ); boolean isOnlyPassingUniqueRows(); void setOnlyPassingUniqueRows( boolean onlyPassingUniqueRows ); String getCompressFilesVariable(); void setCompressFilesVariable( String compressFilesVariable ); boolean[] getCaseSensitive(); void setCaseSensitive( boolean[] caseSensitive ); boolean[] getCollatorEnabled(); void setCollatorEnabled( boolean[] collatorEnabled ); int[] getCollatorStrength(); void setCollatorStrength( int[] collatorStrength ); String getFreeMemoryLimit(); void setFreeMemoryLimit( String freeMemoryLimit ); boolean[] getPreSortedField(); void setPreSortedField( boolean[] preSorted ); List<String> getGroupFields(); boolean isGroupSortEnabled(); @AfterInjection void afterInjectionSynchronization();  }### Answer:
@Test public void testGetDefaultStrength() { SortRowsMeta srm = new SortRowsMeta(); int usStrength = srm.getDefaultCollationStrength( Locale.US ); assertEquals( Collator.TERTIARY, usStrength ); assertEquals( Collator.IDENTICAL, srm.getDefaultCollationStrength( null ) ); }
