### Question:
SortRowsMeta extends BaseTransformMeta implements ITransformMeta<SortRows, SortRowsData>, 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 transformNode, IHopMetadataProvider metadataProvider ); void allocate( int nrFields ); @Override Object clone(); @Override ITransform createTransform(TransformMeta transformMeta, SortRowsData data, int copyNr, PipelineMeta pipelineMeta, Pipeline pipeline); @Override void setDefault(); @Override String getXml(); @Override void getFields(IRowMeta inputRowMeta, String name, IRowMeta[] info, TransformMeta nextTransform,
                        IVariables variables, IHopMetadataProvider metadataProvider ); @SuppressWarnings( "WeakerAccess" ) void assignSortingCriteria( IRowMeta inputRowMeta ); @Override void check(List<ICheckResult> remarks, PipelineMeta pipelineMeta, TransformMeta transformMeta, IRowMeta prev,
                    String[] input, String[] output, IRowMeta info, IVariables variables,
                    IHopMetadataProvider metadataProvider ); @Override SortRowsData getTransformData(); 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 ) ); }
