Example 1 with SplitFieldsStepNode

use of org.pentaho.metaverse.frames.SplitFieldsStepNode in project pentaho-metaverse by pentaho.

the class MetaverseValidationIT method testSplitFieldsStepNode_normal.

@Test
public void testSplitFieldsStepNode_normal() throws Exception {
    SplitFieldsStepNode node = root.getSplitFieldsStepNodeByName("Split Fields - name");
    assertNotNull(node);
    FieldSplitterMeta meta = (FieldSplitterMeta) getStepMeta(node);
    assertEquals(meta.getDelimiter(), node.getDelimiter());
    assertEquals(meta.getEnclosure(), node.getEnclosure());
    String[] outputFields = meta.getFieldName();
    Iterable<StreamFieldNode> usedFields = node.getStreamFieldNodesUses();
    int usedFieldCount = getIterableSize(usedFields);
    assertEquals(1, usedFieldCount);
    assertEquals(meta.getSplitField(), usedFields.iterator().next().getName());
    // make sure the split field derives all of the output fields
    Iterable<StreamFieldNode> outFields = node.getOutputStreamFields();
    for (StreamFieldNode outField : outFields) {
