Example 1 with TextFileOutputStepNode

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

the class MetaverseValidationIT method testTextFileOutputStepNode.

@Test
public void testTextFileOutputStepNode() throws Exception {
    TextFileOutputStepNode textFileOutputStepNode = root.getTextFileOutputStepNode("textFileOutput", "Text file output");
    TextFileOutputMeta meta = (TextFileOutputMeta) getStepMeta(textFileOutputStepNode);
    TransMeta tm = meta.getParentStepMeta().getParentTransMeta();
    String[] fileNames = meta.getFiles(tm);
    RowMetaInterface incomingFields = tm.getPrevStepFields(meta.getParentStepMeta());
    int outputFields = getExpectedOutputFieldCount(meta);
    assertNotNull(textFileOutputStepNode);
    Iterable<StreamFieldNode> outFields = textFileOutputStepNode.getOutputStreamFields();
    int outFieldCount = getIterableSize(outFields);
    // should have output stream nodes as well as file nodes
    assertEquals(outputFields + meta.getOutputFields().length, outFieldCount);
    int fileFieldCount = 0;
    for (StreamFieldNode outField : outFields) {
        if (DictionaryConst.NODE_TYPE_FILE_FIELD.equals(outField.getType())) {
            ValueMetaInterface vmi = incomingFields.searchValueMeta(outField.getName());
