Examples of org.jacoco.report.IReportVisitor

org.jacoco.report.IReportVisitor
Interface for all implementations to retrieve structured report data. Unlike nested {@link IReportGroupVisitor} instances the root visitor accepts exactly onebundle or group.


  @Test
  public void testStructureWithNestedGroups() throws IOException {
    final ICoverageNode root = new CoverageNodeImpl(ElementType.GROUP,
        "root", false);
    final IReportVisitor child = formatter.createReportVisitor(root);
    driver.sendGroup(child);
    driver.sendGroup(child);
    child.visitEnd(driver.sourceFileLocator);
    final List<String> lines = getLines();
    assertEquals(HEADER, lines.get(0));
    assertEquals(
        "root/group/bundle,org.jacoco.example,FooClass,0,1,0,0,0,0,0,0",
        lines.get(1));
