@Test
public void testOpen(final @Mocked PageReader reader, final @Mocked PageBuilder builder, final @Mocked Page page) throws Exception {
new NonStrictExpectations() {{
taskSource.loadTask(PluginTask.class); result = task;
task.getDelimiter(); result = "";
reader.nextRecord(); result = true; result = false;
}};
SpeedometerFilterPlugin plugin = new SpeedometerFilterPlugin();
PageOutput output = plugin.open(taskSource, schema, schema, inPageOutput);
output.add(page);
new Verifications() {{
taskSource.loadTask(PluginTask.class); times = 1;
builder.addRecord(); times = 1;
builder.finish(); times = 0;
