示例1: test_reuse_custom_transform_instance
# 需要导入模块: from apache_beam.pipeline import Pipeline [as 别名]
# 或者: from apache_beam.pipeline.Pipeline import apply [as 别名]
def test_reuse_custom_transform_instance(self):
pipeline = Pipeline()
pcoll1 = pipeline | 'pcoll1' >> Create([1, 2, 3])
pcoll2 = pipeline | 'pcoll2' >> Create([4, 5, 6])
transform = PipelineTest.CustomTransform()
pcoll1 | transform
with self.assertRaises(RuntimeError) as cm:
pipeline.apply(transform, pcoll2)
self.assertEqual(
cm.exception.args[0],
'Transform "CustomTransform" does not have a stable unique label. '
'This will prevent updating of pipelines. '
'To apply a transform with a specified label write '
'pvalue | "label" >> transform')
