|
|
|
|
|
|
B<ETL::Pipeline::Input::UnitTest> is an input source used by the unit tests. |
19
|
|
|
|
|
|
|
It proves that the L<ETL::Pipeline::Input> role works. |
20
|
|
|
|
|
|
|
|
21
|
|
|
|
|
|
|
The I<data> is hard coded. |

None - there's no configuration for this source. It's meant to be quick and |
42
|
|
|
|
|
|
|
light for unit testing. |

This is the main loop. For unit tests, I use hard coded data. This guarantees |
49
|
|
|
|
|
|
|
consistent behavior. |

|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
L<ETL::Pipeline> automatically calls this method. |
