Data Sources

The Data Sources section is required in the Visualization XML to inform Galaxy of the compatible data types for your visualization. If your visualization does not need a pre-existing dataset, set required="false" on the <param> definition.

<data_sources>
    <data_source>
        <model_class>HistoryDatasetAssociation</model_class>
        <test test_attr="ext">{{ COMPATIBLE_EXTENSION }}</test>
    </data_source>
</data_sources>
<params>
    <param required="true">dataset_id</param>
</params>

Tests

You may also add a <tests> section which allows you to define test cases for your visualization. These help ensure that the plugin works correctly when given specific inputs. Each test can specify a URL to a file and its corresponding Galaxy datatype type (ftype). Users will be able to upload the dataset and invoke the visualization.

<tests>
    <test>
        <param name="dataset_id" value="http://cdn.jsdelivr.net/gh/galaxyproject/galaxy-test-data/1.{{ COMPATIBLE_EXTENSION }}" ftype="{{ COMPATIBLE_EXTENSION }}" />
    </test>
</tests>

You can use any public URL pointing to test data, ideally from a maintained repository such as galaxy-test-data.
