Customize test views
While Horreum does not require any particular format for the stored data you can use views to display summary information about each run. This is set in a view; each test defines it’s own view.
Defining a test view
Let’s assume you’ve already uploaded some data. Before setting up the view itself, we have to define how can Horreum fetch the value from the run data. This is where schema comes into play. Let’s define a new schema:
Login to Horreum, go to the ‘Schema’ tab and click ‘New Schema’:
Fill in the name and URI and hit the Save button on the bottom.
Switch tab to ‘Schema extractors and add 3 extractors, filling in the accessor - a symbolic identifier which will be used in the view - and PostgreSQL-syntax jsonpath to fetch the data from the run JSON. After that click Save again.
In the navigation bar on the top go to Tests and click either on the name or ID of your test. Switch to the Views tab and add first component, the CI link. When selecting the
ciUrl accessor pick ‘First match’ - we expect only one result for the jsonpath anyway.
Horreum will recognize the value as a hyperlink and automatically renders it.
The first parameter for your function is either the value extracted by the jsonpath (if you have only one accessor) or an object keyed according to your accessors. The second parameter is summary of the run used to display the whole row (most notably, there’s the
id column). The third parameter is current user’s OAuth token.
When you save the view, navigate to Tests and click on the link in Run Count column to see all runs for this test. You should notice two new columns on the right side, showing your custom view components.
You might be wondering why you can’t set the JSON path directly in the view; Tests, Runs and Schemas explains why this separation is useful when the format of your data evolves. However you don’t need to switch to the Schema when adding view components: when you start typing a non-existent accessor, you can add it to a schema in a modal dialogue.
We can continue with defining the variables for regression testing.
