This implementation must perform two things: To capture the DataTable into a useable domain object, we'll create a BookCatalog class: To perform the transformation, let's implement the TypeRegistryConfigurer interface: and then implement the TableTransformer interface for our BookCatalog class: Note that we're transforming English data from the table, and therefore, we return the English locale from our locale() method. To handle this, we create a data table in our scenario: We define our data table as a part of our Given clause by indenting the table underneath the text of the Given clause. Then we iterate over each Map object and extract each column value using the column header as the key: The final (and most rich) mechanism for converting data tables to usable objects is to create a TableTransformer. Most lines in a Gherkin document start with one of the keywords.. Additionally, data tables can be used with any clause — not just Given clauses. "Scalar" from the Cucumber javadocs may have been incorrectly used to collectively mean the associated wrapper class of the primitives (i.e. In many cases, these scenarios require mock data to exercise a feature, which can be cumbersome to inject — especially with complex or multiple entries. We would remove the skip(1) call if our table did not include a header. Cucumber provides a list of maps mechanism as a more readable alternative.

This is now resolved for me after updating to the newer version of cucumber-core. Data Tables in Cucumber are quite interesting and can be used in many ways. The constructor may accept all fields as parameters. Declare the argument as a List, but don’t define any capture groups in the expression: If the Datatable contains only one column then Data Table is automatically flattened to a List by Cucumber (using DataTable.asList(String.class)) before invoking the step definition. Lastly, we add each created Book object to our BookStore object. I would like some clarification on what "scalar" means in this context. Given I have the following DataTable: Then the List of Film grid details for this Film should be: ...

Declare the argument as a List, but don’t define any capture groups in the expression: If the Datatable contains only one column then Data Table is automatically flattened to a List by Cucumber (using DataTable.asList (String.class)) before invoking the step definition. In this tutorial, we'll look at how to use Cucumber data tables to include mock data in a readable manner. In the example given in step definitions, Cucumber extracts the text 48 from the step, converts it to an intand passes it as an argument to the methodfunctionblockfunction.
