使用Spock进行测试-使用复杂的数据提供程序

Question

Spock can run parametrized tests using the Data Pipes construct:

...
where:
a << [1, 7, 0]

It's very convenient for lists of values or one-liners that generate some custom list (eg a << (0..9).collect({it*it}) But what's a convenient, readable way of providing a complex generated list as a parameter? A list that can't be easily generated in a single line of code.

Edit: I realize that I use a separate static method to initiate the list, but that feels hackish, and I'm wondering whether there is a way of generating the parameters somewhere within the test itself. The where clause itself doesn't allow anything of that sort.

Answer 1

In case you mean complex list as list of objects, you can always break the objects to the relevant fields you are using in the test.

For example: If you need a list of students, each student has the following data:

class Student {
    String name
    String lastname
    Int age
    String id
}

In the test you can build each object by divide it to its fields. So use the where section like that:

  where:
    name    | lastname | age | id
    "Ron"   | "Black"  | 34  | "2345"
    "Tom"   | "White"  | 26  | "8765"

Using that syntax enable you to have different object in every iteration, as defined in the where section.

I hope that is what you are looking for, because your question can be understood in different ways.
