Full-stack dev quiz question #8

Full-stack dev quiz question #8

Attention, attention! Testing knowledge is required. The eighth question of the quiz for a full-stack developer is about Spock Framework.

SetTimeout seems familiar? Check the answer to the seventh question.

The below code is Groovy with Spock Framework.

    1 * basketsRepository.save(_) >> { arguments ->
        final Apple apple = arguments.get(0)
        assert apple == new Apple(weight: 0.123)    }

What does it do? Choose one answer.

1. Mocks a local apple variable in the save method.
2. Checks if the apple local variable used in the save method equals an Apple object with weight = 0.123.
3. Tests if the save method is executed once with an Apple object that has weight = 0.123.
4. Does computation. Result of the save method is multiplied by 1 and passed to the lambda expression.
5. Stubs a method. When the save method is executed for the first time, an Apple object with weight = 0.123 is returned.
