Тестирование

Тестирование сервисов Servactory аналогично тестированию обычных классов Ruby.

TestKit

Servactory::TestKit::FakeType

Для негативного тестирования типов входящих атрибутов Servactory предоставляет класс Servactory::TestKit::FakeType.

Servactory::TestKit::Result

Для мока результата сервисов Servactory предоставляет специальный класс Servactory::TestKit::Result.

before do
allow(UsersService::Create).to(
receive(:call).and_return(Servactory::TestKit::Result.as_success)
)
end
before do
allow(UsersService::Create).to(
receive(:call).and_return(
Servactory::TestKit::Result.as_failure(
exception: Servactory::Errors::Failure.new(
message: "Some error"
)
)
)
)
end
