ruby - Rspec 匹配哈希数组

Question

我有一个哈希数组，为了便于论证，它看起来像这样:

[{"foo"=>"1", "bar"=>"1"}, {"foo"=>"2", "bar"=>"2"}]

使用 Rspec，我想测试 "foo"=> "2" 是否存在于数组中，但我不关心它是第一项还是第二项。我试过:

[{"foo" => "1", "bar" => "2"}, {"foo" => "2", "bar" => "2"}].should include("foo" => "2"))

但这行不通，因为哈希值应该完全匹配。有什么方法可以部分测试每个散列的内容吗？

Answer 1

怎么样？

hashes = [{"foo" => "1", "bar" => "2"}, {"foo" => "2", "bar" => "2"}]
expect(hashes).to include(include('foo' => '2'))
