rspec 包含相等数组的匹配器失败

Question

我正在测试 SystemCommission 的 active 范围，我有以下测试：

  expected = [active, no_starting, no_ending]
  expect(SystemCommission.active.map(&:id)).to include expected.map(&:id)

它失败了：

Failure/Error: expect(SystemCommission.active.map(&:id)).to include expected.map(&:id)
       expected [1, 2, 3] to include [1, 2, 3]

我不得不使用 ids 因为它与对象不匹配。

有线索吗？

Answer 1

我认为include参数不是一个数组，而是一个项目列表，

所以将测试更改为：

  expect(SystemCommission.active.map(&:id)).to include *expected.map(&:id)

成功了

Answer 2

数组[1, 2, 3]不包含[1, 2, 3]

要通过它看起来像：[1, 2, 3, [1, 2, 3]]

展开你的数组：

expect(SystemCommission.active.map(&:id)).to include *expected.map(&:id)

rspec include matcher fails with equal arrays
