rspec包括matcher以相同的数组失败

Question

我正在测试active的{​​{1}}范围，我有以下测试：

SystemCommission

它失败了：

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

我不得不使用Failure/Error: expect(SystemCommission.active.map(&:id)).to include expected.map(&:id) expected [1, 2, 3] to include [1, 2, 3] ，因为它与对象不匹配。

任何线索？

Answer 1

数组[1, 2, 3]不包含[1, 2, 3]

要进行该传递，它将类似于：[1, 2, 3, [1, 2, 3]]

splat你的阵列：

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

Answer 2

我认为include参数不是数组，而是项目列表

将测试更改为：

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

做了这个伎俩
