  ● hello

    assert.equal(received, expected) or assert(received)

    Expected value to be equal to:
      {"Fu": {"Fe": 1}, "greeting": "Hello"}
    Received:
      {"Fu": {"Ho": 1}, "geeting": "WayWayWa"}

    Message:
        # hello.test.ts:4

      assert.equal({ geeting: "WayWayWa", Fu: { Ho: 1 } }, { greeting: "Hello", Fu: { Fe: 1 } })
                   |                          |            |                        |
                   |                          |            |                        Object{Fe:1}
                   |                          Object{Ho:1} Object{greeting:"Hello",Fu:#Object#}
                   Object{geeting:"WayWayWa",Fu:#Object#}


    Difference:

    - Expected
    + Received

      Object {
        "Fu": Object {
    -     "Fe": 1,
    +     "Ho": 1,
        },
    -   "greeting": "Hello",
    +   "geeting": "WayWayWa",
      }
