Feature request summary

Enabling the ability to specify a custom starting point in the actual side JSON hierarchy will allow test writers to make the testing intent more clear:

1. The actual JSON does not have to be manipulated
2. The expected JSON does not need wrapper containers to match the hierarchy of actual

This supports the use case of test case validation that is only interested in a specific child node in the JSON hierarchy onwards. With the change, the user no longer has to maintain the JSON hierarchy outside of what they actually want to validate

Current behavior

For example, in the current system given
actual

{
  "level1": {
    "level2": {
      "level3": 3
    }
  },
  "key1": 1,
  "key2": 2
}

your expected would have to be:

{
  "level1": {
    "level2": {
      "level3": 3
    }
  }
}

Expected behavior

With this new proposal, it could be:
actualStartPath: "level1.level2" +

{
  "level3": 3
}
