High Level Overview of Change

Adds RPC error verification functionality to unit tests. There are two ways to specify the expected result:

  1. By RPC code and an optional detail message. If a detail message is not specified, it will be expected to match the message defined in the RPC code lookup table.
  2. By the expected error string, and an optional error_exception detail message. If the detail message is not specified, it will not be checked.

These checks are not comprehensive (for example, nothing checks the optional error_what field), but I think they are sufficient for any expected test case results.

Context of Change

PR #4887 introduced a new TER result code to indicate that an RPC request failed during transaction processing, but it does not indicate which RPC failure occurred. Inspired by a discussion on that PR, I added the ability to explicitly check the RPC result.

(Props to @ckeshava for the pre-review.)

Type of Change

  • Tests (you added tests for code that already exists, or your new feature included in this PR)

API Impact

None.

Test Plan

There should be no observable external effects for this change. This is a developer tool to help write more and better unit tests.

Future Tasks

Now that we can distinguish RPC failures, it might be useful to add more test cases that explicitly test the various combinations of failures. (Thanks to @ckeshava again for the suggestion.]

I feel this comment is more appropriate in src/test/jtx/rpc.h. Specifically, in the operator() of the rpc class.

This looks like a good change and the implementation is pretty clever. I spotted a few changes that might be improvements, but feel free to push back on any of them. I put all of my suggestions into a commit that you can see here: https://github.com/scottschurr/rippled/commits/ed-jtx_rpc/ You probably don't want to take all of my suggestions, but the commit will at least show you what I was thinking.
