Test Framework

[tynes]

It would be ideal to add unit tests to hnsd so that its easier to develop without regressions. There are many options for test frameworks in C, many projects opt to roll their own framework. I found what I believe to be good options.

Options

• cmocka

  • Used by bind, libssh
  • Custom assertions
  • Simple to use, create an array of CMUnitTests using cmocka_unit_test which wrap describe like functions

• check

  • Designed to work with autotools
  • Simple, but a lot of boilerplate

• CGreen

  • Large, has many features
  • TDD/BDD support, along with Before, After, etc macros

• Custom

  • No extra dependencies
  • As simple as it needs to be
  • Must implement it, must be bugfree

I'd personally opt for using cmocka since it looks simple to use and is also used by other applications that are similar (DNS + security). It would be easier than creating our own custom test library.

We could use CI in the hsd repo too, CircleCI can install hnsd and we run it as a child_process with nodejs and run bmocha e2e tests. Tried a similar thing w bcoin: bcoin-org/bcoin#759

That would be good for integration tests, I am thinking more along the idea of unit tests here. Unit tests would be useful in particular for the resource serialization.

Made some progress in #68 and expanded in #76 but it might be nice to import one of these existing frameworks in the future.
