[Idea]: develop a project test runner

[kgryte]

Idea

Currently, stdlib uses tape. The goal of this idea is to migrate away from tape and develop a test runner in-house, similar to @stdlib/bench/harness. This has long been on our TODO list and would allow us to have a simple test runner which is oriented toward stdlib conventions (e.g., we don't use most of the assertion methods in tape).

Bonus points if we can migrate away from istanbul to nyc or c8; however, this may be tricky if we want to support older Node.js versions.

Expected Outcomes

All unit tests have migrated to the in-house runner.

Involved Software

No additional runtime deps. Will need to consult tape as a reference implementation, along with our existing @stdlib/bench/harness implementation.

Prerequisite Knowledge

JavaScript, Node.js.

Difficulty

Intermediate.

Project Length

175/350 hours. The scope of this idea can be adjusted depending on availability.
