Class: FastCov::ConstGetTracker

Inherits:
AbstractTracker show all
Defined in:
lib/fast_cov/trackers/const_get_tracker.rb

Overview

Tracks constants looked up dynamically via Module#const_get.

This catches dynamic constant lookups that static analysis misses:

  • Object.const_get(“Foo::Bar”)

  • Rails’ “UserMailer”.constantize (uses const_get under the hood)

  • Any metaprogramming that looks up constants by string name

Note: This does NOT catch direct constant references like ‘Foo::Bar` in source code - those compile to opt_getconstant_path bytecode and bypass const_get.
