Defined in:
lib/rspec_sprint/collector.rb

Overview

Runs the host project’s RSpec suite ONCE with FactoryProf JSON enabled and RSpec’s JSON formatter writing to a dedicated file (so the host’s own formatter on stdout is not clobbered — design D10③). Returns a Result that downstream code (Diagnosis) and degraded-path handling read.

The pure pieces (build_command, factory_prof_path_from) are split out so most behavior is unit-testable without spawning a real rspec process.

Class Method Details

.build_command(out_path:, rspec_args: []) ⇒ Object

Pure: the env + argv used to run rspec. FPROF=json makes test-prof write its FactoryProf JSON; –format json –out writes rspec’s JSON to its own file without replacing the host’s stdout formatter.

def self.build_command(out_path:, rspec_args: [])
  env = { "FPROF" => "json" }
  argv = ["bundle", "exec", "rspec", "--format", "json", "--out", out_path, *rspec_args]
  [env, argv]
end

.factory_prof_path_from(stdout) ⇒ Object

Pure: pull the FactoryProf output path test-prof logs to stdout. nil means test-prof never ran (not required in the host’s boot) — Rule① will be skipped.
