1.0.3 (2026-07-26)

Bugfixes

• Generating a report no longer crashes when the coverage universe contains a module that shadows #inspect with an incompatible signature. Rendering a method coverage key's receiver calls to_s, and a singleton class's to_s renders its attached object via #inspect — Liquid's Utils module defines inspect(value, max_depth = 2) as a module_function, so any suite whose report included Liquid's files (typically a vendored bundle under the project root, which is why this surfaced only in CI) raised ArgumentError from the at_exit hook and lost its report. The exposure predates 1.0.2's key normalization, which only moved the call. Rendering now recovers by rebuilding the name from Module#name via bound methods, which user code cannot shadow, falling back to an address form that the existing normalization collapses. The external_at_exit workaround is no longer needed. Reported with an exemplary diagnosis by @​bkuhlmann. See #1236.
• Method coverage entries are now aggregated by source location alone, completing the aggregation introduced in 1.0.2 (which keyed on name and location). Ruby records one method entry per defined method, so a builder looping container.each_key { |key| define_method(key) { ... } } produces an entry per generated name, all at the block's location — and every name whose generated wrapper no test happened to call showed as an uncovered method on a line with full line and branch coverage. A source location is the unit a file-based report can express, and regular defs map one location to one name, so they are unaffected. The same identity is used when merging resultsets across processes. This also covers methods copied into refinements via import_methods, which Ruby records once per importing refinement at the shared module's original location, so exercising the method through any refinement now marks the shared definition covered and the skip workaround for shared refinement modules can be dropped. Reported with exemplary diagnoses by @​bkuhlmann. See #1234 and #1237.
• SimpleCov.formatter and SimpleCov.formatters now accept formatter instances in addition to formatter classes, so constructor options can actually be passed — most notably SimpleCov::Formatter::HTMLFormatter.new(silent: true) to suppress the "Coverage report generated" status line. Previously SimpleCov unconditionally called .new on whatever was configured, so passing an instance crashed with NoMethodError at report time. See #1240.

Performance

• Fix 5x performance regression on report combining (introduced in 1.0.0 as a result of using Ripper#parse in a hot path) by adding parsed key memoisation to RubyDataParser.call.

1.0.2 (2026-07-18)

Bugfixes

• The standalone simplecov CLI's colorizing subcommands (report, uncovered, coverage, diff) no longer crash with NoMethodError: undefined method 'color' when run in a project without a .simplecov file. The CLI deliberately loads only simplecov/cli rather than the full library, so SimpleCov.color was undefined unless a dotfile load had incidentally defined it — and --no-color was the only workaround, since the documented NO_COLOR env var was checked after the line that raised. Color.enabled? now treats missing configuration the same as its :auto default and falls through to NO_COLOR / FORCE_COLOR / TTY detection. Reported with an exemplary diagnosis by @​hasghari. See #1231.
• Branch tuples synthesized for tracked-but-unloaded files now match Ruby's Coverage for a safe-navigation call that takes a block. For x&.foo { ... } (and the second link of a chain like x&.foo&.bar { ... }) the extractor keyed the branch on the call node's full source range, which extends through the attached block, while Coverage ends the range at the call itself — so a simulated entry merging with a real one produced a phantom, permanently-missed branch, the same failure mode as the elsif fix in 1.0.1. Reported with an exemplary diagnosis and a suggested fix by @​alexdeng-mp. See #1233.
• Prompted by the two reports above, an exhaustive differential audit of StaticCoverageExtractor against Ruby's Coverage — a fuzzing harness that runs thousands of generated programs through both and diffs the branch tuples, now part of the spec suite (opt-in via SIMPLECOV_FUZZ=1) — surfaced and fixed four more mismatches of the same phantom-branch class. Conditions that are compile-time literals (if true, if 1, a ternary on a literal) are folded away by Ruby's compiler and no longer produce synthesized branches (while true still does — loops are not folded). On Ruby 3.3, three legacy conventions now match: the body range of a do-while (begin ... end while), the location of empty branch arms (which on 3.3 depends on whether the construct is in value or void position), and one-line pattern matching (x => pattern / x in pattern), which emits a :case branch on 3.3 and nothing on 3.4+. The audit also caught a crash on Ruby 3.3's stdlib Prism (0.19), which still exposes the else clause of UnlessNode / CaseNode / CaseMatchNode under its pre-1.3 name consequent: the extractor raised internally and silently dropped simulated branch and method data for any file containing unless/else or a case with an empty arm, unless a newer prism gem happened to be installed.
• As a defensive layer against any future extractor drift, merging now treats an actually-executed file's branch and method data as authoritative: when a resultset that merely tracked a file (with simulated, statically-derived tuples) merges with one from a process that really loaded it, the synthesized tuples are dropped rather than unioned. This contains any undiscovered mismatch to denominator inflation on files no process loaded, instead of phantom misses on fully-covered ones. Line coverage still combines from both sides, so tracked-but-unloaded files keep contributing to the line denominator as before.
• Method coverage no longer reports phantom uncovered methods for define_method / define_singleton_method blocks defined onto more than one receiver — e.g. a module's included hook defining the same block on every including class. Ruby records one method entry per receiver, all pointing at the same source location, so any receiver whose copy was never called showed as an uncovered method on a line with 100% line coverage. Entries are now aggregated by (name, source location) with hit counts summed, and cross-process merging matches methods on the same source identity rather than on the receiver class. Reported with an exemplary diagnosis by @​bkuhlmann. See #1234.
• Branch coverage under enable_coverage :eval no longer inflates denominators or reports phantom missed branches for templates compiled more than once — e.g. hanami-view compiles each template once per view class, and every ERB.new(...).result is a fresh compile. Ruby's Coverage emits a fresh set of branch entries per compile of the same file (nondeterministically through Ruby 4.0, consistently on current ruby master — see https://bugs.ruby-lang.org/issues/22203), each counting only the renders that flowed through that compile, so a side exercised under one compile appeared as a permanently-missed branch in another compile's entry at the same location, and ignore_branches :implicit_else swung the report wildly by stripping only the synthetic-else halves of the duplicates. Duplicated conditions are now aggregated by source location with arm counts summed. Reported with an exemplary diagnosis by @​bkuhlmann. See #1235.
