[DiamondDagger590]

Summary

• ParserAdditionalBranchCoverageTest (10 tests): Covers underscore-prefixed variable names (isText c == '_' branch), single-underscore variables, built-in constants (pi, e), convertInput stripping unrecognized characters, implicit multiplication (constant × variable and constant × function), and the Parser(String, true) error mode with both unset and set variables.
• SfunAdditionalBranchCoverageTest (9 tests): Covers cot(0) returning positive infinity (y == 0.0 branch), gamma overflow (x=172), underflow (x=-170.7), and negative integer (x=-11) branches, logGamma NaN for negative integers, logBeta dlnrel path with very small arguments, and fact boundary cases (n<0 → NaN, n>170 → infinity, n=0 → 1).
• PaginatedGuiAdditionalBranchCoverageTest (1 test): Covers the getMaximumPage() >= 1 precondition in setPage() when getMaximumPage() returns 0.

Scope

These tests target branches not covered by any of the 30 currently open test PRs (#91–#120). No production code was changed.

Test plan

• All 3 new test files compile and pass
• Full test suite passes with no regressions
• Testing audit persona reviewed changes; feedback addressed (removed duplicate tests, fixed weak assertion, added error-mode test)

Summary by CodeRabbit

• Tests
  • Expanded automated coverage for pagination edge cases, including invalid page selections.
  • Added parser coverage for special variables, constants, implicit multiplication, input handling, and evaluation errors.
  • Added mathematical function coverage for boundary conditions involving cotangent, gamma, log-gamma, log-beta, and factorial calculations.
  • Improved confidence in consistent behavior across parsing, pagination, and numerical computations.

📝 Walkthrough

Walkthrough

The pull request adds branch-coverage tests for paginated GUI validation, parser behavior, and special-function boundary cases.

Changes

Branch coverage tests

Layer / File(s)	Summary
Pagination validation src/test/java/com/diamonddagger590/mccore/gui/PaginatedGuiAdditionalBranchCoverageTest.java	Adds fixtures and a test that verifies setPage(1) throws IllegalArgumentException when the maximum page is zero.
Parser branch coverage src/test/java/com/diamonddagger590/mccore/parser/ParserAdditionalBranchCoverageTest.java	Tests underscore variables, input strings, constants, character filtering, implicit multiplication, and error-mode evaluation.
Special-function branch coverage src/test/java/com/diamonddagger590/mccore/parser/SfunAdditionalBranchCoverageTest.java	Tests boundary behavior for cot, gamma, logGamma, logBeta, and fact.
