Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. assert semver.cmp evaluates relational operators greater-than, less-than, and their inclusive variants
  2. assert semver.cmp evaluates equality and inequality operators comparing semantic version equivalence
  3. assert semver.cmp evaluates strict equality and strict inequality operators comparing exact version strings
  4. assert semver.cmp treats empty string and single equals sign as equal comparisons
  5. assert semver.cmp throws TypeError when an invalid comparison operator is supplied
  6. assert semver.cmp respects options including loose mode and includePrerelease
