Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[9.0.0] - 2024-05-20

  • Support for crystal 1.12.1. Resolves warnings.

[8.0.1] - 2022-04-10

  • Support for crystal 1.4.0. Fixed a bug where the NumberLiteralSignFlip mutant would apply to unsigned integers

[8.0.0] - 2021-09-03

  • Support for crystal 1.1.1

[7.1.0] - 2021-09-03

Changed

  • Support for crystal 0.36.1
  • Dropped support for crystal < 0.35.0

Added

  • New mutant DropCallInVoidDef which replaces method calls with nil inside void methods
  • New mutant SymbolLiteralChange which modifies symbol literal with a prefix

[7.0.0] - 2020-04-10

Changed

  • Dropped support for crystal < 0.34.0

[6.0.1] - 2019-12-18

Added

  • New command crytic noop to output the code as crytic would run it. This helps with debugging, e.g. crytic noop | crystal eval
  • Crystal 0.31.x compatibility (no changes were needed for crystal 0.30.x). Be careful with crystal 0.31.0 and 0.31.1 because there is a bug that might cause your CI job to pass even with failing tests. See #8420.
  • Crystal 0.32.x compatibility

Changed

  • The stryker dashboard reporter only reports a successfull upload if the API responds with the correct status code

[6.0.0] - 2019-06-30

Changed

  • Bump required crystal version to 0.29.0

[5.0.1] - 2019-03-09

Fixed

  • When the production code requires e.g. ./html/builder, crytic will mimic crystal langs require and find html/builder/builder.cr

[5.0.0] - 2019-02-17

Added

  • New "File Summary" reporter that list the covered subjects and the number of mutations that were performed on each of those files respectively
  • When the neutral mutation errored, the output is shown as well
  • Ability to enable/disable reporters with --reporters/-r flag. Current reporters are Console, Stryker and ConsoleFileSummary

Changed

  • When no mutations were run, crytic now exits with 1 instead of 0
  • The StringLiteralChange mutant now performs more efficient replacements

Fixed

  • Don't crash in the stryker dashboard reporter when zero mutations were run
  • Fixed reporting of the number of mutations being run

[4.0.0] - 2019-01-31

Added

  • Run a "neutral" mutation before each subjects real mutations. This is @mjb's idea to validate the infrastructure of injecting mutations. Currently a "noop"-mutation is run, which simply doesn't mutate the subject at all.

Changed

  • The AndOrSwap mutant now swaps both || to && and && to ||

[3.2.3] - 2019-01-25

Fixed

  • The AndOrSwap mutant accidentally mutated multiple && at the same time

[3.2.2] - 2019-01-20

Fixed

  • Due to a regression introduced in 5a02821cce6bd27361bc84d5b073b21dc2fa55f0, require statements that don't yield any files could be left in the mutated code, leading to compile errors which looked like killed mutants

[3.2.1] - 2019-01-15

Fixed

  • Fix filename reporting introduced in 3.2.0

[3.2.0] - 2019-01-15

Added

  • Show filename (and line and col numbers) for both killed and surviving mutants in the console output

Fixed

  • Mutants AnyAllSwap and AndOrSwap could skip possible mutations

[3.1.1] - 2019-01-09

Added

[3.0.1] - 2019-01-08

Fixed

  • Exit after printing usage information, thanks @anicholson
  • Don't mutate unsigned integer literals like 1_u16 with the NumberLiteralSignFlip

[3.0.0] - 2019-01-03

Added

  • Simply running ./bin/crytic without any arguments will now automatically find all src files and specs
  • Introduced a mutant to swap [1].all? for [1].any?
  • Report number of mutations being run in console output
  • Introduced a mutant to swap any RegexLiteral for /a^/ which will never match
  • Enabled the mutant to swap #reject for #select and vice-versa

Fixed

  • When the mutated source code fails to compile this is now being noted correctly
  • Negative numbers are now correctly flipped to positive ones (e.g. -1 => 1 instead of -1 => --1)
  • Timeouts in mutations are printed as "not found" but are actually found and calculated as "killed". Fixed this so that timeouts are not showing a diff in the console output any more.
  • Errors resulting from mutations are printed as "bad" but actually mean that they were detected. Fixed this so that errors are not showing a diff in the console output.

[2.0.0] - 2018-12-06

Added

  • --min-msi cli argument to allow passing the suite (exiting with 0) even when there are mutants that survived. Pass as float like --min-msi=75.0.
  • Post MSI score to stryker dashboard if env vars are set.

Changed

  • NumberLiteralChange mutant now outputs 0 (for everything != 0) and 1 (for 0)
  • Depending on crystal 0.27.0, dropping all previous versions

[1.2.0] - 2018-10-29

Added

  • This changelog
  • Avoid hanging forever by imposing a timeout for mutations
  • Use "fail fast" option of crystal spec runner

Changed

  • Calculate the mutation score as MSI, described in infection

[1.1.0] - 2018-10-23

Added

  • More mutants: AndOrSwap, StringLiteralChange
  • Run CI on crystal 0.26.1 as well
  • Report a summary in the cli output

Changed

  • Don't report the number of times a mutant was run (e.g. (x2)) in the cli output

Fixed

  • Running multiple spec files as the test suite

[1.0.0] - 2018-10-20

Added

  • Everything. First release 🚀 🎉 💃
