640ce5360e Correct mutations of send to self 
* Invert the behaviour as this direction of mutation does make sense.

fb7bb942a3 Add mutation of simple send without arguments 
* Lets the block spec work again as 1.8 and 1.9 mode do not behave
  differend as with literals.

b9b95ebe94 Break up mutation spec in class specific files 
* Also add mutation class registry to improve readability.
* Calling mutations are still broken.

55c61dfc28 Add initial support for Rubinius::AST::{Send,SendWithArguments} 
* Only supports simple mutations currently.

9c08fad7ea Add noop mutator for Rubinius::AST::Self 2012-07-31 22:03:36 +02:00

7f3797ffa1 Introduce Mutant::Random 
* Cleans up naming duplication from the Mutant.random_* names.

75e6a229f8 Create namespace for literal mutations 
* Do not follow rubinius names anymore.
  An explict declaration now declares a mutator handles
  specific AST node.

* Has a nice impact on metrics.

d50ecc483d Cleanup missing whitespace after comma 
* There must be a code metric tool helping me in converting my style.

3e1f9c408f Cleanup and dedup mutation generation 
* Mutator and Generator where merged.
* A single pass over all duplications was made.
* It is clear a specific handles?(node) code for finding mutators
  is needed. Like virtus does for attributes, should also cache.
* Does not pass on 1.9 mode currently as blocks are unexpectly parsed
  differend when it comes to a series of literal booleans.

02a726d767 Retry on random mutates that are the same 
* This fixes problems where generated mutations have a chance
  to be the same like the mutation subject.

2b7e9c60c2 Simpify equal ast mutation with predicate. 2012-07-30 21:56:25 +02:00
Markus Schirp
ef9172bca4 Guard against the generation of equal mutants 
* Move Mutant::Mutator::Generator in a dedicated file
* Mutant::Mutator::Generator#append only forwards mutated node when it
  does not equal original nodes sexpession. This does not catch
  equivalent mutations, but mutations that exactly reproduce the same
  AST. This way a check for not generating the same asts can be
  centralized.

27f43eef35 Mutate float literals also to negative infinity 
* Also fixes invalid naming of support methods in literal float mutator.

0b9b46d12f Add range literal support 
* Full of duplication. Will be addressed when all literals are done.

9e8b451933 Add mutation for some literals 
* This is in progress code. The plan is to support all literals before
  beginning to cleanup and dedup the mutation generation. Have to
  understand the AST and the possible mutations more in depth before
  making structural decisions here.
