Create mutator that targets the following grammar rules.

expression :
    | ('+' | '-' | '++' | '--') expression

This mutator should create mutants using the following transformation:

Create mutator that targets the following grammar rules.

expression :
    | expression ('++' | '--')
    | ('+' | '-' | '++' | '--') expression

This mutator should create mutants using the following transformations:

Create mutator that targets the following grammar rules (only when expressions are numeric; string concatenation should be ignored!). Note: May need to create separate mutator for mutating addition operator.

expression :
    |   expression ('*'|'/'|'%') expression
    |   expression ('+'|'-') expression
    |   expression ('<' '<' | '>' '>' '>' | '>' '>') expression
    |   expression '&' expression
    |   expression '^' expression
    |   expression '|' expression

This mutator should create mutants using the following transformation:

Currently, the program only creates mutant classes. In practice, tests are written once for a class. These tests will not test the mutants that are created unless they are modified to do so. So, whenever a mutant is created, we need to also copy the original tests and modify them so they test the mutant.

Create a mutator that returns empty values depending on method return type.

Proposed:

• String returns empty string
• List, Set, Map return their respective empty types
• Numeric = 0
• Boolean = False

Create a mutator that replaces return statements with return null; (except those that already return null).

Create mutator that removes method calls to void methods.

Mutation testing should be able to be automatically directed into a Salesforce org using current SFDX configuration. (If an alias exists to an org, they can use that to choose target Salesforce org and connect/run testing).

Create mutator that targets the following grammar rules.

expression :
    |   expression ('<=' | '>=' | '>' | '<') expression
    |   expression ('==' | '!=' | '<>') expression

This mutator should create mutants using the following transformation:

Add dependency recognition to reduce number of tests required to run per mutant.
