Regarding the mathematics of expectations, there are a series of rewrite rules on the part of the class PhexMatcher. This screencast explains how to use the RB: Code Critics rewrite mechanism in OB (Screencast 3 OB) .
Use these rules first
RBParseTreeRewriter new
replace: 'self assert: [ `@expression ]' with: 'self assert: `@expression';
replace: 'self deny: `@expression' with: 'self assert: `@expression not';
yourself.
Then use these rules
RBParseTreeRewriter new
replace: 'self assert: `@value = `@expected' with: '`@value should = `@expected';
replace: 'self assert: `@value ~= `@expected' with: '`@value should not = `@expected';
replace: 'self assert: `@value > `@expected' with: '`@value should > `@expected';
replace: 'self assert: `@value < `@expected' with: '`@value should < `@expected';
replace: 'self assert: `@value >= `@expected' with: '`@value should >= `@expected';
replace: 'self assert: `@value <= `@expected' with: '`@value should <= `@expected';
replace: 'self assert: (`@value isKindOf: `@type)' with: '`@value should beKindOf: `@type';
replace: 'self assert: `@expression isNil' with: '`@expression should be isNil';
replace: 'self assert: `@expression notNil' with: '`@expression should be notNil';
replace: 'self assert: `@expression `test not' with: '`@expression should not be `test'
when: [:node | node arguments first receiver selector matchesRegex: '(is|has|not).+|atEnd' ];
replace: 'self assert: `@expression `test' with: '`@expression should be `test'
when: [:node | node arguments first selector matchesRegex: '(is|has|not).+|atEnd' ];
replace: 'self assert: (`@collection includes: `@element) not' with: '`@collection should not be includes: `@element';
replace: 'self assert: (`@collection includes: `@element)' with: '`@collection should be includes: `@element';
yourself.
