Coverage;T@
o;;;;[o;;0;["o;
;[ I"OSupport branch coverage and method coverage measurement. [Feature #13901] ;TI"KBranch coverage tells you which branches are executed, and which not. ;TI"IMethod coverage tells you which methods are invoked, and which not. ;TI"PBy running a test suite with this new feature, you can know which branches ;TI"Oand methods are executed by a test, and evaluate total coverage of a test ;TI"suite more strictly.;T@
o;
;[I"KYou can specify the measuring target by an option to `Coverage.start`:;T@
o:RDoc::Markup::Verbatim;[I"@Coverage.start(lines: true, branches: true, methods: true)
;T: @format0o;
;[I"LAfter some Ruby files are loaded, you can use `Coverage.result` to get ;TI"the coverage result:;T@
o;;[I"Coverage.result
;TI" #=> { "/path/to/file.rb"=>
;TI",# { :lines => [1, 2, 0, nil, ...],
;TI"# :branches =>
;TI")# { [:if, 0, 2, 1, 6, 4] =>
;TI"2# { [:then, 1, 3, 2, 3, 8] => 0,
;TI"1# [:else, 2, 5, 2, 5, 8] => 2
;TI"# }
;TI"# },
;TI"# :methods => {
;TI"0# [Object, :foo, 1, 0, 7, 3] => 2
;TI"# }
;TI"
# }
;TI" # }
;T;0o;
;[I"OThe result type of line coverage is not changed; it is just an array that ;TI"Jcontains numbers, which means the count that each line was executed, ;TI":or `nil`s, which means that the line is not relevant.;T@
o;
;[I"+The result type of branch coverage is:;T@
o;;[I"7{ (jump base) => { (jump target) => (counter) } }
;T;0o;
;[I"0where jump base and targets have the format;T@
o;;[I"K[type, unique-id, start lineno, start column, end lineno, end column]
;T;0o;
;[ I"RFor example, `[:if, 0, 2, 1, 6, 4]` reads an `if` statement that ranges from ;TI"Rline 2 and column 1, to line 6 and column 4. `[:then, 1, 3, 2, 3, 8]` reads ;TI"Sa `then` clause that ranges from line 3 and column 2, to line 3 and column 8. ;TI"ONote that lineno starts from 1, and that columnno starts from 0. So, the ;TI"Rabove example shows a branch from the `if` to the `then` was never executed, ;TI"Aand a branch from the `if` to the `else` was executed twice.;T@
o;
;[I"+The result type of method coverage is:;T@
o;;[I"#{ (method key) => (counter) }
;T;0o;
;[I"$where method key has the format;T@
o;;[I"N[class, method-name, start lineno, start column, end lineno, end column]
;T;0o;
;[I"SFor example, `[Object, :foo, 1, 0, 7, 3]` reads `Object#foo` that ranges from ;TI"Pline 1 and column 0, to line 7 and column 3. The above example shows this ;TI"$`Object#foo` was invoked twice.;T@
o;
;[I"UNote: To keep compatibility, passing no option to `Coverage.start` will measure ;TI"Jonly line coverage, and `Coverage.result` will return the old format:;T@
o;;[I"Coverage.result
;TI"6#=> { "/path/to/file.rb"=> [1, 2, 0, nil, ...] }
