Tools for working with code coverage reports.
CVR has support for processing coverage in Cobertura, LCOV, Jacoco, and Go Cover. Coverage is translated first to a standard JavaScript format and then can be queried for coverage metrics including line, function, and branch coverage. There are also a set of tools for interacting with the GitHub API that make it easier to get files matching coverage reports.
Installation
CVR is a node module and does not have browser support.
npm install cvr
Basic Use
var cvr = ;cvr;
For more complicated examples, taking a look at /test/test.js
is recommended.
Common Coverage Object
Parsers are used for each coverage format to convert the diverse formats into a common format that is used internally for processing. This is the Common Coverage Object and documented on lcov-parse and reproduced below.
Methods
getCoverage( content, type, callback )
content
| String | the code coverage file contentstype
| String[ "lcov" | "cobertura" | "gocover" | "jacoco" ]
| the code coverage file typecallback
| Function | Callback argsError
,Array of Common Coverage Objects
getFileCoverage( coverageArray, filePath )
coverageArray
| Array of Common Coverage Objects | array of file coveragefilePath
| String | the file to find incoverageArray
- returns | Common Coverage Object | the first matching file found, or
undefined
getLine( lineCoverage, line )
lineCoverage
| Line Coverage from Common Coverage Object | array of file coverageline
| Number | the line number to find- returns | Object { active: true | false, hit: true | false | null }
active
whether a line was coveredhit
whether it was hit where andhit=null
whenactive=false
getLineCoveragePercent( coverageArray )
coverageArray
| Array of Common Coverage Objects | array of file coverage- returns | Number | percent of lines that have coverage
linesCovered( coverage )
coverage
| Common Coverage Objects | file coverage- returns | Array of Line Coverage | only the hit lines from the file
linesMissing( coverage )
coverage
| Common Coverage Objects | file coverage- returns | Array of Line Coverage | only the non-hit lines from the file
getFileType( filePath )
filePath
| String | the file name or path- returns | String | a file type based on
filePath
extension - "bash" | "css" | "go" | "javascript" | "less" | "markdown" | "python" | "sql" | "clike" (default for non-matched)
renderCoverage( coverage, source )
coverage
| Common Coverage Object | the file coveragesource
| String | the file contents- returns | String | HTML output wraps covered lines in
<span>
s to indicate whether the line was hit or not.
formatCoverage( coverage, source, filePath, callback )
Returns a complete template with code coloring and syntax highlighting, as compared to renderCoverage
which just returns an HTML snippet.
coverage
| Common Coverage Object | the file coveragesource
| String | the file contentsfilePath
| String | the file pathcallback
| Function, args err: Error, String: html |html
is created based on thesource/templates/basic.html
file
sortCoverage( coverageArray )
coverageArray
| Array of Common Coverage Objects | array of file coverage
