JSON to LCOV Converter

A small library that converts JSON to LCOV. I have used lcov-parse to convert infofile to JSON.

  • This module is for converting JSON back to infofile.
  • I have made 1 slight modification in the json object compared to lcov-parse. I have used filename as keys to input object.

Installation

npm install hitmap_json_to_lcov

JSON object format should match the below object

var validObject = {
    '/home/name/project/test.c': {
        'lines': {
            'found': 3,
            'hit': 2,
            'details': [
                {
                    "line": 1,
                    "hit": 2
                },
                {
                    "line": 2,
                    "hit": 10
                },
                {
                    "line": 3,
                    "hit": 0
                }
            ]
        },
        'functions': {
            'hit': 2,
            'found': 4,
            'details': [
                {
                    "name": "fn1",
                    "line": 1,
                    "hit": 2
                },
                {
                    "name": "fn2",
                    "line": 2,
                    "hit": 10
                },
                {
                    "name": "fn3",
                    "line": 3,
                    "hit": 0
                }
            ]
        }
    }
}

Usage

var hitmap_json_to_lcov = require('hitmap_json_to_lcov');

var result = hitmap_json_to_lcov(validObject);


Output should be `
SF:/home/name/project/test.c
FN:1,fn1
FN:2,fn2
FN:3,fn3
FNDA:2,fn1
FNDA:10,fn2
FNDA:0,fn3
FNF:4
