icj

icj

An Istanbul coverage juggler. This is a command line tool that allows you to juggle Istanbul coverage files, where for various reasons it is difficult to get the output you desire.

Installation

To install, simply add to a projects package.json or install globally:

$ npm install icj -g

Commands

filter

The filter command is designed to filter JSON coverage information from Istanbul JSON coverage files. By default it would take a coverage-final.json file as input and output a coverage-filter.json filtering only coverage patterns that match coverage for TypeScript files that are part of a webpack bundle in the ./src/app path, excluding any .spec.ts test files.

The usage for the filter command is:

icj filter [input] [output]

It currently supports the following options:

Option	Value	Description
-p or --pattern	String	A minimatch glob string of the files to include in the filtered coverage data. Default value is: **/webpack:/src/app/**/!(*.spec).ts

Configuration

icj supports configuration via the package.json under the "icj" key. For example, to configure the filter command, it would look something like this:

{
    "icj": {
        "filter": {
            "input": "output/coverage-final.json",
            "output": "output/coverage-filtered.json",
            "pattern": "**/webpack:/src/app/**/!(*.spec).ts"
        }
    }
}
