Mcover

MCover is a collection of macro based cross-platform code coverage and quality tools. MCover runs on all main Haxe targets including js, flash, neko, cpp and php.

To install mcover:

haxelib install mcover

MCover supports Haxe 2.10 and Haxe 3

Features

Code Coverage

MCover can provide detailed coverage of executed code, including:

• code blocks (statements)
• code branches

Example macro usage:

--macro mcover.MCover.coverage([''], ['src'])

Function logging

MCover can generate timing metrics around function entry/exit times, including:

• function start/exit time
• function duration (both inclusive and exclusive of nested methods)
• call stack depths

Example macro usage:

--macro mcover.MCover.logger([''], ['src'])

Cross Platform

MCover has been designed to work with any Haxe target. Officially we support the following:

• ActionScript
• JavaScript
• Neko
• CPP
• PHP

Code Coverage

For detailed information see src/m/cover/coverage/README.md

Compiler args

Add the following to your hxml file:

-lib mcover
--macro mcover.MCover.coverage(['{package}'], {classPaths}, {ignoredClasses})

Where:

• package is an array of packages to filter on (e.g. 'com.example'). Default is all packages - e.g. ['']
• classPaths is an array of classpaths to include (e.g. ['src']). Default is local path - e.g ['']
• ignoredClasses is an array of specific classes to ignore (e,g, ['com.example.IgnoredClass']). Default is null.

Example:

--macro mcover.MCover.coverage(['com.example'], ['src'], null)

Note: Only use single quotation marks (' ') to avoid compiler issues on windows platforms

Runtime report

Add the followng code to your application after code has executed:

var logger = mcover.coverage.MCoverage.getLogger();
logger.report();

Function Logging

For detailed information see src/m/cover/logger/README.md

Compiler args

Add the following to your hxml file:

-lib mcover
--macro mcover.MCover.logger(['{package}'], {classPaths}, {ignoredClasses})

Where:

• package is an array of packages to filter on (e.g. 'com.example'). Default is all packages - e.g. ['']
• classPaths is an array of classpaths to include (e.g. ['src']). Default is local path - e.g ['']
• ignoredClasses is an array of specific classes to ignore (e,g, ['com.example.IgnoredClass']). Default is null.

Example:

--macro mcover.MCover.logger(['com.example'], ['src'], null)

Note: Only use single quotation marks (' ') to avoid compiler issues on windows platforms

Runtime Usage

Add the followng code to your application to start recording

var logger = mcover.coverage.MCoverLogger.getLogger();
logger.startRecording();

Add the followng code to your application to stop recording and print report

var logger = mcover.coverage.MCoverLogger.getLogger();
logger.stopRecording();
logger.report();

Building from source

OSX: Use the build.sh bash script (osx only) Windows: Manually run steps within build.sh

Note: Make sure to set the dev path of mcover to /src before running tests (it's a bit tricky running code coverage on itself!)
