Package Exports

grunt-espower

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (grunt-espower) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

grunt-espower

A grunt task to apply espower to target files.

DESCRIPTION

grunt-espower is a grunt task to instrument "Power Assert" feature into your code.

Internally, grunt-espower task uses espower module that manipulates assertion expression (JavaScript Code) represented as Mozilla JavaScript AST, to instrument power-assert feature into the code. The magic is done by using Esprima and Escodegen.

Please note that grunt-espower is an alpha version product. Pull-requests, issue reports and patches are always welcomed. See power-assert project for more documentation.
