mathjs/test/README.md

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices.

## Tests

To execute the tests, install `mocha ` and run the following in the root of
the project:

    npm install -g mocha
    mocha test --recursive

It's important to run mocha with the `--recursive` flag, as most tests are
located in nested folders.


## Code coverage

To test code coverage of the tests, install `istanbul` and run it:

    npm install -g istanbul
    istanbul cover _mocha -- test --recursive

Note the underscore before mocha, and the `--` surrounded by spaces after _mocha.
