I'm using CasperJS to run tests with PhantomJS. I added this code to my tearDown function:

var require = patchRequire(require);
var fs = require('fs');

casper.test.begin("My Test", {
    tearDown: function(){
        casper.capture("export.png");
        fs.write("1.html", casper.getHTML(undefined, true), 'w');
    },
    test: function(test){
        // test code

        casper.run(function(){
            test.done();
        });
    }
});

See docs for capture and getHTML.
