invalid usage of delete operator #246
Description
There is usage of the delete operator in the method add (browser/queue.js). This construction is not valid in the strict mode so it leads to fail when FuncUnit is imported as a ES6 module.
add = function(handler, error, context) {
if(handler instanceof Function) {
if(typeof error === 'object') {
context = error;
delete error;
}
error = (error && error.toString()) || 'Custom method has failed.';Found in the npm version 3.7.0
