selenium webdriver - How to increase the mocha timeout per suite in a typescript test -

i trying increase timeout mocha tests web requests form part of automated ui test suite , therefore can take longer default 2000ms.

the code works great if call mocha --timeout set 5000ms or default 2000ms not enough.

i want able set timeout per test suite timeout becomes part of success criteria might different on case case basis.

before(()=>{   var sw = require('selenium-webdriver');   this.driver = new sw.builder().withcapabilities(sw.capabilities.chrome()).build();   var c = require('chai');   c.use(require('chai-webdriver')(this.driver));   this.expect = c.expect;   return this.driver.getwindowhandle(); })  after(() => {   return this.driver.quit(); })  describe('looking @ github', () => {   beforeeach(() => {     this.driver.get('http://stackoverflow.com/');   })   describe('when take @ stack overflow home page', () => {     return it('it not have crazy cat text in it!', () => {       return this.expect('#h-top-questions').dom.to.not.contain.text("just cats here!");     });   }); }) 

use function intead of arrow , call this.timeout(5000); e.g.

describe('when take @ stack overflow home page', () => {     return it('it not have crazy cat text in it!', function() {       this.timeout(5000);       return this.expect('#h-top-questions').dom.to.not.contain.text("just cats here!");     });   }); 

this because ()=> captures surrounding this. more http://basarat.gitbooks.io/typescript/content/docs/arrow-functions.html
