javascript - While loops in protractor -


i have started using protractor e2e tests. have combobox lists events match user types in - list empty if no such events found.

what enter 3 random characters, , if combobox list empty, clear combobox , retry 3 random characters. should repeated until non-empty list found.

i have tried using simple while loop this, asynchronous nature of webdriverjs means become stuck in infinite loop. possible somehow wait inside loop combobox populated? or there other, cleaner solution problem?

code:

var query = element(by.model('searchstr'));  query.clear();  var letters = generaterandomletters();  console.log(letters);  query.sendkeys(letters);  var eventlist = element.all(by.repeater('result in results'));  eventlist.count().then(function(count) {      if(count) {          //test continues here      }  });

declare function calls recursively until condition met. should trick.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
