Null Pointer Exception when running selenium webdriver testcase using internet explorer driver -


below code:

package mypackage; import java.io.file; import org.openqa.selenium.by; import org.openqa.selenium.webdriver; import org.openqa.selenium.ie.internetexplorerdriver;  public class myclass { public static webdriver driver; public static file file; public static void main (string[] args){  // declaration , instantiation of objects/variables file = new file("c:\\data\\iedriverserver_x64_2.42.0\\iedriverserver.exe"); system.setproperty("webdriver.ie.driver", file.getabsolutepath());   driver = new internetexplorerdriver(); string baseurl = "http://www.google.com"; string expectedtitle = "google";         string actualtitle = "";  // launch ie , direct base url         driver.get(baseurl);           // actual value of title         actualtitle = driver.gettitle();         /*          * compare actual title of page witht expected 1 , print          * result "passed" or "failed"          */        if (actualtitle.contentequals(expectedtitle)){             system.out.println("test passed!");         } else {             system.out.println("test failed");         }      //close firefox         driver.close();                  // exit program explicitly         system.exit(0);  } }

when run following exception.

    started internetexplorerdriver server (64-bit) 2.42.0.0 listening on port 42229 exception in thread "main" java.lang.nullpointerexception         @ org.openqa.selenium.remote.remotewebdriver.execute(remotewebdriver.java:600)         @ org.openqa.selenium.remote.remotewebdriver.startsession(remotewebdriver.java:241)         @ org.openqa.selenium.remote.remotewebdriver.startsession(remotewebdriver.java:226)         @ org.openqa.selenium.ie.internetexplorerdriver.run(internetexplorerdriver.java:182)         @ org.openqa.selenium.ie.internetexplorerdriver.<init>(internetexplorerdriver.java:174)         @ org.openqa.selenium.ie.internetexplorerdriver.<init>(internetexplorerdriver.java:146)         @ mypackage.myclass.main(myclass.java:15)

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
