performance testing - How to test with jMeter against basic auth protected domain? -


i running staging cluster of apache/nginx webservers domain has basic authentication restricted access. goal test performance of cluster jmeter.

in order pass authentication have added http authentication controler of jmeter. works, every request shows 2 logentries @ apache. 1 200 , 1 401. normal behavior of first request user must authenticated. unfortunatelly, jmeter on every request.

how can make sure each thread/user requests access once. or better, how grant jmeter access without every user needing authenticat. believe impact test results.

thank hint on this.

it sounds jmeter bug given proper "authorization" header provided there shouldn't www-authenticate challenge. if file via jmeter bugzilla or flag via jmeter users mailing list great

in meantime can work around using 1 of following approaches:

  1. inject credentials directly url - in case of jmeter "path" input field like:

    http://username:password@host.domain/path

    basic auth 1 - credentials in url

  2. use beanshell scripting construct proper "authorization" header on-the-fly. in order so:

    • make sure http header manager present. if not - add on test plan level or child of http request needs authenticated
    • add beanshell preprocessor child of http request needs authenticated
    • provide username , password separated space via "parameters" input

    • put following code preprocessor's "script" area

      import org.apache.jmeter.protocol.http.util.base64encoder; import org.apache.jmeter.protocol.http.control.header;  string encodedcredentials = base64encoder.encode(bsh.args[0] + ":" + bsh.args[1]); sampler.getheadermanager().add(new header("authorization", "basic " + encodedcredentials));

    beanshell preprocessor - authentication

you shouldn't receiving 401 codes anywhere anymore.

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
