How to get 'cfg' in preScript function?

[iwiszhou]

Hi,

How can I access to 'cfg' object inside the preScript function ? (https://github.com/axemclion/browser-perf/wiki/Node-Module---API#prescript )

\ Example ** Here is the simple options object I created.

var options = { selenium: 'http://localhost:4444/wd/hub', browsers: ['chrome'], preScript: function(browser) { return browser.get(cfg.page).then(function() { console.log('Find sign in in discover'); return browser.elementByCssSelector('.signin-btn') }).then(function(el) { console.log('Clicking sign in'); return el.click(); }); } }

Looks like that was an error in the documentation. I fixed it now. You cannot call cdf obkect. Since this is a script that you write, you could refer to it in your script, without really needing a cfg object.

for the new documentation, "browser.get('www.example.com')". However, how can I reference back the website I defined in browserPerf function. I think we should browser.get( the site we passed in browserPerf function) ?

browserPerf('http://mysite.com', function(err, res) { // res - array of objects. Metrics for this URL if (err) { console.log('ERROR: ' + err); } else { console.log(res); } }, options);

Can those not be saved in a variable and passed in at the two places ?

Hum...that may be not the case I want to test.

Let's say I have 2 page. Page 1 just introduction about my site. Page 2 is a login page with "Login" button. In page 1, there is a button "GO TO PAGE 2" will navigate user to Page 2, and login into the system.

Okay, now I want to test the button click "GO TO PAGE 2", then click "Login" button on Page 2.

If I called browser.get("http://mysite.com"), it seems it will navigate to http://mysite.com again, and execute all those button click actions. and when that one is done. It will go back to http://mysite.com again.

Problem is here. It should not navigate back to http://mysite.com when preScript is finished. It may caused by we called browser.get("http://mysite.com") which is not same instance when browserPerf( "browserPerf", ....).

In this specific case, you can pass null as the URL to browserPerf(null, {}). This way, the only navigation will be on the preScript. Once the preScript is finished, there is no navigation.

I just tried. I got the following error..

ERROR PRINT OUT IN CONSOLE: ERROR: Error: [get("perf")] Error response status: 13, UnknownError - An unknown server-side error occurred while processing the command.

CODE:

var browserPerf = require('browser-perf'); var testWebSitUrl = 'http://www.mysite.com'; var options = { selenium: 'http://localhost:4444/wd/hub', browsers: ['chrome'], preScript: function(browser) { return browser.get(testWebSitUrl).then(function() { console.log('Find sign in in discover'); return browser.elementByCssSelector('.signin-btn') }).then(function(el) { console.log('Clicking sign in'); return el.click(); }); } } browserPerf('perf', function(err, res) { // res - array of objects. Metrics for this URL if (err) { console.log('ERROR: ' + err); } else { console.log("result ----> "); console.log(res); } }, options);

[axemclion]

The URL passed should be null. This code works

var browserPerf = require('browser-perf');
var testWebSitUrl = 'http://www.google.com';
var options = {
    selenium: 'http://localhost:9515',
    browsers: ['chrome'],
    preScript: function (browser) {
        return browser.get(testWebSitUrl).then(function () {
            console.log('Find sign in in discover');
            return browser.elementByCssSelector('.signin-btn')
        }).then(function (el) {
            console.log('Clicking sign in');
            return el.click();
        });
    }
}
browserPerf(null, function (err, res) {
    // res - array of objects. Metrics for this URL
    if (err) {
        console.log('ERROR: ' + err);
    } else {
        console.log("result ----> ");
        console.log(res);
    }
}, options);

Do you mind to add an "browserPerf.actions.login" example for perScript?

I tried using it inside the perScript without any luck....

I tried something like, no sure it is the correct approach.... preScript: function(browser) { return browser.get(testWebSitUrl).then(function() { console.log('Find sign in in mysite'); return browser.elementByCssSelector('.signin-btn') }) .then(function(el) { console.log('Clicking sign in'); return el.click(); }) .then(function(){ browserPerf.actions.login({ username: { field: 'form>ul>li:first-child>input', value: 'username' }, password: { field: 'form>ul>li:2th-child>input', value: 'password' }, submit:{ field: 'form>ul>li:3th-child>input' } }) })
