protractor-jasmine2-html-reporter doesn't cons

问题:

Recently we have configured our e2e-tests to be on Jenkins & soon we realized that we have to use shared test files: true options as complete suite run is taking very long time for us peeking 9-10hrs on daily basis. but when we configured below two options in conf file. tests are running fine but final report displays only the last specs run results in save path. consolidate all options is not giving the full reports.

please find our conf file details. any help will be appreciated.

Edit the conf file as per solution provide by Aditya. please help

The limitation is with the 'Jasmine2HtmlReporter' as it overwrites the html report file when tests run in parallel. But avoiding this is definitely possible and there are couple of ways of doing it. Pick up the right way based on your convenience

1) Tinker with 'index.js' of Jasmine2HtmlReporter to append file instead of PhantomJs overwrite its using

2) Generate unique HTML reports by configuring Jasmine2HTML reporter from onPrepare() function and consolidate all the reports later

SOLUTION 1: The current code base of Jasmine2HtmlReporter - index.js uses two functions - phantomWrite() & nodeWrite() to write data. Refer here

I have created a new function - appendwrite() to append instead of overwriting and have modified code to pickup this function Check out my github code forked out of protractor-jasmine2-html-reporter

        function appendwrite(path, filename, text){
            var fs = require("fs");
            var nodejs_path = require("path");
            require("mkdirp").sync(path); // make sure the path exists
            var filepath = nodejs_path.join(path, filename);
            fs.appendFileSync(filepath,text)
            return;
        }

And modify the self.writeFile function in 'node_modules/protractor-jasmine2-html-reporter/index.js' to pickup the new function

        try {
            appendwrite(path, filename, text);
            //phantomWrite(path, filename, text);
            return;
        } catch (e) { errors.push('  PhantomJs attempt: ' + e.message); }
        try {
            nodeWrite(path, filename, text);
            return;
        } catch (f) { errors.push('  NodeJS attempt: ' + f.message); }

And Comment the below code which cleans reports on new run so that you dont see any error cleanup error - CleanUpCode

    rmdir(self.savePath);

SOLUTION 2: Generate separate reports based on sessionID for parallel instances by configuring the Jasmine reporter in OnPrepare function

onPrepare: function() {
        return new Promise(function (fulfill, reject) {
            browser.getCapabilities().then(function (value) {
                reportName = value.get('webdriver.remote.sessionid') + '_' + value.get('browserName') + '_' + Math.floor(Math.random()*1E16);
                jasmine.getEnv().addReporter(
                    new Jasmine2HtmlReporter({
                        savePath: 'target/',
                        screenshotsFolder: 'images',
                        consolidate: true,
                        consolidateAll: true,
                        filePrefix: reportName + ".html"
                    })
                );
                fulfill();
            })
        });
    },

Step 2: Consolidate the reports generated across parallel instances in afterLaunch() method after complete tests are done and all webdriver sessions are closed

afterLaunch: function afterLaunch() {
        var fs = require('fs');
        var output = '';
       fs.readdirSync('target/').forEach(function(file){
           if(!(fs.lstatSync('target/' + file).isDirectory()))
            output = output + fs.readFileSync('target/' + file);
       });
        fs.writeFileSync('target/ConsolidatedReport.html', output, 'utf8');
    },

You will see reports generated something like below with one ConsolidatedReport also PS: Please ignore any typo and syntax errors. this is just to serve as an example and can be customized

EDIT1: The 'sessionID' we are using to name the HTML report is the webdriver remote sessionID and if you have doubt that it may not remain unique through multiple sessions, Just generate a random number for the individual HTML reports and consolidate later

I have modified the code above

I am currently struggling with the same problem, however in my prototype setup it IS working, and I am using the BASE config, and nothing more.

var Jasmine2HtmlReporter = require('protractor-jasmine2-html-reporter');


exports.config = {
framework: 'jasmine',
seleniumAddress: 'http://localhost:4444/wd/hub',
specs: ['**-spec**.js'],

capabilities: {
    browserName: 'chrome',                                                      
    shardTestFiles: true,                                                        
    maxInstances: 2                                                             
},

onPrepare: function() {
    jasmine.getEnv().addReporter(
      new Jasmine2HtmlReporter({
        savePath: 'target/',
        screenshotsFolder: 'images',
        consolidate: true,
        consolidateAll: false  // false in my saved config - true in tut.
    })
  );
}
}

Can you see if you can get shard reporting working with just the bare minimum ?

Edit : Also keep a eye on what is happening in the target folder, Jasmine might be overwriting/cleaning when you dont want it.

Edit 2: if you go for the solution below me, make sure you are launching enough browsers as you have specs - the solution below me makes reports based on browser ID, if you split your specs :

capabilities: {
    browserName: 'chrome',                                                      
    shardTestFiles: true,                                                       
    maxInstances: **2**                                                             
},

it will still overwrite your reporter HTML if you want more than 2. It creates a HTML file based on the browser/session ID used to test it - If you use 2 browsers instances you will get 2 HTML files, no more no less.

Edit 3 : A quick fix would be to not let jasmine clean up...

cleanDestination: false,

But this does not seem to do anything, so after searching and searching - I do not think the jasmine html reporter is going to let us consolidate more specs than we have shards. Issue tracker on github is not showing any progress.

So the only solution I can think of, is to use the solution below me, with enough shards to support your ammount of specs, and then parse it back to one file when your done.

Edit 4: You can always abuse Jenkins to concate the HTML files between actual test runs.

Solution from Aditya works fine for me. My example config file: var Jasmine2HtmlReporter = require('protractor-jasmine2-html-reporter');

exports.config = { framework: 'jasmine2', seleniumAddress: 'http://localhost:4444/wd/hub', /multiCapabilities: [ { 'browserName': 'chrome', 'shardTestFiles': true, 'maxInstances': 2, chromeOptions: { args: ['chrome.switches', '--disable-extensions'] } }, { 'browserName': 'firefox' } ],/ capabilities: { 'browserName': 'chrome', 'shardTestFiles': true, 'maxInstances': 2, chromeOptions: { args: ['chrome.switches', '--disable-extensions'] } }, suites: { loginpage: 'login.js', addproduct: 'addproduct.js' }, //specs: ['addproduct.js'], jasmineNodeOpts: { onComplete: null, isVerbose: false, includeStackTrace: true, showColors: true, defaultTimeoutInterval: 30000 },

onPrepare: function() {
    return new Promise(function(fulfill, reject) {
        browser.getCapabilities().then(function(value) {
            reportName = value.get(Math.random(8,2)) + '_' + value.get('browserName') + '_' + Math.floor(Math.random() * 1E16);
            jasmine.getEnv().addReporter(
                new Jasmine2HtmlReporter({
                    //cleanDestination: false,
                    savePath: 'target/',
                    //docTitle: 'Web UI Test Report',
                    screenshotsFolder: 'image',
                    //takeScreenshots: true,
                    //takeScreenshotsOnlyOnFailures: true,
                    consolidate: true,
                    consolidateAll: true,
                   // preserveDirectory: true,
                    //fixedScreenshotName: true,
                    filePrefix: reportName + ".html"
                })
            );
            fulfill();
        });
    });
},
afterLaunch: function afterLaunch() {
    var fs = require('fs');
    var output = '';
    fs.readdirSync('target/').forEach(function(file) {
        if (!(fs.lstatSync('target/' + file).isDirectory()))
            output = output + fs.readFileSync('target/' + file);
    });
    fs.writeFileSync('target/ConsolidatedReport.html', output, 'utf8');
}

}

I used below solution to create unique folder with unique timestamp. This will save HTML report in date-timestamp folder instead Jasmin-2-html-reporter deleting it.

var today = new Date();
   var timeStamp = today.getMonth() + 1 + '-' + today.getDate() + '-' + today.getFullYear() + '-' + 

today.getHours() + 'h-' + today.getMinutes() + 'm-' +today.getSeconds()+'s';

 jasmine.getEnv().addReporter(
            new Jasmine2HtmlReporter({
                savePath: './Reports/testResultsReport '+timeStamp,
                screenshotsFolder: 'screenPrints',
                takeScreenshots: true,
                takeScreenshotsOnlyOnFailures: true,
            })
        );
