How to retry failed test specs in protractor jasmine

问题

I am trying to use protractor-retry mechanism to run my protractor e2e tests. I have installed Protractor-retry package and added required things in conf.js file as below:

var PropertiesReader = require('properties-reader');
var properties = PropertiesReader('config.properties');
var retry = require('protractor-retry').retry;
exports.config = {

plugins: [{
    package: 'jasmine2-protractor-utils',
    disableHTMLReport: false,
    disableScreenshot: false,
    //screenshotPath: './reports/screenshots',
    screenshotPath: './ExecutionResults/reports/screenshots',
    screenshotOnExpectFailure: true,
    screenshotOnSpecFailure: true,
    clearFoldersBeforeTest: true,
    htmlReportDir: './reports/htmlReports',
    failTestOnErrorLog: {
        failTestOnErrorLogLevel: 1100,
        excludeKeywords: ['keyword1', 'keyword2']
    }
}],
directConnect: true,
// Capabilities to be passed to the webdriver instance.
multiCapabilities: [
    {
        'browserName': properties.get('browserName'),
    }],

    onCleanUp: function(results) {
        retry.onCleanUp(results);
    },
suites: {
        test: '../test_spec/smoke/cards/test.js'
},

// Options to be passed to Jasmine.
allScriptsTimeout: properties.get('allscriptTimeOutSeconds'),
getPageTimeout: properties.get('pageTimeOut'),
jasmineNodeOpts: {
    defaultTimeoutInterval: 2000000
},
onPrepare: function () {
    retry.onPrepare();
    var jasmineReporters = require('jasmine-reporters');
    var width = 1400;
    var height = 1000;
    browser.driver.manage().window().maximize();
    useAllAngular2AppRoots: true,
    browser.driver.get(properties.get('envUrl'),);
    browser.driver.manage().timeouts().implicitlyWait(10000);

    var AllureReporter = require('jasmine-allure-reporter');
    jasmine.getEnv().addReporter(new AllureReporter({
        allureReport: {
            resultsDir: 'allure-results'
        }
    }));

    jasmine.getEnv().addReporter(new jasmineReporters.JUnitXmlReporter({
        consolidateAll: true,
        savePath: 'testresults',
        filePrefix: 'xmloutput'
    }));
    var junitReporter = new jasmineReporters.JUnitXmlReporter({
        // setup the output path for the junit reports
        savePath: 'output/',
        consolidateAll: false
    });
    jasmine.getEnv().addReporter(junitReporter);
    return global.browser.getProcessedConfig().then(function (config) { });
},
afterLaunch: function() {
    return retry.afterLaunch(2);
 },

onComplete: function () {
    var browserName, browserVersion;
    var capsPromise = browser.getCapabilities();

    capsPromise.then(function (caps) {
        browserName = caps.get('browserName');
        browserVersion = caps.get('version');

        var HTMLReport = require('protractor-html-reporter');

        testConfig = {
            reportTitle: 'Test Execution Report',
            outputPath: './ExecutionResults/reports',
            screenshotPath: './screenshots',
            testBrowser: browserName,
            browserVersion: browserVersion,
            modifiedSuiteName: false,
            screenshotsOnlyOnFailure: true
        };
        browser.sleep(5000)
        new HTMLReport().from('testresults/xmloutput.xml', testConfig);
        browser.close();
    });
}
};

My test file is as below:

describe("Timesheet_Apply_Approved_Card", function () {
it ("Retest 1." , function(){
    //browser.get("http://www.google.com")
    //  browser.sleep(3000)
    console.log("test var : "+ testing.label)
    console.log("test " + testing._exitReasonFamilyReason)
       console.log("after test")
    expect("a").toEqual("b")
})


it ("Restest 2." , function(){
    console.log("after test 2")
    expect("a").toEqual("a")
})
})

But when I run the above test.js file. It does not run the failed test again.It gives below error:

test var : undefined
test undefined
inside method undefined
after test
Fafter test 2
.

Failures:
1) Timesheet_Apply_Approved_Card Retest 1.
Message:
Expected 'a' to equal 'b'.
Stack:
Error: Failed expectation

[17:43:43] E/launcher - Process exited with error code 199

It prints that it is trying again but than abruptly fails with error as given above.

Any idea, why it is failing without retrying?

Look Like you are running your CMD from a windows laptop/server, which is not supported by this protractor-retry pkg
