Unable to parse cucumberjs output into json - error while generating the report with Cucumber-html-reporter

[ravim20051]

I am trying to execute the test in Protractor and generate the results in JSON format and integrationg Cucumber-html-reporter to take this JSON as input and generate the HTML report with Bootstrap options. But Not sucessfull

Below is my config file:

var reporter = require('cucumber-html-reporter'); exports.config = { seleniumAddress: 'http://172.17.205.173:4444/wd/hub', seleniumSessionId: '1bcc031df0fa1a241b0fd06445af324d',

capabilities: { 'browserName': 'chrome' },

specs: ['Login_ZRPE.js'], resultJsonOutputFile:'G:/Protractor/ZPlatform_Script/protractor-reports/cucumber_report.json',

onComplete: function() { var options = { theme: 'bootstrap', jsonFile: 'G:/Protractor/ZPlatform_Script/protractor-reports/cucumber_report.json',
output: 'G:/Protractor/ZPlatform_Script/protractor-reports/cucumber_report.html', reportSuiteAsScenarios: true, launchReport: true, metadata: { "App Version":"0.3.2", "Test Environment": "STAGING", "Browser": "Chrome 54.0.2840.98", "Platform": "Windows 10", "Parallel": "Scenarios", "Executed": "Remote" } }; reporter.generate(options); } };

Execute the above config file, Test executed successfully but while report generation the below error is displays. I have tried various options which is available in various forum but the below is not resolved. Please let me know how to solve this issue

Interesting, ok. Do you have a copy oft he JSON it rendered? If you could send that, I can try to run locally to.

Also, can you use a relative path to see if it works? Instead of:

G:/Protractor/ZPlatform_Script/protractor-reports/cucumber_report.json

Try:

./cucumber_report.json

I am also facing same issue.

Protractor.config.js

const path = require('path'); const argv = require('yargs').argv; const Reporter = require('./e2e/support/reporter'); // const jsonReports = process.cwd() + '/reports/json'; const jsonReports = path.join(process.cwd(), "/reports/json");

I am also getting the same issue:

Unable to parse cucumberjs output into json: 'reports/cucumber-report.json' SyntaxError: reports/cucumber-report.json: Unexpected end of JSON input.

Please help me to resolve this issue.

Any solution to this problem? I am using cucumber-html-reporter too and stuck with this issue " Unable to parse cucumberjs output into json: '\e2e\reports\json\cucumber_report.json' { Error: \e2e\reports\json\cucumber_report.json: ENOENT: no such file or directory, open '\e2e\reports\json\cucumber_report.json'

I am facing the same issue. The thing which I could figure out from this is. Till the time we are expecting the html-reporter to read the updated report.json file and generate an Html report out of it, the cucumber-js process has not finished writing the test report. And hence, it fails to parse the file.

In my case, I am calling the report generation utility in Afterall hook. And running the tests in parallel. However, when I run the test in a single thread. Then this works fine and generates the report at the end of the execution

Update the options to use html format, it should work

let options = [ '--require-module ts-node/register', '--require ./steps/stepDef.steps.ts', '--format progress', '--format html:Reports/report.html', '--format json:Reports/report.json' ].join(' ');
