Challenge - 5 Problems

What is the output format of the default Postman CLI reporter?

When running Postman tests via CLI, what is the default format of the test report output?

Postman

newman run collection.json

A A simple text summary printed in the terminal

B A JSON file with all test results

C A JUnit XML file generated automatically

D A detailed HTML report saved to disk

💡 Hint

Think about what you see immediately after running tests in terminal

By default, Newman (Postman's CLI tool) outputs a simple text summary directly in the terminal, showing passed and failed tests.

Which reporter option generates a detailed interactive report in Postman?

You want to generate a detailed, interactive report with charts and test details after running Postman tests. Which reporter option should you use?

A JSON reporter

B JUnit reporter

C CLI reporter

D HTML reporter

💡 Hint

Think about which format is best for viewing in a browser

The HTML reporter generates a detailed interactive report viewable in a browser with charts and test details.

❓ assertion

advanced

Which assertion correctly checks if a JUnit report file was generated after running Newman with JUnit reporter?

You run Newman with the JUnit reporter option. Which assertion correctly verifies the JUnit XML report file exists?

Postman

const fs = require('fs');
const reportPath = './newman/results.xml';
// Assertion here

A assert(fs.existsSync(reportPath), 'JUnit report file should exist');

B assert(fs.readFileSync(reportPath), 'JUnit report file should exist');

C assert(fs.exists(reportPath), 'JUnit report file should exist');

D assert(fs.fileExists(reportPath), 'JUnit report file should exist');

💡 Hint

Check Node.js fs module methods for checking file existence

fs.existsSync(path) returns true if the file exists synchronously. Other options are invalid or asynchronous.

🔧 Debug

advanced

Why does the HTML reporter not generate a report file when running Newman with this command?

You run: newman run collection.json --reporters cli,html But no HTML report file is created. What is the likely cause?

A The CLI reporter disables HTML report generation

B The HTML reporter is not supported in Newman

C You forgot to specify the output file path with --reporter-html-export

D You need to install a separate package for HTML reports

💡 Hint

Check how to specify output file for HTML reporter

The HTML reporter requires an explicit output file path using --reporter-html-export option to save the report.

How to configure multiple reporters in Newman programmatically to generate CLI, HTML, and JUnit reports?

You want to run Newman tests from a Node.js script and generate CLI output, an HTML report saved as 'report.html', and a JUnit report saved as 'results.xml'. Which code snippet correctly configures this?

Postman

const newman = require('newman');

newman.run({
  collection: require('./collection.json'),
  reporters: [...],
  reporter: {
    html: { export: '...' },
    junit: { export: '...' }
  }
}, function (err) {
  if (err) { throw err; }
  console.log('Run complete!');
});

A reporters: ['cli', 'html', 'junit'], reporter: { html: 'report.html', junit: 'results.xml' }

B reporters: ['cli', 'html', 'junit'], reporter: { html: { export: 'report.html' }, junit: { export: 'results.xml' } }

C reporters: ['cli', 'html', 'junit'], reporter: { html: { path: 'report.html' }, junit: { path: 'results.xml' } }

D reporters: ['cli', 'html', 'junit'], reporter: { html: { file: 'report.html' }, junit: { file: 'results.xml' } }

💡 Hint

Check Newman reporter options object structure in documentation

The reporter options use 'export' key to specify output file paths for HTML and JUnit reporters.
