💡 Hint

Common Mistakes

Using 'update' instead of 'install' will not install the package if it's missing.

Using 'remove' will uninstall the package, not install it.

The correct command to install Newman globally is npm install -g newman. The install keyword tells npm to add the package.

💡 Hint

Common Mistakes

Using 'run' will try to execute a collection, not show version.

Using 'install' or 'update' are npm commands, not Newman flags.

To check the version of Newman installed, use newman --version. This shows the current version number.

💡 Hint

Common Mistakes

Including '-g' installs globally, not locally.

Using 'update' or 'remove' will not install the package.

To install Newman locally (in the current project), use npm install newman. The -g flag is for global installs and should be omitted here.

Fill both blanks to run a Postman collection file named 'test_collection.json' using Newman.

💡 Hint

Common Mistakes

Using '--version' instead of 'run' will only show version info.

Using '-g' is for global npm installs, not Newman run commands.

The correct command is newman run test_collection.json -r. The run keyword tells Newman to execute the collection, and -r specifies reporters.

5fill in blank

Fill all three blanks to install Newman globally and verify its version.

Postman

npm [1] -g newman && newman [2] && newman [3]

Drag options to blanks, or click blank then click option'

B--version

Crun

💡 Hint

Common Mistakes

Using 'update' instead of 'install' will not install if missing.

Using 'run' in the second blank will not show version info.

The full command is npm install -g newman && newman --version && newman run. This installs Newman globally, checks its version, and runs a collection (which you would specify after 'run').

Practice

1. What is the primary purpose of Newman in relation to Postman?

easy

A. To run Postman tests from the command line

B. To create Postman collections

C. To design API endpoints

D. To generate API documentation

Solution

1. Step 1: Understand Newman's role

   Newman is a command-line tool that executes Postman collections outside the Postman app.

2. Step 2: Identify the correct purpose

   Among the options, only running tests from the command line matches Newman's function.

3. Final Answer:

   To run Postman tests from the command line -> Option A

4. Quick Check:

   Newman runs tests = D [OK]

Hint: Newman runs tests outside Postman app [OK]

Common Mistakes:

• Confusing Newman with Postman GUI features
• Thinking Newman creates API endpoints
• Assuming Newman generates documentation

2. Which command correctly installs Newman globally using npm?

easy

A. npm install newman

B. npm install -g newman

C. npm newman install -g

D. install npm -g newman

Solution

1. Step 1: Recall npm global install syntax

   The correct syntax to install a package globally is npm install -g package-name.

2. Step 2: Match the command with Newman

   npm install -g newman matches this syntax exactly for Newman.

3. Final Answer:

   npm install -g newman -> Option B

4. Quick Check:

   Global install uses -g flag = B [OK]

Hint: Global install needs -g flag after install [OK]

Common Mistakes:

• Omitting the -g flag for global install
• Incorrect command word order
• Using 'install npm' instead of 'npm install'

3. After installing Newman globally, what will be the output of the command newman --version if Newman version 5.3.0 is installed?

medium

A. v5.3.0

B. newman version 5.3.0

C. Newman 5.3.0

D. 5.3.0

Solution

1. Step 1: Understand typical npm package version output

   Most npm CLI tools output version without a 'v' prefix, like '5.3.0'. Newman outputs the version number without the 'v'.

2. Step 2: Match expected output format

   Among the options, only '5.3.0' matches the actual output of newman --version.

3. Final Answer:

   5.3.0 -> Option D

4. Quick Check:

   Newman version output does not include 'v' prefix = B [OK]

Hint: Newman version command outputs version without 'v' prefix [OK]

Common Mistakes:

• Expecting full text like 'newman version'
• Assuming 'v' prefix is included
• Confusing output with other commands

4. You ran npm install -g newman but get a 'command not found' error when typing newman --version. What is the most likely cause?

medium

A. The system PATH does not include npm global binaries

B. Node.js is not installed

C. npm cache is corrupted

D. Newman was not installed globally

Solution

1. Step 1: Understand the error context

   The 'command not found' error means the shell cannot find the Newman executable.

2. Step 2: Identify common causes

   Even if Newman is installed globally, if the system PATH does not include npm global binaries folder, the command won't be found.

3. Final Answer:

   The system PATH does not include npm global binaries -> Option A

4. Quick Check:

   PATH missing npm binaries causes command not found [OK]

Hint: Check PATH includes npm global bin folder [OK]

Common Mistakes:

• Assuming Newman was not installed without checking PATH
• Ignoring Node.js installation status
• Blaming npm cache without evidence

5. You want to run a Postman collection named api-tests.postman_collection.json using Newman after installation. Which command correctly runs the collection and saves the report to report.json?

hard

A. newman run api-tests.postman_collection.json -r json > report.json

B. newman api-tests.postman_collection.json --report json --output report.json

C. newman run api-tests.postman_collection.json --reporters json --reporter-json-export report.json

D. newman run api-tests.postman_collection.json --save-report report.json

Solution

1. Step 1: Recall Newman run command syntax

   The correct syntax to run a collection is newman run <collection-file>.

2. Step 2: Identify correct reporter options

   To save a JSON report, use --reporters json --reporter-json-export <file>.

3. Step 3: Match the correct option

   newman run api-tests.postman_collection.json --reporters json --reporter-json-export report.json uses the correct command and reporter flags to save the report as report.json.

4. Final Answer:

   newman run api-tests.postman_collection.json --reporters json --reporter-json-export report.json -> Option C

5. Quick Check:

   Use --reporters and --reporter-json-export for JSON report [OK]

Hint: Use --reporters and --reporter-json-export flags [OK]

Common Mistakes:

• Using shell redirection instead of reporter flags
• Omitting 'run' keyword
• Using incorrect or unsupported flags
