terminal Installation & Usage
# Install Newman globally
npm install -g newman
# Run a collection
newman run my-collection.json -e my-environment.json
# Run with environment variables
newman run my-collection.json --env-var "baseUrl=https://api.example.com"
# Generate HTML report
newman run my-collection.json --reporters html --reporter-html-export report.html// Postman test script for an API endpoint
// Run after a request is made
// Check status code
pm.test("Status code is 200", () => {
pm.response.to.have.status(200);
});
// Validate response body
pm.test("Response has user data", () => {
const jsonData = pm.response.json();
pm.expect(jsonData).to.have.property('id');
pm.expect(jsonData).to.have.property('email');
});
// Validate response time
pm.test("Response time is less than 500ms", () => {
pm.expect(pm.response.responseTime).to.be.below(500);
});
// Check headers
pm.test("Content-Type is JSON", () => {
pm.response.to.have.header('Content-Type');
pm.expect(pm.response.headers.get('Content-Type'))
.to.include('application/json');
});
// Save response data to environment variable
const jsonData = pm.response.json();
pm.environment.set('userId', jsonData.id);history Version History
