• ✅ Test Templates - Pre-built test patterns for common scenarios
• ✅ Quick Snippets - Insert common test code blocks
• ✅ Real-time Execution - Execute test scripts against response data
• ✅ Detailed Results - Pass/fail status with error messages
• ✅ Console Output - Capture and display console.log output
• ✅ Script Persistence - Auto-save test scripts to localStorage

Test Script Features:

• Status Code Validation: Check response status codes
• JSON Schema Validation: Validate response structure and data types
• Response Time Testing: Performance assertions
• Header Validation: Check presence and values of response headers
• Data Validation: Complex assertions on response data
• Custom Assertions: Full expect/chai-style assertion library
• Error Reporting: Detailed error messages with context

Available Test APIs:

// Status checks
pm.response.to.have.status(200);

// JSON data access
const jsonData = pm.response.json();

// Response time checks
pm.expect(pm.response.responseTime).to.be.below(200);

// Header validation
pm.response.to.have.header("Content-Type");

// Data validation with chaining
pm.expect(jsonData).to.have.property('id').that.is.a('number');
pm.expect(jsonData.email).that.matches(/^[^\s@]+@[^\s@]+\.[^\s@]+$/);
