Test Script Examples
// Status code test
pm.test('Status is 200', function() {
pm.response.to.have.status(200);
});
// Response time test
pm.test('Response time < 200ms', function() {
pm.expect(pm.response.responseTime).to.be.below(200);
});
// JSON validation
pm.test('Has user property', function() {
const data = pm.response.json();
pm.expect(data).to.have.property('user');
});
// Set environment variable
pm.environment.set('token', pm.response.json().token);Best Practices
- Use environment variables for different stages
- Write tests for all API endpoints
- Organize requests into collections
- Use pre-request scripts for dynamic data
