Automated Test Framework (ATF)

Overview

The Automated Test Framework (ATF) is ServiceNow's native testing solution for validating platform functionality. This skill covers:

• Creating test suites and organizing tests
• Building tests with various step types (Server, Client, UI)
• Writing assertions and validations
• Managing test data setup and cleanup
• Implementing parameterized tests
• Running tests manually and on schedule
• Analyzing test results and failures
• Integrating ATF with CI/CD pipelines
• Best practices for maintainable, reliable tests

When to use: Before deploying changes to production, during development (TDD), after upgrades, and as part of regression testing.

Who should use this: Developers, QA engineers, and administrators who need to ensure platform reliability.

Prerequisites

• Roles: atf_test_admin (full access) or atf_test_designer (create/edit tests)
• Plugins: Automated Test Framework (com.snc.automated_testing)
• Access: sys_atf_test, sys_atf_test_suite, sys_atf_step tables
• Knowledge: Basic understanding of ServiceNow scripting (GlideRecord, client scripts)
• Related Skills: admin/script-execution, admin/update-set-management

      script: |
        // Complex assertion logic
        var testPassed = true;
        var messages = [];

        // Get the incident
        var gr = new GlideRecord('incident');
        gr.get('${inserted_incident.sys_id}');

        // Assertion 1: State validation
        if (gr.state != 2) {
          testPassed = false;
          messages.push('Expected state 2, got ' + gr.state);

Phase 9: CI/CD Integration

Step 9.1: REST API for CI/CD

ServiceNow provides REST APIs for ATF integration.

Start Test Suite via REST:

POST /api/sn_cicd/testsuite/run
Content-Type: application/json

{
  "test_suite_sys_id": "[suite_sys_id]",
  "browser_name": "Chrome",
  "browser_version": "latest"
}

Check Test Progress:

GET /api/sn_cicd/progress/[result_id]

Get Test Results:

GET /api/sn_cicd/testsuite/results/[result_id]

Step 9.2: Integration with Jenkins

Jenkins Pipeline Example:

pipeline {
  agent any

  environment {
    SN_INSTANCE = 'https://dev123.service-now.com'
    SN_CREDENTIALS = credentials('servicenow-api')
  }

  stages {
    stage('Run ATF Tests') {
      steps {
        script {
          // Start test suite
          def response = httpRequest(
            url: "${SN_INSTANCE}/api/sn_cicd/testsuite/run",
            httpMode: 'POST',
            authentication: 'servicenow-api',
            contentType: 'APPLICATION_JSON',
            requestBody: """
              {
                "test_suite_sys_id": "${params.TEST_SUITE_ID}",
                "browser_name": "Chrome"
              }
            """
          )

          def result = readJSON text: response.content
          env.RESULT_ID = result.result.sys_id
        }
      }
    }

    stage('Wait for Results') {
      steps {
        script {
          def status = 'running'
          while (status == 'running') {
            sleep 30
            def response = httpRequest(
              url: "${SN_INSTANCE}/api/sn_cicd/progress/${env.RESULT_ID}",
              authentication: 'servicenow-api'
            )
            def progress = readJSON text: response.content
            status = progress.result.status
          }
        }
      }
    }

    stage('Evaluate Results') {
      steps {
        script {
          def response = httpRequest(
            url: "${SN_INSTANCE}/api/sn_cicd/testsuite/results/${env.RESULT_ID}",
            authentication: 'servicenow-api'
          )
          def results = readJSON text: response.content

          if (results.result.status != 'success') {
            error "ATF tests failed: ${results.result.fail_count} failures"
          }
        }
      }
    }
  }
}

Step 9.3: Integration with GitHub Actions

GitHub Actions Workflow:

name: ServiceNow ATF Tests

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  atf-tests:
    runs-on: ubuntu-latest

    steps:
      - name: Run ATF Test Suite
        id: run-tests
        run: |
          RESPONSE=$(curl -s -X POST \
            -u "${{ secrets.SN_USERNAME }}:${{ secrets.SN_PASSWORD }}" \
            -H "Content-Type: application/json" \

          if [ "$STATUS" != "success" ]; then
            echo "::error::ATF tests failed"
            exit 1
          fi

Phase 10: Advanced Patterns

Step 10.1: Page Object Pattern for UI Tests

Create reusable step configurations for common UI operations.

Query Available Step Configs:

Tool: SN-Query-Table
Parameters:
  table_name: sys_atf_step_config
  query: active=true
  fields: sys_id,name,category,description
  limit: 100

Common Step Configs:

Category	Step Config	Purpose
Record	Record - Insert	Create new record
Record	Record - Query	Find existing record
Record	Record - Update	Modify record
Record	Record - Delete	Remove record
Form	Open a new form	Navigate to new form
Form	Open an existing record	Navigate to record
Form	Set field value	Populate field
Form	Click a button	Trigger button action
Assertion	Verify field value	Assert field content
Script	Run Server Side Script	Execute custom logic

Step 10.2: Test Data Factory Pattern

Create a script include for generating test data.

Using MCP:

Tool: SN-Create-Record
Parameters:
  table_name: sys_script_include
  data:
    name: ATFTestDataFactory
    api_name: global.ATFTestDataFactory
    active: true
    client_callable: false
    description: "Factory for creating consistent ATF test data"
    script: |
      var ATFTestDataFactory = Class.create();
      ATFTestDataFactory.prototype = {

        initialize: function() {
          this.createdRecords = [];
        },

        createTestIncident: function(options) {
          options = options || {};

          var gr = new GlideRecord('incident');
          gr.initialize();
          gr.short_description = options.short_description ||
            'ATF Test Incident ' + gs.generateGUID().substring(0, 8);
          gr.description = options.description || 'Created by ATF Test';
          gr.priority = options.priority || 3;
          gr.category = options.category || 'software';
          gr.caller_id = options.caller_id || gs.getUserID();

          var sysId = gr.insert();
          this.createdRecords.push({ table: 'incident', sys_id: sysId });

          return sysId;
        },

        createTestUser: function(options) {
          options = options || {};
          var username = 'atf_' + gs.generateGUID().substring(0, 8);

          var gr = new GlideRecord('sys_user');
          gr.initialize();
          gr.user_name = options.user_name || username;
          gr.first_name = options.first_name || 'ATF';
          gr.last_name = options.last_name || 'User';
          gr.email = options.email || username + '@test.example.com';
          gr.active = true;

          var sysId = gr.insert();
          this.createdRecords.push({ table: 'sys_user', sys_id: sysId });

          return sysId;
        },

        createTestGroup: function(options) {
          options = options || {};

          var gr = new GlideRecord('sys_user_group');
          gr.initialize();
          gr.name = options.name || 'ATF Group ' + gs.generateGUID().substring(0, 8);
          gr.active = true;

          var sysId = gr.insert();
          this.createdRecords.push({ table: 'sys_user_group', sys_id: sysId });

          return sysId;
        },

        cleanup: function() {
          // Delete in reverse order to handle dependencies
          for (var i = this.createdRecords.length - 1; i >= 0; i--) {
            var record = this.createdRecords[i];
            var gr = new GlideRecord(record.table);
            if (gr.get(record.sys_id)) {
              gr.deleteRecord();
            }
          }
          this.createdRecords = [];
        },

        type: 'ATFTestDataFactory'
      };

Using Factory in Test:

Tool: SN-Create-Record
Parameters:
  table_name: sys_atf_step
  data:
    test: [test_sys_id]
    order: 10
    step_config: [run_script_config_sys_id]
    description: "Setup: Create test data using factory"
    inputs:
      script: |
        var factory = new ATFTestDataFactory();

        // Create test data
        outputs.incident_sys_id = factory.createTestIncident({
          priority: 1,
          short_description: 'Critical Server Issue'
        });

        outputs.user_sys_id = factory.createTestUser({
          first_name: 'Test',
          last_name: 'Admin'
        });

        // Store factory for cleanup
        outputs.factory = factory;

Step 10.3: Conditional Test Execution

Skip tests based on conditions.

Using MCP:

Tool: SN-Create-Record
Parameters:
  table_name: sys_atf_step
  data:
    test: [test_sys_id]
    order: 5
    step_config: [run_script_config_sys_id]
    description: "Pre-check: Verify test prerequisites"
    inputs:
      script: |
        // Check if required plugin is active
        var plugin = new GlideRecord('v_plugin');
        plugin.addQuery('id', 'com.snc.change_management');
        plugin.addQuery('state', 'active');
        plugin.query();

        if (!plugin.hasNext()) {
          // Skip this test if plugin not installed
          outputs.skip_test = true;
          outputs.skip_reason = 'Change Management plugin not active';

          // This will mark test as skipped, not failed
          stepResult.setStatus('skipped');
          stepResult.setMessage('Prerequisites not met: ' + outputs.skip_reason);
        }

Best Practices

Test Design

• Single Responsibility: Each test should validate one specific scenario
• Independence: Tests should not depend on other tests' execution order
• Isolation: Use unique test data to prevent conflicts with other tests
• Cleanup: Always clean up test data, even on test failure
• Naming: Use descriptive names: [Feature]_[Scenario]_[ExpectedResult]

Test Data

• Generate Unique Data: Use GUIDs or timestamps in test data names
• Avoid Production Data: Never reference real user data in tests
• Minimal Data: Create only the data needed for the test
• Data Factory Pattern: Use script includes for consistent data creation

Assertions

• Specific Assertions: Assert specific values, not just "not empty"
• Multiple Checks: Validate all critical aspects of the outcome
• Meaningful Messages: Include context in assertion failure messages
• Negative Testing: Test that invalid operations are correctly rejected

Performance

• Limit Queries: Use setLimit() and efficient queries
• Batch Operations: Group similar operations together
• Avoid UI Tests When Possible: Server-side tests are faster and more reliable
• Parallel Suites: Run independent test suites in parallel

Maintenance

• Version Control: Include tests in update sets
• Documentation: Add descriptions to tests and steps
• Refactoring: Update tests when requirements change
• Regular Execution: Run tests frequently to catch issues early

Troubleshooting

Test Fails to Start

Symptom: Test shows "Pending" status indefinitely Causes:

• ATF Runner not configured
• Missing test client for UI tests
• Test scheduler disabled Solution:

Tool: SN-Query-Table
Parameters:
  table_name: sys_atf_schedule
  query: active=true
  fields: sys_id,name,state,last_run

UI Tests Fail Randomly

Symptom: Same UI test passes and fails intermittently Causes:

• Timing issues with page load
• DOM changes between runs
• Browser version differences Solution:
• Add Wait steps before UI interactions
• Use stable element selectors
• Specify browser version in test configuration

Step Variables Not Resolved

Symptom: ${variable} appears literally in output Causes:

• Variable not set by previous step
• Typo in variable name
• Step order incorrect Solution:

Tool: SN-Query-Table
Parameters:
  table_name: sys_atf_variable
  query: test=[test_sys_id]
  fields: name,step,value

Test Data Not Cleaned Up

Symptom: Test data accumulates in instance Causes:

• Cleanup step not added
• Cleanup step failed before completing
• Test halted before cleanup Solution:
• Use try-finally pattern in cleanup scripts
• Create scheduled cleanup job for orphaned data:

Tool: SN-Execute-Background-Script
Parameters:
  script: |
    // Clean up orphaned ATF test data
    var tables = ['incident', 'sys_user', 'sys_user_group'];
    var cutoff = gs.daysAgo(1);  // Older than 1 day

    tables.forEach(function(table) {
      var gr = new GlideRecord(table);
      gr.addQuery('short_description', 'STARTSWITH', 'ATF');
      gr.addQuery('sys_created_on', '<', cutoff);
      gr.query();

      var count = 0;
      while (gr.next()) {
        gr.deleteRecord();
        count++;
      }

      if (count > 0) {
        gs.info('Cleaned up ' + count + ' orphaned records from ' + table);
      }
    });
  description: Clean orphaned ATF test data

CI/CD Pipeline Timeout

Symptom: Pipeline fails waiting for test completion Causes:

• Test suite takes too long
• ServiceNow instance performance issues
• Network connectivity problems Solution:
• Set appropriate timeout in pipeline
• Split large suites into smaller ones
• Use parallel test execution
