Creating Tests
Basic Test Structure (ES5)
// Create a new ATF test var test = new GlideRecord("sys_atf_test") test.initialize() test.setValue("name", "Test: Create High Priority Incident") test.setValue("description", "Verify high priority incident creation workflow") test.setValue("active", true) test.setValue("application", "global") // or scoped app sys_id var testSysId = test.insert()
// Add test steps function addTestStep(testId, order, stepType, config) { var step = new GlideRecord("sys_atf_step") step.initialize() step.setValue("test", testId) step.setValue("order", order) step.setValue("step_config", stepType)
// Set step-specific configuration for (var key in config) { if (config.hasOwnProperty(key)) { step.setValue(key, config[key]) } }
return step.insert() }
Impersonate Step
// Step 1: Impersonate ITIL user addTestStep(testSysId, 100, "sys_atf_step_config_impersonate", { description: "Impersonate ITIL user", inputs: JSON.stringify({ user: "itil", // or sys_id }), })
Open New Form Step
// Step 2: Open new incident form addTestStep(testSysId, 200, "sys_atf_step_config_open_new_form", { description: "Open new incident form", inputs: JSON.stringify({ table: "incident", }), })
Set Field Values Step
// Step 3: Set field values addTestStep(testSysId, 300, "sys_atf_step_config_set_field_values", { description: "Set incident fields", inputs: JSON.stringify({ table: "incident", values: [ { field: "short_description", value: "ATF Test Incident" }, { field: "priority", value: "1" }, { field: "category", value: "network" }, { field: "caller_id", value: "admin" }, ], }), })
Submit Form Step
// Step 4: Submit form (click Save) addTestStep(testSysId, 400, "sys_atf_step_config_click_ui_action", { description: "Save the incident", inputs: JSON.stringify({ ui_action: "sysverb_insert", // Submit/Insert action }), })
Assert Field Values Step
// Step 5: Assert values addTestStep(testSysId, 500, "sys_atf_step_config_assert_field_values", { description: "Verify incident was created correctly", inputs: JSON.stringify({ table: "incident", assertions: [ { field: "priority", operator: "equals", value: "1", }, { field: "state", operator: "equals", value: "1", // New }, { field: "number", operator: "is not empty", }, ], }), })
Server-Side Script Steps
Custom Validation Script (ES5)
// Step: Run Server Side Script // Script (ES5 only!):
;(function (outputs, steps, params, stepResult) { // Access outputs from previous steps var incidentSysId = steps["step_sys_id"].record_id
// Perform custom validation var gr = new GlideRecord("incident") if (gr.get(incidentSysId)) { // Check business rule fired if (gr.getValue("assignment_group") === "") { stepResult.setOutputMessage("Assignment group not set by business rule") stepResult.setFailed() return }
// Check SLA attached
var sla = new GlideRecord("task_sla")
sla.addQuery("task", incidentSysId)
sla.query()
if (!sla.hasNext()) {
stepResult.setOutputMessage("No SLA attached to incident")
stepResult.setFailed()
return
}
// All validations passed
outputs.incident_number = gr.getValue("number")
outputs.sla_count = sla.getRowCount()
stepResult.setOutputMessage("All validations passed")
} else { stepResult.setOutputMessage("Incident not found") stepResult.setFailed() } })(outputs, steps, params, stepResult)
Data Setup Script (ES5)
// Step: Setup test data ;(function (outputs, steps, params, stepResult) { // Create test user if needed var user = new GlideRecord("sys_user") user.addQuery("user_name", "atf_test_user") user.query()
if (!user.next()) { user.initialize() user.setValue("user_name", "atf_test_user") user.setValue("first_name", "ATF") user.setValue("last_name", "Test User") user.setValue("email", "atf@test.com") user.setValue("active", true) outputs.user_sys_id = user.insert() } else { outputs.user_sys_id = user.getUniqueValue() }
stepResult.setOutputMessage("Test user ready: " + outputs.user_sys_id) })(outputs, steps, params, stepResult)
Cleanup Script (ES5)
// Step: Cleanup test data (always runs) ;(function (outputs, steps, params, stepResult) { var testRecordId = steps["create_incident_step"].record_id
if (testRecordId) { var gr = new GlideRecord("incident") if (gr.get(testRecordId)) { gr.deleteRecord() stepResult.setOutputMessage("Cleaned up test incident: " + testRecordId) } } })(outputs, steps, params, stepResult)
Test Suites
Creating Test Suite
// Create test suite var suite = new GlideRecord("sys_atf_test_suite") suite.initialize() suite.setValue("name", "Incident Management Regression Suite") suite.setValue("description", "Full regression tests for incident management") suite.setValue("active", true) var suiteSysId = suite.insert()
// Add tests to suite function addTestToSuite(suiteId, testId, order) { var link = new GlideRecord("sys_atf_test_suite_test") link.initialize() link.setValue("test_suite", suiteId) link.setValue("test", testId) link.setValue("order", order) return link.insert() }
addTestToSuite(suiteSysId, createTestId, 100) addTestToSuite(suiteSysId, assignTestId, 200) addTestToSuite(suiteSysId, resolveTestId, 300)
Parameterized Tests
Using Test Parameters
// Test with parameters var test = new GlideRecord('sys_atf_test'); test.initialize(); test.setValue('name', 'Test: Create Incident with Priority'); test.setValue('parameters', JSON.stringify({ priority: '2', category: 'software' })); test.insert();
// In step, reference parameter { "values": [ { "field": "priority", "value": "${priority}" }, { "field": "category", "value": "${category}" } ] }

Best Practices
-
Isolate Test Data - Create and cleanup test data in each test
-
Use Impersonation - Test as actual user roles
-
Atomic Tests - Each test validates one scenario
-
Descriptive Names - Clear test and step descriptions
-
Order Steps - Use 100, 200, 300 for easy insertion
-
Handle Async - Add wait steps for async operations
-
Cleanup Always - Use finally steps for cleanup
-
Parameterize - Use parameters for reusable tests
