Custom Steps

Create custom step types to handle specific testing scenarios not covered by built-in steps.

Creating Custom Steps

Step Definition

Define custom step behavior using JavaScript.

Basic Structure:

• Name: Clear, descriptive name
• Description: How to use the step
• Parameters: Configurable inputs
• Script: Custom JavaScript code

Custom Action Example

Validate API Response:

• Purpose: Check API endpoint responses
• Parameters: API URL, expected data
• Script: Custom validation logic

Custom Step Types

API Testing Steps

Test API endpoints and responses.

Example:

• Create User: Test user creation API
• Get Data: Retrieve data from API
• Update Record: Modify existing records
• Delete Item: Remove items via API

Database Steps

Interact with databases directly.

Example:

• Verify User Created: Check database for new user
• Count Records: Count items in database
• Check Data: Validate database content
• Clean Up: Remove test data

File Operations

Handle file system operations.

Example:

• Read Config File: Load configuration data
• Write Log File: Create log entries
• Check File Exists: Verify file presence
• Delete Files: Clean up temporary files

Advanced Custom Steps

Conditional Logic

Implement complex conditional behavior.

Smart Login:

• Check if already logged in
• Only login if needed
• Handle different user types
• Manage session state

Data Processing

Transform and validate data.

Process CSV Data:

• Read CSV file content
• Parse data into structured format
• Validate data integrity
• Return processed results

Custom Step Libraries

Organization-specific Steps

Create steps specific to your application domain.

E-commerce Steps:

• Add product to cart
• Process checkout
• Handle payments
• Manage orders

User Management Steps:

• Create user accounts
• Update user profiles
• Change passwords
• Delete accounts

Best Practices

Step Design

• Single Responsibility: One clear purpose per step
• Reusability: Design for multiple use cases
• Error Handling: Include proper error handling
• Documentation: Clear parameter descriptions

Performance

• Efficient Code: Optimize for execution speed
• Resource Management: Clean up resources
• Timeout Handling: Set appropriate timeouts
• Memory Usage: Avoid memory leaks

Security

• Input Validation: Validate all inputs
• Secure Storage: Handle sensitive data properly
• Access Control: Respect permission boundaries
• Audit Trail: Log important actions

Testing

• Unit Testing: Test custom steps in isolation
• Integration Testing: Test with real scenarios
• Error Scenarios: Test failure cases
• Performance Testing: Validate execution time
