Robotic Process Automation Life Cycle

1. Analysis

The RPA life cycle begins with analyzing business processes that can be automated. Each process is evaluated for volume, frequency, stability, and error rate. Analysts identify rule-based activities that follow predictable patterns and involve structured data. This stage results in a detailed process definition document that outlines every step, decision point, and exception to help developers understand how the automation will operate.

2. Bot Development

After the analysis phase, developers start building the bot based on the approved process design. Using RPA tools such as UiPath, Automation Anywhere, or Blue Prism, they map each step into executable commands. Bots are configured to interact with applications, handle data, and follow logic that mirrors human decision-making patterns. Developers also include features for handling exceptions and security control so that the automation remains stable and auditable.

3. Testing

Testing ensures that the bot performs exactly as designed. Developers verify its ability to execute every workflow step under real conditions and confirm that it produces consistent results. Functional, exception, and performance tests are conducted to check data accuracy and reliability. If any deviation appears, the workflow is refined before moving to deployment. A properly tested bot ensures accuracy and confidence in production environments.

4. Support and Maintenance

Once deployed, bots are continuously monitored to confirm that they operate as expected. Any changes in source systems, user interfaces, or process rules require prompt updates in the automation logic. Maintenance involves fine-tuning workflows and adapting bots to evolving business requirements. Continuous support helps sustain process efficiency and extends the lifespan of automation initiatives across the organization.

Selenium Life Cycle

1. Test Plan

The process begins with defining a clear test plan. Teams outline what parts of the web application need to be automated, which browsers will be used, and what goals each test should achieve. The plan aligns testing objectives with project requirements so that coverage includes all critical user journeys. This foundation helps determine timelines, resources, and measurable quality targets.

2. Generating Basic Tests

Once the plan is ready, basic tests are created to verify core functionalities of the application. These initial scripts focus on actions such as logging in, submitting forms, and verifying responses. Selenium IDE is often used at this stage for quick recording and playback of user actions. The outcome provides an early validation of the test environment and confirms that automation scripts interact correctly with web elements.

3. Enhancing Tests

After the initial scripts work correctly, they are refined for better accuracy and maintainability. Developers introduce logic for handling conditions, input variations, and reusable methods. They also organize scripts into modular structures to simplify updates and extend coverage to complex user workflows. At this stage, integration with test data files and configuration management begins to support broader test execution.

4. Running and Debugging Tests

The enhanced scripts are executed through Selenium WebDriver or Selenium Grid across different browsers and platforms. Execution logs and console outputs are monitored to detect errors or failures. Debugging involves analyzing failed test steps, adjusting locators, and modifying scripts where elements or behaviors have changed. Parallel testing helps reduce time and validate application consistency across environments.

5. Analyzing Test Results and Reporting Defects

After execution, test outcomes are collected and analyzed. Reports highlight the number of passed, failed, and skipped cases along with execution logs. Defects identified during this stage are documented with clear evidence, such as screenshots or console traces. These reports are shared with the development team for resolution. Continuous tracking of defect trends helps improve both testing efficiency and product quality over time.
