Documentation for Automated Test Execution System

  1. Scope

The scope of this project is to automate the process of executing test cases on a Hardware-in-the-Loop (HIL) PC without the need for constant human monitoring. The system aims to:

Automatically receive specific test instructions via email.

Download and process Excel-based test case files.

Execute the test cases using XIL API.

Generate and send a report back to the sender after execution.

This will significantly optimize the utilization of the test bench, ensure continuous testing, and minimize idle time.

  1. Working Method

The system works through the following stages:

Stage 1: Receiving Email with Test Cases

  1. A designated person sends an email to the HIL PC with a specific subject line and an Excel file containing test cases as an attachment.

  2. The HIL PC automatically monitors incoming emails in Outlook, filtering by:

Specific subject line (e.g., "Start Execution: Feature XYZ").

Sender’s email address.

Stage 2: Processing the Attachment

  1. Upon receiving a valid email:

The system downloads the Excel file.

The file is saved to a predefined directory on the HIL PC.

Stage 3: Executing the Test Cases

  1. The XIL API is used to interface with the test bench and execute the test cases listed in the Excel file.

  2. During this process, the system logs the progress and status of the test cases.

  3. Once all test cases are executed, a detailed report is generated.

Stage 4: Sending Execution Report

  1. After the execution is complete, a new email is automatically generated.

The email includes a subject line such as "Execution Report: Feature XYZ".

The test report is attached.

  1. The email is sent back to the original sender.
  1. Benefits

Automated Workflow: Reduces the need for manual intervention, allowing the system to autonomously manage test executions.

Increased Efficiency: Ensures the test bench is never idle, maximizing the time spent executing tests.

Automated HIL Test Execution System

  1. Scope

The Automated HIL Test Execution System is designed to streamline the testing process for Hardware-in-the-Loop (HIL) systems by eliminating manual intervention. The key objective is to automate the execution of test cases on the HIL PC triggered by specific emails, thus ensuring that test benches remain fully utilized, even in the absence of staff. The system operates by monitoring incoming emails, extracting attached Excel files containing test cases, executing them on the test bench using XIL API, and finally sending a report back to the original sender.

  1. Working Method

The system follows a structured sequence of operations, triggered by specific emails:

Stage 1: Email Monitoring

Monitoring Incoming Emails:

The system continuously monitors the Outlook inbox of the HIL PC for emails matching pre-defined sender addresses and subject lines.

This ensures that only authorized personnel can trigger the test execution process.

Stage 2: Filtering and Downloading Attachments

Email Filtering:

Upon receiving an email, the system checks if the subject and sender match any of the predefined criteria.

If a match is found, it verifies if the email contains an Excel attachment (.xls or .xlsx format).

Attachment Processing:

The Excel file is downloaded and saved to a specific directory on the HIL PC for further processing.

The file is then parsed to extract the test case details, including parameters and configurations required for execution.

Stage 3: Test Execution Using XIL API

XIL API Integration:

The XIL (Test Automation Interface) API is used to interact with the HIL system, automating the execution of test cases contained within the Excel file.

The system runs each test case sequentially or in parallel based on the complexity and type of test.

Logging and Tracking:

Throughout the execution, logs are generated to track the status of each test case (e.g., pass/fail, errors, execution time).

This provides a detailed record of the test session, which is used later to generate a comprehensive report.

Stage 4: Report Generation and Emailing

Report Generation:

After completing the test execution, the system automatically generates a report, summarizing the results of each test case.

This report includes key metrics such as test case IDs, execution time, pass/fail status, and any errors encountered during the execution.

Sending Results via Email:

Once the report is generated, the system composes a new email, attaches the report, and sends it to the original sender with a predefined subject line (e.g., "Execution Report: Feature XYZ").

This ensures that the user receives feedback on the execution in a timely manner.

  1. Benefits

A. Continuous Utilization of Test Bench

24/7 Operations: The automated system allows the test bench to remain operational even during non-working hours or when personnel are unavailable, maximizing test throughput.

B. Faster Turnaround Time

Reduced Downtime: As soon as a test is completed, the system is ready to handle new test case submissions, eliminating the need for manual initiation and reducing idle time.

Real-Time Execution: Emails trigger immediate processing, allowing test cases to be executed almost as soon as they are received.

C. Improved Accuracy

Minimized Human Error: By automating the execution and reporting process, the system minimizes the risk of human errors, such as incorrect test configurations or forgotten tests.

D. Remote Operation

Global Accessibility: The system can be triggered from anywhere by sending an email, making it ideal for remote teams and facilitating collaboration between geographically dispersed teams.

E. Enhanced Reporting

Detailed Reports: Comprehensive execution reports are generated automatically, providing detailed insights into the performance of each test case and highlighting any issues.

  1. Future Plans

A. Advanced Scheduling

Time-based Triggers: Implement the capability to schedule tests at specific times, allowing for automated batch processing of test cases during off-peak hours.

B. Integration with CI/CD Pipelines

Continuous Integration: Integrating the system with CI/CD pipelines (such as Jenkins, GitLab CI) would enable automatic test case execution as part of the software build and deployment process.

C. Intelligent Test Case Selection

AI-Driven Test Prioritization: Leveraging machine learning algorithms to prioritize test cases based on factors such as failure probability, execution time, and historical results.

D. Web-based Dashboard

Real-Time Monitoring Dashboard: Develop a web-based dashboard that allows the testing team to monitor ongoing executions, view logs, and manage the system remotely.

E. Integration with Cloud-Based Testing Tools

Cloud Integration: Future versions could incorporate cloud-based tools to facilitate more scalable and flexible test executions, including the ability to run tests on virtualized environments.
