1. The document discusses the development of a Python script generator web application using PHP and MySQL. It covers the concepts, requirements, architecture, features and benefits of the application. 2. The application aims to help validation engineers generate Python scripts for test automation without needing expertise in Python. It allows auto-population and updating of scripts based on test cases, libraries and functions selected. 3. In conclusion, the Python script generator reduced validation cycle times by eliminating syntax errors and the need for Python training, while providing a centralized repository for standardized test scripts.

- 3. 1. Today, PHP and MySQL are the most widely used combination of open source technologies for Web Application Development 2. In the presentation, we first discuss the various concepts that form a base-line for the development of web- technologies, followed by extensive focus on the specific application namely the Python Script Generator (PSG) 3. In the discussion of the Python Script Generator, the technologies that come into play behind the scenes are covered so that viewers of this presentation are acquainted with the knowledge to utilize the right technology for the application they intend to create WebApplicationDevelopmentusingPHPandMySQL 3 5/25/2013
- 5. The AMP stack consists of: A -> Apache the web-server. M -> MySQL the database. P -> PHP the server-side scripting engine. There are several open-source AMP stacks readily available for use such as: LAMP – Linux Apache MySQL PHP, Perl & Python WAMP – Windows Apache MySQL PHP MAMP – Mac Apache MySQL PHP XAMPP – Cross-platform Apache MySQL PHP Platform WebApplicationDevelopmentusingPHPandMySQL 5 5/25/2013
- 6. Free and open-source Maintained by the Apache Software Foundation Multi-platform & cross-platform support Good support in the form of mailing list and large community of users Strong Default Configuration PHP has several inbuilt functions to perform query with MySQL Ease of duplication of infrastructure on development machine WebApplicationDevelopmentusingPHPandMySQL 6 5/25/2013

- 8. 1. Storage, Retrieval, Management – Easy because database allows users to store data in a logic format 2. Security – Database adds to security of the web-application as database access includes secured authentication. 3. Independence – Data can be updated independently from the content of the web-site as well as from independent locations 4. Scalability – If data grows exponentially, it can be handled independently with respect to the web-site infrastructure. Database can be scaled across servers by implementation of several HDR options 5. Simple Integration – An existing database can be easily integrated 6. Load Sharing – Database queries are processed autonomously with respect to server-side scripts calling them, this decreases load on the server-side scripts. Moreover, data retrieval from database has been optimized over decades of data related studies 7. Concurrency – Databases provide robust concurrent multi-user access WebApplicationDevelopmentusingPHPandMySQL 8 5/25/2013
- 9. Client-side script Server-side script Processing Browser. Server. Process Script is sent to the browser. Script is fetched from file system into the server-side scripting engine Load User's computer. Server machine. Security Lower security because source-code of the script can be exposed on the user's computer. Higher security because source-code is interpreted and the resulting HTML is returned to the user's computer (Logic is secure). Speed Very quick, because processing is happening on user's computer There is delay in fetching the processed resource from the server. Dependency User's browser needs to support the client-side scripting language. It must also be enabled for the web- application to function smoothly. The result of server-side script processing is generally HTML which is supported on all browsers. Performance Improvement Performance can be improved by increasing hard-disk/RAM of the user's computer. There is performance impact seen when the user opens multiple web-application/web-pages on the browser simultaneously. Performance depends not only on server's hard-disk, RAM and the Network but also on simultaneous concurrent connections to the server-side application. Application Input-validation, user-interaction. Database or server-resource access Example CSS, JavaScript, AJAX, VBScript PHP, ASP.Net, Ruby on Rails, JSP, Perl WebApplicationDevelopmentusingPHPandMySQL 9 5/25/2013

- 16. Test automation is a challenging yet important field in Validation world An average validation engineer is not expected to be expert in any of the programming languages that can be used to create the scripts to automate test execution The idea was to create a tool that can aid validation engineers to generate scripts quickly and efficiently without the need of being an expert in the scripting language Common Python script errors were improper indentations and spelling mistakes which were reducing the performance of validation engineers WebApplicationDevelopmentusingPHPandMySQL 16 5/25/2013

- 36. Common standard of test-case script creation – a benchmark tool web-application - available everywhere, no need to install It has eliminated the chances syntax errors such as spelling mistakes and problematic indentations. It does not require a Python expert to create a test-case script. This eliminates the need to train people in Python to create the wrapper files. Updating library - now independent of script creation Fast Centralized repository of scripts WebApplicationDevelopmentusingPHPandMySQL 36 5/25/2013
- 37. Using AMP stack can help developers reduce the application development time. The python code generator enabled rapid development of test-case execution scripts thereby reducing the duration of validation cycle. In this project, no of scripts in library were ~800 where as scripts were ~4000 This give domain experts more time to create efficient & more generic scripts WebApplicationDevelopmentusingPHPandMySQL 37 5/25/2013

In this presentation, we discussed the concepts which come into play during developing a web- application Distinction between Client-side and Server-side scripting Benefits of implementing a database with web-sites The advantages of AMP stack was also discussed, where we saw why PHP worked so well with MySQL Test cycle used in the Automation Team was discussed, this was followed by requirements of Python Script Generator Architecture and Detailed implementation of each feature was discussed with a brief description of problems solved by the tool WebApplicationDevelopmentusingPHPandMySQL 38 5/25/2013
