- 3. Why Automation ? - Benefits Benefits to Automation include increased software quality, improved time to market, repeatable test procedures, and reduced testing costs. REDUCED TESTING TIME IMPROVED TESTING PRODUCTIVITY IMPROVED PRODUCT QUALITY REDUCED QA COSTS CONSISTENT TEST PROCEDURES CAN SCHEDULE TEST RUNS 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 4. Manual vs. Automated Manual Execution More No. of resources required Slow,takes time to retest incase of testing in multiple environments There is a chance of overlook Automation Less No. of resources required Fast, Accurate and Reliable Improves testing productivity Easy to Learn & Maintain 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 5. Automation Methodologies Methodologies that have been found to be effective for automating functional or system testing for most business applications are broadly categorized as: 1. The "Functional Decomposition" Method: (Mostly followed for Desktop applications) To reduce all test cases to their most fundamental tasks, and write User-Defined Functions, Business Function Scripts, and "Sub-routine" or "Utility“ Scripts which perform these tasks independently of one another 2. The "Key-Word Driven" or "Test Plan Driven" Method: (Mostly followed for Web based applications) In this method, the entire process is data-driven, including functionality. This method uses the actual Test Case document developed by the tester using a spreadsheet containing special "Key-Words". 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 6. Why QTP ? Allows even novice testers to be productive in minutes. Create a test script by simply pressing a Record button and using an application to perform a typical business process. Each step in the business process is automated documented with a plain-English sentence and screen shot. Can easily modify, remove, or rearrange test steps. By capturing, verifying and replaying user interactions automatically, Identifies defects and helps ensure that business processes deliver the expected results and remain reliable throughout the lifecycle. Available for browser-based and Java-based applications and ERP/CRM solutions. 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 7. Why QTP ? Contd… Report displays all aspects of the test run: :: a high-level results overview, :: an expandable Tree View of the test script Specifying exactly :: Where application failures occurred The test data used Application screen shots for every step that highlight any discrepancies Detailed explanations of each checkpoint pass and failure Can share reports across an entire QA and development team 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 8. Why QTP ? Contd… Supports functional testing of all popular environments, including :: Windows, Web, .Net, Visual Basic, ActiveX, Java, SAP, Siebel, Oracle, PeopleSoft, terminal emulators 12/29/10 For more QTP Scripts, www.ramupalanki.com
- 9. Architecture Setup It takes at least 3 – 6 months to setup an architecture, which includes the following phases. 1. Installation: This includes hardware, software and network setup . 2 . Analysis: This includes better understanding/definition of the base system covering all the Functional Area to be automated. 3. Pilot Project: This covers the scripting of the base functional area based on the analysis/defined architecture.After Completion of pilot,a Parallel Run (Manual Vs. Automation) is required. 4. Architecture Acceptance: This includes the Test Run of the pilot project on the defined architecture to continue further automation of functional areas over the base project. 12/29/10 For more QTP Scripts, www.ramupalanki.com
