Introduction to Automation Drawbacks of Manual testing - Manual testing is time-consuming and tedious. Introduction to Automation Drawbacks of Manual testing - Manual testing is time-consuming and tedious. - Requiring a heavy investment in human resources. - Time constraints often make it impossible to manually test every feature thoroughly before the application is released. - Low reliability. Manual Testing

Automation Testing Process Automated testing involves three main steps Creating Script(s) Executing Script(s) Analyzing Automation Testing Process Automated testing involves three main steps Creating Script(s) Executing Script(s) Analyzing Result(s) The QTP testing process consists of 7 main phases: v v v v Preparing to record Recording a session on your application Enhancing your test Debugging your test Running your test Analyzing the test results Reporting defects

Introduction to QTP Framework What and Why What is an Automation Framework: v. A Introduction to QTP Framework What and Why What is an Automation Framework: v. A test automation framework is a set of assumptions, concepts, and practices that provide support for automated software testing. v. A comprehensive architecture to drive the complete test automation process. What is the need of having a Test Automation Framework: v. Pitfalls of available standard Test Automation tools. v. Testers are testers not programmers. v. Complexity and Maintenance. v. Test tool Costs. v. Test Automation is seldom a full time effort.

Maintainability v. Removes most testers from automation complexities v. Can make automation efforts more holistic: Application independent v. Minimize Automation Risks v. Ensure Automation ROI

Type of Automation Frameworks v. Data Driven Framework v. Modularity Framework v. Keyword Driven Type of Automation Frameworks v. Data Driven Framework v. Modularity Framework v. Keyword Driven Framework v. Hybrid Framework

Type of Automation Frameworks Contd. Data Driven Framework v. Data-driven framework is one where Type of Automation Frameworks Contd. Data Driven Framework v. Data-driven framework is one where test input and output values are read from data files (ODBC sources, Text files, Excel files, DAO objects, ADO objects, and such) and are loaded into variables that are coded in scripts v. Data Driven testing is implemented for applications whose behavior is data dependent- Test Scenarios are to be run one or more set of data values which vary for each execution cycle v. Data Driven Framework can be combined with Modular or Keyword Driven Framework to create a Hybrid Framework

Type of Automation Frameworks Contd. Modular Framework v. Requires creation of small, independent scripts Type of Automation Frameworks Contd. Modular Framework v. Requires creation of small, independent scripts that represents modules/sections/functions of the application under test. v. The modules are then used in a hierarchical or logical fashion to construct larger test realizing an actual test case. v. Features in QTP to support Modularity Framework: ØReusable Actions ØFunctional Libraries

Type of Automation Frameworks Contd. Keyword Driven Framework v. Keyword-driven testing framework refer to Type of Automation Frameworks Contd. Keyword Driven Framework v. Keyword-driven testing framework refer to an application-independent automation framework. v. This framework requires the development of data tables and keywords, independent of the test automation tool used to execute them. v. The driver code "drives" the application-under-test, keyword driven test and the data. v. Keyword-driven tests look very similar to manual test cases. v. In a keyword-driven test, the functionality of the application-under-test is documented in a table like structure for e. g. Excel Sheet (similar to keyword view in QTP).

Hybrid Framework v. The most successful automation frameworks generally accommodate both keyword driven testing Hybrid Framework v. The most successful automation frameworks generally accommodate both keyword driven testing as well as data driven scripts. v. Hybrid is a combination of Functional Decomposition and Data Driven Framework. v Modularity can be achieved by nesting the test scripts and using library files to implement reusable components (Reusable Actions and Functions). Hybrid = Keyword Driven + Data Driven Hybrid = Modularity + Data Driven

Startup Script v. Instead we have Initialization Script where you have to write your Startup Script v. Instead we have Initialization Script where you have to write your own VB Script to make QTP to run this script before executing each test. v. We can put start applications URL/Address/Exe file path in the default record or run settings for Windows/WEB applications. v. QTP opens immediately that particular application or URL will open.

Driver Script Driver script is the single main script of the Driver Engine. It Driver Script Driver script is the single main script of the Driver Engine. It iteratively traverses through the data of business scenario flow and calls the respective reusable scripts sequentially. It also enables us to execute a reusable script any number of times in a particular data row of the variable test data sheet. It also updates the database for execution results of a particular script run

Test Schedulers There can be situations when you need to schedule your QTP scripts Test Schedulers There can be situations when you need to schedule your QTP scripts so that they can run when you are not present in front of your PC.

Object Repository v. Object Repository acts as a translator between QTP script and the Object Repository v. Object Repository acts as a translator between QTP script and the Operating System. v. QTP stores information it learns about a window or an object in object repository. v. When QTP runs a test, it uses the object repository to locate objects. v. QTP reads an object description in the repository and then looks for an object with the same properties in the application under test.

Test Data As per the scenarios which are in regression test suite, enter all Test Data As per the scenarios which are in regression test suite, enter all the required test data into the excel file and save it in the test data folder which is specified in the framework.

Reporting Mechanism When executing the scripts through QTP, we can get the HTML reports Reporting Mechanism When executing the scripts through QTP, we can get the HTML reports which is user friendly, where as running them through QC then auto generic reports.

Selection of the test cases to be automated will be based on the business risk attached to each test Tests that need to run once and those that need frequent human intervention are usually not worth the investment to automate and need not be considered for automation Avoiding business scenarios where complex hardware is involved Sample feasibility analysis report.

Accessing Test Data is defined in separate excel files for each application in Move Accessing Test Data is defined in separate excel files for each application in Move Test Scripts written in QTP will access the Test Data using QTP’s Data Table feature. Test data defined in separate excel files will be imported into QTP’s Data Table. Importing Test Data from external excel files will be done using an import statement. Following syntax used to import a sheet from test data. xls file to a sheet in data table Syntax : Datatable. Import. Sheet “Location of Test. Data. xls file”, “sheet ID in Testdata. xls file” , “Sheet id/sheet name in data table" Example: Datatable. Import. Sheet “C: Testdata. xls”, 3, “Login"

Reusable Components There are two types of Reusable Components v Reusable Action v User Reusable Components There are two types of Reusable Components v Reusable Action v User Defined Functions v Generic Functions v Business Functions Reusable Actions and User Defined Functions are maintained in separate folders for entire application. The advantage of using Reusable Actions is that it can be easily debugged and can use the intelligence feature of QTP IDE. All common scenarios will be captured using Reusable actions. Functions will be used for performing generic tasks e. g. like splitting a string, etc. These tasks are application independent.

Environment File v. Environment files are also called as initialization files or configuration files. Environment File v. Environment files are also called as initialization files or configuration files. v. Environment files are created in external files with. xml format v. Create Environment variables to access information like Server Name, Application URL, username, password, library files and Test Data. v. This file can be used across all the called Actions and in all the Test Scripts. v. Throughout the test the value of an Environment Variable remains the same.
