Topicsy What is an Automation Framework?

y Types of Automation Framework

y Generic Framework Componentsy Framework Directory Structure

Automation Framework:y Is a set of testing assumptions, concepts, practices and tools that

provide support for automated software testing.

y It is not a tool to perform some specific task, but an

infrastructure that provides a complete solution where differenttools work together in an unified manner, hence providing acommon platform to the automation engineers using them.

y Provides an Outline of overall Test Structure

y Ensures Consistency of Testing

y Minimizes the amount of code for development which means Low

Maintenance cost.y Maximizes Reusability

y Reduces Exposure of Non-Technical Testers to Code

y Enables Test Automation using different sets of Data

Record and Playbacky It is the simplest of all Frameworks and also know as Linear Scirpting".

y Manually records each step ( Navigation and User Inputs), InsertsCheckpoints ( Validation Steps) in the first round .

y Then Play back the recorded script in the subsequent rounds.

Data Driveny Repeated use of Test Scripts with Different Inputs and Response Data

coming out of predefined Dataset

y In this framework, variables are used for both input values and output

verification values.y Each test case is combined with a related data set and executed using a

reusable set of test logic.

y Navigation through the program, reading of the data files, and loggingof test status and information are all coded in the test script.

y Helps in Reducing Coding for Large Test Casesy Ease of Testing of Time-Consuming & Complex Test Cases

Data Driven ..contd


9/20

Modular or Functional Decompositiony Modularity framework requires the creation of small, independent

scripts that represent modules, sections, and functions of theapplication-under-test. These small scripts are then used in a

hierarchical fashion to construct larger tests, realizing a particular testcase.

y Modular components are often created to correspond with applicationfunctionality but many different types of user-defined functions can becreated.

Functional Decomposition ..contd


11/20

Keyword Driveny Keyword driven framework is one where (pre-defined) keywords are

used to describe the actions. These actions match up to a process,related to the application.

y Keyword-driven testing splits the test procedure into logicalcomponents and these components are then used repeatedly in theassembly of new test scripts.

y Data & Keyword Tables remain independent of the Automation Tool

y Testers can develop scripts without a functioning application.

y Needs more scripting proficiency.

Keyword Driven ..contd


13/20

Hybrid Frameworky Combination of all the frameworks types

y allows data driven scripts to take advantage of the

powerful libraries and utilities that usually accompanya keyword driven architecture.

y Use Linear scripts in Areas which are too difficult toconvert into Keywords

FrameworkD

esign Componentsy Driver Script: It coordinates test activities by calling a sequence of

automated test scripts. It controls everything that takes place during thetest run, which allows the unattended execution of several scripts.

y Initialization Scripts:An initialization script sets parameters that areused throughout the test run and bring the test environment to a

controlled, stable state.y Configuration Scripts: It sets the parameters that are related to

Application under test and those parameters that are changed relativelyfrequently. Eg: User Ids, Passwords,Web URLs

y Test Scripts: Test scripts contain the logic that verifies specificapplication functionality.

y User-defined Functions: User-defined functions are custom, modularcomponents created for reuse and ease of maintenance, and may becreated at a level that they are reusable for multiple applications, or maybe created in such a way that they are reusable for just tests within asingle application.

Framework Design Components Contd..y Types ofUserDefined Functions:

y Utility Functions

y Navigation Functions

y

Error-handling Functionsy Miscellaneous Functions

y Error Handler or RecoveryScenarios: responsible for handlingunexpected occurrences during the test execution, such that the testrun continues and/or concludes in the most graceful manner possible.

y

ReportingUtility: responsible for collating the results from the runand presenting them as reports and logs that are designated parts ofthe framework.

y DataTable: Data sources (like spreadsheets) used to store test data foruse during test execution
