Automation Framework
WORK IN PROGRESS
Overview
The purpose of data-driven testing with Selenium automation is to enhance the efficiency, effectiveness, and coverage of your testing efforts by systematically testing your application with multiple sets of input data.
Purpose
Below points are the purposes for using a data-driven testing framework
Increased Test coverage
Efficiency and Reusability
Regression Testing
Validation of Input Data
Scalability
Exploratory Testing Support
Parameterization
Maintaining Test Data Separately
Consistency and Reproducibility
Compliance and Regulation Testing
Technologies and tools
Selenium WebDriver - This provides a programming interface to interact with web elements and automate tasks in web applications
Java -
Maven - This is being used as a Dependency Management tool.
TestNG - TestNG is used as a framework and as a reporting tool as well.
Log4j - It's used to log messages within software and has the ability to communicate with other services on a system.
Apache POI - provides stream-based processing, that is suitable for large files and requires less memory. Apache POI is able to handle both XLS and XLSX formats of spreadsheets.
Webdriver Manager - WebDriverManager can automatically download and manage WebDriver dependencies for different browsers such as Chrome, Firefox, Safari, and Edge.
ReportNG -
Prerequisites
Test framework setup
Step 1: Set Up a Maven Project
Step 2: Add below mentioned Dependencies
Selenium Webdriver
Apache POI
TestNG
Webdriver Manager
log4j
ReportNG
Step 3: Create Data-Driven Test Class
Step 4: Create TestNG XML File
Step 5: Implement Data Provider
Step 6: Execute Tests
Test data preparation
The test data file format should be XLS or XLSX.
There should be a sheet with test data for each method and the sheet name should match the name of the method.
Each column name of the sheet should have a unique.
Any number of data can be passed
Test case design
Test scenarios
Each Page should have its own test class and each scenario should have its own method.
All Sanity and Regression scenarios are to be covered.
Both scenarios can be run separately.
Negative scenarios are also covered
Test steps
Provide both valid and invalid test data in the XLSX / XLS file
Provide only the required number of test data to avoid a longer run time.
Data-Driven testing implementation
Test data loading
XLX or XLSX files should be stored in
Mapping between the
ReadXLSDataclass and thetestdatashould be doneColumn Names of the sheets to be passed in the methods signature placeholder as parameters to fetch the data from the data provider.
Test execution
Set up test Environment
Create Test class
Implement data provider
Run test classes
Analyze test results
Reporting and logging
Test result reporting
TestNG is used as a report provider
Every class name is to be mentioned in the
testng.xmlfile to be a part of a reportShould be able to generate HTML emailable report by running the
testng.xml file.An
emailable-report.htmlandtesting-failed.xmlreports to be generated in the test-output file.
Logging
log4j has been used as a logging tool
This will provide the log for each test method that fails during the test suite execution
Finding the exact error in the test suite execution will be easy
Test environment configuration
Driver configuration
Driver configuration will be handled by the
Webdriver Manager.Webdriver Manager will manage the download, setup, and maintenance of the drivers required by Selenium WebDriver.
Test environment parameters
Users need to provide the browser name (Case insensitive) and URL of the environment in
configfiles > config.properties.
Maintenance and updates
Test data updates
Identify the need for updates, considering application changes, data quality, and new scenarios.
Update data in its source (e.g., Excel, database) to reflect current requirements and formats.
Ensure data validity by including boundary and edge cases.
Consider versioning data for tracking changes over time.
Codebase maintenance
