- 5. What is Data Driven Framework ? ● Data Driven Framework is a testing strategy in which the data set under test, is stored separately from the test script ● It is used to drive test cases and suites from an external data feed. The data feed can be data sheets like xls, xlsx, and csv files ● To read or write an Excel, Apache provides a very famous library POI ● This library is capable enough to read and write both XLS and XLSX file format of Excel ● Data Driven Testing is also known as parameterized testing or table driven testing ● The TestNG framework helps us with a parameterization feature in which we can parameterize different test values and even keep our test data separate from our test scripts
- 6. There are two ways by which we can achieve parameterization in TestNG and they are as follows: ● With the help of Parameters annotation and TestNG XML file @Parameters({“name”, “searchKey”}) ● With the help of DataProvider annotation @DataProvider(name= “searchProvider”)
- 7. Why Data Driven Testing ? ➔ Testers frequently have multiple data sets for a single test ➔ Data driven testing helps keeping data separate from test scripts ➔ The same test scripts can be executed for different combinations of inputs ➔ Test data maintenance involving lot of human resources with lot of time and manual efforts For Example:
- 8. Benefits of using the Data Driven Testing Framework ➔ Automation Testing is driven by the data set under test ➔ Same test script will work for different data sets ➔ Faster Execution ➔ Less Maintenance ➔ Permits better error handling
- 9. Selenium Webdriver + Apache POI ● Selenium Webdriver does not support read and write operations on excel files, but it can be supported with the integration of third party tool i.e Apache POI ● Apache POI is an open source library to work with Microsoft Documents
- 10. Integrating Selenium Webdriver and Apache POI 1. Using Maven: ● Go to IDE and create a project ● Add the required dependencies for Apache POI 2. Using Jars: ● Go to poi.apache.org ● Download the Jar file ● Add this jar file in your project directory
- 11. Integrating Selenium Webdriver and Apache POI Add these Apache POI Dependencies in pom.xml file: <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>4.1.2</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.1.2</version> </dependency>
- 12. “The coordination between the main code and data set will be taken care by TestNG Data Providers, which is a library that comes as a part of the Apache POI files.”
- 13. TestNG ● TestNG is the framework created for executing unit tests and it is also used by the software testers to efficiently run the automated test scripts created in Selenium Webdriver ● TestNG allows users to perform data-driven testing ● This testing allows users to execute the same test multiple times with multiple sets of data.
- 14. Data Driven Testing using @DataProvider ● TestNG supports two ways for passing parameters directly to our Test Methods. ● We can pass parameters through Data Providers or an xml File. ● To achieve the data-driven testing, DataProvider feature is used. ● DataProvider is a data feeder method that executes the test method with multiple sets of data. ● Similar to TestNG Parameters, DataProviders are a means to pass data to test scripts in TestNG. ● Using DataProvider in TestNG, we can easily inject multiple values into the same test case. ● It comes inbuilt in TestNG and is popularly used in data-driven frameworks.
- 15. Add TestNG in your Project ● Add the TestNG Dependency in pom.xml file: <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>7.4.0</version> <scope>test</scope> </dependency> ● Or, we can add Jar file in project directory.
