Database Testing Using Selenium WebDriver – DB2

Database Testing Using Selenium WebDriver

In this post, let’s see how to do Database Testing using Selenium WebDriver. As we all know Selenium WebDriver is a tool to automate User Interface. We could only interact with Browser using Selenium WebDriver.

Sometimes, we may face a situation to get the data from the Database or to modify (update/delete) the data from the Database.  If we plan to automate anything outside the vicinity of a browser, then we need to use other tools to achieve our task. To achieve the Database connection and work on it, we need to use JDBC API Driver.

Must Read: What is Gecko Driver and how to use it in Selenium WebDriver. 

The Java Database Connectivity (JDBC) API provides universal data access from the Java programming language. Using the JDBC API, you can access virtually any data source, from relational databases to spreadsheets and flat files. It lets the user connect and interact with the Database and fetch the data based on the queries we use in the automation script. JDBC is a SQL level API that allows us to execute SQL statements. It creates a connectivity between Java Programming Language and the database.

Using JDBC Driver we could do the following

  1. Establish a Database connection
  2. Send SQL Queries to the Database
  3. Process the results

Loading the required JDBC (Java DataBase Connectivity) Driver class:

Note: The parameter varies between Data bases such as MySQL, MS SQL Server etc.,

Establishing a connection to the DataBase (DB2):

Connection URL Syntax (DB2):

Executing SQL Queries:

Results from the executed query are stored in the ResultSet Object.

Fetching data from result set:

Disconnecting the Database connection:

List of Methods to process the results:

Note: Assuming that you have already Installed Database.

Steps to follow – Database Testing using Selenium WebDriver:

  1. Click here to download the jar files.
  2. Add the downloaded jar file to your project

Note: Right click on your Java File – Click on Build Path – Configure build path – Select the libraries – Click on add external JARs – Select DB2 JDBC jar – Click on open to add it to the project

3. Copy the below mentioned script and modify as per your requirement and execute it

Note: You could find the detailed explanation of the script in the code snippet below
