Codeless Data driven automation testing refers to creating automated test cases without writing code manually. Rather than writing code, testers rely on visual tools that allow them to design test cases through drag-and-drop actions or by recording user interactions.
There are few popular tools available in market which allow QA teams to create test scenarios visually and maintain them easily — especially useful for teams without deep programming skills.
DDT involves running a single test scenario multiple times with different input values taken from an external data source like:
1. Excel
2. CSV
3. Google Sheets
4. JSON / XML
5. Databases
In codeless platforms, data-driven testing is usually built-in or supported via plugins.
How It Works:
1. Create a test case using the tool’s visual interface.
2. Attach a data source (e.g., upload a CSV file or connect to a database).
3. Map test fields (like username, password, post title, etc.) to data columns.
4. Run the test – the tool will execute the same test with different rows of data
Let’s take one Use Case to test Login Functionality:
1. Classify the test cases:
a. Right UserName & Right Password
b. Wrong UserName & Right Password
c. Right UserName & Wrong Password
2. Create Test Steps for test cases:
3. Write Test Script:
// This is Pseudo Code
// Test Step 1: Launch Application
driver.get(“URL of the Application”);
// Test Step 2: Enter Username
txtbox_username.sendKeys(“valid”);
// Test Step 3: Enter Password
txtbox_password.sendKeys(“invalid”);
// Test Step 4: Check Results
If (Next Screen) print success else Fail
4. Create Excel/CSV for Input Data
5. Change the Script as per inputs
// This is Pseudo Code
// Loop 3 Times
for (i = 0; i & lt; = 3; i++) {
// Read data from Excel and store into variables
int input_1 = ReadExcel(i, 0);
int input_2 = ReadExcel(i, 1);
// Test Step 1: Launch Application
driver.get(“URL of the Application”);
// Test Step 2: Enter Username
txtbox_username.sendKeys(input_1);
// Test Step 3: Enter Password
txtbox_password.sendKeys(input_2);
// Test Step 4: Check Results
If(Next Screen) print success
else Fail
}
Benefits of Codeless DDT
Codeless Data-Driven Testing (DDT) offers a powerful combination of speed, scalability, and collaboration. In addition to these core advantages, it brings several other key benefits:
1. No coding required, making it easy for non-technical users to get started quickly.
2. Simple to maintain, even when UI elements or test data change frequently.
3. Highly scalable, ideal for automating repetitive test scenarios efficiently.
4. Well-suited for testing forms, authentication workflows, CMS platforms and more.
