Data-Driven Testing in Robot Framework 


In this tutorial, we will discuss data-driven testing in the Robot Framework.

What is Data Driven Testing?

Data Driven Testing is a type of software testing in which test data is maintained in table or spreadsheet format. Data-driven testing enables testers to provide a single test script that may perform tests for all test data from a table and expect the test results to be returned to the same table. Table-driven testing is another name for parameterized testing.

Implementation Steps


  1. Install Python
  2. Install PIP
  3. Install Robot Framework
  4. Install Robot framework Selenium Library
  5. Install PyCharm IDE

Please refer to this tutorial to install Robot Framework – How to install and setup Robot Framework for Python.

Implementation Steps:

Step 1.1 – Open PyCharm and create a new project. Go to File and select New Project from the main menu.

Step 1.2 – Choose the project location. Click the “Browse” button next to the Location field and specify the directory for your project.

Deselect the Create a welcome script checkbox because you will create a new Python file for this tutorial.

Click on the “Create” Button.

Step 1.3 – A new dialog appears asking to open the project using any one of the given options. I have selected New Window as I like to have separate windows for each project.

Below is the image of the new project created in PyCharms.

Step 2 – Create a new directory in the new project

Right-Click on the project, select New->Directory and provide the name as DataDriven

Below is the image of the new directory.

Right-click on the new directory and select New File and provide the name as DataDrivenTesting_Demo.robot as shown below:

Step 3 – Download ChromeBinaries from the below location

The tests are going to use the Chrome browser, so we need to download the ChromeBinaries to open a blank browser in Chrome.

The chromedriver and geckodriver are placed in a folder name drivers in the RobotFramework_Demo project. I have renamed chromedriver to Chrome and geckodriver to Firefox.

Step 4 – Create a Data Driven Test

We are now going to write test cases. The test case details will be as follows :

A locator is an identifier for the web elements used to identify an element on the web page like id, name, class, xpath, css selector.

To know more about locators, refer to these Selenium Tutorials:

 Locators in Selenium – Locate by ID, ClassName,  Name, TagName,  LinkText, PartialLinkText

Dynamic XPath  in Selenium WebDriver

CSS Selector in Selenium WebDriver

Below is an example of a Data-Driven Test

*** Settings ***
Documentation   To validate the Login form
Library     SeleniumLibrary
Test Teardown   Close Browser
Test Template   Validate UnSuccesful Login
Documentation   To validate the Login form
Library     SeleniumLibrary
Test Template   Validate UnSuccesful Login

*** Variables ***
${browser_name}     Chrome
${login_btn}        css:.orangehrm-login-button
${login_error_message}      css:.oxd-alert-content--error

*** Test Cases ***              username        password
Invalid username                abc             admin123
Invalid password                Admin           abc
Special characters              @#$             %$^&
Invalid username and password   abc             abc123

*** Keywords ***
Validate UnSuccesful Login
    [Arguments]     ${username}     ${password}
    Open the Browser with URL
    Fill the login form         ${username}      ${password}
    Verify the error message is correct
    Close Browser Session

Open the Browser with URL
    Create Webdriver    ${browser_name}  executable_path=/Vibha_Personal/RobotFramework_Demo/drivers/${browser_name}
    Go To
    Maximize Browser Window
    Set Selenium Implicit Wait    2

Fill the login Form
    [arguments]         ${username}          ${password}
    Input Text          name:username        ${username}
    Input Password      name:password        ${password}
    Click Button        ${login_btn}

Verify the error message is correct
   ${result}=   Get Text    ${login_error_message}
   Should Be Equal As Strings     ${result}     Invalid credentials

Close Browser Session
    Close Browser

In the below image, it shows that there are 3 steps to creating a Data-Driven test.

All the below-mentioned keywords are derived from SeleniumLibrary. The functionality of keywords mentioned above:

. Create Webdriver − The keyword creates an instance of Selenium WebDriver.

2. Go To – This keyword navigates the current browser window to the provided url.

3. Maximize Browser Window – This keyword maximizes the current browser window.

4. Set Selenium Implicit Wait – This keyword sets the implicit wait value used by Selenium.

5. Input Text − This keyword is used to type the given text in the specified textbox identified by the locator name:username.

6. Input Password – This keyword is used to type the given text in the specified password identified by the locator name:password.

The difference compared to Input Text is that this keyword does not log the given password on the INFO level.

7. Click button – This keyword is used to click the button identified by the locator. In this case, it is “Login” button.

8. ${result} – This is a variable that holds the text value of the error message that is located by css:.oxd-alert-content–error.

9. Get Text – This keyword returns the text value of the element identified by located by css:.oxd-alert-content–error.

10. Should Be Equal As Strings – This keyword is used from builtIn keyword. This keyword returns false if objects are unequal after converting them to strings.

These keywords are present in SeleniumLibrary. To know more about these keywords, please refer to this document –

To run this script, go to the command line and go to directory tests.

Step 5 – Execute the tests

We need the below command to run the Robot Framework script.

 robot DataDrivenTesting_Demo.robot

The output of the above program is

Step 6 – View Report and Log

We have the test case passed. The Robot Framework generates log.html, output.xml, and report.html by default.

Let us now see the report and log details.


Right-click on report.html. Select Open In->Browser->Chrome(any browser of your wish).

The Report generated by the framework is shown below:


Robot Framework has multiple log levels that control what is shown in the automatically generated log file. The default Robot Framework log level is INFO.

Right-click on log.html. Select Open In->Browser->Chrome(any browser of your wish).

That’s it! Congratulations on making it through this tutorial and hope you found it useful! Happy Learning!!
