Скачать или смотреть Part 8 : Cucumber BDD : What is Data Table in Cucumber?

Data Tables in Cucumber are quite interesting and can be used in many ways. DataTables are also used to handle large amounts of data. They are quite powerful but not the most intuitive as you either need to deal with a list of maps or a map of lists. Most of the people get confused with Data tables & Scenario outline, but these two works completely differently.

Difference between Scenario Outline & Data Table
Scenario Outline:

This uses Example keyword to define the test data for the Scenario
This works for the whole test
Cucumber automatically run the complete test the number of times equal to the number of data in the Test Set
Test Data:

No keyword is used to define the test data
This works only for the single step, below which it is defined
A separate code needs to understand the test data and then it can be run single or multiple times but again just for the single step, not for the complete test
As I said above, the Data Tables can be used in many ways because it has provided many different methods to use. Let's just go through a few most popular methods. I will choose a simple scenario to illustrate the working of the Data Table but we will make effective use of this when we will do Cucumber Framework in the next series of this Cucumber Tutorial.

Data Tables in Cucumber
In this example, we will pass the test data using the data table and handle it using aslists() method.

Scenario: Successful Login with Valid Credentials
Given User is on Home Page
When User Navigate to LogIn Page
And User enters Credentials to LogIn
| [email protected] | Test@1234|
Then Message displayed Login Successfully
The complete scenario is same as what we have done earlier. But the only difference is in this, we are not passing parameters in the step line and even we are not using Examples test data. We declared the data under the step only. So we are using Tables as arguments to Steps.
