Difference Between Scenario and Scenario Outline in Karate

Karate is an open-source test automation framework designed to perform API and web application testing. It is a Java-based framework that has gained popularity because of its simplicity and flexibility. Karate provides a straightforward way to write automated tests using a Cucumber-like syntax. Karate’s feature file-based approach allows testers and developers to write and execute tests in a readable and understandable format. In this blog post, we will discuss the difference between scenario and scenario outline in Karate.

Understanding Scenario in Karate

A scenario in Karate is a collection of steps that define a test case. A scenario consists of a set of steps, and each step is a combination of an HTTP request and an assertion. The purpose of a scenario is to test a particular feature of an API or web application.

A simple example of a scenario in Karate is as follows:

„`
Scenario: Verify Login API
Given url ‚https://example.com/api/login‘
And request {username: ‚testuser‘, password: ‚testpass‘}
When method post
Then status 200
„`

In the above example, we have defined a scenario to verify the login API of an application. The `Given` step defines the URL of the API, the `And` step sets the request body, the `When` step defines the HTTP method, and the `Then` step asserts the response status.

Understanding Scenario Outline in Karate

A scenario outline is a way to run the same scenario multiple times with different input values. It provides a method to reuse the same scenario with different data sets. In other words, instead of creating multiple scenarios, we can create one scenario with placeholders for input values.

A simple example of a scenario outline in Karate is as follows:

„`
Scenario Outline: Verify Get User API
Given url ‚https://example.com/api/user‘
And path id =
When method get
Then status

Examples:
|userId |expectedStatus |
|1 | 200 |
|2 | 404 |
„`

In the above example, we have defined a scenario outline to verify the get user API of an application with different user IDs. We have used placeholders for input values, in this case, `userId` and `expectedStatus`. The `Examples` section specifies the different data sets for each placeholder.

Differences Between Scenario and Scenario Outline

The key difference between scenario and scenario outline in Karate is that a scenario defines a single test case with fixed input values, while a scenario outline defines a template for one or more test cases with different input values.

Another difference is the use of placeholders. Scenarios do not use placeholders for input values, while scenario outlines use placeholders to pass different input values to the test case.

A scenario outline provides a more efficient way to write tests that require different input values. It reduces the need to create multiple scenarios, saving time and effort.

When to Use Scenario and When to Use Scenario Outline in Karate

Scenarios are ideal for testing APIs or web applications with fixed input values. Use scenarios when the test case requires a specific set of input values, and there is no need to run the same test case multiple times with different input values.

Scenario outlines are ideal for testing APIs or web applications with multiple input values. Use scenario outlines when the test case needs to be run multiple times with different input values. This is especially useful when testing data-driven applications.

Difference between scenario and scenario outline in karate

Karate is a popular automation testing framework that is used for testing web applications. It is easy to use, learn and understand. Karate supports two types of testing scenarios that are Scenario and Scenario Outline. These two terms may sometimes create confusion for beginners who are new to the Karate testing framework. In this blog post, we will describe the difference between Scenario and Scenario Outline in Karate along with their usage and examples.

What is a Scenario in Karate?

In Karate, a Scenario refers to a single test case that uses features, tags, and steps to represent a specific user action. It is a set of steps that follow the Given-When-Then format to test different functionalities of a web application. Each Scenario consists of a title and a list of steps written in Gherkin syntax, which is easy to read and understand.

Here is an example of a Scenario in Karate:

„`
Scenario: Login functionality
Given url ‚website URL‘
And text(‚Enter email‘).input(‚emailid@gmail.com‘)
And password(‚Enter password‘).input(‚password@123‘)
When button(‚Login‘).click()
Then urlContains(‚dashboard‘)
„`

In this example, we have written a scenario that tests the login functionality of a web application. It involves opening a URL, entering login credentials, clicking the Login button and verifying whether the dashboard URL is displayed.

What is a Scenario Outline in Karate?

Scenario Outline is a powerful feature in Karate that allows testers to run the same test case multiple times with different input data sets. It is similar to the data-driven testing framework used in other automation testing tools. It enables to write multiple scenarios in a single scenario outline.

Here is an example of a Scenario Outline:

„`
Scenario Outline: Login with multiple credentials
Given url ‚website URL‘
And text(‚Enter email‘).input(email)
And password(‚Enter password‘).input(password)
When button(‚Login‘).click()
Then urlContains(‚dashboard‘)
Examples:
| email | password |
| email1@gmail.com | password123 |
| email2@gmail.com | password345 |
„`

In this example, we have written a scenario outline that tests the login functionality of a web application with multiple sets of credentials such as email1@gmail.com,password123 and email2@gmail.com,password345. The Scenario Outline has two parts, the Scenario Outline with the scenario steps and Examples section that holds the input and expected output data sets.

Difference between Scenario and Scenario Outline in Karate

The primary difference between Scenario and Scenario Outline is that Scenario represents a single test case, while Scenario Outline represents multiple test cases with different input data sets. With Scenario Outline, you can execute the same test case multiple times with different input data sets, which is not possible with the Scenario.

Scenario Outline has some additional syntax that helps in iterating your tests, for instance, Examples section containing the input and expected output sets.

Difference between Scenario and Scenario Outline in Karate

When it comes to test automation, Karate is one of the most popular tools among software testers. It is an open-source testing tool that enables you to write automated tests using Gherkin syntax. Karate supports the use of scenarios and scenario outlines, which can sometimes create confusion among testers. In this blog post, we will discuss the difference between scenario and scenario outline in Karate.

What is a Scenario in Karate?

Scenario in Karate is a test case that is written in Gherkin syntax. It represents a specific test that needs to be executed. A scenario contains a set of steps that need to be executed in a particular order. Each step represents an action that needs to be performed or an expectation that needs to be verified. In Karate, you can define a scenario using the keyword ‚Scenario:‘, followed by the scenario name. For example:

Scenario: Login functionality test
Given url 'https://example.com/login'
When method POST
And request {"username":"testuser","password":"testpassword"}
Then status 200

In the above example, we have defined a scenario named „Login functionality test“. The scenario contains four steps that need to be executed in a particular order. The steps represent the actions that need to be performed or the expectations that need to be verified.

What is a Scenario Outline in Karate?

Scenario Outline in Karate is a way of specifying a set of scenarios that share the same structure but have different data inputs. It is useful when you want to test the same functionality with different data inputs. Scenario Outline allows you to define a template for a set of scenarios and specify examples for different data inputs. In Karate, you can define a Scenario Outline using the keyword ‚Scenario Outline:‘, followed by the template for the scenario and the data inputs. For example:

Scenario Outline: Login functionality test with multiple users
Given url 'https://example.com/login'
When method POST
And request {"username":"","password":""}
Then status 200

Examples:
| username  | password    |
| user1     | password1  |
| user2     | password2  |
| user3     | password3 |

In the above example, we have defined a Scenario Outline named „Login functionality test with multiple users“. The scenario outline contains four steps that need to be executed in a particular order. The steps represent the actions that need to be performed or the expectations that need to be verified. The scenario outline also contains an example table that specifies different data inputs for the same scenario.

What is the Difference between Scenario and Scenario Outline in Karate?

The main difference between Scenario and Scenario Outline in Karate is that Scenario is used when you want to test a specific functionality, while Scenario Outline is used when you want to test the same functionality with different data inputs. Scenario represents a single test case, while Scenario Outline represents a set of test cases that share the same structure but have different data inputs.

Another difference between Scenario and Scenario Outline is the way they are defined. Scenario is defined using the keyword ‚Scenario:‘, while Scenario Outline is defined using the keyword ‚Scenario Outline:‘. The steps in a Scenario are fixed and do not change, while the steps in a Scenario Outline are the same for all scenarios but the data inputs change for each scenario.

Lastly, Scenario Outline allows you to specify multiple examples for the same scenario, making it easier to test different data inputs. Scenario, on the other hand, is used when you want to test a specific functionality and do not need to test different data inputs.

Conclusion

In summary, Scenario and Scenario Outline are two important concepts in Karate that allow you to write automated tests using Gherkin syntax. Scenario is used when you want to test a specific functionality, while Scenario Outline is used when you want to test the same functionality with different data inputs. Understanding the differences between Scenario and Scenario Outline is crucial for writing effective automated tests using Karate.

It is important to note that Karate has many more features and capabilities that can help you write automated tests efficiently. We recommend you to explore the Karate documentation to learn more about how you can use Karate to write high-quality automated tests.
