What is the difference between scenario and scenario outline in cucumber? Other Differences: - In a single execution, Scenario is executed only once whereas Scenario outline (For similar data trace) can be executed multiple times depending upon the data provided as Example.
What is Scenario Outline in cucumber?
The Scenario Outline steps provide a template which is never directly run. A Scenario Outline is run once for each row in the Examples section beneath it (except for the first header row). More in the Writing Features guide. Also Know, what is a scenario in cucumber?
What is the difference between scenario and Scenario Outline?
Other Differences: - In a single execution, Scenario is executed only once whereas Scenario outline (For similar data trace) can be executed multiple times depending upon the data provided as Example. In this regard, what is the difference between scenario and scenario outline?
What is Scenario Outline in Gherkin?
In Gherkin language, scenario outline is the keyword which is used to run the same scenario multiple times. It is also defined as "Scenario outlines are used when the same test is performed multiple times with a different combination of values." The keyword scenario outline can also be used by the name Scenario Template.
When to use scenario outline data tables?
In nutshell, when scenario does not change but only the data value gets changed, it is advisable to use scenario outline data tables.
What is the difference between a scenario and a scenario outline?
Scenario Outline is simply a scenario with a set of examples. Whenever you need to use the Examples section, you need to use the Scenario Outline instead of a Scenario . The difference is that a Scenario will be executed once while Scenario Outline is executed for each example from the table.
What is scenario outline Cucumber?
Advertisements. Scenario outline basically replaces variable/keywords with the value from the table. Each row in the table is considered to be a scenario. Let's continue with the same example of Facebook login feature.
Can we use scenario and scenario outline in same feature file?
The short answer is yes, it is perfectly fine to have multiple Scenario Outlines within one feature file. However, the unspoken concern with this question is the potential size of the feature file. If one Feature has multiple Scenario Outlines with large feature tables, then the feature file could become unreadable.
Why do we use scenario outline?
The Scenario Outline keyword can be used to run the same Scenario multiple times, with different combinations of values. The keyword Scenario Template is a synonym of the keyword Scenario Outline . We can collapse these two similar scenarios into a Scenario Outline .
Why do we use scenario outline in Cucumber?
Cucumber Scenario Outline in Gherkin Based from Gherkin Reference, the Scenario Outline keyword can be used to repeat the same steps with different values or arguments being passed to the step definitions. This is helpful if you want to test multiple arguments in the same scenario.
What is the difference between hooks and background in Cucumber?
After hooks will be run after the last step of each scenario, even when there are failing, undefined, pending or skipped steps. Background is used to set up a precondition. A Background is run before each scenario, but after any Before hooks. In a feature file, we should add the Background before the first Scenario.
Can we use background with scenario outline?
If different groups need different backgrounds, and it's not possible to just use scenario outlines to group them, then perhaps split the specification into multiple feature files. Each file will be shorter, and it can use a more focused background section to prepare only the common aspects for its own scenarios.
What is dry run in Cucumber?
Cucumber dry run is used for compilation of the Step Definition and Feature files and to verify the compilation errors. The value of dry run can be either true or false. The default value of dry run is false and it is a part of the Test Runner Class file.
Can we have multiple scenarios in feature file?
Feature file can contain multiple scenarios or scenario outlines. We can write all possible Scenarios of a particular feature in a feature file. By using the keyword "Scenario" or "Scenario Outline", One Scenario can be separated from another.
What is glue in Cucumber?
Glue Option helps Cucumber to locate the step definition file. We specify the package to load glue code (step definitions or hooks) in the glue option. When no glue is provided, Cucumber will use the package of the annotated class. For example, if the annotated class is com.
What is a scenario in Gherkin?
Scenarios. Scenario is one of the core Gherkin structures. Every scenario starts with the Scenario: keyword (or localized one), followed by an optional scenario title. Each feature can have one or more scenarios, and every scenario consists of one or more steps.
What is the difference between data table and example in Cucumber?
Use Example Table where ENTIRE scenario needs to be tested with different/multiple test data. Use Data table where test data is Explicitly meant for specific steps and user would like to interpret based on use case internally.
2. Adding Cucumber Support
To add support for Cucumber in a simple Maven project, we will need to add the following dependencies:
3. A Simple Example
Let's demonstrate both a bloated way and a concise way of writing featured files. Let's first define the logic we want to write a test for:
4. Defining Cucumber Tests
Feature: Calculator As a user I want to use a calculator to add numbers So that I don't need to add myself Scenario: Add two numbers -2 & 3 Given I have a calculator When I add -2 and 3 Then the result should be 1 Scenario: Add two numbers 10 & 15 Given I have a calculator When I add 10 and 15 Then the result should be 25
5. Rewriting Features Using Scenario Outlines
We saw in Section 4.1. how defining a feature file can be a time-consuming task and more error prone. The same feature file can be reduced to mere few lines using the Scenario Outline:
6. Conclusion
With this quick article, we've shown how scenarios can be made generic in nature. And also reduce effort in writing and maintaining these scenarios.
What is a scenario in cucumber testing?
What is Scenario in Cucumber Testing? The scenario is one of the core structures of the Gherkin language. Scenario includes all the possible circumstances of the feature and test scripts for these circumstances. The keyword " Scenario " represents a scenario in Gherkin language. One feature can have multiple scenarios, ...
What is scenario outline?
In Gherkin language, scenario outline is the keyword which is used to run the same scenario multiple times. It is also defined as "Scenario outlines are used when the same test is performed multiple times with a different combination of values.".
Introduction
Adding Cucumber Support
- To add support for Cucumber in a simple Maven project, we will need to add the following dependencies: Useful links to dependencies from Maven Central: cucumber-junit, cucumber-java, hamcrest-library Since these are testing libraries, they don't need to be shipped with the actual deployable – which is why they're all testscoped.
A Simple Example
- Let's demonstrate both a bloated way and a concise way of writing featured files. Let's first define the logic we want to write a test for: Let's first define the logic we want to write a test for:
Defining Cucumber Tests
- 4.1. Defining a Feature File
As seen here, 2 different combinations of numbers have been put to test here the addition logic. Apart from numbers, all the scenarios are exactly the same. - 4.2. “Glue” Code
In order to test out these scenarios, i's essential to define each step with corresponding code, in order to translate a statement into a functional piece of code:
Rewriting Features Using Scenario Outlines
- We saw in Section 4.1. how defining a feature file can be a time-consuming task and more error prone. The same feature file can be reduced to mere few lines using the Scenario Outline: When comparing a regular Scenario Definition with Scenario Outline, values no longer need to be hard-coded in step definitions. Values are replaced with parameters as <parameter_name>in step-def…
Conclusion
- With this quick article, we've shown how scenarios can be made generic in nature. And also reduce effort in writing and maintaining these scenarios. The complete source code of this article can be found over on GitHub.
