In Cucumber. js, “world” is an isolated scope for each scenario. That means all the step definitions, hooks, etc., for a scenario, is a part of a world and this data can be accessed within the world.
What are hooks in Cucumber?
Hooks are blocks of code that can run at various points in the Cucumber execution cycle. They are typically used for setup and teardown of the environment before and after each scenario. Where a hook is defined has no impact on what scenarios or steps it is run for.
What is object factory in Cucumber?
The Cucumber object factory. Whenever Cucumber needs a specific object, it uses an object factory. Cucumber has a default object factory that (in case of Guice) creates a default injector and delegates object creation to that injector.
What is scenario context in Cucumber?
Scenario Context class holds the test data information explicitly. It helps you store values in a key-value pair between the steps. Moreover, it helps in organizing step definitions better rather than using private variables in step definition classes.
What is the use of dependency injection in Cucumber?
In Cucumber, if we want to share state between multiple step definition files, we will need to use dependency injection (DI). There are several options: PicoContainer, Spring, OpenEJB, etc. If you’re not already using DI, then it is recommended to use PicoContainer.
What is runner file in Cucumber?
We can run tests using a test runner file for Cucumber. The test runner file should contain the path of the feature file and step definition file that we want to execute. Code Implementation of the Feature file. Feature − Login Module.
What is glue code in Cucumber?
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.
What is Pico container?
Picocontainer is responsible for instantiating objects and resolving their constructor dependencies. This greatly simplifies code, in that any Picocontainer-instantiated object (eg. a Webwork action) can obtain an instance of another (eg. a Manager class) simply by requesting one in its constructor.
What is database in Cucumber?
24, 18 · Database Zone · Tutorial. Like (5) Cucumber is a testing framework that supports behavior-driven development (BDD). It enables us to define the application requirements/behavior in simple English steps. It uses plain meaningful English text using simple grammar defined by a language called Gherkin.
Why is PicoContainer in Cucumber?
Using PicoContainer to share state between steps in a scenario is easy and non-intrusive. All you need is a constructor that requires an object that PicoContainer can create and inject. PicoContainer is invisible.
What is gherkin syntax?
Last updated on January 19, 2022. Gherkin is a plain-text language with a simple structure. It is designed to be easy to learn by non-programmers, yet structured enough to allow concise description of test scenarios and examples to illustrate business rules in most real-world domains.
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 have multiple Then in gherkin?
The Cardinal Rule is a way to break out of the procedure-driven mindset, and banning multiple When-Then pairs per Gherkin scenario is an effective rule for enforcing it.
What is scenario scoped in Cucumber?
A @ScenarioScoped dependecy that is injected by Cucumber into your step classes are always re-created for each scenario. Your job is to make sure you dont have any static fields in the injected dependency. Static fields belongs to the class and not the instance so they are not cleared for each new instance.
What is Cucumber pico container?
What if you wants to create an instance of class without using new keyword or any other way of creating an object and still wants to have object of that class? Then wait here. This library will help you to achieve such kind of requirement.
What are Cucumber test cases?
Cucumber is an open-source software testing tool written in Ruby. Cucumber enables you to write test cases that anyone can easily understand regardless of their technical knowledge.
What is test runner in BDD?
TestRunner File is used to build a Communication between Feature Files and StepDefinition Files. features: We use Cucumber features option to define path of feature file(s). glue: We use Cucumber glue option to define path of step definition file(s).
What are hooks and tagging in BDD Cucumber?
Cucumber supports hooks, which are blocks of code that run before or after each scenario. You can define them anywhere in your project or step definition layers, using the methods @Before and @After. Cucumber Hooks allows us to better manage the code workflow and helps us to reduce the code redundancy.
What are Gherkin keywords?
Gherkin uses a set of special keywords to give structure and meaning to executable specifications. Each keyword is translated to many spoken languages; in this reference we’ll use English. Most lines in a Gherkin document start with one of the keywords.
Why Monochrome is used in Cucumber?
In cucumber, monochrome is used to display console output in color format or not.
How do I run multiple tags in Cucumber?
We can define each scenario with a useful tag. Later, in the runner file, we can decide which specific tag (and so as the scenario(s)) we want Cucumber to execute. Tag starts with “@”. After “@” you can have any relevant text to define your tag like @SmokeTests just above the scenarios you like to mark.
