Module A

Class B

End

b= A::B.New

Q7. What Are Hooks In Cucumber?

Hooks are Cucumber's manner of taking into account setup to be carried out previous to checks being run and teardown to be run in a while. They are described as executable Ruby blocks, much like JUnit methods marked with @Before, @After annotations. Conventionally they're positioned below aid/, and are applied globally. Three fundamental styles of hooks exist.

Before - Runs before a situation

After - Runs after a scenario

Q15. What Is Gherkin Language?

Gherkin is the language that Cucumber uses to define take a look at instances. It is designed to be non-technical and human readable, and collectively describes use cases referring to a software device.

The motive at the back of Gherkin's syntax is to promote Behavior Driven Development practices throughout an entire improvement crew, inclusive of commercial enterprise analysts and executives.

Q16. Define Cucumber Report?

Q17. Define What Is Scenario Outline ?

Scenario outline is used to execute the identical scenario with unique check statistics.

We can upload test facts in examples phase

Q18. How Does Cucumber Works With Browser Automation?

Cucumber does not provide constructed in browser automation. However, it does paintings well with existing gem stones which includes Selenium and WATiR-WebDriver.[24] It does assist running checks with transactions through leveraging different gem stones together with ActiveRecord.

Q19. Define What Is Error Handling And Define How Do You Do Error Handling?

P584: Raise, Rescue

Q20. Define What Are The Keywords That We Use In Cucumber Scenario Steps ?

We use Given,when,Then,And and But keywords in cucumber situation steps .

Q21. Explain Define What Is Scenario Outline In Feature File?

Scenario Outline: Same situation can be executed for more than one sets of information using scenario define. The records is provided through a tabular shape separated by (I I).

Q22. What Is A Scenario In Cucumber?

Each Feature is made from a set of eventualities. A unmarried situation is a waft of activities thru the Feature being described and maps 1:1 with an executable take a look at case for the device.[18] Keeping with the example ATM withdrawal feature, a state of affairs might describe how a person requests cash and what happens to their account.

Q23. What Is Cucumber Tool?

Cucumber is a software device utilized by pc programmers for trying out other software. It runs automated reputation exams written in a behavior-driven development style. Central to the Cucumber BDD method is its simple language parser referred to as Gherkin.

Q24. Explain Define What Is Test Harness?

A test harness for cucumber and rspec lets in for separating duty among putting in place the context and interacting with the browser and cleaning up the step definition files

Q25. What Are Tags In Cucumber?

Gherkin's Feature shape forces business enterprise. However, in cases wherein this default organization is inconvenient or inadequate, Gherkin provides Tags. Tags are @-prefixed strings and can be located earlier than.

Feature

Scenario

Scenario Outline

Examples: An element can have multiple tags and inherits from figure elements.

Q26. Define What Is Cucumber Dry Run ?

Cucumber dry run is used to collect cucumber function documents and step Definitions. Of there's any compilations mistakes it will Define How whilst we use dry run
