What is cucumber dry-run?

Cucumber dry-run:

• dryRun is one of the command which can be passed in cucumberOptions().
• It is used to check whether all feature files have corresponding steps definitions or not. 
• It will just compile and validate your code/script file.
• If any step definitions not found it will throw message.

dryRun will take 2 values:

False:

• Its default value is false.
• It will compile feature files and throw a message if any step definition(s) not found

True:

• If dryRun value is true, then its glue code execution should be skipped

Demo on Cucumber dryRun:

Let's say I have a sample scenario like below:

cucumber dry run

FirstFeatureFile.feature

Scenario: This is First Scenario
  Given I am in First step with step def implementation in First Scenario
  And I am in Second step without step def implementation

And it's step definitions are:

@Given("I am in First step with step def implementation in First Scenario")
public void iAmInFirstStepWithStepDefImplementationInFirstScenario() {
    System.out.println("Iam in First scenario");
}
In above scenario, Given step have step definition and And step doesn't have step definition.
Run scenario with dryRun option:
Cucumber dryRun=false
Cucumber dryRun=true
