Parallel test execution in Jenkins - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to run two test stages in parallel in Jenkins pipeline.

Jenkins

pipeline {
  agent any
  stages {
    stage('Parallel Tests') {
      steps {
        parallel {
          test1: {
            echo 'Running Test 1'
          },
          test2: [1]
        }
      }
    }
  }
}

C( echo 'Running Test 2' )

D< echo 'Running Test 2' >

💡 Hint

Common Mistakes

Using square brackets [] or parentheses () instead of braces {} for parallel stages.

Forgetting to wrap the steps inside braces.

In Jenkins pipeline, parallel stages are defined as blocks with braces {}. So the correct syntax for the second parallel stage is { echo 'Running Test 2' }.

Complete the code to define parallel stages with names 'Unit Tests' and 'Integration Tests'.

Jenkins

parallel {
  [1]: {
    echo 'Running Unit Tests'
  },
  integrationTests: {
    echo 'Running Integration Tests'
  }
}

💡 Hint

Common Mistakes

Using dashes '-' in stage names which is invalid syntax.

Using uppercase letters at the start which may cause confusion.

Stage names in Jenkins pipeline should be valid Groovy identifiers without special characters or spaces. 'unitTests' is a valid camelCase identifier.

Fix the error in the parallel block by completing the missing keyword.

Jenkins

pipeline {
  agent any
  stages {
    stage('Tests') {
      steps {
        [1] {
          testA: {
            echo 'Test A'
          },
          testB: {
            echo 'Test B'
          }
        }
      }
    }
  }
}

💡 Hint

Common Mistakes

Using 'stages' or 'steps' instead of 'parallel' causes syntax errors.

Omitting the keyword entirely.

The keyword 'parallel' is required to run multiple branches at the same time in Jenkins pipeline.

4fill in blank

hard

Fill both blanks to create a parallel block with two test stages that each run a shell command.

Jenkins

parallel {
  testOne: {
    sh [1] 'echo Test One'
  },
  testTwo: {
    sh [2] 'echo Test Two'
  }
}

C"command"

D'command'

💡 Hint

Common Mistakes

Using single quotes for the argument name causes errors.

Using 'command' instead of 'script' as the argument name.

The 'sh' step in Jenkins pipeline uses the 'script' argument as a string to run shell commands. Double quotes are preferred for Groovy strings.

5fill in blank

hard

Fill all three blanks to define a parallel block with three test stages, each echoing a different message.

Jenkins

parallel {
  testA: {
    echo [1]
  },
  testB: {
    echo [2]
  },
  testC: {
    echo [3]
  }
}

A'Running Test A'

B'Running Test B'

C'Running Test C'

D'Running Test D'

💡 Hint

Common Mistakes

Mixing up the messages between stages.

Forgetting to use quotes around the echo messages.

Each parallel stage should echo its own message. The correct messages are 'Running Test A', 'Running Test B', and 'Running Test C'.
