p-unit

Overview

A Groovy library (based on JUnit - https://github.com/junit-team/junit, and Groovy SSH DSL - https://github.com/aestasit/groovy-ssh-dsl) for creating integration tests of provisioning results of Puppet modules, Chef cookbook, Ansible playbooks and other.

The p-unit is designed to work with some virtualization or cloud solutions, which allow starting testable server instances on-demand. Aestas/IT usually uses p-unit together with gramazon (https://github.com/aestasit/gramazon) - a Groovy library and Gradle plugin for working with Amazon EC2 instances.

Quick example

The following code shows an integration test for simple JDBC driver installation module:

class JdbcInstallTest extends BasePuppetIntegrationTest {
      
  @Test
  def void verifyMySqlDriverIsDownloaded() {
    
    apply("""
      jdbc::install { 'mysql':
        media_library_host => '$mediaLibraryHost' 
      }
    """)

    assertTrue directoryExists("/opt/jdbc")
    assertTrue fileExists("/opt/jdbc/mysql-connector-5.1.23-generic-noarch.jar")
    
  }

  @Test
  def void verifyDerbyDriverIsDownloaded() {
    
    apply("""
      jdbc::install { 'derby':
        media_library_host => '$mediaLibraryHost' 
      }
    """)

    assertTrue directoryExists("/opt/jdbc")
    assertTrue fileExists("/opt/jdbc/derby-driver-10.9.1.0-generic-noarch.jar")
    
  }
        
  @BeforeClass
  def static void installTools() {
    command('yum -y -q install tree')
  }

  @Before
  def void cleanUp() {
    println "Removing installation directories:"
    command('rm -rf /opt/jdbc')
  }

  @After
  def void debug() {
    println "Checking directory content:"
    command('tree -ad /opt/jdbc')
  }
  
}
