    • Intention
      The intention of this talk is to
      Present & explain (a selection of) agile test tools to the LU tester´s community
      Show how test tools support the agile tester
       
      The intention is not to 
      give a complete overview of agile testing methodologies and tools.

    • The classic approach
      one phase happens after the other
      testing (test execution) by QA-people is mainly done in only one phase

    • Agile/ Scrum
      Roles in Scrum: Product Owner, Team, Scrum Master
      Testing supports during the whole process, therefore test tools need to handle this

    • Agile/ Scrum
      Special roles (developer, tester, architect, DB admin) aren´t bound to specific people, different people are sharing roles, therefor also testing is a role, that can be filled by everybody
      more people work with the same tool
      tools need to support more aspects then "just" testing

    • Classic vs. Agile
      “Agile teams have particular needs for automated tools that are not well served by traditional record-and-playback GUI drivers.  As requirements specifications, functional tests must be readable: clear, succinct, and expressed in the language of the business domain. As an automated safety net, the tests must be maintainable: built with reusable domain specific testing language components, easy to change as the requirements change.”

    • Classic vs. Agile
      Not a contradiction to "classical approach“

    • Characteristics of Agile Test Tools
      Having tests documented as manual tests and scripted tests is double work
      Waste! 
          
      Use one tool for
      requirements,
      tests,
      automated tests &
      test results

    • Definitions
      TDD - Test Driven Development
      write a (failing) test
      write code to make the test pass
      refactor
      mostly on unit test level
       
      Acceptance Test
      Test to determine if the requirements of a specification are met.
       
      ATDD - Acceptance TDD
      Implementation of a requirement is driven by a set of automated, executable acceptance tests.

    • Definitions
      BDD - Behaviour Driven Development 
      Behaviour-driven development (BDD) is an evolution of test-driven development (TDD) and acceptance-test driven development, and is intended to make these practices more accessible and intuitive to newcomers and experts alike.
      It shifts the vocabulary from being test-based to behaviourbased,andpositions itself as a design philosophy.
      BDD "describes a cycle of interactions with well-defined outputs, resulting in the delivery of working, tested software."

    • Tools
      Two groups (borders are blurred)
      Requirements are described in DSL/ special syntax/ natural language and executed as tests through fixture code.
      Tools for executing tests

    • RSpec
      TDD        
      RSpecsupports in doing the TDD part of BDD, focusing on the documentation and design aspects of TDD.

    • FIT
      FIT is an acceptance testing framework originally developed for Java by Ward Cunningham. One of the central ideas of FIT was to promote collaboration and allow customers and business analysts to write and verify tests. FIT makes it easy to run tests, but does not provide a way to create them. The original idea was to write tests in Word, Excel, or any tool that can output HTML.

      "web-based collaboration tool for software acceptance testing" (http://www.fitnesse.info/fitnesse) 
      "is a web wiki front-end to FIT" 
      Tests are described as tables in a wiki

    • Cucumber
      BDD        
      "Cucumberis a toolthatexecutes plain-textfunctional descriptions as automated tests." (https://github.com/aslakhellesoy/cucumber/wiki/)
      Uses a business-readable DSL
      SUTs in Ruby, Java, .NET, Python, multiple webtestingframeworks... 
      integrates in CI-environments

    • Cucumber
      Describe behaviour in plain text
      Write a step definition in Ruby
      Run and watch it fail
      Write code to make the step pass
      Run again and see the step pass
      Repeat 2-5 until green like a cuke

    • Selenium
      "Selenium is a suite of tools to automate web app testing across many platforms.“
       
      "Selenium...
      runs in many browsers and operating systems
      can be controlled by many programming languages and testing frameworks."

    • Advantages
      Involving tests early in the software lifecycle process 
      No wasted efforts for documenting requirements, test cases & automated tests 
      Creating (automated) regression tests along the way
      Easy to collaborate/ integrate customers Business Experts, POs/PMs
      ...

    • Hurdles to take
      New tool to learn
      Also non technical people need to learn a tool language/ syntax
      Tester need technical skills
      All of the discussed tools should be integrated into the CI system
      Not everything can be tested automatically
      Manual testing is still needed
