Agile testing principles and practices - Anil KaradeIndicThreads
Traditional test processes are not adaptive to extensive changes in software. Agile process emphasizes on ability to adapt to changing business needs, customer collaboration, integrated teams and frequent delivery of business values. Agile is an umbrella term that describes a variety of methods including XP and Scrum.
The talk will discuss pitfalls of the traditional testing process. Traditional testing process happens very late in the SDLC Where as Agile process focuses on test-first approach. The talk will explain benefits of going agile. Principles and practices of agile process will be discussed and agile methodologies Scrum and Extreme Programming will be discussed in detail. Purpose of Scrum, its effectiveness, timings and managing the scrum will be discussed. Some of the practices for XP like Pair Programming, Test Driven Development will be discussed. The Talk will also cover the QA role in agile world. The talk will cover the implementation issues while shifting from traditional to agile process.

Agile Testing Methodology- Principles of Agile Testing Methodolgy Mobcoder
The agile testing methodology has been a requirement in the software development lifecycle. It must be supported by more customer engagement and test code once it is viable in the system. The code must be clean and efficient enough to pass system review. Many companies have implemented agile testing. Names like Cisco, IBM, and JP Morgan Chase are just a few. Agile testing is a great way to increase your competitive advantage, even if it has not been implemented yet.
Its a simple presentation show you new concepts of software development like waterfall, agile and scrum also in testing like test driven development "TDD"
This session will focus on a Agile Testing and provide you with practical examples and techniques to help your team understand what is behind this approach.
New to Agile? Having challenges implementing an agile process in your organization? Have you been using Scrum, but need to bend the rules to make it work in your organization? Can’t get the business to “buy-in”? Come and learn about implementing an agile process in your organization. You'll look at the “buffet table” of agile processes and procedures and learn how to properly decide “what to eat.” We’ll start by defining XP, Scrum, Kanban and some other popular methodologies and then learn how to mix and match each process for various scenarios, including the enterprise, ISVs, consulting, and remote teams. Then take a look at agile tools and how they will aid in implementing your development process. You’ll see how Microsoft Team Foundation Server 2010 provides process templates for Agile that facilitate better planning and metrics. Learn how Microsoft’s application lifecycle management (ALM) tools can support your development process. Lastly, we will talk about how to “sell” agile to your business partners and customers. The speakers have a very interactive style so participation is encouraged and there will be plenty of time for Q&A.
Unlike the Waterfall method, Agile Testing can begin at the start of the project with continuous integration between development and testing.
Agile Testing methodology is not sequential (in the sense it’s executed only after coding phase) but continuous.
Agile is an iterative development methodology, where requirements evolve through collaboration between the customer and self-organizing teams and agile aligns development with customer needs.
The word Agile signifies something that can be performed quickly and immediately ,in the area o f software development
What is Agile Methodology?
AGILE methodology is a practice that promotes continuous iteration of development and testing throughout the software development lifecycle of the project. Both development and testing activities are concurrent unlike the Waterfall model
To be able to effectively and sustainably test in Agile projects the test activities must be properly integrated in the Agile approach. To be efficient and effective automation is essential. In this webinar Rik will cover subjects like Footholds for testing from the Manifesto, the role of Product Owner, Scrum Master and Agile team members, Test Strategy and Test Levels (e.g. E2E-testing), TMap & ISTQB (Agile Extension) and DevOps.
Key Takeaways:
1) Be adaptive
2) Use a risk-based approach
3) Testing activities must be automated as much as possible

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

FA-1.1.3 (K2) Understand the benefits of early and frequent feedback
ISTQB CTFL Agile Tester 10 November 17, 2014
11. Agile Testers Work Differently
Testers must understand the values and principles that underpin Agile
projects.
Testers are an integral part of a whole-team.
Members in an Agile project communicate with each other early and
frequently, which helps with removing defects early and developing a
quality product.
ISTQB CTFL Agile Tester 11 November 17, 2014
12. Agile Manifesto
In 2001, creators of most widely
used lightweight SW
development methodologies
agreed on a common set of
values and principles (Agile
Manifesto).
ISTQB CTFL Agile Tester 12 November 17, 2014
13. Agile Principles
From the manifesto, 12 guiding principles were created.
They form the foundation on which all agile methods are created.
ISTQB CTFL Agile Tester 13 November 17, 2014
14. Whole Team Approach
Involves everyone with the knowledge and skills necessary to ensure
project success
Includes customer representatives and business stakeholders who
determine product features
3 – 9 members
Co-located
Daily stand-up meetings
ISTQB CTFL Agile Tester 14 November 17, 2014
15. Whole Team should be Cross
Functional
ISTQB CTFL Agile Tester 15 November 17, 2014
16. Power of 3
The whole team is involved in any consultations or meetings in which
product features are presented, analyzed, or estimated.
Involving testers, developers, and business representatives in all feature
discussions is known as the power of three.
ISTQB CTFL Agile Tester 16 November 17, 2014
17. Why Whole Team Approach?
Promotes more effective and efficient team dynamics
Enhancing communication and collaboration within the team
Enabling the various skill sets within the team to be leveraged to the
benefit of the project
Making quality everyone’s responsibility
ISTQB CTFL Agile Tester 17 November 17, 2014
18. Example: Tester Work with Others to
Achieve Desired Quality Levels
Supporting and collaborating with business representatives to help them
create suitable acceptance tests
Working with developers to agree on the testing strategy, and deciding on
test automation approaches
Testers can thus transfer and extend testing knowledge to other team
members and influence the development of the product.
ISTQB CTFL Agile Tester 18 November 17, 2014
19. Early and Frequent Feedback
Iterations
in Agile
Projects
Early &
Continuous
Feedback
Continuous integration is a way to provide rapid feedback.
In sequential approach, customer often see the product when the project
is nearly completed.
Too late to address customer issues effectively
ISTQB CTFL Agile Tester 19 November 17, 2014
21. By Getting Frequent Customer
Feedback, Agile Teams
Can incorporate most new changes
Focus on the features with the highest business value, or associated risk,
and these are delivered to the customer first
Are managed better since the capability of the team is transparent to
everyone
ISTQB CTFL Agile Tester 21 November 17, 2014
22. Early and Frequent Feedback Benefits
Avoiding requirements misunderstandings, which may not have been
detected until later in the development cycle when they are more
expensive to fix.
Clarifying customer feature requests, making them available for customer
use early. This way, the product better reflects what the customer wants.
Discovering (via continuous integration), isolating, and resolving quality
problems early.
Providing information to the Agile team regarding its productivity and
ability to deliver
Promoting consistent project momentum.

36. XP Rules cont’d
Testing
• All code must have unit
tests.
• All code must pass all unit
tests before it can
be released.
• When a bug is found tests
are created.
• Acceptance tests are run
often and the score
is published.
ISTQB CTFL Agile Tester 36 November 17, 2014
41. Scrum
An iterative, incremental methodology for project management.
Scrum (as opposed to XP) does not dictate specific SW development
techniques (e.g., test first programming).
In addition, Scrum does not provide guidance on how testing has to be
done in a Scrum project.
Scrum is composed of:
2 Backlogs
5 Time boxes
Definition of done
3 Roles

44. Kanban (Visual Card or Board)
A management approach sometimes used in Agile projects
In a value-added chain, Kanban is used to:
Manage the work in progress visually on a board
Optimize the work by limiting the work in progress to match the team
throughput (WIP limit)
ISTQB CTFL Agile Tester 44 November 17, 2014
45. Kanban Board
Each column shows a station (a set of related activities)
Items to be produced or tasks to be processed are symbolized by tickets
moving from left to right across the board through the stations.
ISTQB CTFL Agile Tester 45 November 17, 2014
46. Work-in-Progress Limit and Lead Time
WIP limit is a limit of parallel activities controlled by max number of
tickets allowed for a station.
Whenever a station has a free capacity, it pulls tickets from the previous
one.
Lead time for the complete value stream minimization is main objective of
Kanban by optimizing the continuous flow of tasks.
ISTQB CTFL Agile Tester 46 November 17, 2014
47. Kanban vs. Scrum
In both, visualizing active tasks provides transparency of content and
progress of tasks.
Tasks not yet scheduled are waiting in a backlog and moved onto the board as
soon as there is new space (production capacity) available.
Iterations or sprints are optional in Kanban.
Allows releasing its deliverables item by item, rather than as part of a release
Timeboxing as a synchronizing mechanism is optional.
ISTQB CTFL Agile Tester 47 November 17, 2014
48. Poor Specifications
A major reason for project failure
They result from users’ lack of
insight into their true needs,
absence of a global vision for the
system, redundant or
contradictory features, and other
miscommunications.
Specifications are poor when the
vision of a feature is not shared
among developers, testers and
business representatives.
Lacks the power of 3
ISTQB CTFL Agile Tester 48 November 17, 2014
49. Power of 3 is Achieved by
In Sequential Development
By formal reviews
After requirements are written
In Agile Development
By informal reviews
While requirements are written
In the form of user stories
That capture requirements from the
prospective of:
Developers
Testers
Business representatives
ISTQB CTFL Agile Tester 49 November 17, 2014
50. User Stories
Document minimal requirements
Functional & non-functional
Should include acceptance
criteria defined in collaboration
between business
representatives, developers, and
testers
Acceptance criteria extend vision
of developers/testers about the
feature that business
representatives will validate.
ISTQB CTFL Agile Tester 50 November 17, 2014
51. Testers Improve User Stories
Identifying missing details or non-functional requirements
Asking business representatives open-ended questions
Proposing ways to test the user story
Confirming the acceptance criteria
Collaborative authorship of the user story can use brainstorming and mind
mapping.
Testers may use the INVEST technique to assess a user story.
ISTQB CTFL Agile Tester 51 November 17, 2014
52. INVEST
Created by Bill Wake as a reminder of the characteristics of a good quality
user story.
ISTQB CTFL Agile Tester 52 November 17, 2014
53. A User Story is the Conjunction of
3C’s
ISTQB CTFL Agile Tester 53 November 17, 2014
54. Retrospective
A meeting held at the end of each
iteration/increment
To discuss:
What went well?
What can be improved?
How to improve?
If regularly conducted with
appropriate follow up, they are
critical to self-organization and
continuous improvement.
ISTQB CTFL Agile Tester 54 November 17, 2014
55. Too Many to Improve
Retrospectives can improve test effectiveness, test efficiency, test cases
quality and team satisfaction.
Retrospectives can address testability of applications, user stories,
features or system interfaces.
RCA can drive and decide improvements.
Few improvements per iteration == Continuous improvement @
sustainable pace == Adaptive Agile method
ISTQB CTFL Agile Tester 55 November 17, 2014
56. Retrospective Organization
Agile method dependent
Attended by team (testers are part of team) + business representatives
Testing occurs every iteration and vital to team success.
Testers should bring testing prospective into retrospectives.
Facilitators organize and run retrospective meetings.
Team may invite other participants
ISTQB CTFL Agile Tester 56 November 17, 2014
57. Retrospective KSF’s
All participants can provide input on any activity
An agreement must be done when anything can be discussed outside a
retrospective.
Mutual trust within the team
Professional environment
It is about improvement not personal attacks.
Retrospective is a kind of review. Its KSF’s are same those of reviews.
ISTQB CTFL Agile Tester 57 November 17, 2014
58. Need for Continuous Integration (CI)
Delivery of a product increment requires reliable, working, integrated SW
at the end of every sprint (increased risks).
CI aims at merging and integrating changes @ least once a day.
CM, compilation, SW build, deployment, and testing are wrapped into a
single, automated, repeatable process (decreased risks).
Defects are detected more quickly.
ISTQB CTFL Agile Tester 58 November 17, 2014
59. CI Activities (Automated and Daily)
Static Code Analysis
Compile
Unit Test
Deploy
Integrate Test
Report
ISTQB CTFL Agile Tester 59 November 17, 2014
60. Good CI
Allows Agile testers to run automated tests regularly to send quicker
feedback about code quality to team
Visualizes test results to all team members by integrating reports
Its automated regression tests covers as much functionality as possible,
including user stories delivered in the previous iterations
Supports building large integrated systems
Manual tests can be focused on new features, changes and confirmation
testing.
ISTQB CTFL Agile Tester 60 November 17, 2014
61. CI Needs Build Tools
To run unit and integration tests
To run additional static and dynamic tests
To measure and profile performance
To extract and format documentation from the source code
To facilitate manual quality assurance processes
ISTQB CTFL Agile Tester 61 November 17, 2014
62. CI Needs Build Tools cont’d
Can be linked to automatic
deployment tools (can fetch build
from CI/build server and deploy it
into one or more environments)
This continuous application of QC
improves product quality and
reduces delivery time by
replacing the traditional practice
of applying quality control after
completing all development.
ISTQB CTFL Agile Tester 62 November 17, 2014
63. CI Benefits
Earlier detection and easier RCA of integration problems and conflicting
changes
Regular and quick feedback on code and improvement decisions
Keeps the version of SW being tested in a day of the version being
developed
Reduces regression risk associated with refactoring and schedule risks
associated with big-bang integration
Provides confidence
Visualizes product increments progress
Encourages developers and testers
Constant availability of executable SW throughout the sprint for testing,
demonstration, or education purposes
Reduces repetitive manual testing activities
ISTQB CTFL Agile Tester 63 November 17, 2014
64. CI Risks and Challenges
CI tools have to be introduced and maintained.
CI process must be defined and established.
Test automation requires additional resources and can be complex to
establish.
Test coverage is essential to achieve automated testing advantages.
Teams sometimes over-rely on unit tests and perform too little system and
acceptance testing.
ISTQB CTFL Agile Tester 64 November 17, 2014
65. CI Tools
Testing tools, build automation tools and version control tools
ISTQB CTFL Agile Tester 65 November 17, 2014
66. Agile Planning
Planning in ongoing
In Agile lifecycles, there are 2 types of planning:
Release planning
Iteration planning
ISTQB CTFL Agile Tester 66 November 17, 2014
67. Release Planning
Looks ahead to the release of a product
Often a few months ahead of the start of a project
Defines/re-defines the product backlog
May involve refining larger user stories into smaller ones
Business representatives with team establish/prioritize user stories for the
release
Basis for a test approach and test plan spanning all iterations
Based on these user stories, project and quality risks are identified and a
high-level effort estimation is performed.
Release plans are high-level.
ISTQB CTFL Agile Tester 67 November 17, 2014
68. Testers in Release Planning
Defining testable user stories, including acceptance criteria
Participating in project and quality risk analyses
Estimating testing effort associated with the user stories
Defining the necessary test levels
Planning the testing for the release
ISTQB CTFL Agile Tester 68 November 17, 2014
69. Iteration Planning
After release planning for iteration 1
Looks ahead to an iteration end and concerned with iteration backlog
Team selects user stories, elaborates them, performs risk analysis on them and
estimates the work needed for them.
A user story can be refused by the team if vague and the business
representatives fail to clarify it.
Number of stories selected depends on established team velocity and size of
selected user stories.
Selected stories are broken into tasks carried out by the team in an iteration.
ISTQB CTFL Agile Tester 69 November 17, 2014
70. Testers in Iteration Planning
Participating in the detailed risk analysis of user stories
Determining the testability of the user stories
Creating acceptance tests for the user stories
Breaking down user stories into tasks (particularly testing tasks)
Estimating testing effort for all testing tasks
Identifying functional and non-functional aspects of the system to be tested
Supporting and participating in test automation at multiple levels of testing
ISTQB CTFL Agile Tester 70 November 17, 2014
71. Release and Iteration Planning
Address Test Planning
Testing scope (extent of testing and test goals)
The team members who will carry out the test activities.
Test environment and data needed (when need and expected changes)
Scheduling functional and non-functional test activities (frequency,
dependency and relation to development activities)
Project and quality risks to be addressed
In addition, team estimation should consider time and effort needed to
complete the required testing activities.
ISTQB CTFL Agile Tester 71 November 17, 2014
72. Re-Planning Releases and Iterations
Releases and iterations may change (adaptability).
Release re-planning changes due to changes in individual user stories by
internal or external factors.
Internal factors: delivery capabilities, velocity or technical issues
External factors: new markets/opportunities, competitors or threats
Iteration re-planning can change cause of a user story wrongly estimated
as simple but proven to be more complex.
ISTQB CTFL Agile Tester 72 November 17, 2014
73. Re-Planning Challenges Testers
Understanding the big picture of a release for test planning purposes
Having adequate test basis and test oracle in each iteration for test
development
Embracing changes
Decisions about test strategies/documentation
