Software testing for project report .pdfKamal Acharya
Methods of Software Testing There are two basic methods of performing software testing: 1. Manual testing 2. Automated testing Manual Software Testing As the name would imply, manual software testing is the process of an individual or individuals manually testing software. This can take the form of navigating user interfaces, submitting information, or even trying to hack the software or underlying database. As one might presume, manual software testing is labor-intensive and slow.
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.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

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.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

2. Summary
What you will learn in this first section
- Why Testing?
- Causes of software defects
- Tester objectives
- Testing and debugging
- Principles of testing
- Test activities
- Retesting
- Resource triangle
- Completion criteria
- Static and dynamic testing
- Testing independencies
- Code of ethics
3. Why Testing Is Necessary
People make mistakes due
to fallibility but also other
pressures.
i.e.:
- Attention to detail
- Time constraint
- Lack of Knowledge
- Experience
Software (Program Code) is present
everywhere.
From Banking, e-commerce to Cars,
Electrical Appliances, Arms, Heating
Systems and many more.
Failure results in financial loss, waste of
time, loss of reputation or, in worst cases,
injury and death.
Testing reduces the risk of software failure.
4. Causes Of Software Defects
Error: Human make a mistake in code. Development of a document
specification.
Defect: A problem caused by an error.
Fault: A failure of the system or component caused by a defect.
Failure: Failures don’t only happen due to defects, but also environmental
conditions, hardware problems, etc.
All defects start with a human error (for example a typo, misunderstanding, lack planning, capability, etc.)
The tester’s job is to expose the defect by causing a failure before the software gets to production.
5. Objectives Of Testing
Avoid and rectify errors.
Ensure that key functional and non-functional requirements are examined.
Testing is not about removing defects, but about notifying developers about
them.
Testing is also about reducing risk in releasing.
Testing can give confidence in the quality of the software if it finds few or no defects.
Tests can and must be measured.
Typical measurements are:
- Number of defects found
- Number of failures in a given time period (reliability)
- Usability rating
- Maintainability
6. Difference Between Testing And Debugging
Debugging is a process used
to identify causes of bugs in
code and correct them.
Testing is the exploration of
the system in order to find
defects.
Dynamic Testing Debugging
(Developer)(Tester)
Observe failure
Re-test to
confirm failure
no longer
occurs
Investigate and
Isolate defect
Fix defect
Check fix works
7. Fundamental Principles Of Testing
1. Testing shows the presence of bugs.
2. Exhaustive testing (testing all possible data combinations) is impossible.
3. Early testing saves money.
4. Defect clustering happens. If there is a bug in one part of the software, chances are
there are other, related bugs nearby.
5. “The pesticide paradox”: continuing to run the same tests won’t find new bugs.
6. Testing is context dependent. Testing is done differently in different contexts.
7. Software with no known errors is not necessarily ready to be shipped. Does it match
user/business expectations?
8. Five Fundamental Test Activities And Tasks From Planning To Test Closure
Planning - Verify the mission of testing. Planning and
Control
Analysis and
Design
Implementation and
Execution
Evaluating Exit Criteria
and Reporting
Test Closure Activities
Control - Monitor, check progress and take action.
Test analysis and test design is the testing
objectives to create test conditions and test
designs.
Activity where test procedures or scripts are in
order, the environment is setup and tests are run.
Activity where test execution is assessed against
the defined objectives.
Occurs at project milestones such as release,
completion, cancellation or maintenance release has
been complete.
9. Retesting & Regression Tests
Retest - Running the tests again after they fail and the bugs have been in theory fixed.
Regression – Running testing to check the cross impact of defect fix in the whole functionality
or system.
Defect/Bug Raised
Dev Team
Fixed
Test Team
Retest
Regression
Tests
10. Resource Triangle
Time, Cost, and Quality. You can’t have them all, only pick two.
You are given the options of Fast, Good, and Cheap, and told to pick any two. Here Fast refers to the
time required to deliver the product, Good is the quality of the final product, and Cheap refers to the
total cost of designing and building the product. This triangle reflects the fact that the three properties
of a project are interrelated, and it is not possible to optimize all three – one will always suffer. In other
words, you have three options:
Design something quickly and to a high standard, but then it will not be cheap.
Design something quickly and cheaply, but it will not be of high quality.
Design something with high quality and cheaply, but it will take a
relatively longer time.
Fast
(Time)
Cheap
(Cost)
Good
(Quality)
11. Completion Criteria
Criteria you set at the beginning of a project that determines when it is safe to stop testing. Exit
criterion is connected to the test coverage, test case design technique adopted, risk level of the
product varies from one test level to another.
• Specified coverage has been achieved.
• No Showstoppers or critical defects.
• There are very few known medium or low-
priority defects that don't affect the usage
of the product.
• If Exit criterion has not met, the test cannot
be stopped.
• The Exit criterion has to be revamped or the
time should be extended for testing based
on the quality of the product.
• Any changes to the test completion
criterion must be documented and signed
off by the stakeholders.
• The test ware can be released upon
successful completion of exit criteria.
12. Static & Dynamic Testing
Static - Testing where code is not exercised: document specification analysis,
reviews, even code itself, etc.
Can be done as Review by humans carrying out manual examination of
documents or Static Analysis of the code and software models by using
automation tools.
Dynamic - Kind of testing that exercises the program with some test data.
Dynamic testing is performed by executing software under test and comparing
actual and expected results.
13. Testing Independence
Developers are least independent, whereas outsourced testing companies are most
independent, because they don’t take defects as criticism.
Several levels of independence can be defined as shown below:
• Tests designed by the person(s) who wrote the software under test
• Tests designed by another person(s) within the development team
• Tests designed by a person(s) from a different organisational group
(i.e.: an independent test team) or test specialists (i.e.: usability or performance
testers)
• Tests designed by a person(s) from a different organisation or company
(i.e.: outsourcing or certification by an external body)

High
14. Code of Ethics
Involvement in software testing enables individuals to lean confidential and privileged information.
A code of ethics is necessary, the ISTQB® states the following code of ethics:
Public – Testers shall act consistently with the
public interest
Client and Employer – Testers shall act in a manner
that is in the best interests of their client and
employer, consistent with the public interest
Product – Testers shall ensure that the
deliverables they provide (on the products and
systems they test) meet the highest professional
standards possible
Judgement – Testers shall maintain integrity and
independence in their professional judgement
Management – Test managers and leaders shall
subscribe to and promote an ethical approach to
the management of software testing
Profession – Testers shall advance the integrity
and reputation of the profession consistent with
the public interest
Colleagues – Testers shall be fair to and
supportive of their colleagues, and promote
cooperation with software developers
Self – Testers shall participate in lifelong learning
regarding the practice of their profession and shall
promote an ethical approach to the practice of the
profession
