Risk Storming

Risk Storming for Vending Machine

Risk-storming is a quick technique that provides a collaborative way to identify and visualize risks. As an aside, this technique can be used for anything that you can visualize; from enterprise architectures to business processes and workflows. It can be used at the start of a software development project (when you're coming up with the initial software architecture) or throughout, during iteration planning sessions or retrospectives. Just make sure that you keep a log of the risks that are identified, including those that you later agree to have a probability or impact of "none".



Riskstorming is a collaborative, strategic board game that focuses on identifying how to test risks that impact the imperative quality aspects of your product.

A RiskStorming session takes you through 3 phases to get answers to these questions:

  1. Which quality aspects matter most for your product?
  2. Which risks endanger those quality aspects?
  3. How do we test to make sure those risks don’t happen?

Accessibility

1, A person with dyslexia can access to use a machine - Personas techniques
2, A person with a wheelchair can reach a machine for access to put money. - Personas Techniques
3. Blind person can able to access the machine - Personas Techniques








Functionality
1, The vending machine drops the product correctly what we press the number - Unit testing
2, can we choose more than one item of food/drink?       - Unit testing
3, Keypad works properly when we choose product  - Integration testing
4, Machine can access coins and cash correctly - Boundary testing
5, Vending machine can access credit card - Integration testing



Performance Testing
  1, How many transactions can handle every day? - Stress Testing
 2,  How long vending machine takes time to access money and drop a drink/food- Risk analysis
3, how many drinks/food can order at a time? - Stress testing

Security testing- 
1, User credentials should be secure if they use a credit card -  Social Engineering
2, Is the Machine secured with cash?           - Risk analysis


I have learned it really interesting and start thinking about actual testing about the product. Thanks, Miss Beth Marshall for teaching us software fundamentals in Bootcamp sessions.

Exploratory testing & SBTM

Image
 Exploratory Testing  Exploratory testing is also known as ad hoc testing and was known solely by this term until the early 1990s when a group now called the “Context-Driven School” started using the term exploratory.  Cem Kaner  was the person that coined the term Exploratory Testing in his book “Testing Computer Software” and described it as: “Simultaneous test design, test execution and learning with an emphasis on learning” According to the different site, I found different definitions for exploratory testing- In exploratory testing, testers do not work on the basis of previously created test cases. They check a system without a plan in mind in order to discover bugs that users may face when navigating a website or app without a specific aim or direction in mind. Exploratory testing” – as the name suggests, is simultaneous learning, test design, and test execution process. We can say that in this testing test planning, analysis, design, and test execution, a...

Accessibility testing tool - Bootcamp

Image
                                  Wave Accessibility tool WAVE is a web accessibility evaluation tool developed by WebAIM.org. It provides visual feedback about the accessibility of your web content by injecting icons and indicators into your page. No automated tool can tell you if your page is accessible, but WAVE facilitates human evaluation and educates about accessibility issues. All analysis is done entirely within the Chrome browser allowing secure valuation of intranet, local, password protected, and other sensitive web pages. To run a WAVE report, simply click on the WAVE icon to the right of your browser address bar, or select "WAVE this page" from the context menu. Steps to verify the accessibility of the website Step #1)  Click on URL: http://wave.webaim.org/ Step #2)  Enter the  Web page address  in the  text   box  and hit enter. Example. So enter the sit...

API Tresting - DAY 1

Image
  30days of API testing challenges -  Define what API testing is, share your definition on The Club API - stands for the application programming interface. They are basically a collection of functions and procedures, which allows us to communicate two applications or libraries.   What is API Testing? API TESTING  is a software testing type that validates Application Programming Interfaces (APIs). The purpose of API Testing is to check the functionality, reliability, performance, and security of the programming interfaces.  API -Let's explain each of these terms to better understand: - " Application ": An application is a service accessible by a human or computer program. Ex: Facebook is a social network application, Spotify is an audio streaming application, PlanningPME a planning application. - " Programming ": a program is a set of computer functions written by a developer who performs tasks in his place. Ex: If I want to transform postal addresses i...
