HEURISTICS AND MNEMONICS IN SOFTWARE TESTING

 HEURISTICS AND MNEMONICS IN SOFTWARE TESTING


Every tester has technical experience on some stage of his/her professional development. And it is very useful to improve it all the time by new knowledge and technological skills, which not only broaden a professional mind but also fill this mind with some opportunities to understand things, which were misunderstood before.

Discovering various heuristics and mnemonics, a tester can easily broaden his/her view on potential problems inside a developed web product, as well as develop new approaches to the testing directly. Skills in how to use testing heuristics can highly improve the testing efficiency of any product or web component.

CONCEPTS OF HEURISTIC AND MNEMONIC

A process of testing on the basis of heuristics – is a technology of testing algorithms, apps, and programs, and by using it, the testing strategy is based on previous experience and data about the possibility of different events.

Mnemonic – is a set of rules and techniques, which help to remember effectively some necessary information.

Main advantages of testing heuristics:

  • They allow to remember the context, where tested app or product is used actually;
  • Shortness. All heuristics fit easily in the little mindmap, a piece of paper or text file;
  • With the help of heuristics, you can test qualitatively the utilities in a more detailed format;
  • They help to avoid mistakes, made under analogous circumstances during testing of similar software. Philosophy of using the heuristics allows developing special “reminders” on the basis of previous experience – someone’s own one or solutions of other QA specialists.

But for all that, heuristics is a very imperfect method. The main disadvantage of testing heuristics is that heuristic valuation can’t involve the applying of user testing and analysis of real scripts execution. Its results can be very judgmental and baseless from the practical side.


How can the mnemonic system be helpful to software testers?

When testing a new application or within a new and alien context. It’s difficult to know what to focus on. What the unique risks are, and how others have previously solved those same issues. This is where mnemonics can help.

While mnemonics are a learning technique that would be most useful to new testers who want to recall certain testing concepts. They can be also highly valuable to existing software testers who are looking for ways to boost their ability to remember what is important when performing their testing.

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...
