Usability Testing


Usability Testing is a mechanism to test the software application or system on its usage to expose usability defects, ideally this is done by targeted end userswho ultimately are going to utilize the tool and they should be able to accept and also suggest how the tool could be improved for usability. The usability testing focus on the ease to use the application, handling system controls and validating the goals and objectives of the application. This testing is recommended during the early design phase of SDLC, which gives more visibility on the users expectations and system objectives.

Need For Usability Testing

Design and easy access of controls are extremely important for any application. Imagine if you are not able to find the submit button easily to save the data you entered. It will be a big defect on usability. The submit button should be in the obvious position of the screen, and there should be auto-save function to avoid loss of data entered, unable to find necessary controls to take actions etc.

There are many applications / products / websites, which miserably fail, due to following reasons -

  • Process Flow
  • Where do I click next?
  • Which page needs to be navigated? What to expect in the new page?
  • Which Icon or Button represents which Action?
  • Error messages are misleading
  • Loss of Data due to issues, session time or unable to find right controls to save.

How to make software testing successful?

  • Start the testing early during the design and development stages.
  • Testing is not an optional task, rather its as important as design and development.
  • It's always a great idea to learn from competitors by doing usability testing round on your competitor's product before you begin your design and development. This will help in understanding lot Why-How-What scenarios and as well as learning usability mechanisms for your target customers.
  • Select the users from all target departments to test the application(Can be experts/leaders/end-users).
  • Define priorities as you may not have extraordinary time to test all features. We concentrate on frequently used and critical functionalities of the system.


Usability Testing

Planning:

Define the goals and clear tasks of usability testing and the owners of it with expected results. Always connect the goals with the expected results on critical functionalities and objectives of system. Define the testing method, number and demographics of usability testers , test results report mechanism and following same controls for easy consolidation.

Hiring:

Hire the desired number of usability testers as per your test plan. Finding right experience testers who match your requirement both demographically (age, sex etc.) and professionally ( education, job etc.) can take some time.

Defects Reporting:

Findings of the usability tests must be shared with all the stakeholders including developers, product owner, testers, customers, product manager.

Test Analysis:

Data from tests should be thoroughly analyzed to identify actionable recommendations to improve usability of your system.

Accessibility Testing

Accessibility testing is a subset of usability testing. The significance of this testing is to validate both accessibility and usability. Users with physical disabilities test the application using their required helping aids which helps them in operating the tool.

Accessibility Testing

Accessibility aims to cater users of different abilities like:

Visual Impairment Visual Impairment:

A good mix of capacity experience, performance tuning experience and also product development experience.

Physical Impairment Physical Impairment:

Always keep an eye on the customer budget matching their requireetns and specifications so as to provide cost-cutting and time-saving performance testing.

Hearing Impairment Hearing Impairment:

Simulate real world traffic from all targeted geographies with minimal budget.

Cognitive Impairment Cognitive Impairment:

Testers with Learning Difficulties or not able to understand more complex scenarios, the intent is to help them easily navigate through the application.

Security Testing

Security Testing is a mechanism of Software Testing which help uncover any loopholes in the application or in the system that may cause a big data loss. Security testing of any system is about identifying all defects and possibilities of the system which might result into compromising situation of data of organization finances, employee details, critical export control data, personal information or any other business data.

Types of Security Testing

  • This mechanism allows to scan a system in automated way to identify such loopholes against known vulnerability signatures.

  • Identify system and network weaknesses, and provide solutions to reduce these risks. This can be performed manually or through automated ways.

  • Simulate an attack from a hacker. It help analyse the check on potential vulnerabilities to an external hacking attempt.

  • Analysis of security risks observed in the system. Identification of mechanisms to control or reduce the risk associated and these deficiencies are categorized in low, medium and high on the size of its impact if system is compromised.

  • Internal inspection of Applications and Operating systems for security deficiencies. Audit can also be done using code audit tools or can be done manually also.

  • Its hacking mechanism to fool-proof the system from potential security flaws. Unlike malicious hackers , the intent here is to expose security defects in the whole system.

  • A through security readines by auditing Security through various scans, fool-proofing through Ethical Hacking and Risk Assessments to highlight an overall security view and posture of an organization and readiness to prevent malicious attack.
