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.
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 -
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.
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.
Findings of the usability tests must be shared with all the stakeholders including developers, product owner, testers, customers, product manager.
Data from tests should be thoroughly analyzed to identify actionable recommendations to improve usability of your system.
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.
Simulate real world traffic from all targeted geographies with minimal budget.
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 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.
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.
