In a usability-testing session, a researcher (called a “facilitator” or a “moderator”) asks a participant to perform tasks, usually using one or more specific user interfaces. While the participant completes each task, the researcher observes the participant’s behavior and listens for feedback.

The goal of usability testing is to reveal areas of confusion and uncover opportunities to improve the overall user experience.

a. to find out if instructions are complete, accurate, and easy to follow.

The aim is to observe how people function in a realistic manner, so that developers can identify the problem areas and fix them. Techniques popularly used to gather data during a usability test include think aloud protocol, co-discovery learning and eye tracking.

A 5-step process for usability testing

1. Step 1: plan the session. Planning the details of the usability testing session is, in some ways, the most crucial part of the entire process.
2. Step 2: recruiting participants.
3. Step 3: designing the task(s)
4. Step 4: running the session.
5. Step 5: analyzing the insights.

Conducting usability tests before any design decisions are made helps us identify the most important user pain points. By observing how users behave, we can uncover latent needs that people don’t articulate during interviews or surveys.

Report the Findings. If all goes well, after you finish your usability test, it’s time to gather and compare your findings. There is no specific or single method to analyze your data. You can choose and agree with your team on whatever method works for you.

Usability testing is defined as the evaluation of a product by testing it on potential users. If for example, a washing machine brand wanted to test the usability of its product, then it would have to test it on a potential customer.

Top 7 Usability Testing Methods

• Guerilla testing. Guerilla testing is the simplest form of usability testing.
• Lab usability testing.
• Unmoderated remote usability testing.
• Contextual inquiry.
• Phone interview.
• Card sorting.
• Session recording.

Usability testing is the practice of assessing the functionality and performance of your website or app by observing real users completing tasks on it. Usability testing lets you experience your site or app from the users’ perspective so you can identify opportunities to improve the user experience.

Three basic principles underlie usability testing:

• Usability testing permeates product development.
• Usability testing involves studying real users as they use the product.
• Usability testing involves setting measurable goals and determining whether the product meets them.

There are generally four recognized levels of testing: unit/component testing, integration testing, system testing, and acceptance testing. Tests are frequently grouped by where they are added in the software development process, or by the level of specificity of the test.

There are different stages for manual testing such as unit testing, integration testing, system testing, and user acceptance testing. Testers use test plans, test cases, or test scenarios to test a software to ensure the completeness of testing.

Developer vs Tester: Developer always wants to see his code working properly. So he will test it to check if it’s working correctly. To make it fail in any way, and tester surely will test how an application is not working correctly. This is the main difference in Developer Testing and Tester Testing.

Automated testing is significantly faster than a manual approach. Manual testing is time-consuming and takes up human resources. The initial investment in the automated testing is higher. Though the ROI is better in the long run.

Selenium is an open-source web automation tool, currently in demand, and widely used tool in the market. It is one of the best QA automation tools that can automate across multiple OS Like Windows, Mac, and Linux and browsers like Firefox, Chrome, IE, as well as Headless Browsers.

We observed that Agile and DevOps, test automation, artificial intelligence for testing, and API test automation are the most noticeable trends in 2021 and over the next few years too.

The seven principles of testing

• Testing shows the presence of defects, not their absence.
• Exhaustive testing is impossible.
• Early testing saves time and money.
• Defects cluster together.
• Beware of the pesticide paradox.
• Testing is context dependent.
• Absence-of-errors is a fallacy.

The Different Phases of Software Testing

• Requirements Testing.
• Unit Testing.
• System/System Integration Testing.
• Regression Testing.
• Acceptance Tests/User Acceptance Testing.

The order of execution has to be independent between test cases. This gives you the chance to rearrange the test cases in clusters (e.g. short-, long-running) and retest single test cases. In most cases, this makes perfect sense.

Black Box testing has the main goal to test the behavior of the software whereas White Box testing has the main goal to test the internal operation of the system. Black Box testing is focused on external or end-user perspective whereas White Box testing is focused on code structure, conditions, paths and branches.

3: Out of the following which one describes the major benefit of verification early in the life cycle? A. It allows the identification of changes in user requirements.

In software engineering, test design technique is a procedure for determining test conditions, test cases and test data during software testing. Test design techniques always include test selection criteria determining when to stop designing more test cases.
