Usability Testing Interview Questions & Answers

Introduction

Usability testing is a testing methodology in which the software or application is handed over to the user and he tests it by using it. The customer is asked to check that whether the system is as per his requirement or not. The best way to test or check the software or application usability is to provide him the prototype of the software even in initial stages and ask them to test that whether it is as per their requirement or not.

Usability Testing Interview Questions Answer for Fresher

Q1). How can you define the Usability Testing?

Usability testing is associated with testing of software usability. Usability testing is a testing methodology in which the customer is asked to test the usability of the software. It can be performed either by providing software prototype to the customer and ask them to test its various features and functions. Like if it is a login module then the user will check that whether there is forgot password link available or not.

Q2). How is Usability Testing related to the functional testing?

Functional testing is just a black box testing in which the application functionality is tested and the certain input is provided to test whether the desired output is being generated or not. Through such testing, not only the application behavior is tested but it will also check either the application is as per user requirements or not. Moreover, it is also tested that whether the application can be released to live environment or not?

Functional testing can be of the following types:

3). List the steps that are covered as part of usability testing.

While conducting usability testing, below listed steps must be covered as part of testing:

• Determine the actual output produced by the application by giving input to the application.
• Understand the SRS or software requirement specification and clear the doubts in the form of reviews.
• Execute test cases and determine that whether the application behavior is appropriate and as per user requirement or not.
• Compare the actual and expected outcome

Q4). What is the difference between build and release?

Build and release are two separate terms that are associated with the software. These terms can be defined as below:

Build: Software build is an executable file that is basically handed over to the tester by the development team. Through this executable file, the tester can test the implemented functionality of the application for any bug or fixes. If the software build does not pass the critical checklist that has the major part of application functionality then it can be rejected by the testing team.

As far as software release is concerned, this is the stage when the software application is no longer in the testing phase, then it is named as release cycle. A software release can have more than one build. When the application is handed over to the user after completion of development and testing then it is called the software release.

Q5). What do you understand by bug status in case of usability testing?

Bugs are the errors that are found in the software application. They can be in various states and of many types.

Q6). Give the different types of bug status?

Main types of software bugs are listed below:

• New: When a bug is identified for the first time, it is said as a new bug.
• Assigned: When a tester logged a bug, it is reviewed by the leader of the testing team and is assigned to the corresponding member of the development team.
• Open: When a tester logs into any bug, it is assumed in open state and the time until the developer fixes the bug it remains an open state.
• Fixed or Resolved: When a bug is completely resolved by the developer, means the time when the application starts producing the desired output for any particular issue, then at that time developer changes the bug status from open to resolved or fixed.
• Closed or Verified: When a developer changes the bug status from open to fixed or resolved then tester again tests the application for the bug and if it gets fixed then he changes the bug status to Closed or Verified.
• Reopen: If a bug is reproduced by the tester means even after bug fixing done by the developer, but still, it exists then its status is marked as ‘reopen’ by the testers.
• Invalid or Not a Bug: If a reported bug or issue is as per the functionality and is logged just due to misinterpretation then it is called an Invalid bug.

Q7). What is Data-driven testing? Is it related to usability testing too?

When a series of test cases are executed repeatedly like XML file, SQL database or CSV file then it is called data-driven testing. The output or actual values are compared with the expected ones to verify the result. Yes, because in the case of usability testing we need to work on data to check website behavior, brand perception, validate data etc.

Q8). What are the benefits offered by the data-driven testing?

It offers the following advantages:

Q9). Explain the important and considerable points to write usability test cases.

Most important activity and part of the test execution process is to write the proper test cases, it requires complete knowledge of the application and good writing skills. The Tester can consider below-listed points while writing usability test cases:

• You should have a proper understanding of client requirement before writing test cases. The Tester must not assume anything and must clear all the doubts that are related to client requirement.
• Requirements must be included in test cases. For this, the traceability matrix is used to check every requirement. No requirement must be left out while writing the test case.
• Test cases should be checked in repetition time to time
• While writing test cases priority should be checked and assigned for every test case. They must be executed as per their priority, for this firstly tests the modules that have higher priority, and basic functionality, after that medium or low priority test case must be executed.
• For a specific release the test cases must be built Sprint wise, so that developer can analyze product quality based on the test case execution.
• Test case structure must be simple and easy to understand, moreover input test cases values must not be limited and lie in a wide range.

Q10). What is Automation Testing? Can usability testing be automated?

When automatic tools are used to execute the test case suite just to increase test coverage and speed up test execution, then it is known as Automation testing. No human intervention is required in automation testing, as pre-scripted test cases are used to compare the outcomes of previous test cases. Yes, we can automate the usability testing with the help of test cases that can be executed repeatedly to check the product behavior.

Automation testing is advantageous as it offers accuracy, ease of use and great consistency. Some of the popular tools of automation testing are:

11). Explain Load Testing and Stress Testing.

These are two functional testing that can be defined as:

Stress Testing: It is a performance testing, where the application is tested for stress or execution that means that it is tested above the threshold of the break and the point where the application gets broken is determined. When there are huge data and the number of users then it can arise. During the stress test, the application recovery time is also determined when the load gets reduced.

Load Testing is also a type of performance testing, in this testing, the application is executed above various levels of load and the peak performance of the application is monitored on the server along with server throughput, response time, etc. Application integrity, performance and process stability are determined under concurrent system load in this testing.

Q12). Explain the volume testing.

Volume testing is also a type of performance testing in which server throughput and response time is determined when concurrent users are there and data load is large from the database, and the application is put under tests.

Q13). Explain different types of Usability Testing.

Below listed two types of usability testing is used in testing:

• Requirement Based Testing: When the requirements are prioritized and then the testing is performed when it is known as performance testing. All critical test paths must be included in the test cases.
• Business Process Based Testing: This form of functional testing is performed from the business process perspective. For this, it is must to have the business knowledge.

Q14). What are the benefits of usability testing for website owners?

Well, it is highly important for websites because it checks the complete behavior and validates the input and the output. It will check either the home page is working as per the expectations or not. If there is something missing then it is immediately informed to the website developers.

Q15). What is the major benefit of usability testing for businesses?

It gives compelling evidence of which elements are working perfectly on your website what needs to be fixed. Also, it will provide a compelling optimization strategy to make sure that everything is in place.
