Question

What is regression testing?

Answer 1

Regression testing is done to check the performance of the application after it is updated or modified. This testing process is crucial because it verifies that changes made to the code have no errors or bugs that impact the performance of applications. This software testing is done either manually or by using Automated tools. Regression testing is useful as it is faster and displays fewer errors than manual testing. Also, regression testing is more expensive to implement.

Answer 2

Application testing is a testing approach that verifies the application's performance as expected. This software testing is done in two ways: manually or by utilising Automated testing tools.

Here we highlighted various types of testing mechanisms. Let's discuss each of them:

Functional testing is a testing approach that verifies the application's performance as expected. This software testing is done by writing test cases or using Automated tools. It is implemented to verify that the application fulfils all the function specifications.

Load testing is done to verify that the application can endure the expected load. It is done by implementing the test cases with multiple users. This software testing is done in two ways: manually or by utilising Automated testing tools.

Answer 3

Functional testing tools: Functional testing is implemented to verify that the application fulfils all the function specifications.Examples: QuickTest Professional, Selenium, and Rational Functional Tester.

Regression testing tools: This testing process verifies that changes made to the code have no errors or bugs that impact the performance of applications. Examples are Winrunner, Rational Robot and SilkTest

Load testing tools: Load testing is done to verify that the application can endure the expected load. Examples: LoadRunner, WebLoad and JMeter.

The tool depends on the type of software application being tested and your budget. Automated application testing tools are generally more costly than manual testing.

Answer 4

API functional testing is a process of testing an application to verify the performance of the API as expected. It is done by testing the application's responses to input values, fixing bugs, and additional functionality. API functional testing confirms that API functions as expected before launching in the market.

Some examples of API functional testing tools are API Fortress, SoapUI, and Postman. These tools design test cases to determine the expected outcomes.

Answer 5

Usability Testing is a type of approach to check user interaction with the application. It is done to ensure that application provides optimum user experience.

There are many types of usability testing. Let's discuss each of them:

Black-Box Testing: In this type of testing approach, application testers check the functionalities of the application from the user end. Furthermore, testers are not familiarised with the internal functions of the applications.

Gray-Box Testing: In this type of testing approach, application testers check the functionalities of the application from both user's and developer's end. Furthermore, testers are familiar with the internal operations of the application.

White-Box Testing: In this type of testing approach, application testers check the functionalities of the application from the developer's end. Also, testers have a comprehensive understanding of internal operations.
