Functional testing
Functional testing is a quality assurance (QA) process and a type of black-box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (not like in white-box testing). Functional testing usually describes what the system does.
What is non functional testing in software testing?
Non-functional testing is testing designed to check a software application's non-functional aspects such as performance, reliability, utility, etc. In addition, this testing is designed to test a system's readiness related to non-functional parameters typically never addressed by the functional testing process.
What is a functional test case?
A functional test case assigns the testing of a function or feature in order to see if it produces the expected result. Every new feature and function must be tested before release, and most need to be continuously tested. For example, you might test a photo upload feature. When you add a photo, does it get added to the digital asset library?
Should non-functional testing be measurable or subjective?
Non-functional testing should be measurable, so there is no place for subjective characterization like good, better, best, etc. Exact numbers are unlikely to be known at the start of the requirement process Ensure that quality attributes are identified correctly in Software Engineering.

What are the different types of testing?
Software Testing Types. In general, there are three types of testing−. Functional. Non-Functional. Maintenance. There are several testing levels in all categories of testing, but they are commonly referred to as Testing Types. The above definition can vary slightly in various books and study guides.
What is functional testing?
Functional Testing is the part of Automation testing. The primary goal of functional testing is to validate the functionalities or to check all functionalities are properly working not as per user requirements. Functional testing is done as per the user concern and trying to make it as user want. Functional Testing involved black box testing.
Why is functional testing important?
In the functional testing tester first test each component’s functionality, not the structure to confirm desired output. Functional testing continues throughout the development cycle and into production. Functional testing is very important in Software Testing.
What happens when a bug is reported to the testing team?
So now the bug is reported by the testing team to the developer team to fix it. When the developing team fixes the bug and passed it to the testing team than the testing team checks the other modules of the application means checks that fix a bug does not affect the functionality of the other modules, do not go deep to test the details because of the short time so this is the sanity testing.
What is smoke testing?
Smoke Testing: Smoke testing is another types of functional testing in which developer test the basic functionality of the build. Smoke testing checks whether the software under test is ready for further testing.
How many modules are there in a smoke test?
Example: For Example in a project there are four modules like login, view user, user detail page, and new user creation, etc. So in this four modules first of all developer perform the smoke testing by executing all the major functionality of modules like a user is able to login or not with valid login credentials and after login new user can be created or not, and a user that is created viewed or not. This is the called smoke testing always done by developing team before submitting the build to the testing team.
What is integration testing?
Integration testing is use to check whether different pieces of module working in a proper way. Functional testing is used to check certain functionality of the product or to check the whole system behavior as per the defined requirements. Unit testing is done by developer team.
What is security testing?
Security Testing: Security testing is basically to check whether the application is secure or not. Compatibility Testing: Compatibility testing is basically the testing of the application or the product built with the computing environment.

A functional test case assigns the testing of a function or feature in order to see if it produces the expected result. Every new feature and function must be tested before release, and most need to be continuously tested. For example, you might test a photo upload feature.
What are the different types of testing?
Inexperienced testers might assume that testing features is the only kind of testing that exists, but QA pros know that there are many other types of testing such as performance, usability, and scalability . As a refresher, here’s how functional testing differs from nonfunctional testing.
What are the preconditions for being able to test it?
Preconditions for being able to test it (such as being logged in as a user with a certain access level or paid subscription plan) The steps required to test it. The expected result. When all of this is included, the tester has everything they need to satisfy the requirement of the test case.
Can two testers be assigned to the same case?
For important features and brand new releases, make sure to have some overlap, so that two or more testers are assigned to the same case.
Can you write test cases in test management tool?
Now it’s time to write the test cases inside of your test management tool. This tool should be designed for managing testing and/or development tasks, so that you can input the information needed on the test case, assign it to a tester, and allow them to connect this test case to a bug report if needed.
Do you assign test cases to testers?
There is some strategy required when assigning test cases to testers. You don’t want to do it at random, otherwise, testers will all have to be in different parts of the app instead of dividing and conquering.
