Must-Know Types of Software Testing

Table of Contents

Software development and product development involve the process of coding, code design, code development, and the most important one, software evaluation. This QA testing process includes module-level and product-level testing and also evaluation of the whole unit. There are different types of software testing. The two main categories are Functional and Non-Functional testing. Other types of testing include manual, automated and system testing.

Software testing is an investigation conducted to provide participants with information about the quality of a software product or service under test. Software testing can also provide an objective and independent view of the software to allow businesses to identify and understand the risks of using the software.

Functional testing:

Software testing tells us what the system does and is used to determine how each software application behaves according to the software requirements specification document. This type of QA test helps to check if the actual output follows the desired result & testers need not have to look at the source code of the application.

Non-functional testing:

It revolves around determining how well a system works under various conditions. It refers to various other forms of software testing & some of the most common testing methods are performance, load, stress, security, and compatibility testing.

Manual Testing:

It is a process in which the software gets tested manually to ensure the quality of the software for which exclusive test cases are written and tested for their pass or failure status. There are many types of manual testing & the most common are smoke testing, unit testing, functional testing, and sanity testing.

Automated testing:

It has governed the testing field as many open sources and paid automation testing tools are used to find the flaws and bugs. The software automated testing process involves the creation of test scripts, the use of these test scripts and the entry of bugs in the software to control the crashes.

System testing:

This type of QA test incorporates several testing methods used to validate all software in terms of software, hardware, and networks. It usually evaluates a fully integrated software product and specializes in end-to-end system specifications.

Enables testing and validation and validates application structure based on business requirements to ensure a fully functional product.

Although there are more than 100+ types of testing software, in this article, some of the most common QA testing types are described in detail and categorized extensively under Functional and non-functional testing methods.

What are the Important Functional Testing types?

There are many functional testing methods such as Unit testing, smoke and sanity testing, black box testing, etc.

Unit testing:

It is a preliminary testing type performed by engineers which focuses on a small software design called a unit. Tests were performed on one scalp or a group of related units to test their effectiveness and functionality. In Unit testing, a sample input is used and observed for the corresponding output view.

Smoke Testing:

It is another test method performed by software testers. This type of test helps to ensure that the software or application under test is ready or stable for further testing. If the software is well constructed and fully functional, the testers accept the build and continue to perform the software testing process.

Sanity testing:

It is an effective testing methodology used to validate new additional tasks and get performed before detailed functional testing gets done. This testing method commences as soon as the build is approved to check whether the code changes introduced are working as expected.

Black box testing:

The black box is a software testing methodology where testers do not need to be able to decrypt or encrypt the software & they are not required to know the coding or internal structure of the software. The main focus of the black box testing method is to ensure operational or functional requirements.

What Are The Key Non-functional Software Testing Types?

There are many non-functional testing methods such as Usability testing, performance testing, stress testing, etc.

Performance testing:

It is a method of non-functional testing and is used to test product readiness under the impact of heavy loads. It is done with conscientious testing procedures to determine software’s responsiveness, reliability, and steadiness under varying user loads. It gets attained by measuring response times, output, and application usage levels under test.

Load testing:

It is a vital type of testing software methodology used to verify the ability of the system to manage the expected number of tasks. It also ensures system/application behaviour under normal and high load conditions.

Stress testing:

This test method executes to validate the behaviour of the system when the load rises above its design expectations.

Usability testing:

Usability testing is a core test that can’t get disregarded as it determines whether a particular software system will be able to meet its purpose. The usability testing quickly determines the strengths and weaknesses of the system and assesses the overall usability of the product.


Enterprises and businesses must participate in the development of their products and any delay caused by either delayed or late evaluation will have a direct impact on the total cost of a project. It also damages the quality of the software.

Therefore, to prevent such effects of delayed testing, enterprises should understand the various software testing method types and take full advantage of the testing opportunity through a next-generation testing service provider. Independent software testing services providers with in-house testing experts caper to deliver effective results.

They have professional QA testers, accelerators, and automation testing frameworks to enable effective testing systems and identify bugs and ensure quality software delivery.
