Any organization that makes software is very familiar with software testing. Software testing allows you to identify and address any underlying bugs and performance issues in the software before you officially launch it to the public. It ensures that the software matches the expected requirements and prevents any unforeseen “surprises” that may be discovered during the software launch.

In this article, we will discuss the different software testing types you should learn to ensure a high-quality and completely error-free product. Read on to learn about the various types so you can land software testing jobs at reputable IT firms.

6 Software Testing Types to Learn

1. Functional Testing

Functional software testing checks every function of software and verifies it against a specified set of requirements. It basically involves testing the behavior of software and not its source code. There are various types of functional software testing, including:

● Integration Testing

Involves testing individual parts and modules of the software after they are integrated into a group.

● System Testing

Involves verifying whether the integrated and final software complies with the specifications by executing test cases.

● Unit Testing

Involves testing of individual software parts against a set of requirements.

● Interface Testing

Involves testing the communication between different software systems to ensure that it is accurately conducted.

● Sanity Testing

Involves testing the logical reasoning behind the software’s performance.

● Smoke Testing

Involves carrying out the tests of basic functionalities, such as user access and authorization.

● Beta Testing

Involves getting the product tested by users to identify and report any bugs.

● Regression Testing

Involves testing all the functions of the application with old test cases after a new feature has been deployed.

2. Non-Functional Testing

Non-functional software testing checks the software against various parameters such as speed,  performance, ease of use, and reliability. For instance, it checks how the speed of the software is affected when multiple users are logged in at once. There are various types of non-functional software testing, including:

● Performance Testing

Involves testing the speed and performance of the software under a specified workload.

● Stress Testing

Involves testing the reliability of the software by checking how it performs beyond regular workload.

● Load Testing

Involves testing the behavior of the software under a more than usual workload. For instance, it assesses the behavior of a website when it is under high traffic.

● Compatibility Testing

Involves executing test cases to assess the compatibility of software in various environments. For instance, checking how a mobile application works on different operating systems.

● Volume Testing

Involves testing the performance of the software by loading its database with a huge volume of data.

● Security Testing

Involves executing test cases to assess the security of the system and determines how safe it is against unexpected and sudden internal and external attacks.

● Recovery Testing

Involves testing the software’s ability to recover from slowdowns, failures, and crashes.

● Install Testing

Involves testing the performance of the product after installation to ensure that it works according to the expectations.

● Usability Testing

Involves testing the usability of the product by assessing its operations, inputs, and outputs for the end-user.

● Localization Testing

Involves testing the behavior of the software according to the native settings and environments.

3. White-Box Testing

White box testing is carried out to improve the code. In this type of testing, the tester has access to most of the information about the software. They are supposed to identify any inefficiencies in the code, unnecessary lines of code, and bad coding practices to optimize code and fix any security vulnerabilities.

White-box testing is not about the performance of the software. Instead, it focuses on how to improve the software. It is your way to make the software perfect through thorough inspections. The tester is required to check the code without execution as they can’t get all the information after being executed. This process is also called static testing and is often carried out during the initial stages of software development.

4. Black-Box Testing

Black-box testing involves testing the product with the least information about it at hand. The tester has no clue about the structure, logic, or code of the software. They have basically the same info as the end-user to use for functional testing. Black-box testing can only be carried out once the code is executed.

Therefore, dynamic testing is carried out while executing the code and testing the software during the execution. It is to test how the software will be when it is launched and how it will perform at the end user’s end.

5. Grey-Box Testing

As you can expect, testers in grey-box testing have partial information about the software. It is carried out to find bugs that end users are not aware of. For instance, if an element of a website is supposed to be red, but it is pink because of a bug, the user would not know as they would assume that’s how it is meant to be. So grey-box testing would help the tester identify such bugs.

6. Gorilla Testing

Gorilla testing is carried out to test different modules frequently with random inputs to ensure that they are error-free. Gorilla testing is carried out frequently and manually and is only targeted at selected modules to determine their functionality.
