What are different types of software testing?

08.16.2017

When it comes to software testing, there are a lot of different testing types that each accomplish different goals. Some types of software testing risk analysis can help a company understand the risks of software implementation before moving forward with use – which can help avoid big problems in the future. Other types of software testing helps to find bugs and ensure the product is fit for public use. If your team is wondering what are different types of software testing , here is a breakdown of the various test types.

Software testers use a variety of different tests to improve software.

Manual Testing

Manual testing is an intensive form of software testing because a tester is actually going through each test by hand. If the app has a new functionality, it’s important to test it manually to ensure that the function is working properly. Manual testing is time-consuming and takes up human resources as opposed to automation testing, which uses tools and scripts. However, this type of test can be helpful to use to improve user-friendliness because you get real feedback from a human, which isn’t the case with automation.

Automation Testing

Automation testing uses tools and scripts, not real humans, to run tests on software. Automation is helpful for performing regression test cases because it saves time by doing automated script testing. It’s a good solution for complex situations that are time-consuming when done manually. It’s also much cheaper and faster to automate your testing process. However, automation testing does not entail human observation and cannot guarantee user-friendliness or a positive customer experience – it is only a test to see if the software is functional.

Integration Tests

Integration tests are tests in which a whole team of components are combined, or integrated, to produce output. It seeks to verify the interfaces between components against a software design. The components can be integrated iteratively or all together at once. This type of testing process works to discover defects in the interfaces and interaction between different components. Eventually all of the components are tested against each other until the whole system works. These are usually best performed with automation testing.

Functional tests

Functional tests are tests used to ensure that a specified functionality required in the system requirements works. This process falls under the category of black-box testing, which examines a functionality without knowing what the internal implementation is or seeing the source code. In other words, the testers know what the software is supposed to do, but not how it does it. It helps to see whether the output is coming out correctly.

Functional tests help to improve the user experience.

Acceptance testing

Acceptance testing is a test normally done by a team to verify whether or not the system meets the customer specified requirements. User or customers perform this type of test process in order to determine whether to accept the application or reject it. It is another type of black box testing and helps to ensure that the software works as the customers expected. In many instances, the terms functional test, acceptance test and customer test are used interchangeably.

Performance Testing

Performance testing is usually performed to determine how an application or sub-system works in regard to responsiveness and stability when faced with a certain workload. Basically, the test works to figure out how fast and how effective a program is and to make sure it is meeting performance requirements and generating results within a certain amount of time. The performance testing will examine load times and make sure the system doesn’t crash when confronted with large quantities of data or users.

Load Testing

Load testing is testing that checks the behavior of the software under a large load of data or a large amount of users. It helps to ensure that a software program won’t fail or crash when it gets overloaded with data or when large numbers of people are using it at once. For example, you might test a website under a range of loads to figure out at what point the system might fail – that way you can set limits on the amount of users or amount of data it can take in.

Stress Testing

Stress testing exists to test how the software behaves under poor conditions. If a system is stressed beyond the normal specifications, you can measure how and when it will fail. Examples of stresses are large numbers that go over storage capacity, complex database queries, or other unexpected project workloads. It will help to gauge whether a system is reliable or if it needs another test to help it manage unexpected situations.

Unit Tests

Unit tests are tests that help to make sure the functionality of a certain section of code is working properly. This type of testing is usually created by a developer team as they write the code to catch errors or flaws as they work. The test doesn’t guarantee that the whole system will work, but they help to address individual issues and to make sure that the different components of the software function independently of each other. That way they can be tested together in integration testing later on.
