3 Essential Types of Software Testing

3 Essential Types of Software Testing

Software testing is a broad field under software engineering that is very necessary in ensuring the delivery of a high-quality software product. If developers just go through the process of software development without fully carrying out testing, the software product is doom for failure and dissatisfaction.

No matter how much of a perfectionist a developer is, we’re all bound to make mistakes and commit errors, whereas every organization has an end goal that comes with its own set of expectations. Testing will help identify errors present in software product as well as help developers notice steps they might have omitted during development process.

Users’ satisfaction and value orientation are the ultimate desire of every developed software product as well as getting good reviews when the software is launched, however, the reverse will be the case, when users are the one who noticed bugs or that the software product is malfunctioning – testing will help guarantee all of these.

There are different types, methods and approaches to testing that developers must be familiar with to ensure proper functioning of software products but what really is software testing?

What is Software Testing?

Software testing is the process of evaluating and verifying that a software product or application does what it is supposed to do. It can also be defined as the process of analyzing a software product to identify defects or errors and to evaluate the features of the software product.

Testing includes examination, analysis, observation, and evaluation of different aspects of the software product before launching the product to the market.

Types of Software Testing

Software testing is generally classified into three main categories, each one has different types under it:

  1. Functional Testing

This involves the testing of the functional aspects of a software product where each and every functionality is tested to see whether one is getting the desired results or not.

Functional testing include the following:

  • Unit testing
  • White box testing
  • Black box testing
  • Interface testing
  • Integration testing
  • End-to-end testing
  • Regression testing
  • Acceptance testing
  • Alpha testing
  • Beta testing
  1. Non-Functional Testing or Performance Testing

Non-functional tests are performed after the functional tests, where the non-functional aspects of the product such as performance, reliability, usability, security, etc., are properly handled. It help improve the quality of the software to a great extent.

Functional testing test to see if the software works or not, whereas non-functional checks how well the software runs, and many other things.

There are several types of non-functional testing, which include the following:

  • Performance testing
  • Security testing
  • Compatibility testing
  • Usability testing
  • Scalability testing
  • Stress testing
  • Maintainability testing
  • Compliance testing
  • Efficiency testing
  1. Maintenance Testing

This is done on an already deployed software product. Performing testing after a software is released is known as maintenance testing.

At times there will be need to correct, enhance or upgrade software during its run time – these modifications need to be tested thoroughly. The testing done during this upgrading or enhancing phase is known as Maintenance Testing. Maintenance testing include:

  • Confirmation Testing
  • Regression Testing

Ways to Carryout Software Testing

There are 3 ways you can do software testing:

Manual testing: this is the most primitive technique of all testing types in which test cases are executed manually by a tester without using any automated tools with the purpose of identifying bugs, issues, and defects in the software product.

Automated testing: this is a testing technique that is done using special automated testing software tools to execute a test case suite with the goal of reducing the number of test cases to be run manually. Automated testing does not completely eliminate Manual Testing.

Continuous testing: this is a testing technique that execute automated tests as part of the software delivery pipeline in order to obtain feedback on the business risks associated with a software release as rapidly as possible. Continuous Testing expects testing to be embedded within the development process, not tacked on at the end while executing the right set of tests at the right stage of the delivery pipeline.

Conclusion

Testing can be extremely challenging, that is why it is extremely important to get a dedicated software tester or team of testers like Podtech, who are properly equip with the necessary knowledge of testing and think as well as act from an End User perspective.
