Software & Software Product Testing Methodologies


What are Testing Methodologies?

Testing methodologies are some of the policies and strategies used by the testers to test any software or application to make sure that it is up to standards. This includes testing the software or application that is according to the specifications, has no side effects other than design parameters and worst-case scenario fails safely.

What is Software Testing Methodologies?

Software or software product testing methodologies are a different set of approaches and the method to make sure that the software application is tested before it is released to the public. Software testing methodologies consist of everything from unit testing of each module, integration testing of the entire software to various forms of testing like performance and security.

Importance of Testing Methodologies

These days software applications are getting more complex and intertwined and with so many different platforms and devices that need to be tested, it is more important now to implement a robust testing methodology to make sure that software applications which are being developed are fully tested according to the specifications requirements and can be operated successfully in all the environments with the required security and usability.

This image below shows the various components of testing methodologies and shows how SpiraTest tool is best suited to help you implement and manage them on your current projects.

With SpiraTest you can manage your project requirements, test cases, bugs, and issues using one integrated environment, with all traceability throughout the software development cycle:

  • Ability to decrease your investment in existing technologies. SpiraTest can be easily integrated with the third-party defect management system and automated test solutions
  • It is a highly intuitive web application that gives you a complete picture of the status of the project and health with the use of a web browser
  • SpiraTest is a complete solution that includes test, release management, tracking of defects, and management of requirements are fully integrated once you install the tool

Functional Testing

Functional testing is the part of testing methodologies. It is broken into four different components: integration testing, unit testing, acceptance testing, and system testing. All these testing phases are executed in order. The description on each of them is given below:

Unit Testing

The unit testing is the part of a testing methodology where you can test modules of the application individually that make up an entire application or system. These tests are usually performed by the software developers who have written code for different modules. Moreover, in a test-driven development methodology the test cases are written much before the module is created as the specification of the application. Each module in the application is tested using a specific unit test fixture which is written in the same programming language as the module.

Integration Testing

The integration is another part of the testing methodology. Here the testing of different modules in the application have been unit tested when they are integrated to perform together specific tasks and activities. This testing is done by combining automated functional tests and manual testing depending on how easy it is to create automated tests for specific components.

System Testing

The third part of the testing methodology is called system testing. It performs the testing of the entire system to check for bugs and errors. This testing is done by interfacing the hardware and software of the whole system and then test the entire application as a whole. This type of testing comes under black-box testing, where the software application is checked for working as expected by the user as well as the edge condition and potential exception.

Acceptance Testing

This is the final phase of software or software product testing in the testing methodology. In this testing, the software developers have to make sure that all the software requirements are fulfilled and the customers have tested software to make sure that it is working as expected and meets all their desired requirements.

Non-Functional Testing

In most of the testing or product inspection methodologies, functional testing involves testing the current application against the mentioned requirements. Functional testing is carried out using functional specifications given by the client or design the use case provided by the development team.

Moreover, non-functional testing involves testing the application against the non-functional requirements, which includes measuring the application against the defined quality standards. For instance, usability, vulnerability, scalability are some of the examples of non-functional testing.

Performance, Stress Testing

There is various type of performance testing in most of the testing methodologies. For instance, performance testing measures how the system works under increased load. The stress testing used to verify whether the system can work at the required response time when subjected to an increased load. Also, stress testing is used to find out the failure point of the system when the test loads exceed more than expected.

Usability Testing

In this testing, developers have to look at the end-user usability of the software. How easily the user can access the software forms the main point of testing. Usability testing looks at the five aspects of testing: efficiency, satisfaction, learnability, errors, and memorability.
