Functional testing can touch on various types of testing; in reality, there are only a few types of testing normally conducted in the industry unless you’re in a “special category.” The tools are just an example of what’s out there. They are not my recommended tools. In my Automation and Performance section, I will compare the tools based on my experience.
Types of Software Testing Processes:
- Unit Testing
- Integration Testing ” In the SAP world they will call it as SIT”
- System Testing
- Acceptance Testing
- Security Testing
- Usability Testing
- Compatibility Testing
- Regression Testing
- Smoke Testing
- Exploratory Testing
Unit Testing
- Description: Focuses on individual components or units of code to ensure they work correctly in isolation.
- Tools: JUnit, NUnit, TestNG.
Integration Testing
- Description: Tests the integration or interfaces between components, interactions to different parts of the system such as an operating system, file system, and hardware or interfaces between systems.
- Tools: Citrus, Rational Integration Tester.
System Testing
- Description: A complete test of the entire system before it goes live to check if it meets the specified requirements.
- Tools: Selenium, QTP.
Acceptance Testing
- Description: Also known as User Acceptance Testing (UAT), this tests if the system is acceptable to the user and meets their business needs.
- Tools: Cucumber, Watir.
Security Testing
- Description: Identifies threats and vulnerabilities in the software to ensure data and resources are protected.
- Tools: OWASP ZAP, Fortify.
Usability Testing
- Description: Ensures that the software is user-friendly, intuitive, and accessible to end-users.
- Tools: UserTesting, Lookback.
Compatibility Testing
- Description: Checks if the software is compatible with different browsers, database versions, other software, operating systems, and mobile devices.
- Tools: BrowserStack, CrossBrowserTesting.
Regression Testing
- Description: Ensures that new code changes don’t adversely affect the existing functionality of the software.
- Tools: Selenium, TestComplete.
Smoke Testing
- Description: A preliminary test to check the basic functioning of the software before it goes into deeper testing.
- Tools: Postman (for API), QTP.
Exploratory Testing
- Description: An approach to testing where testers explore the software to identify defects or bugs without predefined test cases.
- Tools: Rapid Reporter, Session Tester.
