Software testing is the process of evaluating a software application to ensure it function as expected and it is free defects. it involves various activities ,techniques and methods to verify that the software the requirement and quality standard.
Testing technique such as black-box testing, white box testing and grey box testing such as depending on the internal knowledge of system. black-box focus functionality without knowledge. grey-box combine both approaches.
The tester understand the software requirement design appropriate test cases and skilled bug tracking and reporting tools with the tools like selenium, Junit , TestNG and postman the testing framework in added knowledge is an added advantage in modern tech.
There different levels and types of software testing:
1,unit Testing:
Test individual unit of components of software testing
Tools- Pytest (python), j unit, n unit
2,integration testing:
Testing the interaction between integrated units or components
Tools- j unit, postman(for API testing)
3,System testing:
Testing complete and integrated software system and verify the requirement for the software.
Tools-Selenium , Load runner
4,Acceptance testing:
The software meets the requirement and ready to deployment
Tools-FitNesse, Cumcumber
5,Regression testing:
Verify the new code changes haven't negatively affected the functionality.
Tools-Selenium ,Test complete
6,performance testing:
Evaluating the software performance, speed, scalability and reliability
Tools-Apache, Load runner
7,Security testing:
Assessing the security features of the software identity
Tools-OWASP ZAP, burp site
8,user interface (UI) testing:
Testing user interface ensure the user friendly behave aspects
Tools-Selenium, cypress
The rise of Devops and agile methodologies continues testing become integral to continues integration and delivery (CI/CD) pipelines
Conclusion:
software testing is not phase but a mindset that ensure quality and reliability the development process. software system more complex role of testing grow in significance . understand approach importance anyone for essential career development of corporate quality assurance
