Types of Testing Conducted by QA Testers
QA testers conduct various tests across the development process. It includes functional testing, non-functional testing, regression testing, and UAT.
- Functional Testing: In this QA testing, testers ensure the software functions are developed as per the requirements. It is mainly done during development and before release. For instance, they test and verify the inputs and outputs feature along with the UI behavior, and the system interactions. For this, the tester creates test cases and integrates them manually or with automation. It is all about how the software can meet the expected results.
- Non-Functional Testing: Beyond functional testing, this type of QA testing expands to the non-functional aspect. It verifies whether the system is secure enough against sudden attacks from any sources. It checks its availability and defines the levels, signing on how much the user can rely on it. After checking the code quality, the tester helps the developer to make teams make any necessary adjustments.
- Regression Testing: Regression Testing is all about re-running existing tests after making changes to the code base. Testers mainly conduct it to ensure that new changes, bug fixes, or updates do not break existing functionality. Such type of testing is mainly done during the development cycle or after code modifications. Through regression testing, the development team can ensure that the software continues to meet quality standards and user expectations.
- User Acceptance Testing (UAT): It is the final stage of software testing where real users verify the software in real-time. For instance, along with the QA tester, the actual users and the business representatives may be involved in this process. This testing helps to find out any new significant defects and ensures its compliance with industry standards. Without UAT, there is still a chance of releasing the software with bugs or a lack of a clearly defined goal.
The Cost of Skipping QA Testing
Without having an effective software QA testing process, it’s common to face increased post-release bugs and higher customer support costs. Without proper testing, it leads to reduced user experience, discontented customer bases, and negative effects on the overall ROI.
Post-release Issues
If you release the software with so many bugs in it, you may have to consider costly fixes after deployment. Without proper QA, the higher chances are you will face downtime, data loss or security breaches. It often requires emergency fixes, rolling back updates and costly patches. Developers may need to spend extra time debugging and patching issues, which affects the overall productivity.
Reputation Damage
