Answer: The QA/Testing process consist of the following:
1. Requirement specification
2. Reviewing the code.
3. Unit testing
4. Integration test
5. Performance testing
Explanation:
We start of by the requirement specification try to gather all the information accurately. Then begins the coding process where there is review of the code so that they perform their desired purpose. After modules are completed we perform unit testing of the different modules individually and also do the integration testing once all the modules are completed. At the end we perform the performance testing to take a note on their desired output and other quality parameters.
