We have a special department (QA & QC) to test projects. We follow the series of below mentioned robust testing for the projects we develop. 1. GUI testing 2. Cross browser testing 3. Black box testing 4. Navigation testing 5. Network testing 6. System testing 7. Unit and integration testing 8. Functional testing 9. Testing on various devices and platforms. Before the project is ready for the above mentioned testing, we parse the code using special software and also manually. Our special programmers leave no stone unturned in screening the codes before executing them for the final version.
