Before jumping to their approach, firstly we need to make a few things clear. No one can become Google in one day or a few months. You need to have the courage to face failures. Further, the effort should be consistent and result-driven.
There are four important testing concepts that are considered by Google.
Rather than releasing the large-scale application, focus on releasing it in chunks. Applications with limited features give space to the audience as well as make the testing more precise.
After the first release is made, collect feedback from the end-users and reiterate them for another chunk of the release.
At QAble we have also bifurcated the resources depending upon their responsibilities. By doing this we get more accurate results, which further boosts our confidence. So, if you are looking to hire testers in India, try our resources and feel the difference.
