1. Unstable infrastructure and technical issues
Environmental issues - Problems like the server timing out constantly, software build crashing deployments, and similar such problems eat away the test period. Companies also attempt to get away with low-capacity servers and set-ups for make-do. This is really a short-term remedy that does not favor anybody. Really, the standard of testing and lack of precious test time may cost them more. This possibly stems from the fact that the value of a healthy, live-like atmosphere for successful QA is undermined by certain businesses (not all). Test data inaccessible: Production-like data is a must for any testing project. Another blocking element still is not bringing this into the QA environment on time. Through generating and maintaining their own test results, testers may also get around this, but it is time-intensive and may not always be on-point.2. Incorrect estimate
If you have begun with an incorrect estimation, things are expected to fail. A successful test estimation must take into consideration the following: Time for preparatory assignments - We are referring to assignments such as:- Identifying and assembling a regression suite
- Creating data from tests
- Time for test readiness assessment (e.g.: Smoke/Sanity Test), etc.
