Question

- Why do you think that usual maintenance for a widely used website is conducted at 12am or 2am.. etc. on weekends? (List three reasons)

- If you believe that a test is successful when it reveals an error then when do you think that it is the time to release a software to market? (Explain in one paragraph)

Answer 1

a)

1. while system maintainance minimum number of people are active and minimize the chances of unavailability/non-functionality faced by the client
2. As servers in the area which contain a mirror are not facing heavy trafic it is relatively easy and fast to execute maintainance on the system
3. if unexpected downtime is encountered while maintainance ,there is enough time to rollback changes before traffic increases

b)

Once bug triage is complete and your team has finished fixing the defects, the product is considered “live.”

This means that you have reached the final version of the product, and it is ready for distribution or manufacturing (whichever your product requires). The live product is expected to be very stable, relatively bug-free and ready for customer consumption.

Once you have a live product and you reach the scheduled release date (“live date”), the product launch can begin.

bug identification:

If you identify High-level bugs that must be fixed, you can choose to delay the release date. In the case of low-level/cosmetic bugs, you might choose to address them during a future release.

Example: You have the following bug list:

1. No showstopper bugs
2. No high-level bugs
3. Two medium-level bugs
   • User cannot access the address book without an error message
   • When user imports an address, unreadable characters populate the “country” field
4. 10 low-level/cosmetic bugs

In this scenario, you might decide that unreadable characters populating the country field is an acceptable bug because the user can easily delete them. However, you accept you do not want to alarm the user with an error message upon accessing the address book.
