Regression testing is a type of maintenance testing. Maintenance testing encompasses all testing activities that are performed to identify and fix defects in an existing software system, and regression testing is a specific aspect of this process.

Key Points Maintenance testing is generally divided into two categories:

Corrective Maintenance Testing: This involves testing to identify and fix defects or issues in the software after it has been deployed.

Adaptive Maintenance Testing: This type of maintenance testing is carried out to adapt the software to changes in the environment, such as changes in hardware, software, or regulatory requirements.

Regression testing falls under both corrective and adaptive maintenance testing. When new code is added or existing code is modified, regression testing is performed to ensure that the changes do not negatively impact the existing functionality. This helps in maintaining the reliability and integrity of the software over time.

  • Mean time between failures is the average time between failures and not the average time something works then fails.
    • Mean time between failure (MTBF) = \(\frac{{total\;uptime}}{{number\;of\;breakdowns}}\)
  • Mean time to repair is the average time taken to repair something.
    • Mean time to repair (MTTR) = \(\frac{{total\;downtime}}{{number\;of\;breakdowns}}\)

Availability = \(\frac{{total\;uptime}}{{\left( {total\;uptime + total\;downtime} \right)}}\)

       = \(\frac{{MTBF}}{{\left( {MTBF + MTTR} \right)}} \times 100\;\;\;\;\;\;\;\;\;\;\backslash \backslash percentage\;\)

                       = \(\frac{{20*24}}{{\left( {20*24 + 20} \right)}} \times 100\)

       = 0.96 × 100 = 96%

Important Point:

In MTBF, we converted 20 days into hours = 20 × 24 hours.

Download Solution PDF

The correct answer is option 3


The total cost of the project = Total development cost + Total maintenance cost


Let p1 be the LOC using L1 and p2 be the LOC using L2.

Total cost of the project using L1 = (p1/1000) x 70,000 + (10 x 1,00,000) = 70p1 + 10,00,000

Total cost of the project using L2 = (p2/1000) x 90,000 + (10 x 40,000) = 90p2 + 4,00,000

Given that p2 = 3xp1

=>70p1 + 10,00,000 = 90p2 + 4,00,000

=>70p1 + 10,00,000 = 270p1 + 4,00,000

=> 200p1 = 6,00,000

=> p1 = 3000

Software Engineering Question 15 Detailed Solution

Download Solution PDF

The correct answer: Acceptance Testing

Alpha and Beta testing are forms of:

Acceptance Testing

Important Points

Alpha Testing is usually done by internal staff before the product is released to external testers. It is a type of acceptance testing that's done in a lab environment and not by the end users. It helps identify all possible issues and problems in the system before it goes for Beta testing. 

Beta Testing is performed by actual users or potential customers in their own environment. It is the second phase of testing in which a sampling of the intended audience tries the product out before it is officially released to the general public. This is the final test before shipping the product. Problems that were not discovered during Alpha testing may be identified here.

These types of tests are done to make sure that the system is working as expected and will be accepted by the end users. They are types of User Acceptance Testing (UAT) and are very important in software development processes.
