Consider that an e-commerce web application is being tested. In one of the tests, invalid inputs are provided during the checkout process, subsequently the server fails to query the database properly and crashes, resulting in inconsistent records in the database, the failure stack trace is shown to the user.
Which of the following categories of server response does the above belong to?
Abnormal server error
Exposure
Valid response
None of these
Correct answer
Exposure
Which of the following types of non-functional tests is performed by increasing the number of users suddenly by a very large amount and measuring the performance of the system?
Scalability test
Documentation test
Reliability test
Spike test
Correct answer
Spike test
A company designs a new smart TV remote app for smartphones and asks a few users to adjust the volume and change the channel to see if the buttons are easy to find and use.
Which of the following types of testing does the above scenario represent?
Compatibility Testing
Scalability Testing
Usability Testing
Regression Testing
Correct answer
Usability Testing
Consider a form in a web application. During testing, the test team captures session logs and HTTP request logs generated by actual users filling out the form. The team then extracts these logged input sequences and replay them directly (or with slight modifications) against the application to evaluate system behavior.
Which of the following types of testing does the above scenario represents?
Parameter level bypass testing
Control flow level bypass testing
Value level bypass testing
User-session data based testing
Correct answer
User-session data based testing
A user is logged into a secure dashboard in a web application. To request account closure, the user fills out a confirmation form (entering their password and reason for leaving) and clicks the "Submit Request" button. The browser sends the form data to the server. Which of the following transitions would take place in the Application Transition Graph (ATG) in this scenario?
Form Link Transition
Redirect Transition
Operational Transition
Simple Link Transition
Correct answer
Form Link Transition
