10. Which of the following is not a web front-end performance testing tool
A.WebPageTest B.FireBug C.Monkey D.HTTPWatch
Answer: C monkey is an app automation testing tool that comes with the Android SDK
True or False:
1. In the process of performance testing, it is necessary to lay down data ( )
Answer: yes
2. The number of concurrent users in the test tool is set to 100, which means that 100 requests will be sent to the server per second ( )
Answer: False The number of concurrent users equals the number of requests per second only when the response time is exactly 1 second; otherwise, the number of requests per second may be greater than or less than the number of concurrent users.
3. In LoadRunner, the throughput indicator is the number of transactions per second to measure the responsiveness of the system. ( )
Answer: Wrong in LoadRunner, this indicator measures network throughput in bytes, while in JMeter it measures system responsiveness in transactions per second.
4. In the aggregate report in JMeter, the time of "99%Line" in the result represents the response time of 99% of users ( )
Answer: yes
