Jmeter type of performance test

• pipe-clean test

1. Previously run in a test environment
2. Determine the accuracy of the script
3. Single-user run
4. Obtain baseline

 

• Capacity Test

1. The classic type of performance test
2. Maximum throughput / concurrent / response time acquisition system is stable when
3. Try to simulate the real situation, such as adding user think time

• pressure test

1. Get the hang system
2. Unless the system is not responding, the response time than expected, the user can not log in, otherwise to stop
3. Assume that the system is expected to sustain 5,000 people, but when 5005 people hung up, this time we should think how

• Stability Test

1. To find out in the long run when the system problems that may arise
2. The classic example is to find memory leaks
3. The system performance is a problem: the response time becomes long gradually or suddenly unavailable
4. somke test
5. Code is modified, affected script code modifications smoke test

• Isolation Test

1. To reproduce the problem
2. The general strategy is to repeatedly perform a module or script problem in order to find problems
   
   

• Load Model

1. Linear model
2. Throughput Model

• Configuring load

1. Big Bang: load while producing
2. Ramp up: start when a certain load, and then from time to time to add some load until the target load, which is typical mode
3. Ramp-up (with step): generating a load segment. For example, a total of 1000 users load, but we need to observe the system at 250, 500, 700 performance under load, after reaching these loads need to run some time to add a new load
4. Ramp up (with step), ramp down (with step): Similarly with the above, only the last load back to 0
5. Delayed start: delayed start

• Testing Process

1. Tested for capacity for each use case: load policy generally ramp-up or ramp-up with step
2. Example of performance problems with the isolation test
3. Tested for capacity with Example Group
4. Isolation of test cases Group: Load Policy is generally ramp-up or ramp-up with step
5. Pressure test with Example Group
6. Stability testing of Example Group use
