"Turn" performance test essay, look at it, just do the joke.

1. Performance testing Many people think that the biggest obstacle is the test script development and test results analysis, resulting in a lot of tests to ignore the importance of test planning and design.

2.LoadRunner is just a tool for performance test execution and analysis, and should be subject to the will of the Test designer to avoid being tested by the tool.

3. Stress test = indicator test to constantly increase the pressure to find the limit of the system.

4. Performance testing during the development phase: While developing one side of the performance test, a iterative process is required. Some core algorithm problems can be found through performance testing in the development phase.

5. Load Generator is also called a pressure generator.

6. url-based script is recommended for use with browser-based recording with HTTPS security protocol. (also included with JavaScript)

7. Create a URL (web_url) Form submission (web_submit_from) Link (web_link) image (Web_image)

8. Performance testing will be mainstream later. 9. Performance test is not to give you an indicator, you follow the indicator record the results so simple.

10. Memory overflow results In response time, TPS exceptions, and database CPU exceptions due to a table check may be a requirement for the stored procedures to be tuned.

11. Number of virtual users, hits per second, number of things per second, response time

12. Performance Analysis: 1) The test process of environmental anomalies, such as cup too high, network instability, system parameters are not correct, such results are invalid without analysis; 2) step pressure, otherwise the server can not receive all the pressure request, resulting in a test failure. 3) performance test direct exposure to the problem: The transaction response time is too long, the system supports the maximum concurrent user is too low, the System Application Server CPU utilization is too high or insufficient memory and so on.

13. Insufficient server memory can cause large disk I/O, leading to high CPU utilization, which could be the root cause of a program internal memory leak rather than a memory bottleneck.

14. Causes the database to stop abnormally: 1) The defect of the program algorithm 2) The database configuration is incorrect, the defect of the algorithm causes the CPU resource to consume excessively, and the database configuration error causes the database system to run abnormally.

15. Database Tuning > Oracle's proprietary service model and shared Services model: The proprietary service connection is a one-to-one connection that responds quickly to user requests. However, due to the user's excessive number of connections, for each user to allocate connection resources, the hardware requirements are relatively large. Shared service mode, where one server responds to multiple user connections. As soon as the user requests are executed, the connection is immediately disconnected, and the allocator assigns the idle server process to the other queued user processes.

16. Decreased Ctr of the system usually indicates that the server is responding slowly.

17.HTTP Status Code 200 normal 202 accepted request, but processing has not completed 400 incorrect request 401 an unauthorized customer attempting to access a password-protected page 402 requires a Pay 403 resource not available, the server understands the customer request but refuses to process Typically caused by a file or directory permission setting on the server 404 does not say 405 request method (Get/post/head/delete/put/trace) to the specified resource does not apply 414URI too long 415 unsupported media Type 500 server internal error, Unable to complete request 501 The server does not support the functionality required by the current request 504 network timeout, indicating that the remote server cannot be answered in time 505 the HTTP version indicated in the request is not supported by the server

18. Test Plan: 1) environment construction pull-through 2) functional test (test case design, functional test Execution) 3) Performance test (test case design, test data presets, test script development recording, test case execution, test result analysis) 4) Report Preparation (Result analysis, test report)

19. Performance Test Type: core business scenario Test/Portfolio Business Scenario Test/Strength test/Big Data volume test

20. Performance Test scope: Key test section/non-Focus test section

21. Performance Test objectives: through performance testing to achieve a comprehensive performance evaluation of the server, as far as possible real-life response to the system, for the adjustment and optimization of the system to provide reference.
