.　　Preparation time: The number of virtual users that are set up takes a long time to start all. If the number of threads is 20 and the preparation time is 10, then 10 seconds will be required to start 20 threads. That is, starting 2 threads per second.　　Number of cycles: the number of times each thread sends a request. If the number of threads is 20 and the number of cycles is 100, then each thread sends 100 requests. The total number of requests is 20*100=2000. If "Forever" is checked, then al

exception with no transaction and cannot be inserted into the database.Analysis: What is the reason for this: I used the spring MVC framework, when the MVC configuration file scanned the entire package, (including the package in the service), will naturally use @trancetion as a normal bean, so there is no transaction management.For example, the MVC configuration file uses theWorkaround:The settings for the package scan do not include service: There a

suitebuilder extension point. The main function of the extension point is to build a test class from the class. When nunit is started, it will scan the addins directory, load all the assembly, and scan all the public classes. If nunitaddin is implemented, it will store this type into an array. When the core is initialized, the extension points and built-in extensions are loaded first, and then the previous array is traversed to construct the instance
