What we learn in this section: Introduction and principle of controller
Scene meeting point
Controller introduction
Controller is the core component of loadruner and is responsible for a variety of tasks. The most common are scenario design, press deployment, script scheduling, monitoring and data collection
The working principle of Controller
Through the scene design to simulate the real operation of the user and call the script in VuGen, and then generate pressure through the set press. During the operation of the scene, the Controller can collect information about the execution of virtual users, transaction response time, throughput, various server resources, and various application resources and display them in real time for our analysis.
There are two ways to start Controller: You can start from HP LoadRunner—>Applications—>Controller under the start menu
You can also select Tools—>Create Controller Scenario from VuGen
Start directly from the icon on the desktop
Start the completed page:
select Scenario Type: There are two main types of scenarios:
Manual Scenario: Manual scenario, you can check whether to use the percentage mode
Goal-Oriented Scenario: Goal-Oriented Scenario: For example: set tps 100, set the range of virtual users, and finally run according to the set time. If the set goal is not reached, you can choose to stop running or continue running
Here is an example of a manual scenario:
After opening the scene
Recommend a software testing learning exchange group: 785128166, there are shared videos, interview guidance, test materials, mind maps, and videos in the group. They are all dry goods, you can download and watch. Mainly share test foundation, interface test, performance test, automated test, TestOps architecture, Jmeter, LoadRunner, Fiddler, MySql, Linux, resume optimization, interview skills, and actual video data of large-scale test projects. Use every minute and every second of your time to learn to improve yourself, and don't use "no time" to conceal your mental laziness! Try hard while you are young, and give your future self an explanation!
