This section creates a simple test plan to use these components. The test requirements for the program. 1) test target site is fnng.cnblogs.com and tt-topia.rhcloud.com 2) The test is intended to be the response time of the site when the load reaches the QPS.

What is a bean Shell BeanShell is a scripting language that conforms fully to the Java syntax and has some of its own syntax and methods; BeanShell is a loosely typed scripting language (this is similar to JS); BeanShell is written in Java, a small, free, downloadable, embedded Java source code interpreter, with Object scripting language features, a very compact interpreter jar file size of 175k. BeanShell executes standard Java statements and expressions, plus some script commands and syntax. O
thread group--------------------------------------------------------------------------------A performance test request payload is done based on a thread group. A test plan must have a group of threads. A test plan to add a thread group is very simple. Select the thread group in the test plan right-click Pop-Up drop-down menu (add-->threads---> Thread Group).Each test plan in JMeter needs to include at least one thread group, and of course you can create multiple thread groups in a single plan,

Each test plan in JMeter needs to include at least one thread group, and of course you can create multiple thread groups in a single plan, so what is the sequential execution (serial or parallel) between multiple thread groups? Under the test plan, multiple threads are executed in parallel, meaning that

It is different from a thread group because it is not executed unless it is a module controller or is referenced by a controller. Controller Jmeter has two types of controllers: The sample and logic controller, which are used to drive a test. 4.

HLSL can be learned in 2 hours, but it takes many years to be proficient. I have never used define before.

the format of the JMeter script, so it can be identified and imported by JMeter. After the script was imported into JMeter, I added two listeners (see the result tree) because I add listeners in a different location and their scope is not the same. The previous one can only monitor the request of the Www.126.com page and listen to all HTTP requests on the latter side. Scope of a component Let's discuss the scope of the component.

components. Let's start...Jmeter is a desktop application designed to test the C/S structure of applications, such as web applications or FTP applications. Is one of the most widely used open-source testing tools so far. It is written in pure Java and can be extended through its API. Jmeter works on the client in C/S. It can test the server response time, CPU load, memory usage, and resource usage. Most jmeter test scripts or test plans involve creating a loop, simulating requests to the serv
two types of controllers: Samplers and logic controllers.The sampler instructs JMeter to send a request to a server. For example, if you want JMeter to send an HTTP request, add an HTTP requestor. You can add one or more configuration components to a sampler to customize the request. See the sampler for more information.Logic controllers allow you to customize w

classes. In addition, JMeter is able to perform functional/regression testing of the application by creating a script with assertions to verify that your program returns the results you expect. For maximum flexibility, JMeter allows you to create assertions using regular expressions.Environment preparation(1) JMeter is built in the Java environment, so your machine needs to install the Java environment, I like the Java Group of colleagues to a brief installation package, after installation need
