It is small, full-featured and easy to use. It is a relatively lightweight testing tool, which is very simple to use. JMeter is free of installation. After getting the installation package, it can be directly decompressed and used. JMeter can do interface test and pressure test. If JDK is not installed, see the following step s. Step 1: 1. Download JDK to the official website, address: www. Install JDK. After downloading, double-click install.

Official website address: jmeter. Thread group: each task in the test needs to be processed by thread, and all our subsequent tasks must be created under the thread group. Ramp up period in seconds indicates that all threads are created in this time. The advantage is that it will not load the server too much at the beginning.

Ramp up period in seconds : sets how long it takes for the thread to start all. If the number of threads is and the preparation time is 10, it takes one second to start 20 threads. Loop count: the number of requests sent per thread. If the number of threads is and the number of loops is 10, then each thread sends 10 requests. Set true and the execution limit time of the thread scheduler at the same time to be valid at the specified time, as shown in the figure.

Number of samples: that is, the number of requests mentioned above. If successful, it is equal to the number of concurrent times the number of loops you set. Deviation: changes in server response time, the size of dispersion measurements, or, in other words, the distribution of data. Average: average response time unit:. The default is the average response time of a single request. When transactioncontroller is used, the average response time can also be displayed in the unit of transaction.

Because when evaluating the results of a test, it is not enough to have average response time. If there is a test, a total of requests are responded, of which the minimum response time is 0. Do you think that such a large deviation between the minimum and maximum response times will lead to the unreliability of the average value itself? Throughput: throughput. By default, it indicates the number of requests completed per second the specific unit is shown in the figure below. Configure: set the result properties, that is, which result fields are saved to the file.

Generally, you can save the necessary field information. The more you save, it will affect the IO of the load machine. JMeter parameterization If the input parameter changes frequently, it can be set as a variable to facilitate unified modification and management; if the input parameter requires random or multiple choices, it can form a variable through function generator or reading file.

So there are three ways of parameterization: user-defined variables, function generators, and reading files. If for the whole thread group, add assertion response assertion under the thread group; if only for a request, add assertion response assertion under the request. In order to save this parameter, JMeter association is established. For example, login interface and purchase commodity interface, purchase commodity interface needs login information such as token returned by login interface, JMeter association can save this token information, which is convenient for the use of purchase commodity interface.

JMeter association can be completed in two ways to obtain the value specified in the returned result. They are regular expression extractor and JSON path extractor. If the return value you want to get does not match, you can expand the matching data points on both sides of the regular expression.

The previous character can appear at most once and stop after finding the first match 0 or 1. Once the first character is matched, it will not go down. The specific examples are as follows:. The specific example is shown in the following screenshot. At the same time, the database URL format filled in by JDBC connection configuration and the name of jdbc driver are different for different databases.

The list of JMeter database drivers is as follows:. After submitting soapUI, click raw to see the soapation. If some interfaces do not return the soapation, there is no need to fill in JMeter.

JMeter stress testing under Linux 1. After decompressing the installation package under Linux, you can use it. If JMeter environment variables are not configured, the command to run is as follows:. JMX is the prepared JMeter script, res. The second is mixed scenarios, where there are multiple associated interfaces. The pressure measurement time is generally minutes. If it is a fatigue test, it can be pressed for an hour, a day or a week, depending on the actual situation.

Before pressure measurement, it is necessary to define the function and index of pressure measurement. Fixed interface parameters or random interface parameters?

How many concurrencies are required? What is the TPS target? What is the response time? The server name or IP of the server is generally the specified server.

Pressure measurement settings Number of threads: the number of concurrent, how much can run. Specifically, how many users are accessing at the same time Rate up period in seconds : indicates how many seconds JMeter starts concurrency.

Preparation time: how long does it take to set the number of virtual users. If the number of threads is 20 and the preparation time is 10, it takes 10 seconds to start 20 threads, that is, 2 threads per second. Number of cycles: this setting does not change the number of concurrency, and can extend the concurrency time. Pressure test results view. After running, the aggregation report will display the results of pressure measurement. Samples, average, error and throughput were observed.

Samples: indicates the total number of requests issued Average: average response time. Throughput: referred to as TPS, throughput.

By default, it refers to the number of requests processed per second, that is, the processing capacity of the server. The higher the TPS, the better the processing capacity of the server. If there is an error rate, confirm with the development department to determine whether the error is allowed or within what range the error rate is allowed;.

If the number of requests per second of throughput is greater than the number of concurrent requests, it can be increased slowly;. If the performance of the machine is very good, the throughput is less than the number of concurrency, which means that the number of concurrency can not be increased, but can be slowly reduced to find the best number of concurrency; at the end of the pressure test, log in to the corresponding web server to view the CPU and other performance indicators, and analyze the data;.

Maximum number of concurrent: the maximum number of concurrent and the maximum number of TPS are different probabilities. Generally, the number of concurrent increases continuously. When a value is reached and the request times out on the server, the value can be considered as the maximum number of concurrent.

There is a performance bottleneck in the process of pressure test. Performance considerations include: database, application, middleware tomact, nginx , network and operating system.

Next, start JMeter and go through the Building a Test Plan section of the User Guide to familiarize yourself with JMeter basics (for example, adding and removing elements).. Finally, go through the appropriate section on how to build a specific type of Test Plan.
