apache-jmeter-5.4 增加一些插件， websocket测试

<h1 align="center"><img src="https://jmeter.apache.org/images/logo.svg" alt="Apache JMeter logo" /></h1> An Open Source Java application designed to measure performance and load test applications. By The Apache Software Foundation [](https://travis-ci.org/apache/jmeter/) [](https://codecov.io/gh/apache/jmeter) [](https://www.apache.org/licenses/LICENSE-2.0.html) [](https://stackoverflow.com/questions/tagged/jmeter) [](https://maven-badges.herokuapp.com/maven-central/org.apache.jmeter/ApacheJMeter) [](https://www.javadoc.io/doc/org.apache.jmeter/ApacheJMeter_core) [](https://twitter.com/intent/tweet?text=Powerful%20load%20testing%20with%20Apache%20JMeter:&url=https://jmeter.apache.org) ## What Is It? Apache JMeter can measure performance and load test static and dynamic web applications. It can be used to simulate a heavy load on a server, group of servers, network or object to test its strength or to analyze overall performance under different load types.  ## Features Complete portability and 100% Java. Multi-threading allows concurrent sampling by many threads and simultaneous sampling of different functions by separate thread groups. ### Protocols Ability to load and performance test many applications/server/protocol types: - Web - HTTP, HTTPS (Java, NodeJS, PHP, ASP.NET,...) - SOAP / REST Webservices - FTP - Database via JDBC - LDAP - Message-oriented Middleware (MOM) via JMS - Mail - SMTP(S), POP3(S) and IMAP(S) - Native commands or shell scripts - TCP - Java Objects ### IDE Fully featured Test IDE that allows fast Test Plan **recording** (from Browsers or native applications), **building** and **debugging**. ### Command Line [Command-line mode (Non GUI / headless mode)](https://jmeter.apache.org/usermanual/get-started.html#non_gui) to load test from any Java compatible OS (Linux, Windows, Mac OSX, ...) ### Reporting A complete and ready to present [dynamic HTML report](https://jmeter.apache.org/usermanual/generating-dashboard.html)  [Live reporting](https://jmeter.apache.org/usermanual/realtime-results.html) into 3rd party databases like InfluxDB or Graphite  ### Correlation Easy correlation through ability to extract data from most popular response formats, [HTML](https://jmeter.apache.org/usermanual/component_reference.html#CSS/JQuery_Extractor), [JSON](https://jmeter.apache.org/usermanual/component_reference.html#JSON_Extractor), [XML](https://jmeter.apache.org/usermanual/component_reference.html#XPath_Extractor) or [any textual format](https://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor) ### Highly Extensible Core - Pluggable Samplers allow unlimited testing capabilities. - **Scriptable Samplers** (JSR223-compatible languages like Groovy). - Several load statistics can be chosen with **pluggable tiers**. - Data analysis and **visualization plugins** allow great extensibility and personalization. - Functions can be used to provide dynamic input to a test or provide data manipulation. - Easy Continuous Integration via 3rd party Open Source libraries for Maven, Gradle and Jenkins. ## The Latest Version Details of the latest version can be found on the [JMeter Apache Project web site](https://jmeter.apache.org/) ## Requirements The following requirements exist for running Apache JMeter: - Java Interpreter: A fully compliant Java 8 Runtime Environment is required for Apache JMeter to execute. A JDK with `keytool` utility is better suited for Recording HTTPS websites. - Optional jars: Some jars are not included with JMeter. If required, these should be downloaded and placed in the lib directory - JDBC - available from the database supplier - JMS - available from the JMS provider - [Bouncy Castle](https://www.bouncycastle.org/) - only needed for SMIME Assertion - Java Compiler (*OPTIONAL*): A Java compiler is not needed since the distribution includes a precompiled Java binary archive. > **Note** that a compiler is required to build plugins for Apache JMeter. ## Installation Instructions > **Note** that spaces in directory names can cause problems. - Release builds Unpack the binary archive into a suitable directory structure. ## Running JMeter 1. Change to the `bin` directory 2. Run the `jmeter` (Un\*x) or `jmeter.bat` (Windows) file. ### Windows For Windows, there are also some other scripts which you can drag-and-drop a JMX file onto: - `jmeter-n.cmd` - runs the file as a non-GUI test - `jmeter-n-r.cmd` - runs the file as a non-GUI remote (client-server) test - `jmeter-t.cmd` - loads the file ready to run it as a GUI test ## Documentation The documentation available as of the date of this release is also included, in HTML format, in the [printable_docs](printable_docs) directory, and it may be browsed starting from the file called [index.html](printable_docs/index.html). ## Reporting a bug/enhancement See [Issue Tracking](https://jmeter.apache.org/issues.html). ## Build instructions ### Release builds Unpack the source archive into a suitable directory structure. Most of the 3rd party library files can be extracted from the binary archive by unpacking it into the same directory structure. Any optional jars (see above) should be placed in `lib/opt` and/or `lib`. Jars in `lib/opt` will be used for building JMeter and running the unit tests, but won't be used at run-time. _This is useful for testing what happens if the optional jars are not downloaded by other JMeter users._ If you are behind a proxy, you can set a few build properties in `~/.gradle/gradle.properties` for Gradle to use the proxy: ```properties systemProp.http.proxyHost=proxy.example.invalid systemProp.http.proxyPort=8080 systemProp.http.proxyUser=your_user_name systemProp.http.proxyPassword=your_password systemProp.https.proxyHost=proxy.example.invalid systemProp.https.proxyPort=8080 systemProp.https.proxyUser=your_user_name systemProp.https.proxyPassword=your_password ``` ### Test builds JMeter is built using Gradle. The following command builds and tests JMeter: ```sh ./gradlew build ``` If the system does not have a GUI display then: ```sh ./gradlew build -Djava.awt.headless=true ``` The output artifacts (jars, reports) are placed in the `build` folder. For instance, binary artifacts can be found under `src/dist/build/distributions`. The following command would compile the application and enable you to run `jmeter` from the `bin` directory. > **Note** that it completely refreshes `lib/` contents, so it would remove custom plugins should you have them installed. ```sh ./gradlew createDist ``` Alternatively, you could get Gradle to start the GUI: ```sh ./gradlew runGui ``` ## Developer Information Building and contributing is explained in details at [building JMeter](https://jmeter.apache
