Changes

This page details the changes made in the current version only.
Earlier changes are detailed in the History of Previous Changes.

Version 3.0

Summary

New and Noteworthy

Test plan creation and debugging improvements

New Search Feature in View Results Tree to allow searching for text / regexp in Request/Responses/Headers/Cookies/… This will ease correlation and Test plans creation

New JSON Post Processor to better extract data from JSON content using user friendly JSON-PATH syntax

JSON is now a first class citizen in JMeter with the introduction of a new JSONPath post processor. This post processor is very similar to Regular Expression Post Processor but is well suited for JSON code. It is based on Jayway JSON Path library

New validation feature, in one click run a selection of Thread Groups with 1 user, no pause and 1 iteration

JSR223 Test Elements do not require a Cache Compilation Key anymore

Just check Cache compiled script if available checkbox and the elements (Pre-Processor, Post-Processor, Assertions, Listeners, …) will pre-compile the script and cache the compiled code if the underlying language supports it

Nashorn can now be used as Javascript engine providing better performance and easier usage

To enable Nashorn, you need to set in user.properties:

javascript.use_rhino=false

Nashorn can be used with Java 8 in the following elements:

IfController
JSR223 Test elements with javascript language selected
__javaScript function

Jexl3 has been integrated. It provides new scripting features and much better documentation

JEXL3 can now be used thanks to a new function __jexl3. JEXL is a language very similar to JSTL.

Simplified HTTP Request UI

A new "Advanced" tab has been added to HTTP Request to simplify configuration. The file upload feature has been moved into a dedicated tab. This increases the space available for parameters in UI and simplifies the UX.

HTTP Request Defaults improvements

You can now configure Source Address (IP Spoofing like feature) and "Save response as MD5 hash" in Advanced Tab

Reporting improvements

New Reporting Feature generating dynamic Graphs in HTML pages (APDEX, Summary report and Graphs)

A dynamic HTML report can now be generated either at the end of a load test or from a result file whenever you want. See Generating dashboard for more details. This report provides the following metrics:

APDEX (Application Performance Index) table that computes the APDEX based on configurable values for tolerated and satisfied thresholds
A request summary graph showing the Success and failed transaction percentage:
A Statistics table providing in one table a summary of all metrics per transaction including 3 configurable percentiles :
An error table providing a summary of all errors and their proportion in the total requests :
Zoomable chart where you can check/uncheck every transaction to show/hide it for:
- Response times Over Time :
- Bytes throughput Over Time :
- Latencies Over Time :
- Hits per second :
- Response codes per second :
- Transactions per second :
- Response Time vs Request per second :
- Latency vs Request per second :
- Response times percentiles :
- Active Threads Over Time :
- Times vs Threads :
- Response Time Distribution :

GraphiteBackendListener has a new Server Hits metric

Summariser displays a more readable duration

Now duration are display in the format hours:minutes:seconds

Generate Summary Results +      1 in 00:00:01 =    1.7/s Avg:     1 Min:     1 Max:     1 Err:     0 (0.00%) Active: 1 Started: 1 Finished: 0

BackendListener now allows you to define sampler list as a regular expression

You can now use a regular expression to select the samplers you want to filter. Use parameter: useRegexpForSamplersList=true and put a regex in pararameter samplersList

Protocols and Load Testing improvements

Migration to HttpClient 4.5.2 has been started. Although not completely finished, it improves many areas in JMeter

Migration to HttpClient 4.5.2 improves the following fields of JMeter:

Support of recent RFC like HTTP State Management Mechanism RFC-6265 for Cookies, you should use now HC4CookieHandler in HTTP Cookie Manager component and select standard Cookie policy
Server Name Indication (SNI) support for HttpClient4 implementation
Improved and better performing validation mechanism for Stale connections and Keep-Alive management, see properties httpclient4.validate_after_inactivity and httpclient4.time_to_live
Many bug fixes since previous version 4.2.6 used in JMeter 2.13, see HttpClient 4.5.X release notes
Better support of HTTP RFC 2616 / RFC 7230 and fixes to issues with deflate compression management

Parallel Downloads is now realistic and scales much better:

Parsing of CSS imported files (through @import) or embedded resources (background, images, …)
Lazy initialization of SSL context: For 15 Threads 138% more sampling in 5 minutes for HTTP only tests. Gain increases as number of threads increases
Rework of Connection management for Parallel Download: This better simulates current browser behaviour and improves throughput. For 15 Threads 135% extra samples in 5 minutes.
Reuse of Threads used for Parallel downloads through a ThreadPool: This improves throughput and increases JMeter scalability for such tests
Total of 750% more throughput found on test with 15 threads, the more threads you have the more the gain
You can now compute and store just the MD5 of embedded resources instead of storing the entire response, this can be done by setting the property httpsampler.embedded_resources_use_md5=true

Introduction of Sample Timeout feature

This new Sample Timeout Pre-Processor allows you to apply a Timeout on the elements that are in its scope. In the screenshot below the 10 second timeout applies to the Debug Sampler and HTTP Request elements.

JDBC request now uses DBCP2 pool

JDBC Request and JDBC Connection Configuration have been updated to replace old Excalibur Pool by Apache Commons DBCP2 pool. As a consequence properties have been migrated to equivalent when available and UI has been updated. Note that unlike Excalibur, Commons DBCP uses the validation query when creating the pool. So make sure the query is valid. The default query suits many databases, but not all - for example Oracle requires 'SELECT 1 FROM DUAL' or similar.

UX Improvements:

Better display in HiDPI screens

See JMeter with a HiDPI screen on Linux or Windows in Hints and Tips section in user manual

New Icon look and Logo

JMeter has a new Logo created by Felix Schumacher.
Icons have also been refreshed to give a more modern style and make them more meaningful

Lots of fixes of annoying little bugs

Around 40 UI fixes have been made to either fix buggy, confusing behaviour or simplify usage by not allowing incompatible options to be selected

Improved Thread Group UI and related actions (Start, Start No Timers, Validate)

Creating and testing a Test Plan before Load Test has been much simplified by allowing you to only start a selection of Thread Group, start them without applying Timers (thus gaining time) or start them using a new Validation mode. This validation mode allows you to start a Thread Group (without modifying it) with 1 thread, 1 iteration and without applying timers. This validation mode can be customized.

New shortcuts

Add most used elements (Ctrl + 0 … Ctrl + 9), configurable through gui.quick_XXX properties
Shortcuts to expand nodes

Core improvements

Configuration simplification with better defaults

Default values for many properties have been modified to make JMeter configuration optimal Out of the box. Read "Incompatible changes" section for more details.

Apache Groovy bundled with JMeter

Apache Groovy, the well-known JVM scripting language, is now bundled with Apache JMeter in lib folder. This allows you to use it immediately through JSR223 Elements by selecting the Groovy language.

Superflous and old properties removed

Old properties that existed to maintain backward compatibility or to offer some superflous customization have been removed. Read "Incompatible changes" section to see which properties have been removed.

Code and documentation improvements

Migration to Java7 source code and use of its syntactic sugar
Major code cleanups
Full review of documentation and improvement both in content and presentation

Improvements to unit tests

Migration of many tests to JUnit 4
Better management of Headless tests
More Unit Tests

Dependencies refresh

Deprecated Libraries dropped or replaced by up to date ones:

Excalibur replaced by commons-dbcp
htmllexer, htmlparser removed
soap removed
jdom removed

Slf4j can now be used within Plugins and core code

You can now use SLF4J logging wrapper in your custom plugins or org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient subclasses.

Incompatible changes

Since version 3.0, Groovy-2.4.6 is bundled with JMeter (lib folder), ensure you remove old version or referenced versions through properties search_paths or user.classpath
Since version 3.0, jmeter.save.saveservice.assertion_results_failure_message property value is true, meaning CSV file for results will contain an additional column containing assertion result response message, see Bug 58978
Since version 3.0, jmeter.save.saveservice.print_field_names property value is true, meaning CSV file for results will contain field names as first line in CSV, see Bug 58991
Since version 3.0, jmeter.save.saveservice.idle_time property value is true, meaning CSV/XML result files will contain an additional column containing idle time between samplers, see Bug 57182
In RandomTimer class, protected instance timer field has been replaced by getTimer() protected method, this is related to Bug 58100. This may impact 3^rd party plugins.
Since version 3.0, you can use Nashorn Engine (default javascript engine is Rhino) under Java8 for Elements that use Javascript Engine (__javaScript, IfController). If you want to use it, use property javascript.use_rhino=false, see Bug 58406.

Note: in a future version, we will switch to Nashorn by default. Users are encouraged to report any issue related to using Nashorn instead of Rhino.
Since version 3.0, JMS Publisher will reload contents of file if Message source is "From File" and the "Filename" field changes (e.g. if it uses a variable that has changed)
org.apache.jmeter.gui.util.ButtonPanel has been removed, if you use it in your 3^rd party plugin or custom development ensure you update your code. See Bug 58687
Property jmeterthread.startearlier has been removed. See Bug 58726
Property jmeterengine.startlistenerslater has been removed. See Bug 58728
Property jmeterthread.reversePostProcessors has been removed. See Bug 58728
Property jmeter.toolbar.display has been removed, the toolbar is now always displayed. See Bug 59236
Property jmeter.errorscounter.display has been removed, the errors/warnings counter is now always displayed. See Bug 59236
Property xml.parser has been removed, it is not used anymore as org.apache.jmeter.util.JMeterUtils#getXMLParser has been deprecated and is not used either. See Bug 59236
Summariser listener now shows the duration in the format HH:mm:ss (Hour:Minute:Second), it previously showed the duration in seconds. See Bug 58776
org.apache.jmeter.protocol.http.visualizers.RequestViewHTTP.getQueryMap signature has changed, if you use it ensure you update your code. See Bug 58845
JMS Subscriber will consider a sample to be an error if the number of received messages is not equal to expected number of messages. It previously considered a sample OK if at least 1 message was received. See Bug 58980
Since version 3.0, HTTP(S) Test Script recorder defaults to using port 8888 (as configured when using Recording Template). See Bug 59006
Since version 3.0, the parser for embedded resources (replaced since 2.10 by Lagarto based implementation) which relied on the htmlparser library (HtmlParserHTMLParser) has been dropped along with its dependencies.
Since version 3.0, support for reading old Avalon format JTL (result) files has been removed, see Bug 59064
Since version 3.0, the default property value for http.java.sampler.retries has been changed to 0 (no retry by default) to align it with the behaviour of HttpClient4.

Note also that its meaning has changed: before 3.0, http.java.sampler.retries=1 meant No Retry (i.e. total tries = 1), since 3.0 http.java.sampler.retries=1 means 1 retry. (Note: this only applies to the Java HTTP Sampler)

See Bug 59103
Since 3.0, the following deprecated classes have been dropped
- org.apache.jmeter.protocol.http.modifier.UserParameterXMLContentHandler
- org.apache.jmeter.protocol.http.modifier.UserParameterXMLErrorHandler
- org.apache.jmeter.protocol.http.modifier.UserParameterXMLParser
httpsampler.await_termination_timeout has been replaced by httpsampler.parallel_download_thread_keepalive_inseconds which is now the keep alive time for the parallel download threads (in seconds).
JDBC Request has been updated to use commons-dbcp2, since then the behaviour is slightly different, ensure you have a correct "Validation Query" for your database. See Bug 58786
The following jars have been removed:
- excalibur-datasource-2.1.jar (see Bug 59156)
- excalibur-instrument-1.0.jar (see Bug 58786)
- excalibur-pool-api-2.1.jar (see Bug 58786)

Known problems and workarounds

The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified).
The numbers that appear to the left of the green box are the number of active threads / total number of threads, the total number of threads only applies to a locally run test, otherwise it will show 0 (see Bug 55510).
Note that there is a bug in Java on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
```
 [java] WARNING: Couldn't flush user prefs:
 java.util.prefs.BackingStoreException:
 java.lang.IllegalArgumentException: Not supported: indent-number
```
This does not affect JMeter operation. This issue is fixed since Java 7b05.
Note that under some windows systems you may have this WARNING:
```
java.util.prefs.WindowsPreferences 
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(…) returned error code 5.
```
The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore.
With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry. This is a known Java bug, see Bug JDK-8000629. A workaround is to use a Java 7 update 40 runtime which fixes this issue.
You may encounter the following error:
```
java.security.cert.CertificateException: Certificates does not conform to algorithm constraints
```
if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits. This error is related to increased security in Java 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too.
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java jdk.certpath.disabledAlgorithms property. Remove the MD2 value or the constraint on size, depending on your case.
This property is in this file:
```
JAVA_HOME/jre/lib/security/java.security
```
See Bug 56357 for details.
Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers. This is due to a known Java bug, see Bug JDK-8065373 The fix is to use JDK7_u79, JDK8_u45 or later.
View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586. This is due to a known Java bug which fails to parse "px" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later.
JTable selection with keyboard (SHIFT + up/down) is totally unusable with JAVA 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later.

　　详情关注这里！http://jmeter.apache.org/changes.html

　　关于报表配置，这里边是有些坑的，但是一般人看看文档，摸索一下，就很容易找着门道了。

　　要看新报表，要改如下文件：

D:\Program Files\apache-jmeter\bin\saveservice.properties

　　官方文档说，默认的配置就是这样，事实并不是这样。需要将这段配置复制过去。

jmeter.save.saveservice.bytes = true
jmeter.save.saveservice.label = true
jmeter.save.saveservice.latency = true
jmeter.save.saveservice.response_code = true
jmeter.save.saveservice.response_message = true
jmeter.save.saveservice.successful = true
jmeter.save.saveservice.thread_counts = true
jmeter.save.saveservice.thread_name = true
jmeter.save.saveservice.time = true
# the timestamp format must include the time and should include the date.
# For example the default, which is milliseconds since the epoch: 
jmeter.save.saveservice.timestamp_format = ms
# Or the following would also be suitable
jmeter.save.saveservice.timestamp_format = yyyy/MM/dd HH:mm:ss

不然执行就会报错的。
控制台执行命令如下：
jmeter -n -t E:\PPmoney\PPmoneySOA.jmx -l e:test.csv -e -o e:report


　　竟然对中文支持不友好，中文乱码。
