Apache JMeter

Apache JMeter is an 100% pure Java application used to test performance both on static and dynamic resources like files,  FTP Servers, Servlets, Perl scripts, Java Objects, Data Bases, Queries and more.

JMeter simulates a server/network heavy load, so developers can analyze and interpret how their app behaves in extreme environments.

All results can then be racked up and modeled into a nice graph that can be easily interpreted.

Features:

• Portable
• 100 pure Java
• Extendable
• Multi-threading support
• Concurrent sampling by many threads
• Simultaneous sampling of different functions
• Caching
• Offline analysis
• Replay test results
• Supported server types:
• HTTP & HTTPS
• FTP
• TCP
• LDAP
• JMS
• SOAP
• Mail (POP3, SMTP, IMAP)
• Databases via JDBC
• MongoDB

What is new in this release:

• This release brings improvements to the HTTP(S) Test Script Recorder in the certificate management, some new features and fixes some bugs.

What is new in version 2.7:

• This release brings some valuable improvements and fixes some bugs.

What is new in version 2.6:

• A new toolbar on JMeter's main window.
• A new menu option and button allow to start a test ignoring the Pause Timers.
• Allow System or CrossPlatform LAF to be set from options menu.
• Add "duplicate node" in context menu.

What is new in version 2.5.1:

• This release corrects mainly a few bugs that were introduced in 2.5. Version 2.5 introduced a concurrent download feature for embedded HTML resources. Unfortunately this may result in corrupted downloads or other errors (bugs 51918[1] and 51919[2]). Apache will fix these bugs as soon as possible; meanwhile the feature should not be used.

What is new in version 2.5:

• The HTTP implementation can now be selected at run-time, and JMeter now also supports Apache HttpComponents HttpClient 4.x. Note that Commons HttpClient 3.1 is no longer actively developed, and support may be removed from JMeter in a future release.
• The HTTP sampler now allows concurrent downloads of embedded resources in an HTML page
• The HTTP Sampler can now report the size of a request before decompression.
• The JMS and Mail samplers have been improved.
• The new Test Fragment Test Element makes using Include Controllers easier
• There are various improvements to the View Results Tree Listener
• Bug 30563 - Thread Group should have a start next loop option on Sample Error
• There are two new Thread Group types - setUp and tearDown - which are run before and after the main Thread groups.

What is new in version 2.4:

• JMeter now requires at least Java 1.5.
• HTTP Proxy can now record HTTPS sessions.
• JUnit sampler now supports JUnit4 annotations.
• Added JSR223 (javax.script) test elements.
• MailReader Sampler can now use any protocol supported by the underlying implementation.
• An SMTP Sampler has been added.
• JMeter now allows users to provide their own Thread Group implementations.
• View Results Tree now supports more display options, including search and Regex Testing.
• StatCalculator performance is much improved; Aggregate Report etc. need far less memory.
• JMS samplers have been extensively reworked, and should no longer lose messages. Correlation processing is improved. JMS Publisher and Subscriber now support both Topics and Queues.
• Many other improvements have been made, please see below and in the manual.

What is new in version 2.3.4:

• Fix problems with remote clients - bug introduced in 2.3.3.
• Bug 47377 - Make ClassFinder more robust and close zipfile resources.
• Fix some errors in generating the documentation (latent bug revealed in 2.3.3 when Velocity was upgraded).
• Fixed bug introduced in 2.3.3: JMeter does not start up if there is no messages.properties file for the default Locale.
• FTP Request Sampler: allow specifying an FTP port, other than the default.

Requirements:

• Java 1.5 or higher
