• JDBC connection pooling - possible enhancements
  • Add option to use a single connection per-thread (e.g. if Pool Max=0)
  • or remove pooling altogether? - does it make sense to share connections between threads, which are supposed to be independent users?
  • use Apache DBCP instead of Excalibur?
• XPath Extractor - add user-declared namespaces
• Rework HTTP GUI to make it easier to use and extend
• JDBC IN/OUT/INOUT parameters
• JDBC NULL input parameters (all but done)
• File->Revert command, to easily reload existing file. This is implemented, but not committed to svn (Alf Hogemark)
• File->Open recent files command, bugzilla 31336
• Add HTTP methods dropdown to "SOAP/XML-RPC sampler", bugzilla 42637
• Remove unnecessary code duplication in "SOAP/XML-RPC sampler", rather use code inherited from HTTPSampler2. This is almost done, not committed to svn (Alf Hogemark)
• Make it possible to send file content for HTTP GET, PUT and DELETE using "HTTP Sampler" and "HTTP Sampler 2", and therefore also "SOAP/XML-RPC sampler"
• Make Axis2 / XFire / CFX Sampler, and possible retire existing "Webservice(SOAP) sampler".
  • A bit unsure about this, not sure what benefit is over "SOAP/XML-RPC Sampler".
  • Will we really be testing Axis / XFire client side peformance here ?
  • Or could we make a nice GUI, so it is easier to test web services ?
• Make command line option available, to easily performance test one url
  • This is meant as a replacement for the "ab" command
  • I think it would broaden the user of JMeter a lot
  • I will look into making a "ab result listener", which presents the same statistics as "ab" initially (Alf Hogemark)
• Restructure HTTP Sampler / Settings GUI. bugzilla 41917. A big job, but is becoming necessary, if we are adding more options to the HTTP Sampler
• Add a "View only errors" setting in viewers.
  • Currently, there is a "Log only errors", but I want to have it as a general setting on each listener
  • This will allow a test plan where you can easily look into samples that fails, and get statistics with or without errors (possibly exceptional cases)
    • a "View Results Tree" is set up to only view errors
    • a Summary listener which views all samples
    • a Summary listener only for successes
    • a Summary listener only for errors
  • I find the "Write All Data to File" setting on each listener confusing, since all listeners share the same possible log output, does it not ?
    • For example, the "Graph listener", it does not write graph files to the file does it ? It writes a CSV or XML file ?
    • Could we remove the "Write All Data to File" setting from all listeners, and instead make a "Write All Data listener" ?
• Add a "Preview" button to "CSV Data Set Config", which would use the file name and parameter specification, and bring up a dialog or something to show an example of the variables available and their values.
  • Useful for easily checking that you have specified the columns and variables correctly
  • Could this limit the number of emails on the jmeter-user list asking how "CSV Data Set" works
• Improve documentation
  • Currently, there are quite a lot of question duplication on jmeter-user mailing list, would be nice to reduce that number
  • Does people really read the documentation ? Judging by posts on jmeter-user mailing list, I sometime have my doubts.
  • Would be excellent to have documented steps for "view frontpage, log in, view a page, log out" scenario for the following frameworks
    • Struts
    • Spring
    • Spring Webflow
    • .net applications
    • others (please suggest)
    • I think that could reduce number of mails to jmeter-user mailing list
    • the above could start out as Wiki pages
    • it would be useful to provide sample JMX files as well
• Additional sample JMX files for the various scenarios that are FAQed
  • Perhaps a giant example showing lots of different scripts?
• Support for uploading multiple files in HTTPSampler / HTTPSampler2. I think it the one main missing functionality in HTTPSampler that browser provide, and JMeter not.
  • this is bugzilla 19128
  • I think this is dependent on bugzilla 41917, mentioned above
• Improve support for testing web service. This overlaps with some of the points above.
• Make a "HTTP Caching Manager", this is bugzilla 28502.
  • It is useful for performance testing
  • Would also be useful for functional testing, to see if pages are "cacheable".
• Make a "HTTP Proxy Manager", where the user can specify what proxy settings to use
  • Then use would not have to edit jmeter.properties file or command line arguments to use a proxy
  • We could get rid of the "HTTP Proxy" settings in the "Webservice(SOAP) sampler"
• Make new, nice?, icons for the GUI elements which currently do not have a unique icon. For example the post and preprocessors.
  • Would make it a lot easier to see what is what in the tree
• Make menu options more context sensitive, so they are only enabled when they make sense
  • There seems to be some context sensitivity currently, but the code seems a bit odd, with explicit methods used by various parts of the code
    

...

• Use Java 1.5 for building, but only require 1.4 for running. Is this easy to do? Can it be done in Eclipse?
• Look into warnings when compiling code, some deprecated code should be replaced
• Currently, Apache Avalon seems to be used for logging. Avalon seems to have stalled, should we move to log4j ?
  • I looked into adding a GUI / dialog for "Help->View log" to easily view the jmeter log file from the application itself.
    • Seems to be some open source tools available for log4j which does that out of the box.
  • Would we gain functionality by moving to log4j ?
  • Alternatively, move to Commons Logging (as used by HttpClient currently)
  • What are the risks with continuing to use Avalon, if Avalon is not maintained anymore ?
• Move development to the "trunk" of the Subversion repository
• Upgrade to httpclient4 ? httpclient4 is still only in Alpha. Should / could we have one sampler class using httpclient3 and one httpclient4 ?
• Remove some code in HTTPSampler, which is there fore workaround for httpclient3.0 bug, which has been fixed in httpclient3.1
