• 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?
• JDBC sampler - use different cache sizes for connection and statement?
  • How do these really work?
  • Should the connection cache be a ThreadLocal item?
  • Need to add debugging to show when cache items are created and destroyed
• XPath Extractor - add user-declared namespaces
• Rework HTTP GUI to make it easier to use and extend
• JDBC IN/OUT/INOUT parameters
• 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)
  • Add unit tests for SOAP/XML-RPC sampler
  • Change name exposed to use to "SOAP/XML-RPC/REST sampler"
• 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, and alternative to "faban"
  • 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)
  • One possible implementation is
    • Add a simple jmeter test plan, with threadgroup, http sampler, and listener, using property values to control behavior to the bin/system_testfiles directory
    • Add shell scripts, for example jmeter_test_http, which just calls the standard jmeter script, with additional "-J" arguments, for example "-Jiterations=10"
    • Need a way of getting the listener output to the console, need some investigation
      • on Windows one can use CON as the file name; /dev/tty for unix - but output is not formatted nicely
      • Summariser can already output to console - that may be enough
• 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 ?

    • Wiki Markup
      Could we remove the "Write All Data to File" setting from all listeners, and instead make a "Write All Data listener" ? \[The simple data writer?\]

• Listeners:
  • make distinction between open file for read and write.
    • at present the browse button does both, which is confusing (given the heading) <= this has been changed
    • a file that has just been read will then be used for writing if a test is run - is that sensible, or should the file name be cleared after it has been read?
    • Graph Transactions Per Second (TPS) like the graphing of Response Time.
• 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"
  • Could perhaps just extend HTTP Defaults for this?
  • N.B. HTTP (Java) relies on system properties to define proxy items, so it is impossible to have more than one setting.
• 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
  • Prevent adding test elements to inappropriate parts of the tree - e.g. controller and sampler must be under a thread group. Should also prevent drag and drop.
• Extend CSV Data Set to read via JDBC
• Assertion Results (or similar) could be used to attach errors to samples - e.g. if a Post-Processor failed, the error could be shown there instead of in the log. Or just add string array for storing such errors?
• Save Graphics should prompt before overwriting files
• Improve Http{{`Mirror}}`Thread class - done, but not submitted (Alf Hogemark)
  • It should allow blocking reads where appropriate, at least when content-length is known
  • Do not use Reader/Writer classes, which uses JVM default character encoding, causing mirrored content to differ
  • Add unit tests
• HTTP Cookie Manager should not clear static cookies each iteration
• Module Controller GUI
  • should it omit leading path name elements as at present?
  • it would be nice if it could check for ambiguous controller names:
    • report error if ambig. name selected? OR
    • flag ambiguous names in the drop-down list?
• user.properties and system.properties should be read from JMeter launch directory if not found in current directory.
• Java Sampler to invoke arbitrary Java method. Would need:
  • classname, method name, params (and types) , classpath
  • this can be done currently with BeanShell, but it would be simpler to have a dedicated GUI.
• Remote Mode selection: might be useful to be able to specify the remote mode for each listener. This would allow the use of immediate mode for a few listeners and statistical mode for most of traffic.
• Hostname is present in the SampleEvent class - can this be saved in the log files?
  • easy for CSV: pass SampleEvent instead of SampleResult.
  • harder for XML, as the default output depends on the class, so using SampleEvent would change the XML element. This would affect any stylesheets etc. However, using SampleEvent as the class would allow the use of a single element instead of both sample and httpSample (and any other future subclasses)
