some examples are Constant Timer, Constant Throughput Timer. Components presented here provide the functionality to introduce User Think Time in various forms among samplers. Timer : By default, a JMeter thread executes samplers in sequence without pausing.User Defined variables config element allows you define variables which can be used across the Test Plan but where each Thread has its own copy. CSV Dataset Config allows you to provide test data like usernames, passwords of Login scenario from a file. Note that these elements are usually processed at the start of the scope in which they are found, i.e. Config Element : Configuration elements can be used to set up defaults and variables for later use by samplers. DOWNLOAD APACHE JMETER 2.3.4 FREEMain stream protocols are supported, for others you can use Free or Commercial plugins. for example, HTTP sampler allows you simulate an HTTP packet (of GET, POST or any supported methods). It gives components to simulate requests of various protocols such as HTTP, JDBC, FTP, SMTP etc. Sampler : Sampler is the core of the JMeter.js files) so that combined response time can be retrieved. one of the useful examples is Transaction Controller, where you combine all the samplers of Login page (all resources including images. Logic Controller : Allows you define the flow of execution and grouping of the samplers.some examples are Thread Group, setUp Thread Group, and tearDown Thread Group you can also define on Test Plan whether Thread Groups need to run in sequential or parallel in the case of multiple Thread Groups. Threads (Users) : you can define a number of (virtual) users to run, ramp-up time and loop count.Scripts can be saved in the Workbench provided you check the 'Save Workbench' checkbox, otherwise they are no. Along with all the components available in Test Plan, you get HTTP(s) Test Script Recorder in order to record the browser actions. Workbench : Is a temporary place to start scripting.You add components to the Test Plan by Right Click on the Test Pand and navigating to the component you want to add. Test Plan : Starting point for scripting.Apache JMeter segregated all the components into following groups based on their functionality:
