How do I parameterize my JMeter test cases?
Parameters can be set at both the Test Plan and Thread Group levels. At the Test Plan level, parameters can be used as constants to minimize changes throughout the test plan when a server or port changes, for example. [N.B. functions are not currently supported at Test Plan level.] Within Thread Groups, the User Parameters Pre-Processor can be used to set different parameters for each simulated user. Note: if only one user (i.e. User_1) is defined, the value will be used for all threads. Functions ARE supported here. See later FAQs for more information. The following example parameterizes the pet category from the Java Pet Store. Thanks to jWebHosting.net for allowing us to run the example on their server. • Start JMeter • Click the Add button to add the following user defined variables to the Test Plan node: • server: www.jboss.jwebhosting.net • port: 80 • protocol: http • Add a Thread Group to the Test Plan setting: • Number of Threads: 2 • Clear the forever checkbox • Loop Count: 1
