To include the thread group, right-click the test plan and include the new thread from the thread group. This means they are values that can be used inside the test and populated when the test runs. Props are similar to vars but it has more exposure to features of Jmeter and supports global scope where the var has limited properties on the global scope to the present thread group.

Hover the mouse on 'Add'. #Phenomenon When executing [JMeter] tests, global variables are often used, but after the previous extractor executes the request, if the returned result is data in json format, a JSON extractor will be added below, and under the json extractor will be added A BeanShell PostProcessor to set global variables, as shown below: [After the above Increase the current number of iterations. a. User defined variables are used to defined specific variables which can store some values which you need in different places. What Are JMeter Variables? If the user has to add some functions to the Jmeter variable, he has to cast the string. Scenario properties are merged into global properties and resulting set comes as input for JMeter, see corresponding .propertiesfile in artifacts. JMeter Variable: apply the assertion on the value of a variable (like ${foo}). In JMeter, when you run the test, all information (include error information) will be written into the log file.

Add a HTTP Request Sampler to your Thread Group 3. As you have to extract variables from a Json response, our guides on JMeter Json Extractor and Json Rest Api Testing should prove of great help in the process. This is by design. Scope: Global - All Threads in Test Plan: Sharing Variables Using Properties: Whenever you need to share the variable among all the threads in the Test Plan, Best way to share it using Properties. Now let's see how we can use variables in JMeter as follows. Apache JMeter uses the concept of local and global variables. Assertions can rarely be applied on both the main result and sub-results. We can also use the concept of Global variables in XQuery. For Example, If you need to perform load test of login scenario with 100 unique users. Variable are used to parametrize a test plan.
