What is a configuration element in sampler?

A configuration element works closely with a Sampler. Although it does not send requests (except for HTTP (S) Test Script Recorder ), it can add to or modify requests. A configuration element is accessible from only inside the tree branch where you place the element.

What is a configuration element?

The ConfigurationElement is an abstract class that is used to represent an XML element in a configuration file (such as Web. config). An element in a configuration file can contain zero, one, or more child elements. Because the ConfigurationElement class is defined as abstract, you cannot create an instance of it.

What are Samplers in JMeter?

Samplers in JMeter allows JMeter to send different types of requests to a server. Samplers are the actual requests, JMeter sends to the web server under test. Each sampler (except Test Action) generates one or more sample results. The sample results have various attributes (success/fail, elapsed time, data size etc.)

What is CSV data set config in JMeter?

The “CSV Data Set Config” enables using CSV files as an external data source, where you can keep unique user data like names, emails and passwords. With the help of this config element, JMeter is able to read the CSV file line by line, and then use split parameters to allocate different values for different threads.

What is preprocessor and postprocessor in JMeter?

Processors are of two types Pre-processor and Post-processor. Pre Processor executes before the sampler execution. Post Processors are used to execute the response data from the server and to save the specific extracted values for later use.

What is thread properties in JMeter?

Thread group is the basic element of the Jmeter Test plan. As said in the name Thread group is a group of threads that are executing the same scenario. This is considered the beginning point of a test plan. Thread group holds other test elements like controllers, samplers, config elements also the listeners.

What is Element in JMeter?

The different components of JMeter are called Elements. Each Element is designed for a specific purpose.

Thread Group

Thread Groups is a collection of Threads. Each thread represents one user using the application under test. Basically, each Thread simulates one real user request to the server.

Samplers

As we know already that JMeter supports testing HTTP, FTP, JDBC and many other protocols.

FTP request

Let’s imagine you want to performance test an FTP server. You can use an FTP request sampler in JMeter to do this task. This controller lets you send an FTP “download file” or “upload file” request to an FTP server.

JDBC request

This sampler lets you execute Database Performance Testing. It sends a JDBC Request (an SQL query) to a database.

BSF Sampler

This sampler allows you to write a sampler using a BSF scripting language.

Access Log Sampler

This sampler allows you to read access logs and generate HTTP requests. The log could be image, Html, CSS…

How to add DNS cache manager in test plan?

Add DNS cache manager in Test Plan and select the option “ Use custom DNS resolver” and provide the Hostname or IP addresses and run the test. It will hit both the IP addresses and not one.

What is DNS Cache Manager?

DNS Cache Manager can be used directly under Test Plan or thread group. DNS Cache element Manager helps in testing the applications for the scenarios such as the services are not interrupted because of instance failure or any other reason. JMeter uses default cache as a JVM DNS cache.

What is CSV data set?

CSV Data Set Config serves the purpose of data source which can supply a large amount of data as per the scenario which you are testing.

What is thread binding?

Thread Bind is used to start a session with LDAP server. User provides a username and password to initiate the session. Providing incorrect password starts the anonymous session, but will fail the same.

What is JMeter configuration element?

JMeter Configuration elements allow users to get access to any variable which is further associated with values in JMeter. They can modify the values of the requests which are originated from the Sampler.

How does single bind/unbind work?

Single bind/Unbind works as a combination of both the operations. It opens up the session to check for the validity of the username and password and then ends the session.

What is the default port number for FTP?

Port Number: It is of the FTP server. The Default Port number used is 21. Remote File: When the file has to be globally declared then the only path for the file on the FTP server has to be provided in this field else it can be left blank as well.

What is a test plan in JMeter?

Test Plan: Test Plan is a Parent element under which the other JMeter elements are added. It is a default element. You can rename the test plan as per your project name or test case name.

What is JMeter in Apache?

JMeter is an easy-to-operate tool with a simple UI. Basically, it is an element based tool which has separate elements for all the script building operations like think time, response check, request, cache, test scenario etc. As per your need, you can add JMeter elements and perform the test. Because of its element-based feature, many external plug-ins are available which help to make scripting and analysis part easy. So, let’s try to understand what are all the elements of Apache JMeter.

What is a listener in a sampler?

Listener: A listener is a component that shows the results of the samples. Listener allows you to view and analyze the Sampler request and response in the form of tables, graphs, trees etc. You can also save results in a file and read saved results later.

Can you add JMeter to test plan?

As per your need, you can add JMeter elements and perform the test. Because of its element-based feature, many external plug-ins are available which help to make scripting and analysis part easy. So, let’s try to understand what are all the elements of Apache JMeter. When you launch JMeter in GUI mode, you can see a default element i.e. Test Plan.

Can a config element be global?

Config element can be global or local. Pre-processors: A pre-processor element runs just before a sampler executes.

Is JMeter a child or parent?

Mostly, JMeter elements are scope specific and hence you need to add them in the script logically. Some of the elements can be a parent as well as child element for others, but some element do not follow the hierarchy like ‘Timer’ does not have any child element.

Is a listener a global or local element?

The listener can be global or local. Non-Test Elements: These elements do not directly participate in the test execution, but have a significant contribution to JMeter scripting. HTTP (S) Test Script Recorder specially used to record the test script.

What is configuration element in JMeter?

> Configuration Elements in JMeter are used to configure or modify the sampler requests made to the server. These elements are added at the same or higher level of the samplers they want to configure.

What is assertion in a sampler?

> Assertions are used to validate the sampler response received from the server. In order to test a sampler response, we add different assertions to the sampler. If an assertion fails, the sampler response is marked as failure and the same gets reflected in the test results.

What is logic controller?

> Logic Controllers let you customize the logic that JMeter uses to decide when to send requests. Logic Controllers can change the order of requests coming from their child elements. They can modify the requests themselves, cause JMeter to repeat requests, etc.

What does a pre-processor do?

> A Pre-Processor executes some action prior to a Sampler Request being made. If a Pre-Processor is attached to a Sampler element, then it will execute just prior to that sampler element running.

What is response assertion?

Response Assertion#N#The response assertion used in test scripts to validate a pattern in the response body, header, code, message etc. There are different pattern matching rules to validate the response like-

What happens if JMeter cannot find the text?

JMeter will then check that the text is present in the HTTP response. If JMeter cannot find the text, then it will mark this as a failed request. Note that assertions apply to all samplers which are in their scope . To restrict an assertion to a single sampler, add the assertion as a child of the sampler.

What is a thread group?

Thread group elements are the beginning points of any test plan. All controllers and samplers must be under a thread group. Other elements, e.g. Listeners, may be placed directly under the test plan, in which case they will apply to all the thread groups. As the name implies, the thread group element controls the number ...

What is a listener in JMeter?

Listeners provide access to the information JMeter gathers about the test cases while JMeter runs. The Graph Results listener plots the response times on a graph. The "View Results Tree" Listener shows details of sampler requests and responses, and can display basic HTML and XML representations of the response. Other listeners provide summary or aggregation information.

How to control a thread group?

The controls for a thread group allow you to: Set the number of threads. Set the ramp-up period. Set the number of times to execute the test. Each thread will execute the test plan in its entirety and completely independently of other test threads.

What is a post processor?

A Post-Processor executes some action after a Sampler Request has been made. If a Post-Processor is attached to a Sampler element, then it will execute just after that sampler element runs. A Post-Processor is most often used to process the response data, often to extract values from it. See the scoping rules for more details on when Post-Processors are executed.

What is a test fragment?

The Test Fragment element is a special type of controller that exists on the Test Plan tree at the same level as the Thread Group element. It is distinguished from a Thread Group in that it is not executed unless it is referenced by either a Module Controller or an Include_Controller .
