MEASUREMENT FOR YOUR WEBSITES BY EMILY H. HALILI PDF. Yeah, spending time to review the e-book Apache JMeter: A Practical. Emily H. Halili JMeter is a powerful desktop performance tool from the Apache This book introduces you to JMeter (version ) and test. [BOOKS] Apache JMeter by Emily H. Halili. Book file PDF easily for everyone and every device. You can download and read online Apache JMeter file PDF.

And at the end of Chapter 2 I quickly sought to learn more. As expected we start the meat of the book by installing and running JMeter. I found the list of samples listed surprisingly large and I could guess most of the purposes from the names, but I had to go away and do some research to find out what the JUnit Request sampler did.

Rather than a weakness, I found that a strength of this book. It piques your interest very quickly and you then go away and research that point of interest rather than getting bogged down in the whole JMeter documentation.

Interesting to know … possibly. And then run it and examine the results.

Apache JMeter. Emily H. Halili. Chapter No. 6 "Functional Testing"

Since no one has written any, why not I write one? It takes a quick look at the need to automate testing and whether automation suits all needs of testing.

It provides a quick look at and evaluation of test automation. Chapter 2: Introduction to JMeter This chapter is an overview of JMeter, as it takes a glance at its young history, the general look-and-feel of its GUI design, requirements, and its features.

Chapter 3: Getting Started This chapter serves as a guide to the first-time user on installing and customizing the system environment as they run JMeter for the first time. The installation process will match the purpose of this book. Hence it will skip the more complex setup of the environment.

A more complex setup guide is available from the home site of JMeter. Chapter 4: The Test Plan This chapter sets out to prepare the reader with the basic knowledge of tools required to successfully create and run tests.

It prepares the reader for the next two chapters. The walkthroughs are facilitated by illustrations, giving a more descriptive guide to both new and seasoned testers.

Little is known of JMeter being used to support this testing approach. As in Chapter 5, the walkthroughs are facilitated by illustrations, giving a more descriptive guide to both new and seasoned testers.

Chapter 7: Advanced Features This chapter briefly describes other resources that can be tested by using JMeter, i. It tells the reader where to go in order to find more information about other elements of JMeter that this book does not have. Although JMeter is known more as a performance testing tool, functional testing elements can be integrated within the Test Plan, which was originally designed to support load testing.

Many other load-testing tools provide little or none of this feature, restricting themselves to performance-testing purposes.

Besides integrating functional-testing elements along with load-testing elements in the Test Plan, you can also create a Test Plan that runs these exclusively. This flexibility is certainly resource-efficient for the testing project.

This chapter assumes that you have successfully gone through Chapter 5, and created a Test Plan for a specific target web server. We will begin the chapter with a quick overview to prepare you with a few expectations about JMeter.

The Test Plan we will create and run at the end of this chapter will incorporate elements that support functional testing, exclusively. Preparing for Functional Testing In this regard, I need to highlight that JMeter does not have a built-in browser, unlike many functional-test tools. It tests on the protocol layer, not the client layer i. JavaScripts, applets, etc. In fact, it may not be able to render large HTML files at all.

This makes it difficult to test the GUI of an application under testing.

With some knowledge of HTML tags, you can test and verify any elements as you would expect them in the browser. Unlike for a load-testing Test Plan, it is unnecessary to select a specific workload time to perform a functional test.

In fact, the application you want to test may even reside locally, with your own machine acting as the "localhost" server for your web application. For this chapter, we will limit ourselves to selected functional aspects of the page that we seek to verify or assert. Using JMeter Components We will create a Test Plan in order to demonstrate how we can configure the Test Plan to include functional testing capabilities.

The modified Test Plan will include these scenarios: 1. Create Account New Visitor creating an Account 2. Log in User User logging in to an Account Following these scenarios, we will simulate various entries and form submission as a request to a page is made, while checking the correct page response to these user entries.

Warning message Sorry, this does not match any existing accounts. Please check your details and try again or open a new account below appears. Page reloads. Login successful message You are logged in as: appears. Selecting Add Assertion will be especially useful as we add specific patterns of the page that we want to evaluate as a later part of this exercise. However, to make the recording neater, we will keep this option unchecked. In addition, since we do not require images in our testing, in the URL Pattern to Exclude section, add these patterns:.

Since this Test Plan will employ multiple HTTP request elements targeting the same server and port, this element will be very useful. The web server name will not be captured for each HTTP Request sampler record, since the Request Default element will retain this information.

As we use this default element, our subsequent recording never needs to append the Server name. This element can either be added to the Test Plan and configured manually as an afterthought, or we can simply use the recorded Browser-derived headers element as included in the recording.

For convenience, we will choose the latter option. Once the Proxy Server records the homepage request, stop the recording. You will find a Header Manager for this page is being captured, as Browser-derived header.

Following is a snapshot of this change. Let the Recording Begin Let u s proceed with the recording following the test cases in the previous table as our guide. As you record each page, select the specific tags or page elements the correctness of which you want to validate and add them to the Patterns to Test section in the Response Assertion element of each sampler.

This may take most of your recording time, since as you record, you need to decide carefully which page element s would be the most effective measure of correctness. There are plenty of developer tools available to help you in this possibly tedious task. You may choose patterns that you would expect to see or otherwise by selecting or deselecting the Not option at Pattern Matching Rules section.

You may want to add a few more Configuration elements in your Test Plan, as in my sample shown in the following snapshot: I have added User Defined Variables, two more Listeners, and a Constant Timer with a constant delay of 2 seconds after the request for each page was completed. The Assertion Results listener is used with the Response Assertion elements, to summarize the success or failure of a page in meeting the validation criteria defined in each Response Assertion. Adding User Defined Variables The User Defined Variables UDV elemen t as shown in the following snapshot is particularly interesting with regards to the test case design we drafted earlier in the table.

It allows you to plug values to variables being used in various locations in the Test Plan. The JMeter Test Plan we have created will implement the exact values assigned to different variables. This feature is particularly useful when the assertion depends on varying values, such as when we want to verify URLs, verifying user names, account no, etc.

The following snapshot may give us a clear idea of how a UDV can be used in an Assertion element. Passed assertions will not show any error in Assertion Results Listener installed within the same scope. As for all Listeners, results as captured by the Listeners can be saved and reproduced at a later time.

Following is a sample explaining what passed Assertions would reveal as the Test is executed. On the other hand, a failed Assertion would show an error message in the same Listener as the following snapshot illustrates.

We can view more information about the sampler that contains the failed Assertion to investigate the origins of a failure. A View Results Tree Listener records the details of requests and logs all errors indicated by the red warning sign and red fonts.

The following figure shows that the page was available and page request was successful, however, the assertion failed.Apache Tomcat 7 Essentials. As a new user, these step-by-step tutorial guides will give you all the practical skills necessary to become competent and efficient. Passed assertions will not show any error in Assertion Results Listener installed within the same scope.

It allows you to plug values to variables being used in various locations in the Test Plan. Take your skills to the next level with advanced tutorials that will give you confidence to master the tool's most powerful features.
