HttpUnit is an open source test framework for web applications which can provide browser specific behaviour like sending request to the We are using Spring sts , JDK 8, HttpUnit JUnit Tutorial for Unit Testing. 4. However if you’re a programmer who just got the job to create functional or unit tests, you’ll find HttpUnit a much more enjoyable and programmer-friendly toolkit. HttpUnit allows us to test navigating through our JSPs by clicking links and buttons and filling out forms. In this tutorial, we will explain.

Then simulate clicking a button by asking for one of the form’s buttons and submitting it using the WebConversation instance. There are many excellent books and articles regarding the creation of Test Case specifications. With this code in place, the first test will now pass and we can move to the next task. These tools can capture the way the testers interact with the browser, and play it back in a configurable and sometimes programmable manner.
This could be just a simple code comment, or a complex mechanism where the test reports themselves link to the documents; the important thing is to have the reference in the code, and to keep the traceability. A doPost method was added to handle the form submission, and the logic formerly found in doGet has been refactored into the dispatchToSubscriptionPage method.
5.10 Submitting Form Data
This component is responsible acting on the response contents. You should begin each section by copying the initial directory, which includes an ant build script and some classes that you will need to complete it.
Note that ServletUnit ignores any host and port information. Automated, scheduled Test Runs. In case some important elements on the page don’t have IDs or names, we should just ask the developers to add one, rather than trying to work around it.
The binary package tutoroal all the required third party libraries.
The significant points in the code are: Most web applications require a database, and the Test Case scenarios typically have pre-conditions, or initial system state. You should see the following output. ConfigurableTestCase typically contains the common methods, and initialization code for the test case.
Extract the downloaded file into your favorite directory. This code should fail with a HttpNotFoundExceptionhtpunit we have not yet created the servlet class. So any automated test run should be executed on a cleanly built system, using a fresh database, which may already contain some test data specified in the Test Cases.
Testing Web Applications with HttpUnit (Don’t worry, it’s not boring!)
All of this is shown in Example For a simple application, the whole specification could possibly consist of a simple text file with a list of requirements. Abstract There are many expensive or free tools to create tugorial test scripts for web applications. Specifying the authorization information. To run this code, you will also need the web. Creating the ServletRunner class which represents access to a Servlet application. I this example we will develop a program to access the JSP file from tomcat server running locally.
With the test-first approach taken in this chapter, these pieces of functionality should not be written until the corresponding unit tests are written. Instead, work on tiny pieces uttpunit functionality with each new test. That is, first you are encouraged to write and execute a test for the next piece of functionality to be added, verify that the test fails demonstrating that the functionality is not in placeand then implement the functionality and verify that the tutoriql now passes.
However if you’re a programmer who just got the job to create functional or unit tests, you’ll find HttpUnit a much more enjoyable and programmer-friendly toolkit. Now we know how we can write and execute our tests in the IDE. For tutoiral article, let’s assume that you have a set of things you want to test for your web application, organized into sets of Test Case scenarios. Tuutorial course it should be also possible to log in with a specific user, for example to verify the “Register User” Use Case Struts actions can be unit tested with StrutsUnit, and WebWork 2 actions can be unit tested without tutorual web container for example.
The overall goal is to ensure that the form treats the email address as a required field. While writing unit tests is a popular and fashionable activity, most software developers I know either hate or simply don’t like to do functional testing on other people’s applications. Based on the architectural requirements above, for each project I typically create a base Test Case class, which extends the jUnit TestCase class.
The runner will display the list of recognized test methods, and the result of the execution. Here’s an updated test scenario based on our TC architecture. I think the visual feedback is really important – it gives a nice sense of accomplishment especially when writing Unit Tests for our own code. We will also need the Ant build tool to run the tests and generate reports automatically. Don’t assume a specific execution order for your Test tutoriial, or the test methods within the classes.
Each Test Case would describe a scenario htttpunit can be carried out by a web visitor through a web browser. The user may change titorial bet until the pool is closed.

The NewsletterServlet is nearly at its final form. I use a property file to store the server name, the application context, various login names for each role, and some additional settings. However you need to step back a bit and realize that we’re not building a new production system on top of the target-of-test application – these Java classes are no more than test scripts to validate the output of the web site. Functional Testing for Programmers.
Traceability is very important for our Test Cases.
The initial tasks will use the ServletRunner class, thus bypassing the need for a web browser or servlet engine. I typically have a log. For the development of the Test Case implementations, I prefer to work in Eclipse. It will take you through the incremental development of a simple servlet-based web application using a test-first approach.
This way the QA Engineers manually testing the application can see the same initial state and configured pre-conditions for tugorial tests.
