Writing a test harness

I am interested in finding out if any people have written test harnesses
for performance testing and load testing.
If so, how did you go about doing it?
I'd like to comments about writing the harness as a Forte application vs
using a shell script to execute Forte methods on Service Objects.
How do you best simulate many users banging on the Forte Service
objects?
Any help would be greatly appreciated
Thanks,
Roland Adolfsson

Think I have it working with the following changes
payload = new String(buffer, "IBM-500");
// Creates the text message to send
TextMessage msg = session.createTextMessage(payload);
msg.setIntProperty("JMS_IBM_Character_Set", 500);

Getting error while writing JUnit test case for RestFul Services

Oracle Test Harness

Hi,
I've read the article named "Out-of-Container EJB 3.0 Testing with Oracle Entity Test Harness (by Debu Panda)" in http://www.oracle.com/technology/pub/articles/debu_testability_of_ejb.html.
Where is it supposed to be locate the ectest.jar file???
I've just downloaded Oracle Toplink DP4 and OAS 10.1.3 DP4 but I can't find it.
Thanks in advanced.

Hi Bjorn,
I've posted the same question a couple of time (see out-of-container Oracle EJB30 Test - ectest.jar location but nobody seems to know the answer.
Please let me know ([email protected]) if you get to know where is the ectest.jar file located (the same way, I'll tell you if I do).
Thank you very much.

Creating a Test Harness

Hi there ....
I have this problem, basically, my self and a few of my class mates have built this program as part of our module and we now need to have a Test Harness to run and log our Test Cases.
I have all the test cases arranged in .txt files and plan on using the 'Test Harness' to read test cases from these files, feed it to our program and then log the output from our programe (the methods) yet again on another .txt file. We have the feature for logging, in the formatted required.
However, non of us has built a test harness before and it looks like a complex procedure, the problem is we dont know how to approach it.
We can test methods that return a value but we dont know how to use the test harness to test void methods that pass data to components or call other methods.
I would appriciate any form of help.
Cheers

Hi yawmark,
I appologise for including a poor code example ealier on, i had to come up with something quick. I will however, visit the sugeted sites you mentioned, thank you.
I did however, create a simple class that compiles and can be used to set, return, reset and print a few details about a person. I hope that is of better use than my previous example. here it is:
public class SimplePerson {
    int age = 0;
    String firstName = "";
    String lastName = "";
    /** Creates a new instance of SimplePerson */
    public SimplePerson() {
    /** Sets the age of this person */
    private void setAge(int takeAge){
        age = takeAge;
    /** Returns the age of this person */
    private int getAge(){
        return age;
    /** Sets the First Name of this person */
    private void setFirstName(String takeName){
        firstName = takeName;
    /** Returns the First Name of this person */
    private String getFirstName(){
        return firstName;
    /** Sets the Last Name of this person */
    private void setLastName(String takeName){
        firstName = takeName;
    /** Returns the Last Name of this person */
    private String getLastName(){
        return firstName;
    /** Resets the details of this person back to back to
     * the default form.
    private void resetAll(){
        age = 0;
        firstName = "";
        lastName = "";
    /** Prints all the details this person has */
    private void printAll(){
        System.out.println("Age: " +Integer.toString(age)
                + "\n First Name: " + firstName
                + "\n Last Name: " + lastName );
}Cheers mate

Server test Harness

Ive been asked to build a test harness.
A simple start would be this.
This will run on a machine and make multiple connections to a HTTP page and read the response given.
The aim of this is to check the server load before it fails.
Does anybody have any code that would enable this.
Does anybody know if it is more realistic to run a number of threads (to mimic people trying to log on) to make the connections or if the application should just try to make so many connections in the shortest period of time?
Would this approach really define the same mechanism as a lot of people trying to connect to the server at the same time?
Any help always apprechiated!!

I can see that it has Web, FTP, JDBC, and JNDI tests. What I specifically want is a load test on a server.
I dont see that it can do this from reading the user guide.
I will go back and have a closer look.
If you know that it can do this then I must be missing something.
Thank you.

Writing JUnit test app to test a method which uses AppResources

Recently I was given a requirement to write a JUnit class( with main) to test a method in a Processor class which is running in weblogic. But this method in processor class makes use of AppResources like this: AppResources appResources = new AppResources("ApplicationResources"); String ruleFileName = appResources.getResourceString("rule.file.irlfile"); But when I try to run my JUnit test (stand alone app with main class) I am getting "java.util.MissingResourceException: Can't find bundle for base name ApplicationResources" exception. The appResources is null... Any ideas how to work around this problem?

It doesn't sound like the Process class was designed for testability outside of its J2EE server container, probably. So writing a unit test for it, under its current design, may be an exercise in futility. You might want to look into "Cactus" tests (search for JUnit Cactus on the web), to test it in its container. Or, redesign the class for testability, separating its business logic better (that's a lot of work to do though) so that it can be instantiated and exercised independently of its environment.

Question about writing Junit test for SQLj application

Just inherite a SQLj application without unit test. After making few enchancement I plan to add unit test about it to make it more solid. What I plan to do is invoke SQLj translator dynamically to generate java source, then compile and invoke the result class dynamically at Junit test. Does anyone how to call SQLj translator as an API call ??

I guess I might add that the error I am getting is
java.lang.nullPointerException
i've got this now:
     public E top() throws EmptyStackException {
          if (numItems == 0)
               throw new EmptyStackException("Stack is empty");
          return S[numItems--];
     }With the same test, as it would throw an emptystackexception not a full..
But the test still doesn't pass.

Test Harness - connnecting to a JSP - Please help

I have three tiers
JSP page
Servlet
Then database
I have a problem where the code is failing if multiple users log on.
To recreate the problem, I am having to repeatedly press f5 to keep firing in database connections which is not graceful, scientific and probably making its own problems such as socket connection failures.
- i need a program (or help) that stimulates multiple users logging onto the JSP page so I can provide max and min connections.
I basically have tried to build a urlconnection to the JSP Page but that doesnt seem to work. Any ideas how to forward this.
Does anybody know how I can stimulate connecting onto a JSP!!
Any help will be most beneficial.
I have tried JMeter but doesnt seem to be too effective.

I followed through its original plan to test out its own site but it seems slow(really slow) and I cant really work out what the graphs were meant to be showing.
I limited to one thread and only one run and it was seriously taking ages.
Is there a better manual to JMeter as the manual seems a little schetchy especially when describing the results.
How long should it take to perform the tests.
Do you have a simple test plan for testing a JSP Page then that you could send me and I could try it through JMeter.

Testing PLSQL code

Hi guys
I working on project where in Oracle9i database there are 90 table and near about 200 triggers,Procedures and functions.My problem is I have to write test cases for all the triggers,Procedures and functions and give them to the Testerso that they can test it.Can Anybody tell me how to do that
Thanks in Advance
Vikramjit

This is not an Oracle thing, this is a general thing.
Rule 1: don't look at the code!
The testers should be considering whether the delivered application satisfies the requirements. Consequently, you need test cases to test what the developers should have written, not what they actually have written. Depending on how low-level your requirements go, you will need one or more test cases for each requirement.
Let's take an example. The application is an insurance claim system. The user requirement to be tested is "the system must print out cheques".
Okay, so we have a piece of system functionality that takes a claims number and optionally an amount; if the user enters an amount the printed cheque is for that amount, otherwise the cheque is for the full amount of the claim. If the cheque is for a partial amount, the amount due must be reduced according. The printed cheque must not exceed the amount due. The cheque printing routine must be able to handle the maximum allowable claim. Finally, remember to look after the pennies when drawing up your test data.
From that the following test cases suggest themselves.
Test Data
Claim No. 1234 for $850.00:
Claim No. 5678 for $850.00:
Claim No. 8888 for $888.88:
Claim No. 9999 for $99999999999999999999999999999.99:
1) Claim No = 1234, amount=100 => result is printed cheque for $100.00
2) Claim No = 1234, amount=null => result is printed cheque for $750.00
3) Claim No = 1234, amount=null => result is properly handled error, claim already paid
4) Claim No = 1234, amount=100 => result is properly handled error, claim already paid
5) Claim No = 5678, amount=0 => result is properly handled error, invalid amount
6) Claim No = 5678, amount=1000 => result is properly handled error, invalid amount
7) Claim No = 5678, amount=-100 => result is properly handled error, invalid amount
8) Claim No = 5678, amount=null => result is printed cheque for $850.00
9) Claim No = 3456, amount=100 => result is properly handled error, invalid claim no
10) Claim No. 9999, amount=null => result is printed cheque for $99999999999999999999999999999.99
11) Claim No = 8888, amount=444.44 => result is printed cheque for $444.44
12) Claim No = 8888, amount=null => result is printed cheque for $444.44
Notes
You will notice that some of these tests must be performed in a specific order. For instance, if you do test 2) before test 1) the expected results are different. However, it doesn't matter if you run test 10) before test 1). Also you have to be on top of your data: you need to know that there isn't a claim 3456 in order for test 10) to pass.
Once you've got beyond this sort of unit testing you need to think about how this requirement meshes with other requirements: for instance, "Cheques can only be printed by authorised users" and "Cheques can only be printed after a claim has had a pay-out authorised".
And so on. By now you may be thinking "This is like writing a program". If that is what you're thinking give yourself a gold star. Wouldn't it be nice if there was a programming language available that would allow you to write these test scripts and run them automatically? You're in luck. You only have to test the database - stored procedures and triggers - so you can use UTPLSQL. This is an open source test harness written in PL/SQL by saint in human form, Steven Feuerstein. It's fantastic. I advise you to check it out: http://utplsql.sourceforge.net/
Using a test harness like UTPLSQL requires some knowledge of the code, specifically which procedures implement which requirements and the signatures of those public procedures. That's all. Testing triggers is done by inserting/updating/deleting rows into the tables and then querying them. UTPLSQL can help with that too.
Good luck, APC

Unit testing in J2EE environment

Hi All:
We have been trying to use Junit for creating unit test scripts, and have been bit successful in unit testing DAOs and Value objects - but problem is testing of components like EJBs and Servlets or even classes like Actions or Commands. Since these components run under application server environment, I am not sure how to unit test them without either deploying them on the actual server or simulating app server and rest of the system.
I was wondering if people could share their experience in writing unit test scripts especially for J2EE components - like Servlets, JSPs and EJBs. On the similar note, is there any similar tool or API for creating integration test scripts?
Thanks,

Well - we already have couple of other servers but that's for beta, QA and Integration testing. Problem is with the unit testing. In unit testing, some piece of code is tested by itself. And I am not sure how I can unit test some of the classes like Servlets, EJBs, JSPs or even dependent classes like Commands or Actions. For example, consider following Action class from Java Pet Store:
public final class CartHTMLAction extends HTMLActionSupport {
public Event perform(HttpServletRequest request)
throws HTMLActionException {
// Extract attributes we will need
String actionType= (String)request.getParameter("action");
HttpSession session = request.getSession();
// get the shopping cart helper
CartEvent event = null;
if (actionType == null) return null;
if (actionType.equals("purchase")) {
String itemId = request.getParameter("itemId");
event = new CartEvent(CartEvent.ADD_ITEM, itemId);
else if (actionType.equals("remove")) {
String itemId = request.getParameter("itemId");
event = new CartEvent(CartEvent.DELETE_ITEM, itemId);
else if (actionType.equals("update")) {
Map quantities = new HashMap();
Map parameters = request.getParameterMap();
for (Iterator it = parameters.keySet().iterator();
it.hasNext(); ) {
String name = (String) it.next();
String value = ((String[]) parameters.get(name))[0];
final String ITEM_QTY = "itemQuantity_";
if (name.startsWith(ITEM_QTY)) {
String itemID = name.substring(ITEM_QTY.length());
Integer quantity = null;
try {
quantity = new Integer(value);
catch (NumberFormatException nfe) {
quantity = new Integer(0);
quantities.put(itemID, quantity);
event = CartEvent.createUpdateItemEvent(quantities);
return event;
In order to unit test above class from say, JUnit test script class, I will have to pass HttpServletRequest object to its method - I will also have to store corresponding command params and store them in the request object - how will you write unit test script for the above class?

Unit testing and integration testing

hello 2 all,
what is the diff bet unit and integration testing? in sap what is unit teesting consists of and integration testing consists of what?
is this the work of test engineers r whose work is this?
take care
love ur parents

Hi Sameer,
Unit Testing
A unit test is a procedure used to validate that a particular module of source code is working properly from each modification to the next. The procedure is to write test cases for all functions and methods so that whenever a change causes a regression, it can be quickly identified and fixed. Ideally, each test case is
separate from the others; constructs such as mock objects can assist in separating unit tests. This type of testing is mostly done by the developers and not by end-users.
Integration testing
Integration testing can proceed in a number of different ways, which can be broadly characterized as top down or bottom up. In top down integration testing the high level control routines are tested first, possibly with the middle level control structures present only as stubs. Subprogram stubs were presented in Section 2 as incomplete subprograms which are only present to allow the higher level control routines to be tested. Thus a menu driven program may have the major menu options initially only present as stubs, which merely announce that they have been successfully called, in order to allow the high level menu driver to be tested.
Top down testing can proceed in a depth-first or a breadth-first manner. For depth-first integration each module is tested in increasing detail, replacing more and more levels of detail with actual code rather than stubs. Alternatively breadth-first would proceed by refining all the modules at the same level of control
throughout the application. In practice a combination of the two techniques would be used. At the initial stages all the modules might be only partly functional, possibly being implemented only to deal with non-erroneous data. These would be tested in breadth-first manner, but over a period of time each would be
replaced with successive refinements which were closer to the full functionality. This allows depth-first testing of a module to be performed simultaneously with breadth-first testing of all the modules.The other major category of integration testing is bottom up integration testing where an individual module is
tested from a test harness. Once a set of individual modules have been tested they are then combined into a collection of modules, known as builds, which are then tested by a second test harness. This process can continue until the build consists of the entire application.
In practice a combination of top-down and bottom-up testing would be used. In a large software project being developed by a number of sub-teams, or a smaller project where different modules were being built by individuals. The sub-teams or individuals would conduct bottom-up testing of the modules which they were
constructing before releasing them to an integration team which would assemble them together for top-down testing.
I think this will help.
Thanks ,
Saptarshi
