IBMRational Integration Tester formerly known as Green Hat. It is a virtualization tool that works on scripting-free environment and being use for continuous integration in software lifecycle. It is a part of rational test workbench and also used to create functional and performance tests for service-oriented architecture (SOA) messaging and business process integration projects. It is compatible with number of enterprise messaging solutions. Tests are conducted by recording system behavior. Rational Integration Tester offers a cost effective test environments which enables customers to test earlier and frequently throughout the development lifecycle.

The document does not attempt to teach the ECMAScript language but points the reader to suitable resources to read. Third party documents either anticipate that the ECMAScript written will run in another context such as a web page, or explain ECMAScript without any execution context. This document therefore sets out to explains or references how ECMAScript can be used within the context of RIT.

ECMAScript code can run within a web page in the web browser (i.e. on the client). The source code is either contained with in the HTML page, or the HTML page contains a reference to another URL or file where the source code is stored. ECMAScript can also run in other contexts, such as RIT.

ECMAScript is a language standard (defined by a standards document). The forerunners of ECMAScript (including various JavaScript implementations and Microsoft's JScript) were not standardised, and this caused numerous problems for developers writing code to run in a variety of web browsers.

A number of vendors have produced implementations of the ECMAScript language. One such implementation is known as Rhino and this is the implementation used by both the Firefox web browser and by IBM Rational Integration Tester.

ECMAScript is a very powerful dynamically typed language with good support for procedural programming, object orientated programming and functional programming. Much ECMAScript used within RIT will be simple procedural code and the average tester will be able to skip or omit many of the more advanced topics in the books on ECMAScript.

For readers who have previously programmed in any source code language then Mozilla's article a re-introduction to JavaScript is a very good place to start. RIT testers may skip over the Introduction and Overview, and can consider everything from the sub heading Custom Objects onwards as optional reading.

O'Reilly's book JavaScript: The Definitive Guide currently in its 6th edition and is a book which consistently gets good reviews. It is an appropriate choice for those looking for a complete understanding of the language. The book now exceeds 1000 pages and contains much more information than most RIT users will wish for or need. Earlier editions are often cheaply available, and an electronic copy the 2nd edition is available on O'Reilly's Web Programming CD Bookshelf.

Strictly speaking there are no ECMAScript features missing from RIT, but since there is no web page there is no document element, and some functions relevant to the browser context (such as "alert") are not defined.

As an example we will image a hypothetical web service which produces an invoice. Amongst its parameters it takes a timestamp for the transaction. This timestamp is then used to populate a number of fields in the report. At the top of the report the date is given in long hand, whilst next to the item just the time is displayed, and finally the date is given in a short hand format at the end of the report.

Because we invoked the web service we know the timestamp we sent (and this is stored in the tag timestamp in the format MM.dd.yy HH:mm). Before we validate the report we wish to populate three tags (longdate, itemtime and shortdate) with values which can be used for validation when the web service reply is received. Having defined those tags in the tag store we can use an ECMAScript function action with this code to calculate those values.

Here we declare a function format for the code which will be called three times. We declare two ECMAScript variables. Firstly ts is declared local to the function action, and then sdf is local to the format function. The tags longdate, shortdate and itemtime (declared in the tag store) are updated. The calculations are handed off to the SimpleDateFormat class (the documentation for which explains the format strings).

The forerunner of IBM Rational Integration Tester (RIT) was formerly know as GH Tester (prior to the IBM acquisition of Green Hat). Only the later editions of GH Tester supported ECMAScript. GH Tester and RIT also share a legacy scripting language intended for evaluating expressions. Prior to the inclusion of ECMAScript in the product any program code was expected to be created in a Java Custom Function which could be called from legacy script (and can now be called from ECMAScript).

Whilst ECMAScript is more powerful than the RIT Legacy Script language it is slower to start up and shut down an ECMAScript function action than a Legacy Script function action. For this reason it is sometimes preferable to make use of Legacy Script function actions when the code must execute within a loop or within a stub which must itself respond quickly.

Java is a strongly typed compiled language. Custom Functions written in Java must be compiled and packaged in a JAR file and deployed to the RIT project from which the Custom Function is to be used. Details of how this may be done can be found in the document Quick instructions for RIT Custom Function in Eclipse.

ECMAScript is currently used within the Function Action, the Decision Action, the Assert Action and the Stub Guard definition within RIT. It is not available for the validation of fields within message actions.

When an ECMAScript function actions starts up the tags are made available in the tags[] array. Where the tag name is a legal variable name in ECMAScript then the tag is also made available as a global ECMAScript variable. For more information see the document Using ECMAScript with tags in IBM Rational Integration Tester which includes a number of example scripts.

Updates to the ECMAScript variables will immediately be available via the tags[] array during the execution of the ECMAScript and vice versa. At the end of execution values are copied back from the tags[] array to the RIT tag store.

This section of the documentation requires the reader to have an understanding of Java ideally including classes, methods, and static methods. This section can safely be skipped by readers not interested in calling Java from ECMAScript.

RIT itself is written in Java. The Java environment can be accessed from the ECMAScript. This includes all the standard Java class libraries, static methods, and any loaded Java custom functions as well as the built-in functions which ship with RIT.

Code seen within a Function Action in a test should be business logic associated with that test. It is preferable to put utility (and controller) code into libraries. This can be done using Java libraries (see above) or ECMAScript Libraries as detailed in the document How to use an ECMAScript function library in RIT.

IBM Rational Integration Tester (RIT) is an integration testing tool. Since (as a test developer using RIT) you already have both RIT skills and a RIT license a sensible approach to unit testing your ECMAScript code is to create a folder in RIT into which you will place your unit tests. Typically those tests will then be added to a suite so that the unit tests can be re-run as a batch.

Each test should contain just a single Assert action. The last statement of the Assert action should evaluate to true when and only when the test passes. The Assert action has a description field where the intent of the test should be recorded.

If your ECMAScript function library does not make use of standard Java libraries, Java custom functions or RIT built-in functions then it is possible to use FireBug to step through it in a test harness (launched from an HTML page, not from RIT). This is explained in How to use FireBug to debug an ECMAScript function for RIT.

If you need to investigate further to determine precisely what is occurring then the document How to determine the Java type of a tag in RIT details how to add logging containing Java type information.

Users who have a working knowledge of ECMAScript but wish to understand how object orientated code can be written in ECMAScript may wish to read the document an introduction to object orientated JavaScript.

Users who have already mastered ECMAScript and are interested in programming generally may be like the article using functional programming techniques to write elegant JavaScript also from IBM developerWorks.
