Automate (and simplify) your 5250 UI testing

Providing flexible, but highly automated, 5250 green screen user interface (UI) testing, X-Replay helps you to develop higher quality – and intuitive – IBM i applications.

With a simple three-step process, X-Replay records your interactive tests, replays them for you automatically and then displays a dashboard to let you know if the results are as expected.

X-Replay also automatically creates test scripts that you can re-run and modify as required (using WHILE loops and other logic).

By eliminating manual testing, X-Replay ensures you and your development team have a thorough and repeatable process for testing. This let’s you make changes to the user interface (and experience) quickly and confidently.

You can test an entire interface, one or more screens or just certain elements in a screen to ensure the best possible experience for your users.

If you’re looking for database regression testing and managing your test data more effectively, X-Replay integrates easily with another product within the X-Analysis suite, X-Dataset or Code Coverage.

How X-Replay works

  • Record: Select the 5250 screen elements you want to validate – and start recording your test.
  • Replay: You can re-run (and modify) tests from scripts that X-Replay automatically creates.
  • Report: Analyse results through the X-Replay dashboard and find exactly where you may have issues with your code.

Test even the largest, most complex IBM i applications. And ensure your sensitive data is protected along the way.

Fresche has established the industry standard for testing IBM i applications with effective automated data and test management tool to help you test undocumented IBM i applications faster. 

X-Dataset includes data subsetting, masking, aging, integrity checking and regression testing. From a main database, X-Dataset creates subsets for testing that maintain complete referential integrity for faster testing speed and accuracy. 

In the majority of IBM i shops, their applications have either been home grown or modified heavily over the years. Although this does represent many years of diligent development, it can lead to significant risk when we consider that testing is key to successful development and implementation.

To ensure coding errors or bugs don’t exist before applications are ‘pushed’ into production it is imperative that you have the right databases to test and those databases are appropriately-sized.

  • Protect your data: X-Dataset enables you to fully anonymise your data to assist compliance with regulations such as GDPR, SOX and HIPAA. Data formats such as dates, names, order numbers, address details etc. are maintained by anonymised for complete protection of personal data (supports regulatory principles such as right to be informed / right to access / right to erasure / tight to restrict processing / right to data portability / right to object and profiling)
  • Manage your test data: build, refresh and test data automatically whilst running validation for table relationships. You can also archive, purge and subset your data to prepare for testing
  • Testing: verify test completeness and identify elements that have not been tested with code coverage reports. You can also analyse before and after reports in regression testing.

If you combine X-Dataset with X-Replay, you can also test screens, data and business logic for complete end-to-end IBM i application testing – whilst ensuring your sensitive data is protected. 


Make IBM i field resizing projects effortless. Automated field resizing with X-Resize.

Outgrown the current size of fields in your databases? Business growth meaning those fields have to be expanded?

Unfortunately, expanding fields in your IBM i applications can cause problems throughout the application: from programs to logical files; to displays, menus and related data files can all be affected.

Reduce your IBM i application development risk, effort and costs by automating field resizing in your IBM i databases and associated RPG programs.

X-Resize gives you the tools to identify and resolve issues across all the stages of a field resizing project, including the ability to:

  • Accurately define the scope for a field resize project
  • Generate detailed impact analysis for all instances of the resized object, including fields, variables, programs, displays and reports (including aliases)
  • Resolve all exceptions that could affect the success of the project
  • Identify all the required manual program changes, for instance where overlapping fields exist or there are screen size restrictions
  • Understand the effort required to complete a resizing project
  • Automatically resize fields in the project in all affected files and programs.

X-A Open

Gain insight into your Java & PHP code running on IBM i

You may already have X-Analysis running across your IBM i analysing and documenting your RPG and CA 2E (Synon) code, but what about the many other languages that can be used across your IBM i?

And, what about the code that’s running on other platforms that just happens to interact with your IBM i applications?

Or even code that doesn’t interact with the IBM i?

X-A Open automatically analyses languages such as Java and PHP to help you understand the code on your IBM i and on other platforms.

Working in a similar way to X-Analysis, X-A Open creates a cross-reference repository for selected coding languages, including Java and PHP.

All you need is access to the sources, regardless of where the applications are deployed.

Documentation is easily exported in Word, Excel or Visio so you can share it easily with others in your business. The graphical interface makes the understanding of complex relationships across applications easy to understand, which ultimately speeds up development time and makes maintenance and support of large, complex applications much easier.

X-2E Analysis

Unlock your CA 2E design model with complete graphical analysis & documentation

You’ve no doubt spent many years developing (and maintaining) your CA 2E (Synon) applications on your IBM i.

But, is the CA 2E out of reach of everyone within your organisation apart from your CA 2E developers?

With X-2E Analysis you can automatically generate graphical documentation of your CA 2E architecture model, as well as extract business rules and application metrics so you can fully understand your CA 2E applications, including:

  • Interactive documentation as ERD of relational data model from CA 2E Model and hand-coded DDS
  • Impact analysis between action diagrams & hand-coded RPG / Java / COBOL / PHP / C#
  • Where used of internal routines
  • Application metrics calculated at both program & subroutine / procedure levels
  • Screen display documentation (layout / fields / actions etc.)
  • Problem analysis for design issues; screen & program complexity, etc.
  • Business rule analysis & documentation
  • Plug-in to Eclipse or WDSc/RDi/RDp.

X-DB Modernize

Convert DDS to DDL automatically. Creation of constraints, long field names & views included

There are many reasons for modernising and re-engineering your IBM i databases – and each is well documented: from accessing the very latest IBM database features to making data more accessible; and from helping to access new international markets to benefiting from advanced query reporting.

Part of the X-Analysis Code & Database Modernization modules, X-DB Modernize converts your DDS database, copies production data into your new database and doesn’t require recompiling programs.

Prior to starting the conversion process, X-DB Modernize provides a report highlighting any potential issues in advance, including, but not limited to:

  • PF files with non-unique keys
  • Files with zero members
  • No matching parent keys in derived constraints.

By re-engineering your IBM i databases to DDL, you’re effectively opening up DB2 to your business and helps you start the process of making your data available through modern UIs, mobile devices and the Cloud.

Technically, X-DB Modernize features:

  • Contains exported procedures for CRUD records in the table
  • Export of DDL from relational data model (including RPG, COBOL or 2E application)
  • Generates database RPGSQLLE service programs
  • Exports UML Class Diagrams from relational data model
  • Creates Hibernate configuration files and JPA package from generated relational model.

X-2E Modernize

Automatically convert your CA 2E (Synon) & RPG applications to modern languages

Although CA 2E combines a rich design model AND powerful code generation capabilities, many businesses running CA 2E are under pressure to modernise their applications to deliver functionality beyond the capabilities of CA 2E.

Reluctant to lose decades of design and development invested in your CA 2E however?

Fresche’s X-2E Modernize could provide the answer by automatically transforming CA 2E (and RPG) into modern languages such as Java.

By doing so, you can:

  • Take advantage of the many open source technologies on IBM i
  • Integrate your applications with other business systems
  • Explore the benefits of the Cloud
  • Make recruiting new resources easier.

Key features of X-2E Modernize

  • Generates standard, modern, highly portable code: in the back end, Spring-based Java exposing REST web services and in the front end, Angular or React
  • Convert from the CA 2E, not RPG, which in turn requires less code – accelerating re-engineering projects
  • Faster conversions with automation
  • Delivers a modern web UI right out of the box
  • Combine with X-2E Analysis, which creates object repository from CA 2E model.

X-Analysis: X-2E Modernize converts RPG & CA 2E to Java


Convert your RPG and CA 2E applications to modern languages automatically

Stable and robust. Those are the very bedrock of IBM i.

You’ve no doubt invested many years in developing and enhancing your RPG and CA 2E based applications to meet your unique business needs.

But if you’re wanting (or under pressure) to modernise your applications so you can take advantage of web and mobile technologies; connect your existing applications with other business systems; or use open source within your applications, then X-Modernize could be the answer as it automatically re-factors and generates a native web application in a modern language such as Java and PHP.

  • Modern architecture: generates Java or PHP applications
  • Complete conversion to native code: all functionality of your RPG and CA 2E applications are converted, generating code which is easier to maintain. For CA 2E projects, X-Modernize uses the design model to ensure completeness
  • Conversion automation speeds up the process – increasing ROI and reducing errors at the same time
  • Modern, highly responsive web UI out of the box which takes full advantage of the latest front end technologies
  • Combine with other modules in the suite: X-Analysis creates your object repository from sources; X-Modernize converts the code; and X-DB Modernize generates your DDL/SQL/UDB database.
