Common Testing Frameworks.

Hi,

I'm after feedback and comments on the sort of tools and approaches the wider InterSystems community uses for QA Testing applications written in Cache/Ensemble or IRIS. I am aware of the %UnitTest package, and understand how that works... but:

- Do you use an alternative or framework built around this native Unit Testing tool ?

- What is your experience with %UnitTest if you use it ?

- Is there a tool you would recommend for your UI (I know this is not specifically an InterSystems' related question)

I was hoping for some input on the best way to deploy code to site with the following criteria:

- No source code, only compiled code to be deployed.
- Classes and Routines are part of the application.
- Data and code reside in the same database.
- Deployments might be partial updates (i.e. cannot just send a complete CACHE.DAT).

At present the idea is just to export the .obj, any suggestions?

I am integrating with Front End using ODBC to the Caché tables.

I have a property of type %Library.Time in one of the Caché classes FrontEnd which is in C#, it is not possible in C# to represent only a Time type, it always has a date as well (DateTime type, no Time only in C#), but that is fine, should not be a problem, so for Time the date simply defaults to 1900/01/01.

Now when this is sent to Caché it does not like it and I would like to understand why because this is causing us not to be able to use a Caché property of type TIME ever.

With the recent release of macOS 10.15, Apple has tightened its control mechanism , called Gatekeeper, so that it now requires executables to be notarized. InterSystems products are not currently supported for use on macOS 10.15 and the executables have not been notarized. (As a reminder, InterSystems products are supported on macOS as a development platform only.)

I am reading the following code in ObjectScript:

GitHub repository

And there is a sentence which I am facing difficulties to understand:

kill ^OPNLib.Game.CWLF(..World)

I know that kill removes variables, OPNLib.Game are the package and subpackage, and ..World is a property. However what does CWLF mean?

You could think that it is the class' name, but it is:

I have the following message when I try to import a WSDL to generate a SOAP service:

ERROR #5319: The type of a property of a class series cannot be recurring: SeleneHL7Service.hl71.escapeType:escape

I have found in the documentation:

Hi, we are a veterinary lab and we use both the LAB and FIN systems of Antrim. Now we are looking to expose the data in a SQL/Object compatible way so we were wondering if same / similar things had been done by other community members already? If so, could you please share your approach / experience / gotchas with us and we are all ears. I can be reached at yang.jiao@antechmail.com . Thank you!

Hi All

I this article I detail some strategic issues that a new development UI will need to address - these are the ones that I can think of now - others may come to light during this journey.

See the webinar by Eduard Lebedyuk here from the last Global Summit describing modern web development and Caché

And, as always, if I have missed something please comment....

I used the Activate wizard to create a package for Excel (Activate.Excel). There is a class in there that seems to be what we need to open a file:

Activate.Excel.Workbooks.

There is a method that has an Open() command. I tried using it but getting an invalid pointer error.

The parameters are as follows:

Every developer has made the mistake of accidentally leaving temporary debug code in place when they meant to remove it after debugging is complete. The great thing about writing in ObjectScript is that there is a way to make temporary code be truly temporary and automatically self-destruct! This can also be done in such a way that the code has no change of making it into your source control stream, which can be helpful as well.

APM normally focuses on the activity of the application but gathering information about system usage gives you important background information that helps understand and manage the performance of your application so I am including the IRIS History Monitor in this series.

In this article I will briefly describe how you start the IRIS or Caché History Monitor to build a record of the system level activity to go with the application activity and performance information you gather. I will also give examples of SQL to access the information.

I know &SQL returns only one result but is

&SQL(SELECT ID FROM Cinema.Film ORDER BY ID DESC)

and

&SQL(SELECT TOP 1 ID FROM Cinema.Film ORDER BY ID DESC)

the same in terms of processing required?

Hello,

lets have two abstract %Persistent classes A,B with NoExtent keyword (storing data in separate globals for each subclass).

Class A Extends %Persistent [Abstract, NoExtent]

{

}

Class B Extends %Persistent [Abstract, NoExtent]

{

Property Aref As A;

}

Let B class reference the A class. Since the A class has no extent the reference wont work in subclasses. It wont be even usable in SQL. Is it possible to solve this problem? Whats the recommended way to deal with references/relationships using NoExtent?

getting "The value of the property 'cspHttpServerMethod' is null or undefined, not a Function object" error while executing the csp page. All the server side methods stop working at this time although javascript functions still work but until the point where a server side method is getting called. Any clues why we get such error.

This week I am going to look at CPU, one of the primary hardware food groups :) A customer asked me to advise on the following scenario; Their production servers are approaching end of life and its time for a hardware refresh. They are also thinking of consolidating servers by virtualising and want to right-size capacity either bare-metal or virtualized. Today we will look at CPU, in later posts I will explain the approach for right-sizing other key food groups - memory and IO.

So the questions are:
