Macro generation
As already mentioned in the Introduction, with this adapter you can generate macros that allow you to automate tests in “transformed to HTML” systems. We are going to explain how to record a series of keyboard actions and then execute them.
We connect to the emulator:
Right-click to access the Recording Macro and the Record tab.
We name the file to be recorded and accept. The recording will start.
When we finish and end the recording, we will access again with the right button to the Recording Macro and to the Finish Recording tab.
The file, once the test recording is finished, is saved to: C:\Users\xxxxx\OneDrive\Documentos\5250 where xxxxx will vary depending on the name of each user. Later we will need to find this file to import it.

Next, we access the TAST tool.
-
Check the new diagram box and go to Domain, Project, Folder, Diagram name and Diagram description, as we always do when we design a new diagram. Then the Canvas or blank canvas appears.
-
Access the toolbar and click on the Assistants box.
-
A drop-down menu with different options will appear. The options to choose are:
-
Import from 5250 to 5250.
-
Import from 5250 to HTML.
-
-
We import from Assistants the file that we have recorded and saved in the C: Drive.
-
In either of the two options provided by the Assistants box, a diagram will be automatically generated, which will reflect step by step, the whole recording process of the different actions performed and in which two adapters will appear, the User Object adapter and the 5250 adapter.
-
Save and validate the diagram.
-
And finally, we will take it to the TAST client to execute it.
