Add teststep fails

Issue summary

While adding a teststep, MTA seems to freeze, or even shuts down and restarts.

The teststep is of type Create / Change / Retrieve.

The freezing starts either:

  • after selecting the Entity, or
  • after selecting a teststep to fill an Association, or
  • after selecting a teststep as source for "Retrieve by previous teststep".

Possible causes and resolutions

Too many attributes or associations

There are too many attributes or associations in the Entity. Generally, more than 200 is problematic on an S21 resource pack.


The least expensive solution is to create a microflow in the Mendix model that Creates / Changes / Retrieves the object, and call that microflow in MTA.

An alternative is to upgrade the Mendix resource pack. See Mendix docs:
