Power Fx function
Complete A–Z reference
Assert
Pass-or-fail check used in tests.
What it does
Pass-or-fail check used in tests.
The job: Every function, signal, and operator entry in the canvas-apps reference.
How to use Assert
Start from the task, not the alphabet. If you are shaping rows for a gallery, reach for Assert alongside the other data functions in its group; if you are saving, navigating, or changing state, use it on an event such as a button OnSelect rather than in a display property. When a formula misbehaves, check for a blank value where you expected text, then confirm the behaviour against the examples in the Power Fx function reference hub.
