Microsoft Flow – New Feature! – Test your flows

Today I noticed the Test Flow option in my Microsoft Flow designer next to the Update Flow option

Not having noticed it before time to click it!

I then got the following options to me:

  • I’ll perform the trigger action
  • Using data from the previous run.

Previously I could rerun a flow but now there is some more magic put in place. You will see this when you select the second option

Ok, it is a bit of a shame that I can only retest with the most recent 5 runs and in this screen I have no idea which flow instance I’m rerunning. But if this features gets developed a bit further then this could be quite nice.

Now looking at my Run history there is a new type of flow run. All test runs are marked as Test Succeeded (or Test Failed in some cases)

But still I don’t have a clue what happened to which trigger.  But help is at hand. Have you noticed the Download CSV option in the run history?

When you download this CSV you will get some clue. Not pretty, but again it is at least a start.

  1. Hi Pieter, I just tried that. I thought it would just simulate the steps but it actually runs the steps. I had a flow that upon certain criteria sends a mail, I didn’t think the email would get sent (I thought it would go through the steps and then I could download the csv and look at the various steps). Perhaps my understanding of test is incorrect.


    1. Hi Noel, Test is pretty much the replacement for rerun. It does however still rerun the flow. There isn’t any logic in any of the connectors that would simulate a test in the sense of not really doing anything.
      So test is more a matter of you just fix the flow and you want to retest it with the data of a recently failed flow.
