This blog assumes that you have basic understanding of Coded <\/span><\/a>UI and are familiar with the code generated from a recording on Winforms, WPF or Web applications.<\/span><\/p>\n

\n A lot of times, while running a UI test, our test runs into an unexpected pagestate, say an unexpected error dialog, dismissing which would make our test work, or maybe the server takes too long to respond on occasion and if that\u00a0happens, rather than having the test rerun from the start, all we want is for it to resume when the page is loaded. As part of VS Update 1, we have added API support for Retrying or Skipping a failed UI action and continuing playback of the remaining steps in the test.<\/span>\n<\/p>\n

For the purpose of this blog I am taking the example of a winforms application with an alert window. The steps would be no different if you were trying the same on any other supported technology.<\/span><\/p>\n

\n Here\u2019s the scenario:- I have a simple Aut with a textbox where I can enter the age of a user, in case the value exceed \u201c50\u201d an alert prompt is thrown. I want my automation to enter some value and click on \u201cSubmit Age\u201d button, followed by entering some value in the Name TextBox. Clearly, if the age entered exceeds 50, I won\u2019t be able to proceed with entering my Name in the textbox. For such a case, I want the test to dismiss the alert and retry entering the Name in the textbox.<\/span>\n<\/p>\n

\"\"<\/span><\/a><\/span><\/p>\n

The Coded UI Test generated code would look something like this at present<\/span><\/p>\n

\"\"
<\/span><\/p>\n

\u00a0<\/p>\n

Now I would expect step 3 i.e. entering some text into uINameEditEdit to fail. In order to dismiss the alert box and retry the action, I need to follow these steps:-<\/span><\/p>\n

\u00a0<\/p>\n

    \n
  1. Set a retry count- Playback.PlaybackSettings.MaximumRetryCount, i.e. you can specifiy the number of times you want a failed action to be retried. This is not a mandatory argument, if no value is set, the default value will be 1.<\/li>\n
  2. Add a retry handler for the failed step. This is nothing but the handler function which will get called in case of a failure. You can addremove this handler for any step in the coded UI test method, or even in testclass initialize as a generic handler for all failures.<\/li>\n<\/ol>\n

    \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\"\" <\/span><\/p>\n

    \u00a0\u00a0\u00a0\u00a0\u00a0\u00a03.\u00a0 The handler method signature is as shown below<\/span><\/p>\n

    \u00a0\"\"<\/p>\n

    \u00a0<\/p>\n

    Here PlaybackErrorOptions to RetrySkipDefault- for further details, msdn documentation for these options is present here<\/span><\/a>.<\/span><\/p>\n

    \u00a0<\/p>\n

    \u00a0\u00a0\u00a0 4.\u00a0 Now simply setting the PlaybackErrorOptions to Retry will retry your failed step over and over until either the step passes or the MaximumRetryCount is hit. If you want to do any special handling, like say dismissing an alert, you\u00a0can add the code for the same within the handler.<\/span><\/p>\n

    \u00a0<\/p>\n

    The final code for the above defined scenario looks like this:-<\/span><\/p>\n

    \"\"<\/p>\n

    \u00a0<\/p>\n

    And the Retry handler method code:-<\/span><\/p>\n

    \"\"<\/p>\n

    Couple of points to keep in mind:-<\/span><\/p>\n

      \n
    1. \n

      This is supported only for the following exceptions:-<\/span><\/p>\n<\/li>\n

    2. \n
