I am currently exploring the phenomenon that happens to different fields in a form that are bound to the same underlying table field. For an example I have two text fields (TestText and TestTextAlso) on a form that are both bound to the same underlying TestText column...

Last time I was curious about this topic. What happens in the BeforeUpdate event to two separate controls that are bound to the same column? So rather than wonder what would happen... how about we test for the behavior we would want in this situation... which begs the...

Our next test will be to add an Option Group to the form and test that. Now Access has some weird caveats for option groups. You can have radio buttons, checkboxes, or toggle buttons in an Option Group. Each button or box can be labeled, but can only have a numeric...

Yesterday I added a test for a triple state checkbox which should allow null, and True/False values to be set. I was reminded as I had initially tried to use an Access Yes/No field type that this does not have triple state. It can never be null, so therefore will not...

Now I am going to add a triple state checkbox to the form. I have added a new text field that can be nullable, and bound a new "TestCheckTripleState" checkbox to it. The reason for this is that a "Yes/No" Access field cannot be null. It can only be true or false which...

I'm going to start the next test with something simple. A new type of field. I will add a checkbox to the test form and bind it to a Yes/No field and write a test to check to see if it updates the values as expected. I added the checkbox to the form, added a new...

With the new set of functions that I've refactored last time, I'm going to update the other functions to use them. So let's go back to the first 3 counting tests and use the dictionary creation function to make them more readable. Here they are now:...

This test I refactored yesterday to use the new functions which all the tests are using. '@TestMethod("Count Changes") Private Sub WhenTwoFieldsAreChangedThenReturnTwoEntryListOfChanges() Dim testFormAuditor As FormAuditor, dctInput As New Scripting.Dictionary Set...

Today I will refactor the remaining test from the Count group which is counting returned times the BeforeUpdate was triggered. Here is the test I am working to refactor: '@TestMethod("Count Changes") Private Sub WhenTwoFieldsAreChangedThenReturnTwoEntryListOfChanges()...

It is time to refactor the remaining counting tests. Here they are pre refactor: '@TestMethod("Count Changes") Private Sub WhenTwoFieldsAreChangedThenReturnTwoEntryListOfChanges() Dim testFormAuditor As FormAuditor Dim testCollection As Collection Set testFormAuditor...

Last Test Driven Development session I refactored the last test I did to make it easier to read and understand. I created a couple of helper functions to do this. Functions that would take specified inputs, update the fields, then test to see if the resulting audit...
