Full Test Pass

ClayCo — Wed, 21 Apr 2004 00:41:00 GMT

I haven't posted a lot in the last few weeks, and there's a succinct reason for that. In fact, I can name it in three words: Full Test Pass.

The concept is close to what it sounds like. During the earlier stages of product planning, the test team for ASP.NET and the web development profile for Visual Studio used the time to plan its test coverage. In total, we wrote descriptions of over 40,000 test cases that we wanted to run. In the span of about four weeks ending earlier this month, we took the time to acutally execute nearly all of them, many for the first time.

Don't take that to mean that we whittled away all the hours between whiles drinking beverages and playing foosball -- we are professionals, after all. We used the time to automate a large subset of our tests, including our acceptance tests (tests that we run on each daily build of the product to get a rough sense of its quality and catch really the big bugs). Automation infrastructure -- the libraries and components our testcases use to simplify automation and manage the process of reporting results to our testcase management database (named Mad Dog, if you can believe it) -- also took up a lot of time.

But 40,000 is a big number, and in that number were a lot of scenarios that we just hadn't tried yet. For example, one of the features I own is Control Designers, which is the mechanism a custom control developer uses to control the appearance and behavior of her control in Visual Studio's web design environment. As part of this, I test several new host services that are exposed by Visual Studio which the authors of Control Designers can use to simplify their work. One of these is an interface with the name IWebFormsBuilderUIService, which exposes methods for creating common UI dialogs, among them a URL editor. In Visual Basic .NET, the code a control author would need to write in order to use this would be something like this:

Imports System.ComponentModel
Imports System.ComponentModel.Design
Imports System.Web.UI.Design
Imports System.Web.UI
Imports System

<Designer(GetType(ExampleControlDesigner)), . . . > Public Class ExampleControl
    Inherits System.Web.UI.WebControls.WebControl

    Dim _url As String

    <Bindable(True), Category("Appearance"), DefaultValue("")> Property URL() As String
        Get
            Return _url
        End Get

        Set(ByVal Value As String)
            _url = Value
        End Set
    End Property

    . . .
End Class

Public Class ExampleControlDesigner
    Inherits ControlDesigner

    Protected Overrides Sub OnClick(ByVal e As DesignerRegionEventArgs)
        Dim iwfbuis as IWebFormsBuilderUIService
        Dim ctl As ExampleControl

        Mybase.OnClick(e)
        ctl = Component
        iwfbuis = GetService(GetType(IWebFormsBuilderUIService))
        try
            ctl.URL = iwfbuis.BuildUrl(Nothing, ctl.URL, RootDesigner.DocumentUrl, "Please Choose a URL", "", UrlBuilderOptions.None)
        catch ex as exception
            Msgbox(ex.Message)
        end try
        UpdateDesignTimeHtml()
    End Sub

    . . .
End Class

The above code would bring up Visual Studio's URL dialog when the user clicked on the control, and set the control's URL property to the user's selection.

I don't have any acceptance-level tests for IWebFormsBuilderUIService.BuildUrl, because even if this method were completely busted beyond usability, it wouldn't especially hurt the other testers on our team or the other teams that depend on ASP.NET. However, I do have plenty of regular functional tests for the feature that I plan to automate, and the plan for this area looks like this:

This is typical -- every feature area has a lot more tests defined for it than get will ever be run on any given build. We rely on testers using the builds for ad-hoc testing and writing automation to find bugs, and rely on automated tests to catch regressions in later builds. We also use full test passes like this to get a deeper sense of the product's quality at a few key intervals (such as earlier this month -- we wanted to catch isses in advance of the first large-scale Beta release of the product and get a sense of how much more work is needed to stabilize the product's quality before we ship).

And we did find bugs. In the above test plan, the very first test case failed during the full test pass. If a user clicked “Cancel” in the URL dialog, an empty string was returned by the method, rather than the initialURL parameter value. This has already been fixed, by the way.
