Question

Does anyone know of a tool that will spit out a list of all methods with the [TestMethod] attribute within a solution?

What we're trying to accomplish is a review, with the customer, of our Unit Tests (names, not pass/fail status) against the Requirements. We are using VSTS 2008 and Scrum for Team Systems, so I wasn't sure if this was something that was built in somewhere, or if it's a tool I just need to toss together for our purposes. Any help would be great. Thanks.

Was it helpful?

Solution

VS essentially offers this ability for free by generating the TRX file to summarize the results of a test run. There are a number of different ways to run all tests in a project but pick one and off mstest will go running each method with the [TestMethod] attribute and producing a UnitTestResult in the results file.

What you're asking for is essentially what the Test Results window shows you after a completed Test Run. If you're looking for something external to VS, you could always run a simple XSLT transform against the Test Results (.trx) file giving you a customized summary. Here's a very rough sample which proofs the concept, generating an HTML document containing an unordered list with a list item (test name and result) for each unit test:

<?xml version='1.0'?>
<xsl:stylesheet version="1.0"
            xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
            xmlns:vs="http://microsoft.com/schemas/VisualStudio/TeamTest/2006">

    <xsl:template match="/">
        <html>
            <head>
                <style type="text/css">

                    body { font-family: verdana; font-size: 12px; }

                    .pass { color: green; }
                    .nopass { color: red; }

                    h1 { font-size: 13px; margin: 3px; }

                    ul { margin: 3px 20px 3px 40px; }
                </style>
            </head>
            <body>

                <h1>Test Results</h1>
                <ul>

            <xsl:apply-templates select="//vs:Results//vs:UnitTestResult" />

                </ul>
            </body>
        </html>

    </xsl:template>
    <xsl:template match="vs:UnitTestResult" >
        <li>
            <xsl:value-of select="@testName" />
            &#160;

            <xsl:variable name="Result">
                <xsl:choose>
                    <xsl:when test="@outcome='Passed'">pass</xsl:when>
                    <xsl:otherwise>nopass</xsl:otherwise>
                </xsl:choose>
            </xsl:variable>

            <b class="{$Result}">
                <xsl:value-of select="@outcome" />
            </b>
        </li>

    </xsl:template>
</xsl:stylesheet>
