Mstest name instead Data Row with Data-Driven testing

问题

I use MsTests and Data Driven approach for testing. (Excel is data storage for tests)

tests result dont provide any information about tests data. For example:

Result look as: testname (Data row 5). And it is not clear for me.

How can i customise output test result? For example testname (Test data (word, number, or row named))

回答1:

I found only one solution:

I have MyData.xlsx file with 1000 rows. Simple logic: "A" column = 1, "B" column = A*2+2.

Rows 5,6,7 and 11,12,13 conteins zero for make a failed results.

SourceCode of my Test:

public TestContext TestContext { get; set; }

    [TestMethod]
    [DataSource("System.Data.Odbc", "Dsn=Excel Files;dbq=|DataDirectory|\\TestData\\MyData.xlsx;", "TestDataSheet$", DataAccessMethod.Sequential)]
    public void ExcelDataSource1000Items()
    {
        var errorMessage = "Passed";

        int valueA = Convert.ToInt32(TestContext.DataRow["valueA"]);
        int valueB = Convert.ToInt32(TestContext.DataRow["valueB"]);
        try
        {
            Assert.AreEqual(valueA * 2 + 2, valueB);
        }
        catch (Exception exception)
        {
            errorMessage = exception.Message;
        }
        TestContext.WriteLine(string.Format("valueA: {0}, valueB: {1}, AssertResult: {2}", valueA, valueB, errorMessage));
    }

After execution test from MsTest command line (for generating *.trx file) with parameters: /testcontainer, /testsettings, /resultsfile we generate *.trx file with test results.

And if we open this *.trx file, we can see TextMessages:

These TextMessages can be parsed to generate test report. (for example)

P.S. Sorry, i can not add screenshots, because i dont have 10 or more reputation =\
