如何从数据提供程序中替换硬编码值

Question

我正在寻找从@DataProvider public static Object [] [] sauceBrowserDataProvider中删除（替换）硬编码浏览器/ OS / Version值的建议。代码示例：

    @DataProvider(name = "hardCodedBrowsers", parallel = true)
    public static Object[][] sauceBrowserDataProvider(Method testMethod) {
    return new Object[][]{

            **new Object[]{"firefox", "55.0", "Windows 10"},
            new Object[]{"chrome", "65.0", "Windows 10"},**

    };}


@Test( dataProvider = "hardCodedBrowsers")

    public void createDriver(String browser, String version, String os)
        throws Exception {
        Class<? extends TestRemote> SLclass = this.getClass();

        DesiredCapabilities capabilities = new DesiredCapabilities();

        // set desired capabilities to launch appropriate browser on Sauce
        capabilities.setCapability(CapabilityType.BROWSER_NAME, browser);
        capabilities.setCapability(CapabilityType.VERSION, version);
        capabilities.setCapability(CapabilityType.PLATFORM_NAME, os);    

        capabilities.setCapability("seleniumVersion", "3.8.1");
        capabilities.setCapability("name", SLclass.getSimpleName());
        capabilities.setCapability("screenResolution", "1920x1080");

        driver = (new RemoteWebDriver(new URL("http://" + SAUCE_USERNAME + ":" + SAUCE_ACCESS_KEY + "@ondemand.saucelabs.com:80/wd/hub"), capabilities));

       configRead = new ConfigFileReader();

       propertyRead = new PropertyLoader();

       baseUrl = propertyRead.getProperty("site.url");

       app = new Application(driver);

       getURL();

    }

这是Java / TestNg / Jenkins / Saucelabs上的selenium项目

Answer 1

最简单的方法是将组合（浏览器/操作系统/版本）移动到数据源，如excel电子表格或csv或json / yaml / xml，并让@DataProvider从那里读取它们。

Answer 2

你可以使用QAF TestNG extension。它提供不同的inbuilt data-providers来加载来自不同数据源的测试数据，如xml，json，excel，properties，database。使用QAF，您可以设置不同的数据源，如下所示：

@QAFDataProvider (dataFile = "resources/data/logintestdata.csv")
@QAFDataProvider(dataFile = "resources/data/testdata.xls")
@QAFDataProvider(dataFile = "resources/data/testdata.xls", sheetName="login")
@QAFDataProvider(dataFile = "resources/data/testdata.xls", key="login") //excel with data table
@QAFDataProvider(dataFile = "resources/data/logintestdata.json")
@QAFDataProvider(key="login.data") //xml key
@QAFDataProvider(sqlQuery = "select col1, col2 from tbl") // database
@QAFDataProvider(dataFile = "resources/data/logintestdata.txt")

此外，你可以switch data-provider没有改变代码。除此之外，它还具有许多用于网络，移动（使用selenium，appium）和网络服务的黑盒测试功能。
