How to use TestNGContentHandler class of org.testng.xml package

To verify if the WebElement is selected or not you can try:

    String attr = driver.findElement(By.id("user-settings-price-preview-checkbox")).getAttribute("class");
    if(attr.contains("active"))
        System.out.println("WebElement selected");
    else
        System.out.println("WebElement NOT selected");

To run a single test method in Maven, you need to provide the command as:

mvn test -Dtest=TestCircle#xyz test

where TestCircle is the test class name and xyz is the test method.

Wild card characters also work; both in the method name and class name.

If you're testing in a multi-module project, specify the module that the test is in with -pl <module-name>.

For integration tests use it.test=... option instead of test=...:

mvn -pl <module-name> -Dit.test=TestCircle#xyz integration-test

Try @AfterTest(alwaysRun = true).

From the TestNG doc:

For after methods (afterSuite, afterClass, ...): If set to true, this configuration method will be run even if one or more methods invoked previously failed or was skipped.

I don't see any <javac> task to compile the tests. Don't you have to do that first?

And I'm not sure where you think java.class.path is coming from, but I'd set it explicitly inside your Ant build.xml

Here's a generic build.xml that I use, including the testing task. Give it a look and see if it can help you:

The constructor does not exist. Use ZonedDateTime.now() or one of the equivalents. See the relevant JavaDoc.

I think what you want is parameterized tests. It's available if you're using JUnit4 (or TestNG). Since you mention JUnit, you'll want to look at the @RunWith(Parameterized.class) and @Parameters annotations' documentation.

Unpack it and place somewhere you can find it. In my example, I will assume you will place it to C:\Selenium\iexploredriver.exe

Then you have to set it up in the system. Here is the Java code pasted from my Selenium project:

File file = new File("C:/Selenium/iexploredriver.exe");
System.setProperty("webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();

Basically, you have to set this property before you initialize driver

Reference:

• Driver executable must be set by the webdriver.ie.driver system property

I also suggest looking at JCommander (http://jcommander.org/), written by the author of TestNG. I have used it successfully in many command line applications.

Try extending XmlTest in your test class and call setName(). I extended XmlSuite and used setName to name my "test suite" which is a class with multiple tests defined in it and that worked for me. In fact I just tried what I suggested on the same class and now it's called a test with the correct name. I'm not sure why the ITest interface is being ignored as I also tried that approach without success.
