How to use getTestResult method of org.testng.Interface IInvokedMethod class

You have to rework your tests:

@BeforeSuite is only called once by suite. You have 2 classes then the first has the dao instanced, the other not (NPE in this case).

One option is to use static for your dao. Another solution could be to put documentDao = DAOFactory.getDocumentDAO(); into @BeforeClass. But you can find many other (better) solutions.

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

The transaction needs to be started in the same thread, here are more details:

Spring3/Hibernate3/TestNG: some tests give LazyInitializationException, some don't

A couple of ideas:

Even if you are running the tests programmatically, you should be able to invoke TestNG on a testng.xml file. Add parameters to the file like so (from the documentation):

<suite name="My suite">
   <parameter name="parameter"  value="Foo"/>
   <test name="Courier Test" />
   < ... >

If for some reason you aren't using a testng.xml file, you can use a DataProvider, either as a method within the test class or as a static class, depending on what you need to do. Examples below (also from the documentation).

DataProvider inside the class:

//This method will provide data to any test method that declares
//that its Data Provider is named "test1"
@DataProvider(name = "test1")
public Object[][] createData1() {
   return new Object[][] {
     new Object[] { "Parameter" }
   }
}

//This test method declares that its data should be supplied 
//by the Data Providernamed "test1"
@Test(dataProvider = "test1")
public void Courier_Test(String parameter) {
 System.out.println(parameter);
} 

DataProvider in external class:

public static class StaticProvider {
  @DataProvider(name = "create")
  public static Object[][] createData() {
    return new Object[][] {
      new Object[] { "Parameter" }
    }
  }
}

public class Courier {
  @Test(dataProvider = "create", dataProviderClass = StaticProvider.class)
  public void Courier_Test(String parameter) {
    // ...
  }
}

You need to include the .class of packageName.className in your classpath (as the error says). So when you run the .xml file via a command line it should look something like java -cp %CLASSPATH%;path/to/packageName.className.class org.testng.TestNG path/to/testng.xml.

Depending on what is or isn't already in your class path, you'll also need to include the paths to the libraries. Because this can be a chore to type in, I highly suggest saving this as a shell script or batch file depending on your OS.

A FreeMarker template would look something like this:

public class ${className} {
    @Test(groups="${testGroups}")
    public void ${testMethodName}() {
        <#list methods as m>
        ${m}
        </#list>   
    }
}

It would be filled from a context, essentially a hashmap with className, testGroups, etc. entries, that would be read from your XML file. methods would be a Collection (like a list), also read from the XML file.

There are many other templating libraries, of course; this is just an example.

You can use the dependsOnMethods or dependsOnGroups annotation parameter in your other test methods:

@Test(dependsOnMethods = {"stopTestingIfThisFailed"})
public void testAnotherTestMehtod()  {

}

JavaDoc of the dependsOnMethods parameter:

The list of methods this method depends on. There is no guarantee on the order on which the methods depended upon will be run, but you are guaranteed that all these methods will be run before the test method that contains this annotation is run. Furthermore, if any of these methods was not a SUCCESS, this test method will not be run and will be flagged as a SKIP. If some of these methods have been overloaded, all the overloaded versions will be run.

See https://testng.org/doc/documentation-main.html#dependent-methods

All independent methods (that do not have @dependsOnMethods dependency) will be executed first. Then methods with dependency will be executed. If there is ambiguity in execution order even after this ordering, priority comes into picture.

This is the ordering scheme:

1. Execute all independent methods (methods without @dependsOnMethods annotation)
2. If there is ambiguity in this ordering use priority to resolve ambiguity for independent methods
3. Execute dependent methods in order of dependency
4. If there is ambiguity in this ordering use priority to resolve ambiguity for dependent methods
5. If there is still ambiguity (due to not using priority or two methods having same priority) order them based on alphabetical order.

Now all ambiguity is resolved since no two methods can have the same name.

The dataProvider expects method cptoadsLogin to get parameters.

The data provider is trying to pass 2 parameters but the method cptoadsLogin takes 0

You need to change the method signature to receive 2 parameters

@Test(dataProvider = "toadsLogin")
public void cptoadsLogin(String user, String pwd) throws Exception
{
    ToadsLogin tlogin=new ToadsLogin(driver);
    tlogin.unpwd(user, pwd);
    tlogin.clikonLogin();
    Thread.sleep(5000);
    driver.close();
}

user will have the value from data1[i][0] and pwd will have the value from data1[i][1]
