Passing output of one test method to another method testng

Question

I have to write the following unit test cases in testng:

1. saveProductTest which would return productId if product details are saved successfully in DB.

2. modifyProductTest, it should use previously saved productId as a parameter.

I am taking the product details input(PrdouctName, ReleaseDate) for saveProductTest and modifyProductTest method from an XML file using testNg data providers.Since productId is generated in save method, I have to pass it to the modify method.

What is the best way to pass output of one test method to another method in testng.

Answer 1

With the ITestContext object. It's a object available globally at the Suite context and disponible via parameter in each @Test.

For example:

@Test 
public void test1(ITestContext context, Method method) throws Exception {
    // ...
    context.setAttribute(Constantes.LISTA_PEDIDOS, listPaisPedidos);
    // ...
}

@Test
public void test2(ITestContext context, Method method) throws Exception {
    List<PaisPedido> listPaisPedido = (List<PaisPedido>)
    context.getAttribute(Constantes.LISTA_PEDIDOS);
    // ...
}
