Method not getting invoked within the test
testng user
I have a test as below
@Test(groups="A"), dataProvider="myProvider")
public void testMyCode(MyData data) throws Exception
{
//Call another method from the test
boolean result=myMethod(List of parameters)
}
myMethod is not even called and I could see the below exception.
java.lang.NullPointerException

Pls. find the sample code.
Class MyTest
{
@Parameters ({ "a","b","c})
@BeforeSuite(groups= {"All"},alwaysRun=true)
public void setValues(String a, String b, String c)
{
this.a=a;
this.b=b;
this.c=c;
MyHelper obj=new MyHelper(a,b,c);
}
@BeforeGroups(groups={"A","B","C","D"} )
{
//Connect to the database and fetch values
}
@Test(groups="A"), dataProvider="myProvider")
public void testMyCode(MyData data) throws Exception
{
//Call another method from the test
boolean result=obj.myMethod(data.getA(), data.getB(),
data.getC());
}
@AfterGroups(groups={"A","B","C","D"} )
{
//Start and stop multiple servers.
}
@DataProvider(name="myProvider")
public Iterator getData()
{
return new MyIterator("A");
}
A) I figured out that the MyHelper obj is "NULL" when called in the
tests. But in the before suite it is created. Not sure why it is NULL
in the test method. I am not sure by resolving the issue we can get
rid of the exception I posted above.
I would greatly appreciate if we have more clear documentation in
testng.org site for different configuration methods (with examples).
Most of the issues I faced regarding the usage of BeforeGroups
annotation is faced by lot of other members in the group. I got
solutions reading the posts in the group but felt that having a good
documentation would greatly help everyone.
Thanks !!

From the test output I noticed that BeforeSuite and BeforeGroups
method are called at the same time and hence the BeforeGroups method
could not get the values of configuration parameters passed from
testng.xml file in the BeforeSuite method.
Thanks.

Hello Cedric,
Pls. find the sample code.
Class MyTest
{
@Parameters ({ "a","b","c})
@BeforeSuite(groups= {"All"},alwaysRun=true)
public void setValues(String a, String b, String c)
{
this.a=a;
this.b=b;
this.c=c;
MyHelper obj=new MyHelper(a,b,c);
testng user
I see no issues in the dataprovider. The only issue I see now is the
values set in the setValues() method ( which are mostly parameters to
connect to DB and server and the session information) is not available
in the test method for some reason. I have multiple groups which
access the same information "A", "B","C" and "D".
I am surprised to see that the same configuration parameters are
available for group "B" which is called after group "A".
Thanks..

I already removed the variable and moved it to beforeGroup("A").
MyHelper object was not declared inside the BeforeSuite in my actual
code. Sorry for the mistake.
Thanks.
