org.testng.TestNGException: No free nodes found in:[DynamicGraph

Question

I am using two methods of same class in testng, but it is not allowing me so... it is giving exception

org.testng.TestNGException: No free nodes found in:[DynamicGraph

my testng file is

<test name="User Data" preserve-order="true">
<classes>
    <class name="LoginTest">
        <methods>
            <include name="Login" />         
        </methods>
    </class>
<class name="xtr.chaut.test.PatientProfileTest">
      <methods>
            <include name="openPatientProfile"></include>
            <include name="checkUserData"></include>
       </methods>
</class>
  <class name="xtr.chaut.test.Login">
      <methods>
          <include name="logout"></include>
      </methods>
  </class>
</classes> 

here login and logout methods are from same class

please give me any solution for this

Thanks in advance

Answer 1

It appears that each class can only be declared once in the list, even if different methods are included on each declaration, otherwise you will see this error message :( Using latest TestNG 6.8.8. I was able to get this to work with @Test(priority=#) with the specific priority on each test method. See http://testng.org/doc/documentation-main.html#annotations.

My use case: crud tests for entities. Each Entity has its own test class with 4 methods (so I can test only a single entity CRUD in isolation), but I also want to run the overall suite (will fail due to integrity constraints and different generated ID keys unless they are run in exactly the right order).

Answer 2

I fixed it by adding parallel="true", below is the code

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Sanity Testing" parallel="true">
  <test name="VerifyTitles">
    <classes>
      <class name="WebDriver.VerifyTitles"/>
      <class name="WebDriver.VerifyTitles2"/>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->

Answer 3

I,ve got the same error, when I set number under zero for priority:

@Test(groups = "setup", priority = -1)

when I set for priority natural number, eg.

@Test(groups = "setup", priority = 1)

everything works fine.

Answer 4

Remove negative priority values for test cases. It worked for me.

Answer 5

I also got this error by defining a row of dependencies, tagged with a priority number. But then forgot a priority tag for one of the methods which are dependent on other.

E.g in the test class:

@Test
public void test1() throws Exception{ ...

@Test( priority=2 )
public void test2() throws Exception{ ...

@Test( priority=2, dependsOnMethods={"test2"})
public void test3() throws Exception{ ...

@Test( dependsOnMethods={"test3"})
public void test4() throws Exception{ ...

The test4 will cause the exception, as it is dependent on test3, but has no priority.
