How execution flow of testNG using TestNG.xml file works?

Question

I have two test classes and used TestNG annotation to execute them.

 

First class have annotation as 

@BeforeClasss 

@Test(priority = 1)

@Test(priority = 2)

@Test(priority = 3)

@AfterClass

 

 

Second class have annotation as 

@BeforeClasss 

@Test(priority = 1)

@Test(priority = 2)

@Test(priority = 3)

@AfterClass

 

When I put the classes in the tesNG.XML file and run it as a testNG suite.

The execution does not happen what I expect 

 

Actual Execution 

 First class

@BeforeClasss 

@Test(priority = 1)

 Second class

@BeforeClasss 

@Test(priority = 1)

 

From both class

@Test(priority = 2)

@Test(priority = 2)

 

 First class

@Test(priority = 3)

@AfterClass

 

 Second class

@Test(priority = 3)

@AfterClass

 

Then nothing happens my script test terminated

 

Expected Execution

 

First class

@BeforeClasss 

@Test(priority = 1)

@Test(priority = 2)

@Test(priority = 3)

@AfterClass

 

 Second class

@BeforeClasss 

@Test(priority = 1)

@Test(priority = 2)

@Test(priority = 3)

@AfterClass

 

Can anyone please tell how the execution flow happen in tsng.xml file

can you share your TestNG.xml file content as well?

I see that, in your TestNG.xml file, you have mentioned thread-count as 5. So, it is executing your two classes in parallel.

 

Remove it, or make it as 1 to get an output you are expecting.

<test thread-count="5" name="Test">

should be

<test thread-count="1" name="Test">

See the updated testNG xml file and still getting the same error.


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Test-class Suite"  >
    <listeners>
        <listener class-name="com.zoopla.qa.extendreport.ExtendReport" />

    </listeners>

 <test thread-count="1" name="Test">
        
        <classes>

            <class name="com.zoopla.qa.testcase.PracticeOne" />
            <class name="com.zoopla.qa.testcase.PracticeTwo" />

            <!-- <class name="com.zoopla.qa.testcase.HomePageTest" /> <class name="com.zoopla.qa.testcase.PropertyPageTest"
                /> <class name="com.zoopla.qa.testcase.SalePageTest" /> <class name="com.zoopla.qa.testcase.AgentDetailsPageTest"
                /> -->
        </classes>

    </test>
</suite>
