testng 是否运行多线程？

Question

I have a java maven project that I want tested using multithreads. I have the testng.xml in src/test and the maven surefire plugin is configured to used it. Just like this page: http://maven.apache.org/surefire/maven-surefire-plugin/examples/testng.html

edit: added surefire pom entry

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-surefire-plugin</artifactId>
 <version>2.12.4</version>
 <configuration>
  <suiteXmlFiles>
   <suiteXmlFile>src/test/testng.xml</suiteXmlFile>
  </suiteXmlFiles>
 </configuration>
</plugin>

I am using surefire 2.12.4.

This is my testng.xml file

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
 <suite name="Testng" parallel="methods" thread-count="3">
  <test name="all" annotations="JDK5">
    <packages>
        <package name="my.package.*"/>
    </packages>
  </test>
</suite>

Inside several test methods I have a print statement:

System.out.println(Thread.currentThread().getName());

That always has the same output every run (pool-1-thread-1). If testng was running parallel then there would be different threads running.

My questions are: why is testng not running multithreaded? and is there a better way to check if testng is running multithreaded?

edit: classes or methods

When I run with threads each test class seems to run in it's own thread, but not each method. In the testng.xml I set parallel="methods" so it should do it per method. Can it not do per method?

Answer 1

I found the answer, I wasn't giving it enough threads. Since my project has many tests testng would not make new threads per method. I changed it to 10 threads and that fixed it.

Answer 2

TestNG will not be running in parallel in this case. You need to define ThreadLocal to define different browsers in threads. Use: ThreadLocal, and define the browsers in different instances. You will be getting different browser ID's in this case..
