any idea went wrong here?.

following sample test code. think basic test-case can write.

import org.ops4j.pax.exam.configuration; import org.ops4j.pax.exam.option; import org.ops4j.pax.exam.spi.reactors.examreactorstrategy; import org.ops4j.pax.exam.spi.reactors.perclass; import org.ops4j.pax.exam.testng.listener.paxexam; import org.osgi.framework.bundlecontext; import org.testng.annotations.listeners; import org.testng.annotations.test;  import javax.inject.inject;  import static org.testng.assert.assertnotnull; import static org.ops4j.pax.exam.coreoptions.*;   @listeners(paxexam.class) @examreactorstrategy(perclass.class) public class sampletest {      @inject     bundlecontext bundlecontext;      @configuration     public option[] config() {          return options(                 mavenbundle().artifactid("testng").groupid("org.testng").versionasinproject()         );     }      @test     public void testbundlecontextstatus() {         assertnotnull(bundlecontext, "bundle context null");     } }

here dependencies i've used.

<dependency>             <groupid>org.testng</groupid>             <artifactid>testng</artifactid>             <version>${testng.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.ops4j.pax.exam</groupid>             <artifactid>pax-exam</artifactid>             <version>${exam.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.ops4j.pax.exam</groupid>             <artifactid>pax-exam-container-native</artifactid>             <version>${exam.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.ops4j.pax.exam</groupid>             <artifactid>pax-exam-testng</artifactid>             <version>${exam.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.ops4j.pax.exam</groupid>             <artifactid>pax-exam-link-mvn</artifactid>             <version>${exam.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.ops4j.pax.url</groupid>             <artifactid>pax-url-aether</artifactid>             <version>${url.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.slf4j</groupid>             <artifactid>slf4j-api</artifactid>             <version>${slf4j.api.version}</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>org.ow2.spec.ee</groupid>             <artifactid>ow2-jta-1.1-spec</artifactid>             <version>${ow2.jta.spec.version}</version>             <scope>test</scope>         </dependency>

after changing testng depenedncy version 6.3.1 worked correctly. latest released version 6.9.6 issue there.

the latest edit question contains answer. pax exam 4.6.0 compiled testng 6.8.17, , apparently there has been incompatible api change in testng 6.9.x.

pax exam directly uses internal classes of testng lack of better alternative.

you're better off using pax exam junit in general. junit better integrated , has lot more test coverage , usage in ops4j , other downstream projects.
