Maven throws error while running testng test cases

问题

I have steup Eclipse + Maven + TestNG and I intend to run Selenium Test cases.

This is my POM File:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>MyGroupId</groupId>
<artifactId>TestSuite</artifactId>
<version>0.0.1-SNAPSHOT</version>
<dependencies>
    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>2.32.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.maven.surefire</groupId>
        <artifactId>surefire-testng</artifactId>
        <version>2.14.1</version>
    </dependency>
    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.8.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>
</project>

Now when I try to run Maven test, I get following error:

... 10 more

Results :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

Can someone suggest me what's that I am missing here.

Thanks in advance.

You have to define the maven-surefire-plugin in the pluginManagement section like the following:

  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.14.1</version>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

To use testng in relationship with the maven-surefire-plugin you usually only need to add testng as a dependency nothing more.

Furthermore remove the dependency you've given:

<dependency>
    <groupId>org.apache.maven.surefire</groupId>
    <artifactId>surefire-testng</artifactId>
    <version>2.14.1</version>
</dependency>

Apart from the above this is looking more like an integration tests which is the job of maven-failsafe-plugin and not of maven-surefire-plugin.

<plugin>
  <artifactId>maven-failsafe-plugin</artifactId>
  <executions>
    <execution>
      <goals>
        <goal>integration-test</goal>
        <goal>verify</goal>
      </goals>
    </execution>
  </executions>
</plugin>

This means your tests (presumably integration tests based on the selenium dependency) can be run by using:

mvn verify

Maybe will help somebody. Me helped - change version dependency of testng

It was:

<dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.11</version>
    <scope>test</scope>
</dependency>

And has become:

 <dependency>
    <groupId>org.testng</groupId>
    <artifactId>testng</artifactId>
    <version>6.10</version>
    <scope>test</scope>
</dependency>

回答3:

I also had an issue that resulted in this error, but for me it turned out to be missing file access rights for the account running the tests to the test folder.

Might be something to check out

回答4:

changing the testNG dependency version in pom.xml from 6.14.3 to 6.10 will help out in avoiding the exception cases.
