Build getting succeeded, but test suite is not getting executed from pom.xml with mvn test

I am trying to execute the maven test from pom.xml . All my test are written in testng.xml file and I am able to invoke testng.xml file alone and test is getting executed as expected. But when I try to execute testng.xml from pom.xml using mvn test, though I have called testng.xml file from maven sure fire plugin, only the build is getting succeed and test is not getting executed.
Please find my pom.xml

Thank you to all, and especially to Raghav Pal, and his YouTube channel.
After all steps, it was needed to perform "clean verify". After this operation, the report has been successfully generated.

After you need to clean your project -> run via mvn clear verify. That's all.

mvn appengine:run fails to execute goal com.google.cloud.tools:appengine-maven-plugin:2.2.0:run mvn appengine:deploy works fine

I am following the instructions from https://cloud.google.com/appengine/docs/standard/java/building-app/static-content I can deploy my changes and check them using gcloud app browse, but I cannot make the local development environment work.
Running mvn appengine:run -DskipTests returns the following error, and trying mvn package clean beforehand doesn't change it

I had the same build error because of using unmatched JDK version.
Check your JDK version with "java -version". Probably you should use Java8(Java1.8) instead of Open JDK13.

I did some mistake in my pom.xml file, But I don't know..
Pls, let me know your suggestion..
Thank you.

Check this answer: https://stackoverflow.com/a/4088861/5572007
You shouldn't use "-shaded" suffix.
Quote: "[Shaded plugin] normally renames that jar to target/original-artifact-version.jar, and gives the shaded JAR the name target/artifact-version.jar". You can check your target folder for names of generated jar files.

Check that jar file corresponding to template really exists:
${project.build.directory}/${artifactId}-${version}-shaded.jar
You can replace this template to hardcoded full path to jar file and run build to verify all correct.

Additional info: Im using Eclipse Kepler, my Run Configuration looks like this:
tomcat7:exec-war -e
I also tried with the commando line, tried :exec-war-only but nothing worked.
I searched and tried different things for days now, so any help is much appreciated! : ]

The NPE is because the plugin does not find the packaged war file, I fixed that error by explicitly adding the package phase to the build, so for example:
mvn clean package tomcat7:exec-war
any phase that produce the war package fits well for avoiding the NPE: package, install, deploy, etc.
So, in your case, where you use a Run Configuration in Eclipse, just add package before tomcat7:exec-war -e

I have a similar issue with version 2.2 of the plugin, but I got it run with 2.1 according to this tutorial.

There is a version 2.3 now where the problem from 2.2 has been fixed!
(had some problems with 2.1 because it is so old)
Sadly its only a snapshot version and needs to be fetched from Apache Snapshots Repository. To get it you need to put this into your pom:
<pluginRepositories>
<pluginRepository>
<id>apache.snapshots</id>
<name>Apache Snapshots</name>
<url>http://repository.apache.org/snapshots</url>
<releases>
<enabled>false</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
Then you can use the new version <version>2.3-SNAPSHOT</version>

I received this error with spring boot application. I had to spend quite sometime so putting it here that below plugin needs to be included
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
Also packaging type should be jar
<packaging>jar</packaging>
Start-class should be defined as your main class
<start-class>com.edu.schoolT.SchoolWeb</start-class>
main class or class annotated with #SpringBootApplication should extend SpringBootServletInitializer. For further info...
Create a deployable war file

I have fixed similar issue in my project and given reference below link
tomcat7-maven-plugin custom server.xml
