Hi guys, I have read the article about testing and I would like to test spark-testing-base with spark. Unfortunately I am not an expert with Maven so I don't get the tests to run. My project looks like this: pom.xml src/main/scala/com/test/spark/mycode.scala src/test/scala/com/test/spark/test.scala I can run 'mvn package' without problems. But it says [INFO] --- maven-compiler-plugin:3.1:testCompile (default-testCompile) @ mycode --- [INFO] Nothing to compile - all classes are up to date Why does my test not run? I have added the dependency as explained on the git for scala-testing-base and used the first example from its wiki. My pom.xml looks like this: <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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test.spark</groupId> <artifactId>mycode</artifactId> <version>0.0.1</version> <name>${project.artifactId}</name> <description>Simple wtest</description> <inceptionYear>2017</inceptionYear> <!-- change from 1.6 to 1.7 depending on Java version --> <properties> <maven.compiler.source>1.6</maven.compiler.source> <maven.compiler.target>1.6</maven.compiler.target> <encoding>UTF-8</encoding> <scala.version>2.11.5</scala.version> <scala.compat.version>2.11</scala.compat.version> <spark.version>1.6.1</spark.version> </properties> <dependencies> <dependency> <groupId>org.scala-lang</groupId> <artifactId>scala-library</artifactId> <version>${scala.version}</version> </dependency> <!-- Spark dependency --> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_${scala.compat.version}</artifactId> <version>${spark.version}</version> </dependency> <!-- Spark sql dependency --> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-sql_${scala.compat.version}</artifactId> <version>${spark.version}</version> </dependency> <!-- Spark hive dependency --> <dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-hive_${scala.compat.version}</artifactId> <version>${spark.version}</version> </dependency> <!-- spark-testing-base dependency --> <dependency> <groupId>com.holdenkarau</groupId> <artifactId>spark-testing-base_2.11</artifactId> <version>${spark.version}_0.6.0</version> <scope>test</scope> </dependency> <dependency> <groupId>org.scalactic</groupId> <artifactId>scalactic_2.11</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>org.scalatest</groupId> <artifactId>scalatest_2.11</artifactId> <version>3.2.0-SNAP5</version> <scope>test</scope> </dependency> </dependencies> <build> <sourceDirectory>src/main/scala</sourceDirectory> <testSourceDirectory>src/test/scala</testSourceDirectory> <!-- Create JAR with all dependencies --> <plugins> <plugin> <artifactId>maven-assembly-plugin</artifactId> <version>3.0.0</version> <executions> <execution> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> </plugin> <plugin> <!-- see http://davidb.github.com/scala-maven-plugin --> <groupId>net.alchim31.maven</groupId> <artifactId>scala-maven-plugin</artifactId> <version>3.2.2</version> <configuration> <scalaVersion>${scala.version}</scalaVersion> <scalaCompatVersion>${scala.compat.version}</scalaCompatVersion> </configuration> <executions> <execution> <phase>compile</phase> <goals> <goal>compile</goal> </goals> </execution> </executions> </plugin> <!-- for testing scala code --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.20</version> <configuration> <argLine>-Xmx2048m -XX:MaxPermSize=2048m</argLine> </configuration> </plugin> </plugins> </build> </project> Do you have any advise what I need to change in order to have my test run??
