Try not to run tests in Idea but in SBT. Idea sometimes mess up something. – Alliber

Answer 1

I got the resolution. Thanks all for you reply.

There was a problem with my Scatatest version.

I am using Scala version 11 and scalatest version is not compatible with with Scala version.

libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.1" % "test"

Above line added in .sbt file and refreshed. Now it works fine as expected.

Answer 2

I was able to mitigate the error by moving to scala 2.12.11 from 2.12.13 and here's how my pom looks like:

    <dependency>
        <groupId>org.scalatest</groupId>
        <artifactId>scalatest_2.12</artifactId>
        <version>3.0.8</version>
        <scope>test</scope>
    </dependency>

        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.7</version>
          <configuration>
            <skipTests>true</skipTests>
          </configuration>
        </plugin>

        <plugin>
          <groupId>org.scalatest</groupId>
          <artifactId>scalatest-maven-plugin</artifactId>
          <version>2.0.0</version>
          <configuration>
            <reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
            <junitxml>.</junitxml>
            <filereports>WDF TestSuite.txt</filereports>
          </configuration>
          <executions>
            <execution>
              <id>test</id>
              <goals>
                <goal>test</goal>
              </goals>
            </execution>
          </executions>
        </plugin>`
