Scalatest Maven插件“没有执行测试”

Question

我试图在Maven上使用鳞状和火花试验底座进行集成测试。Spark作业读取CSV文件，验证结果，并将数据插入数据库。我试图通过输入已知格式的文件来测试验证，并查看它们是否失败以及如何失败。这个特定的测试只是确保验证通过。不幸的是，最严重的人找不到我的测试。

相关pom插件：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skipTests>true</skipTests>
            </configuration>
        </plugin>
        <!-- enable scalatest -->
        <plugin>
            <groupId>org.scalatest</groupId>
            <artifactId>scalatest-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
                <wildcardSuites>com.cainc.data.etl.schema.proficiency</wildcardSuites>
            </configuration>
            <executions>
                <execution>
                    <id>test</id>
                    <goals>
                        <goal>test</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

这是考试课：

class ProficiencySchemaITest extends FlatSpec with Matchers with SharedSparkContext with BeforeAndAfter {
    private var schemaStrategy: SchemaStrategy = _
    private var dataReader: DataFrameReader = _

    before {
        val sqlContext = new SQLContext(sc)
        import sqlContext._
        import sqlContext.implicits._

        val dataInReader = sqlContext.read.format("com.databricks.spark.csv")
                                            .option("header", "true")
                                            .option("nullValue", "")
        schemaStrategy = SchemaStrategyChooser("dim_state_test_proficiency")
        dataReader = schemaStrategy.applySchema(dataInReader)
    }

    "Proficiency Validation" should "pass with the CSV file proficiency-valid.csv" in {
        val dataIn = dataReader.load("src/test/resources/proficiency-valid.csv")

        val valid: Try[DataFrame] = Try(schemaStrategy.validateCsv(dataIn))
        valid match {
            case Success(v) => ()
            case Failure(e) => fail("Validation failed on what should have been a clean file: ", e)
        }
    }
}

当我运行mvn test时，它找不到任何测试并输出以下消息：

[INFO] --- scalatest-maven-plugin:1.0:test (test) @ load-csv-into-db ---

更新

通过使用：

<suites>com.cainc.data.etl.schema.proficiency.ProficiencySchemaITest</suites>

而不是：

<wildcardSuites>com.cainc.data.etl.schema.proficiency</wildcardSuites>

我可以让那一项测试运行。显然，这并不理想。wildcardSuites可能坏了，我要在GitHub上开一张票，看看会发生什么。

Answer 1

这可能是因为项目路径中有一些空格字符。删除项目路径中的空间，可以成功地发现测试。希望能帮上忙。

Answer 2

尝试将junit排除为传递依赖关系。为我工作。下面的示例，但是请注意Scala和Spark版本是特定于我的环境的。

   <dependency>
        <groupId>com.holdenkarau</groupId>
        <artifactId>spark-testing-base_2.10</artifactId>
        <version>1.5.0_0.6.0</version>
        <scope>test</scope>
        <exclusions>
            <!-- junit is not compatible with scalatest -->
            <exclusion>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
            </exclusion>
        </exclusion>
    </dependency>

Answer 3

对我来说，这是因为我没有使用以下插件：

​

<plugin>
        <groupId>org.scala-tools</groupId>
        <artifactId>maven-scala-plugin</artifactId>
        <executions>
          <execution>
            <goals>
              <goal>compile</goal>
              <goal>testCompile</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <scalaVersion>${scala.version}</scalaVersion>
          <args>
            <arg>-target:jvm-1.8</arg>
          </args>
        </configuration>
      </plugin>
