如何通过maven插件设置Java / Scala测试的系统属性?

我想用2个不同的配置文件运行我的测试,每个配置文件都会导致我的scala测试代码以不同的方式执行。

我尝试配置maven-surefire和maven-scalatest插件:

        <plugin>
            <groupId>org.scalatest</groupId>
            <artifactId>scalatest-maven-plugin</artifactId>
            <version>1.0</version>
            <configuration>
                <systemProperties>
                    <spark.master>local</spark.master>
                </systemProperties>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.18.1</version>
            <configuration>
                <systemPropertyVariables>
                    <spark.master>local</spark.master>
                </systemPropertyVariables>
            </configuration>
        </plugin>

但看起来它们不起作用,在执行System.getProperty(“spark.master”)时,结果仍然为null。我该怎么做才能启用此设置?

对第一个答案的回应:

我已将surefire配置更改为以下内容:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.18.1</version>
            <executions>
                <execution>
                    <id>test</id>
                    <goals>
                        <goal>test</goal>
                    </goals>
                    <systemPropertyVariables>
                        <spark.master>${spark.master}</spark.master>
                    </systemPropertyVariables>
                </execution>
            </executions>
            <configuration>
                <forkCount>1</forkCount>
            </configuration>
        </plugin>

但显然是在错误的地方。 Maven给了我这个错误:

[ERROR]     Malformed POM /home/peng/git/datapassport/pom.xml: Unrecognised tag: 'systemPropertyVariables' (position: START_TAG seen ...</goals>\n                        <systemPropertyVariables>... @170:50)  @ /home/peng/git/datapassport/pom.xml, line 170, column 50 -> [Help 2]

答案 0 :(得分:1)

(a)如果您使用JUnit - 将其版本升级到4.7或更高版本并指定显式提供程序:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.18.1</version>
    <dependencies>
        <dependency>
            <groupId>org.apache.maven.surefire</groupId>
            <artifactId>surefire-junit47</artifactId>
            <version>2.18.1</version>
        </dependency>
    </dependencies>

(b)在surefire插件配置中指定

<forkCount>1</forkCount>

(c)使用plugun的执行maven机制来运行两个不同的配置文件

<executions>
    <execution>
        <id>tests-1</id>
        <goals><goal>test</goal></goals>
        <configuration>
            <systemProperyVariables ... />
        </configuration>
    </execution>
    <execution>
        <id>tests-2</id>
        <goals><goal>test</goal></goals>
        <configuration>
            <systemProperyVariables ... />
        </configuration>
    </execution>
