我使用scalatest-maven-plugin最新1.0版本,source code here。尝试并行运行我的套件并使用以下配置:
<build><plugin>
<groupId>org.scalatest</groupId>
<artifactId>scalatest-maven-plugin</artifactId>
<version>1.0</version>
<configuration>
<reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
<junitxml>.</junitxml>
<filereports>WDF TestSuite.txt</filereports>
<htmlreporters>${project.build.directory}/html/scalatest</htmlreporters>
<parallel>true</parallel>
</configuration>
<executions>
<execution>
<id>test</id>
<goals>
<goal>test</goal>
</goals>
</execution>
</executions>
</plugin></build>
导致以下Maven构建错误:
[INFO]
[INFO] --- scalatest-maven-plugin:1.0:test (test) @ myproject ---
Exception in thread "ScalaTest-main" java.lang.IllegalArgumentException: ERROR: -c has been deprecated for a very long time and is no longer supported, to prepare for reusing it for a different purpos
e in the near future. Please change all uses of -c to -P.

基本上,scalatest-maven-plugin将-c
传递给最新的CLI,而不是正确的-P
..甚至更好-P10
,即要使用的线程数。
如何通过Maven将-P10
传递给最新的进程?我已经尝试在MAVEN_OPTS
环境变量或Maven CLI中直接设置它,但它没有被提取。
我也尝试过像这样配置scalatest-maven-plugin:
<configuration>
<argLine>-P10</argLine>
</configuration>
但是这个参数传递给了java进程而不是Scalatest,所以它也失败了。
答案 0 :(得分:2)
我创建了my own fork of the scalatest-maven-plugin,修复了并行问题并将其版本化为1.1-SNAPSHOT我还必须修复构建等等它全部被破坏了。我包含了一个可直接下载的编译tarball版本scalatest-maven-plugin_1.1-SNAPSHOT.tar.gz
然后测试它,使用my own version of a scala-maven-example分叉my own fork of the scalatest-maven-plugin并修改最新的示例代码以显示加载每个Suite的Thread Id和执行每个Suite的第一次测试的Thread Id。我还让当前线程在每个点中睡眠,最多10秒的随机时间,看看是怎么回事。所有scalatest套件都由单个线程加载,并且如果启用了并行,则并行执行。
这是使用<parallel>false</parallel>

As a user
I want to be able to create a simple thing and implicitly start it
So that I can then turn it off
And see that it is stopped
Feature: Simple thing state
Scenario: User stops thing when it's already on
Given An initialized thing, that has not been started
When User stops it again
Then We should see that it is stopped

- string matchers *** FAILED ***

- should even accept really long Strings
