How to run all JUnit tests in a category/suite with Ant?
提问by Jonik
I'm using JUnit Categories and ClassPathSuite in a setup similar to that described in this answer. To recap:
我在类似于此答案中描述的设置中使用 JUnit Categories 和 ClassPathSuite 。回顾一下：
public interface FastTests {
}
@RunWith(Categories.class)
@Categories.IncludeCategory(FastTests.class)
@Suite.SuiteClasses(AllTests.class)
public class FastTestSuite {
}
@RunWith(ClasspathSuite.class)
public class AllTests {
}
...where AllTests makes use of the ClasspathSuitelibrary.
...其中 AllTests 使用ClasspathSuite库。
A test class that's part of the FastTests category would look like this:
属于 FastTests 类别的测试类如下所示：
@Category(FastTests.class)
public class StringUtilsTest {
// ...
}
When I run "FastTestSuite" in my IDE, all tests with the FastTests annotation are executed, nice & smooth:
当我在 IDE 中运行“FastTestSuite”时，所有带有 FastTests 注释的测试都会被执行，非常流畅：
Now, I want to do the same thing with Ant. (To my surprise, I couldn't easily find instructions for this on SO.) In other words, I need an Ant target that runs all tests with the FastTests annotation.
现在，我想对 Ant 做同样的事情。（令我惊讶的是，我无法在 SO 上轻松找到相关说明。）换句话说，我需要一个 Ant 目标来运行所有带有 FastTests 注释的测试。
I've tried some simplistic approaches using <test>or <batchtest>...
我尝试了一些简单的方法使用<test>或<batchtest>...
<junit showoutput="true" printsummary="yes">
<test name="fi.foobar.FastTestSuite"/>
<formatter type="xml"/>
<classpath refid="test.classpath"/>
</junit>
... but no luck, so far.
......但到目前为止还没有运气。
Edit: Besides the IDE, it works fine with JUnitCore on the command line:
编辑：除了 IDE，它在命令行上与 JUnitCore 一起工作正常：
$ java -classpath "classes:WebContent/WEB-INF/lib/*" org.junit.runner.JUnitCore fi.foobar.FastTestSuite
.............
Time: 0.189
OK (13 tests)

Right, I got it working with <batchtest>quite simply:
是的，我<batchtest>很简单地使用它：
<junit showoutput="true" printsummary="yes" fork="yes">
<formatter type="xml"/>
<classpath refid="test.classpath"/>
<batchtest todir="${test.reports}">
<fileset dir="${classes}">
<include name="**/FastTestSuite.class"/>
</fileset>
</batchtest>
</junit>
I had tried <batchtest>earlier, but had made the silly mistake of using "**/FastTestSuite.java"instead of "**/FastTestSuite.class"in the <include>element... Sorry about that :-)
我之前试过<batchtest>，但犯了一个愚蠢的错误"**/FastTestSuite.java"，"**/FastTestSuite.class"在<include>元素中使用而不是......对此感到抱歉:-)
NB: it's necessary to set fork="yes"(i.e., run the tests in a separate VM); otherwise this will also produce "initializationError" at java.lang.reflect.Constructor.newInstance(Constructor.java:513) like <test>(see comments on the question). However, I couldn't get <test>working even with fork="yes".
注意：有必要设置fork="yes"（即，在单独的 VM 中运行测试）；否则，这也会在 java.lang.reflect.Constructor.newInstance(Constructor.java:513) 处产生“initializationError”，例如 <test>（请参阅对问题的评论）。但是，<test>即使使用fork="yes".
The only shortcomingis that this produces just one JUnit XML report file (TEST-fi.foobar.FastTestSuite.xml) which makes it look like all the (hundreds) of tests are in one class (FastTestSuite). If anyone knows how to tweak this to show the tests in their original classes & packages, please let me know.
该唯一的缺憾是，这将产生只有一个JUnit的XML报告文件（TEST-fi.foobar.FastTestSuite.xml），这使得它看起来像所有的（几百个）的测试是在一个类（FastTestSuite）。如果有人知道如何调整它以显示其原始类和包中的测试，请告诉我。

I found a workaround to use ant's junittask to run test of a specific Category:
我找到了一种使用 ant 的junit任务来运行特定测试的解决方法Category：
<target name="test" description="Run Selenium tests by category">
<fail unless="category.name" message="Please specify 'category.name' property"/>
<junit showoutput="true" printsummary="true" fork="true">
<formatter type="xml"/>
<classpath refid="test.classpath"/>
<batchtest todir="${test.reports}" haltonfailure="false">
<fileset dir="${classes}">
<!-- regex '^\s*@Category' part added to ensure @Category annotation is not commented out -->
<containsregexp expression="^\s*@Category.*${category.name}"/>
</fileset>
</batchtest>
</junit>
</target>
Execute test by supplying category.nameproperty to ant like this:
通过向category.nameant提供属性来执行测试，如下所示：
ant -Dcategory.name=FastTests test
Using batchtestwill also produce separate JUnit XML report files per test (e.g. TEST-fi.foobar.FastTestClassN.xml).
使用batchtest还将为每个测试生成单独的 JUnit XML 报告文件（例如 TEST-fi.foobar.FastTestClassN.xml）。
