tests in a JAR file and surefire
Hello everyone
Is it possible to run tests using maven-surefire-plugin when the tests
are in a JAR file ?
I can see that SurefirePlugin uses
org.apache.maven.surefire.battery.DirectoryBattery exclusively and
presume that it's not possible to use tests in JAR.
DirectoryBattery uses DirectoryScanner which checks if the baseDir is a
directory. If not it throws an Exception.
However in the page:
http://maven.apache.org/guides/mini/guide-attached-tests.html
there's written that it's possible to reuse tests using tests-jar.
Can someone tell me what it is meant for and how it can be used in
surefire plugin?
<project>
...
<dependencies>
<dependency>
<groupId>com.myco.app</groupId>
<artifactId>foo</artifactId>
<version>1.0-SNAPSHOT</version>
<type>test-jar</type>
</dependency>
</depdendnecies>
...
</project>
Cheers
Pablo

I can second the usefulness of this. Conformance tests in base
classes are a very useful feature. I implemented these in a C# test
harness at one point; the initial implementation was simply running
all Test-annotated methods in non-abstract classes, regardless of
whether the test methods were inherited or declared there. When I
moved the unit tests to separate test assemblies, the pattern
changed: Instead, a base class would come with an abstract test case:
/* base.dll */
abstract public class Base {
abstract public object Memento { get; set; }
abstract public bool SharesMemento(Base b);
}
/* base_t.dll */
abstract public class BaseTest {
abstract protected Base CreateBase();
[Test] public void TestMemento() {
Base one = CreateBase();
Base two = CreateBase();
two.Memento = one.Memento;
AssertTrue(one.SharesMemento(two));
AssertTrue(two.SharesMemento(one));
}
}
And the subclass would also author a derived test case:
/* sub.dll */
abstract public class Sub : Base {
static counter = 0;
int token = counter++;
override public object Memento {
get { return (object) token; }
set { i = (int) token; }
}
override public bool SharesMemento(Base b) {
return b is Sub && ((Sub) b).token == this.token;
}
}
/* sub_t.dll */
abstract public class SubTest : BaseTest {
abstract protected Base CreateBase() { return new Sub(); }
}
Might a similar pattern work with surefire?
base/
src/test/java/com/example/Base.java
base-conformance-suite/ { depends: main }
src/test/java/com/example/BaseConformanceTest.java
sub/ { depends: base, base-conformance { scope: test } }
src/main/java/com/example/Sub.java { extends: Base }
src/test/java/com/example/SubTest.java { extends:
BaseConformanceTest }
I'm not sure if surefire will find the inherited test methods, though.
Very excited about the TestNG support in surefire 2, BTW. Also, war
merging will find use very swiftly indeed.

For example when you want to test some implementations of given API.
And tests 'bootstraps' implementation using some properties.
Something like TCK for JAXP implementation for example, with tests
starting with -Djavax.xml.parsers.DocumentBuilderFactory=my.jaxp.impl.DBF
(I've never seen a TCK for JAXP but I can imagine that such approach
for testing implementations makes sense).

It means that test can be reused in other projects, so you can extend
or use them from the tests in that project. What is the point of
runing the same tests again in another project?

I could give you my word as a Spaniard.
No good. I've known too many Spaniards.
