Testing Exceptions on the NetBeans Platform on Maven

Microservices! They are everywhere, or at least, the term is. When should you use a microservice architecture? What factors should be considered when making that decision? Do the benefits outweigh the costs? Why is everyone so excited about them, anyway?  Brought to you in partnership with IBM.

Testing for expected exceptions does not work correctly in junit <= 4.5

Junit4 provided the functionality to test for expected exceptions. Expected exceptions can be tested with the method annotation @Test:

    @Test(expected=SomeException.class)
public void testSomeException() throws SomeException {
// some code that is expected to throw SomeException
}

However, in junit version < 4.5  this does not work like it should (not at all, tests will fail if expected exception gets thrown). The Maven module for the NetBeans extention for junit has a dependency on a wrapper around junit version 4.5. To be able to test for exceptions, a higher version of junit is needed. This is easily achieved by excluding the dependency on the junit 4.5 wrapper and explicitly declaring a dependency on a junit with a higher version (like 4.8.2 in our case).

            <dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
<version>4.8.2</version>
</dependency>
<dependency>
<groupId>org.netbeans.api</groupId>
<artifactId>org-netbeans-modules-nbjunit</artifactId>
<version>${netbeans.version}</version>
<scope>test</scope>
<exclusions>
<exclusion>
<artifactId>junit-4.5</artifactId>
<groupId>org.netbeans.external</groupId>
</exclusion>
</exclusions>
</dependency>
