ServletUnit example for testing JSP

Question

Can someone give me an example of using ServletUnit to test JSP? Do I need to call registerServlet ()? If so, what class name do I pass?

Answer 1

You do not need to register a Servlet if you intend to use the default Jasper compiler. However, I need Jasper banks and their dependencies on CLASSPATH. The Maven dependencies that I need to get the base JSP for compilation and rendering were:

<dependency>
  <groupId>tomcat</groupId>
  <artifactId>jasper</artifactId>
  <version>3.3.2</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>tomcat</groupId>
  <artifactId>jasper-compiler</artifactId>
  <version>5.5.23</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>tomcat</groupId>
  <artifactId>tomcat-util</artifactId>
  <version>5.5.23</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>tomcat</groupId>
  <artifactId>core_util</artifactId>
  <version>3.3.2</version>
  <scope>test</scope>
</dependency>

I am stuck in a JDK1.4 project, so you can use newer versions. I have not received the standard taglib yet ...
