Class MockServletContext

java.lang.Object

org.springframework.mock.web.MockServletContext

All Implemented Interfaces:

ServletContext

public class MockServletContext
extends java.lang.Object
implements ServletContext

Mock implementation of the ServletContext interface.

As of Spring 4.0, this set of mocks is designed on a Servlet 3.0 baseline.

Compatible with Servlet 3.0 but can be configured to expose a specific version through setMajorVersion(int)/setMinorVersion(int); default is 3.0. Note that Servlet 3.0 support is limited: servlet, filter and listener registration methods are not supported; neither is JSP configuration. We generally do not recommend to unit test your ServletContainerInitializers and WebApplicationInitializers which is where those registration methods would be used.

Used for testing the Spring web framework; only rarely necessary for testing application controllers. As long as application components don't explicitly access the ServletContext, ClassPathXmlApplicationContext or FileSystemXmlApplicationContext can be used to load the context files for testing, even for DispatcherServlet context definitions.

For setting up a full WebApplicationContext in a test environment, you can use AnnotationConfigWebApplicationContext, XmlWebApplicationContext, or GenericWebApplicationContext, passing in an appropriate MockServletContext instance. You might want to configure your MockServletContext with a FileSystemResourceLoader in that case to ensure that resource paths are interpreted as relative filesystem locations.

A common setup is to point your JVM working directory to the root of your web application directory, in combination with filesystem-based resource loading. This allows to load the context files as used in the web application, with relative paths getting interpreted correctly. Such a setup will work with both FileSystemXmlApplicationContext (which will load straight from the filesystem) and XmlWebApplicationContext with an underlying MockServletContext (as long as the MockServletContext has been configured with a FileSystemResourceLoader).

Since:

1.0.2

Constructor Detail

MockServletContext

public MockServletContext()

Create a new MockServletContext, using no base path and a DefaultResourceLoader (i.e. the classpath root as WAR root).

See Also:

DefaultResourceLoader

MockServletContext

public MockServletContext(java.lang.String resourceBasePath)

Create a new MockServletContext, using a DefaultResourceLoader.

Parameters:

resourceBasePath - the root directory of the WAR (should not end with a slash)

See Also:

DefaultResourceLoader

MockServletContext

public MockServletContext(ResourceLoader resourceLoader)

Create a new MockServletContext, using the specified ResourceLoader and no base path.

Parameters:

resourceLoader - the ResourceLoader to use (or null for the default)

MockServletContext

public MockServletContext(java.lang.String resourceBasePath,
                          ResourceLoader resourceLoader)

Create a new MockServletContext using the supplied resource base path and resource loader.

Registers a MockRequestDispatcher for the Servlet named 'default'.

Parameters:

resourceBasePath - the root directory of the WAR (should not end with a slash)

resourceLoader - the ResourceLoader to use (or null for the default)

See Also:

registerNamedDispatcher(java.lang.String, javax.servlet.RequestDispatcher)

Method Detail

getResourceLocation

protected java.lang.String getResourceLocation(java.lang.String path)

Build a full resource location for the given path, prepending the resource base path of this MockServletContext.

Parameters:

path - the path as specified

Returns:

the full resource path

setContextPath

public void setContextPath(java.lang.String contextPath)

getContextPath

public java.lang.String getContextPath()

Specified by:

getEffectiveMinorVersion

public int getEffectiveMinorVersion()

Specified by:

getMimeType

public java.lang.String getMimeType(java.lang.String filePath)

This method uses the default FileTypeMap from the Java Activation Framework to resolve MIME types.

The Java Activation Framework returns "application/octet-stream" if the MIME type is unknown (i.e., it never returns null). Thus, in order to honor the ServletContext.getMimeType(String) contract, this method returns null if the MIME type is "application/octet-stream".

MockServletContext does not provide a direct mechanism for setting a custom MIME type; however, if the default FileTypeMap is an instance of javax.activation.MimetypesFileTypeMap, a custom MIME type named text/enigma can be registered for a custom .puzzle file extension in the following manner:

 MimetypesFileTypeMap mimetypesFileTypeMap = (MimetypesFileTypeMap) FileTypeMap.getDefaultFileTypeMap();
 mimetypesFileTypeMap.addMimeTypes("text/enigma    puzzle");
 

Specified by:

getMimeType in interface ServletContext
