Method Detail

getRequest

public javax.servlet.http.HttpServletRequest getRequest()

Returns the request to be processed by the servlet or filter.

---

getResponse

public javax.servlet.http.HttpServletResponse getResponse()

Returns the response which the servlet or filter should modify during its operation.

---

service

public void service()
             throws javax.servlet.ServletException,
                    java.io.IOException

Invokes the current servlet or filter.

Since:

---

getServlet

public javax.servlet.Servlet getServlet()
                                 throws javax.servlet.ServletException

Returns the selected servlet, initialized to provide access to sessions and servlet context information. Only valid to call if isFilterActive() 55 returns false.

---

getServletResponse

public com.meterware.httpunit.WebResponse getServletResponse()
                                                      throws java.io.IOException

Returns the final response from the servlet. Note that this method should only be invoked after all processing has been done to the servlet response.

---

getFrame

public com.meterware.httpunit.FrameSelector getFrame()

Returns the target frame for the original request.

Since:

1.6

---

pushIncludeRequest

public void pushIncludeRequest(javax.servlet.RequestDispatcher rd,
                               javax.servlet.http.HttpServletRequest request,
                               javax.servlet.http.HttpServletResponse response)
                        throws javax.servlet.ServletException

Adds a request dispatcher to this context to simulate an include request.

---

pushForwardRequest

public void pushForwardRequest(javax.servlet.RequestDispatcher rd,
                               javax.servlet.http.HttpServletRequest request,
                               javax.servlet.http.HttpServletResponse response)
                        throws javax.servlet.ServletException

Adds a request dispatcher to this context to simulate a forward request.

---

popRequest

public void popRequest()

Removes the top request dispatcher or filter from this context.

---

isFilterActive

public boolean isFilterActive()

Returns true if the current context is a filter, rather than a servlet.

Since:

1.6

---

getFilter

public javax.servlet.Filter getFilter()
                               throws javax.servlet.ServletException

Returns the current active filter object. Only valid to call if isFilterActive() 55 returns true.

Since:

1.6

---

getFilterChain

public javax.servlet.FilterChain getFilterChain()

Returns the current filter chain. Only valid to call if isFilterActive() 55 returns true.

Since:

1.6

---

pushFilter

public void pushFilter(javax.servlet.ServletRequest request,
                       javax.servlet.ServletResponse response)

Pushes the current filter onto the execution stack and switches to the next filter or the selected servlet. This can be used to simulate the effect of the doFilter 55 call.
Note: this method specifies javax.servlet.ServletRequest and javax.servlet.ServletResponse because those are the types passed to Filter.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain)>Filter.doFilter(javax.servlet.ServletRequest, javax.servlet.ServletResponse, javax.servlet.FilterChain) 55 ; however, HttpUnit requires the objects to implement javax.servlet.http.HttpServletRequest and javax.servlet.http.HttpServletResponse because they will eventually be passed to an javax.servlet.http.HttpServlet.

Since:

1.6
