Integration Testing in eclipse
Is there any good plugins in eclipse that does integration testing? To test method calls between specified classes.
ASKER
I have two classes, and one of them is calling a method from the other. I want to do an integration testing for this.
Class FirstClass{
public void openDocument(URL url) throws Exception {
// Originally, this method determined external application, with which the document
// should be opened. Which application should open which document type was
// configured in Vmap properties file. As a result, Vmap tried to solve the
// problem (of determining application for a file type), which should better be
// solved somewhere else. Indeed, on Windows, this problem is perfectly solved by
// Explorer. On KDE, this problem is solved by Konqueror default browser. In
// general, most WWW browsers have to solve this problem.
// As a result, the only thing we do here, is to open URL in WWW browser.

if (osName.substring(0,3).equals("Win")) {

propertyString += "_9x";

String command=new String();

I have to test the coupling between these classes.
if (url.getProtocol().equals(
command = "rundll32 url.dll,FileProtocolHandle
} else if (url.toString().startsWith
The method Tools.urlGetFile(url) is in the Tools method. How do i go about with the integration testing. This is what I have done so far but i believe it is more of a unit test than an integration test. Can someone guide me through the integration testing?
@Test
public void T2() throws MalformedURLException {
try{
URL url=new URL("http://www.yahoo.com/edinburgh/lothian/warrender");
m_vmap.openDocument(url);
String urlInTools = m_cCountField.urlGetFile(u

catch(Exception e) {
System.out.println("Error Found: "+e);
assertTrue(true);

Thank you

Thank you. I did something similar to what you have done, is this integration as well?
public void testCouplingPath() throws MalformedURLException{
//Testing for the operating System
String ExpectedSystemOS = "Win";
String osName = System.getProperty("os.name");
String actualSystemOS = osName.substring(0,3);
assertEquals("System OS type",ExpectedSystemOS, actualSystemOS);
//Testing for the url protocol
URL url = new URL("file://www.gambia.west.africa.gm");
String urlProtocol = url.getProtocol();
String expectedProtocol = "file";
assertEquals("URL Protocol",expectedProtocol,urlProtocol);
//testing for the Tools.urlGetFile(url)
String urlGetFileReturns = Tools.urlGetFile(url);
String expectedURLReturn = "\\\\www.gambia.west.africa.gm";
assertEquals("urlGetFile return answer",expectedURLReturn,urlGetFileReturns);
}
That looks like a good test but it's still really just a unit test for urlGetFile() and some parts of the openDocument() method.
I think to make it a full integration test you just need to add a call to:
FirstClass.openDocument(ur
probably at the end of the test.
Since openDocument() doesn't actually return anything, it's hard to test it's behavior - except that a call to it doesn't throw an exception.

There's nothing about JUnit that limits you to writing unit tests. You can easily write integration tests - where your test classes just calls to methods in other classes.
